PrefaceThis manual provides information for system integrators who are designingsystems for high-definition (HD) and standard-definition (SD) digital videocontent where Tektronix ECO422D SD/HD Changeover Units and video syncpulse and signal generators are to be deployed.

Changeover unit models This manual describes how to integrate a system using a TektronixECO422D SD/HD Changeover Unit.

If you are integrating a system using a Tektronix ECO8000 Series AutomaticChangeover Unit, see the system integration manual for the ECO8000 Seriesinstruments (Tektronix part number 077-0877-xx).

Stay GenLock®Stay GenLock® is a digital genlock technology developed by Tektronix for thesignal generators covered by this manual. It provides additional robustness andstability for genlocked SPGs, as in a master/slave configuration. (See page 103,Using Stay GenLock®.)

Supported productsThe information in this manual covers the Tektronix products described below.

ECO422D SD/HDChangeover Unit

The ECO422D is a highly versatile sync changeover unit designed for use in aserial SD/HD digital television environment. The ECO422D will accommodatecomponent or composite serial digital video signals, AES/EBU digital audio,tri-level sync, and analog black-burst signals. This flexibility makes the ECO422Dideal for both the mixed-format and all-digital television facility.

The ECO422D provides eleven user-configured channels, each channel consistingof primary and backup inputs, and an output. These channels can be set as follows:

Six channels can be set for high-definition serial digital video,standard-definition serial digital video, AES/EBU digital audio, tri-level sync,and PAL or NTSC analog black burst

Five channels may be set for standard-definition serial digital video,AES/EBU digital audio, tri-level sync, and PAL or NTSC analog black burst

Channel configuration is by internal DIP switch. The signal amplitude faultdetection level follows the setting of the channel configuration switches. Detectionon individual channels may be disabled, giving the option of disabling changes tothe backup unit on failure of signals not critical to the facility operation.

Preface

When operated in the switch-on-fault mode, the ECO422D will automaticallyselect the backup sync source should any of the primary inputs fail. However, inthe unlikely event both sync sources are faulty, the ECO422D will not alternatebetween the two sources. If necessary, this function may be overridden with themanual sync source selection. Manual source selection also facilitates periodictesting of the changeover function. Switching is by mechanical relay with allchannels switched simultaneously.

The Electrical Fast Switch function, available with Opt. ELSW, improves thechangeover switching speed between inputs, and replaces the mechanical relay onchannels 4-6. Using this type of switch minimizes disturbance when switchingbetween primary and backup inputs. With Option ELSW, channels 4-6 can acceptonly a black-burst or tri-level sync signal.

Front-panel controls are provided for source selection, operating mode, resettingthe fault indicators, and for disabling the front-panel controls. LED indicatorsare also provided. Indication of fault and unit on line is also available throughthe remote connector.

SPG600/300 Sync PulseGenerators

The SPG600 and SPG300 Sync Pulse Generators provide synchronization andtest signals for both traditional analog and mixed digital and analog facilities, inboth NTSC/525 and PAL/625 environments. These products are ideal as a stablemaster sync signal, which is critical in digital broadcast environments.

When these instruments are configured for Stay GenLock mode, a momentary lossof synchronization at the genlock reference input will not cause a disturbance inthe test signal and black outputs of the unit. When the genlock signal is reapplied,the SPG system will gradually reacquire lock. This will cause little disruption inthe outputs of the device and will not cause any noticeable glitches in the outputsof the SPG.

The Genlock source can be NTSC/PAL Black Burst, NTSC/PAL Sync, or CW.When using CW lock, the Genlock timing can be adjusted on all the NTSC orPAL color frames.

Preface

SPG8000 Master Sync /Clock Reference Generator

The SPG8000 is a precision multi-format video signal generator, suitable formaster synchronization and reference applications. It provides multiple videoreference signals, such as black burst, HD tri-level sync, and serial digital andcomposite analog test patterns, and it provides time reference signals such as timecode and NTP (Network Time Protocol).

The base configuration includes three sync outputs that can be configured withindependent output formats (NTSC/PAL black burst and/or HD tri-level sync)and independently adjustable timing offsets. With the BG option, four moreanalog outputs can be added. A high-accuracy, oven-controlled crystal oscillatorprovides a stable frequency reference for the system, or the pass-through genlockinput can be used to lock to an external video reference or 10 MHz continuouswave signal. The SPG8000’s Stay GenLock® feature avoids “synchronizationshock” if the external reference suffers a temporary disturbance, by maintainingthe frequency and phase of each output signal. When the external reference isrestored, Stay GenLock® ensures that any accumulated clock drift is removed byslowly adjusting the system clock within standard limits instead of “jamming”back to the correct phase.

Time reference outputs are available in multiple formats. Three independentlinear time code (LTC) outputs are available, and a fourth LTC connection can beused as input or output. Each LTC output has independent frame rate selection,time source (time-of-day or program time) and time zone offset. Verticalinterval time code (VITC) is available on each NTSC or PAL black output, alsowith independent time sources and offsets. The SPG8000 can also serve as aNetwork Time Protocol (NTP) server, providing the time-of-day reference tonetwork-attached devices.

Optional GPS Receiver. The GPS option adds an internal GPS receiver to theSPG8000. When connected to an external antenna that supplies the standard GPSRF signal, the SPG8000 can utilize the GPS system’s stable frequency reference.The GPS signal also includes a precise time-of-day reference that can be used forall time code outputs. Similar to the Stay GenLock® feature, the SPG8000 canmaintain the video frequency and phase when the GPS signal is interrupted, andthe Holdover Recovery mode will ensure a shock-free re-alignment of frequencyand phase when the GPS signal is restored.

TG700 and TG8000Multiformat Test Signal

Generators

The TG700 and TG8000 are multiformat, analog and digital, precision signalgeneration platforms. Designed with the changing needs of the video industry inmind, the they offer sync pulse generation and test signal generation for a widearray of analog, serial digital, and digital high-definition formats.

The instruments have a modular architecture that offers the flexibility to meet thesingle-format and growing multiformat needs of the video professional. Theyallow up to four of the following modules to be fitted in the mainframe.

AGL7 module. The TG700 and TG8000 have a high stability reference. TheAGL7 Analog Genlock Module adds the capacity to lock to a variety of signals,which makes the TG700 and TG8000 ideal solutions as the master house referenceor slave reference for broadcast and production/post-production applications.

Three black outputs are available and are selectable for HDTV tri-level or NTSCor PAL. Additionally, the AGL7 can lock to a variety of formats to includeNTSC/PAL black and HDTV tri-level as well as 1, 3.58, 4.43, 5, and 10 MHz CW.

When the AGL7 is configured for Stay GenLock® mode, a momentary loss ofsynchronization at the genlock reference input will not cause a disturbance in thetest signal and black outputs. When the genlock signal is reapplied, the AGL7 willgradually reacquire lock, causing little or no disruption to devices synchronizedto the reference.

GPS7 module. The GPS7 GPS Synchronization and Time Code Module includesan integrated GPS receiver which can serve as the system timing reference.Synchronization to the GPS timing signals ensures long-term stability, and videoframe alignment between independent systems. The GPS RF coaxial signal inputis available with 3.3 V or 5 V DC power output for the GPS antenna enabling theuser to select from a variety of GPS antennas available on the market.

The GPS7 also includes a genlock input with VITC reader, enablinguser-selectable configuration of the TG700 and TG8000 as the master referenceor as a slave to another master, depending on the dynamic requirements of eachproduction. The GPS7 module will maintain system timing by Stay GenLock®technology even during periods of GPS signal loss or genlock signal loss. Threeblack outputs are available and are selectable for HDTV tri-level, NTSC, or PAL.

Time code source can be selectable to the time-of-day (with user-selectableoffsets) from GPS receiver, internal source, VITC on the reference input, LTCinput, or to a "program time" counter for elapsed-time time code. The DaylightSavings Time (DST) adjustment could be recurring scheduled, based on calendarrules. Time code is available as VITC on black outputs (GPS7, BG7), as AncillaryTime Code (ATC) (HDVG7, HD3G7), from four independent LTC outputs(GPS7), and as a response to time requests on a Simple Network Time Protocol(SNTP version 3.0) Server.

InstallationThis section describes how to install each of the products covered by this manual.

ECO422D installationRackmounting The ECO422D is shipped with the hardware for rackmounting. The instrument

fits in a standard 19-inch rack. Spacing between the front rails of the rack mustbe at least 17.75 inches to allow clearance for the slide-out tracks. Rack slidesconveniently mount in any rack that has a front-to-rear rail spacing between15.5 and 28 inches. The ECO422D requires six inches of clearance betweenthe instrument rear panel and any rear cabinet panel for connector space and toprovide adequate air circulation.

Mounting the slide tracks. Mount the rails using the enclosed hardware. (SeeFigure 9.) Rail mounting details for both deep and shallow racks are also shown.(See Figure 7.) (See Figure 8.) Front mounting details are also shown below.(See Figure 6.) Make sure that the stationary sections are horizontally aligned,level, and parallel.

Installing the Instrument. Perform the following steps to install the instrument inan equipment rack. (See Figure 10.)

1. Pull the slide-out track section to the fully extended position.

2. Insert the instrument chassis sections into the slide-out sections.

3. Press the stop latches and push the instrument toward the rack until the latchessnap into their holes.

4. Again press the stop latches and push the instrument fully into the rack.

5. Tighten the front-panel knurled retaining screw.

Removing the instrument. Perform the following steps to remove the instrumentfrom an equipment rack. (See Figure 10.)

1. Loosen the front-panel knurled retaining screw.

2. Grasp the front handles and pull the instrument out until the slide sectionslatch. The instrument is firmly held in this position.

3. To completely remove the instrument from the rack, first be sure to disconnectall cabling.

4. Press both stop latches (visible in the stop-latch holes), and then carefullyslide the instrument free from the rackmount tracks.


Installation

Figure 10: ECO422D installing or removing the rack slides

Rack adjustments. After installation, if not properly adjusted, the slide tracks maybind. To adjust the tracks, slide the instrument out about 10 inches, slightly loosenthe screws holding the tracks to the front rails, and allow the tracks to seek anunbound position. Retighten the screws and check the tracks for smooth operationby sliding the instrument in and out of the rack several times.

Once the instrument is in place within the rack, tighten the knurled retainingscrew to fasten it securely into the rack.

Rack slide maintenance. The slide-out tracks do not require lubrication. The darkgray finish on the tracks is a permanent, lubricated coating.

Cable installation The BNC connectors are tightly spaced on the ECO422D rear panel. You mayfind it necessary to use a BNC Cable Tool to remove or install cables (example:Trompeter RT-1L).

NOTE. A source transition can occur if the channel output amplitude is reduced.This can be caused by over-termination, cable damage, or an accidental short toground. A channel’s selected input and its output are directly connected throughan internal relay. Therefore, the ECO422D detects an output reduction as aninput reduction. This does not apply to the three Option ELSW channels, whichare buffered.

To avoid this problem, work on an output only when the ECO422D is not inoperation. Disconnect the output cable from the ECO422D before working onthe cable, and verify proper termination before reconnecting the cable to theECO422D.


Installation

User switch configuration Remove the small panel on the top cover of the instrument to access the userconfiguration switches. (See Figure 11.) These switches select the signal typechecked on a channel by setting the amplitude comparison level.

Only one switch from each DIP package should be enabled (closed) for eachchannel, except for attenuation (DIP 8 on switches S7 through S11), which isallowed to be combined with either of the user-defined levels.

CAUTION. Make sure that any channel that is not in use has checking disabled.If checking is not disabled, errors will always be generated and the ECO422Dwill not operate properly. No error checking also allows the maximum voltage,current, and frequency to pass through the ECO422D.

Installation

Attenuation. Attenuation allows larger signals to have their signal level checked.The attenuator adds about 14 dB (x5) attenuation to the signal level beingchecked. This has no effect on the level of the output signal and only extends therange of the check circuitry. Use this in conjunction with large H-sync pulses toincrease the accuracy on the level check. Only use this switch in conjunctionwith the User Defined Levels.

User configuration switch (S14 – 8). This switch determines how the ECO422Dresponds to faulty signals, either Normal (closed) or Override (open). (SeeFigure 11 on page 19.)

For Normal operation, the user cannot switch to a bad signal whether theinstrument is in manual or auto switch mode. For example, the ECO422D is inmanual mode and the Primary signal is bad, while the Backup signal is good. Ifthe user presses the Sync Source button, the output will be the Backup signal. Ifthe user presses the Sync Source button again, the output continues to be theBackup signal. It will not change to Primary until the signal is good and thefault indicator is reset.

In the Override mode, the user can manually switch to a “bad” signal, with Automode disabled.

Reference level adjustments (R266 and R265). These two adjustments set thereference level for the two user-defined signal options. Select these levels withDIPs 6 (R266) and 7 (R265) of the Channel Configuration switches. These allowthe user to set their own signal switching level for special applications. Twoexamples of signals that may require checking are an active video signal or an HSync signal. (See page 23, Adjusting the user-defined threshold levels.)

Power-on delay switch (S13). This hex switch (See Figure 11.) sets the delayduration between the time power is applied and the time the ECO422D startserror detection. Each position of the switch increments the delay approximately30 seconds (position 0 = no delay). The factory setting is position 5, whichprovides a delay of slightly under three minutes.

This switch is not available on instruments with serial number B029999 andearlier.

Adjusting the user-definedthreshold levels

The User-defined Threshold Levels are the two levels available from UserConfiguration switches 6 and 7. They are available so that the user can trigger onsignal levels other than the seven predefined levels.

Required equipment. In order to set the Threshold Levels, you need:

A signal source to provide two good versions of the type of signal you want tocheck (example Tektronix TSG130A)

A step attenuator (example: 847 Attenuator from KAY Elemetrics)

ECO422D Changeover Unit

(Optional) A waveform monitor (example: Tektronix 1745A) or oscilloscope

Procedure. The following adjustment example sets switch 7 for NTSC activevideo with the threshold set for a 3 dB down color bar.

1. Connect the equipment as shown in the following figure.


Installation

2. Set all of the User Configuration switches to “open” except for S1-7 (forchannel 1). (See Figure 11 on page 19.)

3. Set all S14 switches to “closed.”

4. Set the ECO422D to Primary Sync Source.

5. Set the ECO422D Auto Switching to “Switch on Fault.”

6. Set the step attenuator to 0 dB of attenuation.

7. Turn the potentiometer R265 fully. (You are attempting to allow the minimumsignal level to pass through before the threshold is reached.)

8. Press the fault indicator Reset button (this clears any errors).

9. Check the fault indicator for an error indication on either the Primary orBackup channels. If there are no faults, then proceed to the next step.Otherwise, try rotating the potentiometer in the other direction. (You aretrying to get the minimum signal level to pass through before reaching theswitching threshold.)

10. Set the step attenuator to 3 dB of attenuation (or whatever attenuation isrequired for your application).

11. Check to see that the sync source has not changed to Backup and no faultsare on the Primary channel.

NOTE. For information on how to install the SPG300 into a standard 19-inchequipment rack, refer to the Instructions included in the rackmounting kit.

Minimum tool and equipment list. The following tools are required to install therackmounting hardware into the equipment rack. All tools are standard toolsthat are readily available.

Table 16: SPG600 tools required for rackmount installationName DescriptionScrewdriver handle (magnetic) Accepts 1/4 inch hex-head driver tipsNo.2 Phillips tip Phillips-driver tip for M3 size screw heads3/8 inch wrench

WARNING. To prevent the rackmounted instrument from tipping forward onto theoperator, install the instrument so that the operator will be able to access all of itsrear-panel connectors without pushing down on the instrument.

Verify that the rack does not become unstable with the instrument fully extended.Do not leave the instrument extended when finished accessing the rear panel.


Installation

To install the rackmount rails.

1. Measure the distance between the front and rear rail of the equipment rack.

2. Align the rear bracket to the right rail. Notice that the rear bracket has multiplepairs of mount-through holes. When aligning the bracket and rail, be sure toselect a pair of holes that mount the rear bracket so that the flange-to-flangedistance matches the front rail to rear rail spacing of the rackmount rack justmeasured in step 1. (See Figure 12.)

3. Using a screwdriver with a #2 Phillips tip, attach the rear bracket to the rightrail using two 10-32 screws and a bar nut. Leave the screws loose so that youcan adjust the overall length of the rail assembly in the rack.

4. Repeat steps 2 and 3 to assemble the left rail assembly.

Figure 12: Assembly and mounting of rails


Installation

5. Select a 1/2 inch spaced hole in the front rack.

6. Select the mounting method according to your rack type:

Mount the rails with their front and rear flanges outside the front and rearracks and add a bar nut to the installation only if the rails have untappedholes.

Mount the rails with their front and rear flanges inside the front and rearracks and add a bar nut. This mounting method assumes untapped holes.

7. Using the method and hardware determined from step 2, attach the right railassembly to the equipment rack front and rear rails. The screws should befully, but lightly, seated so that you can adjust the rack later.

8. Tighten the screws left loose when you assembled the rails, applying28 inch-lbs of torque, to fix the front to rear flange spacing of the rail assembly.

9. Repeat steps 5 through 8 to mount the left rail assembly.

To install the instrument into the equipment rack.

WARNING. To prevent injury during product installation, use care not to pinchhands or fingers in the rails and slides.

1. Insert the instrument left and right slides into the ends of the rack rails whiletilting the long handle part of each lever upward. (See Figure 13.)

NOTE. Make sure to insert the instrument slides inside the inner rack rails. Youmay also need to tilt rear of the instrument up or down at a slight angle to fitthe slides into the rails.

2. Push the instrument into the rack until it stops.

CAUTION. To prevent damage to the instrument and rackmount, do not force theinstrument into the rack if it does not slide smoothly. The rails assembly may needto be adjusted to resolve the problem.

3. Retighten any loose screws and push the instrument all the way into the rack.If the tracks do not slide smoothly, readjust the rail assemblies.

4. When adjusting is completed, tighten all rail assembly 10-32 screws using28 inch-lbs of torque.

5. If the instrument has knob screws on the front corners, tighten them so thatthey are secured in the rack.

GPS antenna requirements(Option GPS only)

When Option GPS is installed, an external antenna connection to the instrument isrequired to receive signals from satellites. (See page 49, SPG8000 connections.)

Oven oscillator calibration You can calibrate the internal oscillator frequency at any time after you install theinstrument in its operating environment and allow it to reach a stable operatingcondition. When Option GPS is installed, you can perform this calibration whilethe instrument is in service.

If Option GPS is not installed, you can calibrate the oscillator using a referencesignals such as NTSC Burst or CW, but only when the instrument is not in service.See the SPG8000 Technical Reference manual for instructions on how to calibratethe oven oscillator when a GPS signal is not available.

NOTE. Perform the internal oscillator frequency calibration at least once a yearto compensate for oscillator drift.


Installation

To calibrate the internal oven oscillator frequency. Perform the followingprocedure to set the internal frequency of the instrument internal oscillator.This adjustment stores the current frequency of the oscillator for use when theinstrument is set to Internal mode. This procedure can be done without anydisruption to operation and is best performed in the operating environment ofthe instrument.

CAUTION. To prevent inaccurate calibration, be sure the instrument is war
