In order to prevent or minimize mutual interference of several devices,a 220V AC stabilized-voltage power is suggested to be powersupply

Imperfect or wrong power ground may result in instrument damage or even personal injury. It is necessary to adopt designated powersource for synthesized sweep signal generator to make sure ground wires of power source and power supply in good connection. Adoptpower socket with ground protection, don't substitute external cable for ground protection wire.

1.2.4. Anti-static protection

Static may cause great damage to operator and the instrument. All operations of the instrument should be done on anti-static workbench.Generally users should take anti-static measures: anti-static table mat and wrist strap or combination of anti-static floor and ankle strap.Anti-static protections should provide at least 1MΩ isolation resistance from ground to ensure the user's safety.

The follow anti-static measures should be taken to reduce static damage:

a) Make sure all the instruments are correctly grounded to prevent static generation.

b) Operators should wear anti-static wrist band before any operation.

Anti-static measures above are not suitable for voltage of more than 500V.

4.2.Senior operation guidance

This part discusses complex operations of S1103 synthesized sweep signal generator.

4.2.1. Select ALC bandwidth

Under internal stable amplitude mode, signal source adopts automatic level control (ALC) circuit before RF output. ALC bandwidth has fiveoptions: auto, 100Hz, 1kHz, 10kHz and 100kHz. Under auto mode (reset option), signal source selects ALC bandwidth automaticallyaccording to configuration and setting.

Press [Power]>[Page Up/Page Down 1/3]>[Page Up/Page Down 2/3]>[ALC bandwidth] to select 100Hz, 1kHz, 10kHz, 100kHz or auto.Substitute auto ALC bandwidth of signal source for given option. Limited bandwidth or narrow bandwidth will lengthen ALC’s sampling timebut giving RMS value of signal more precisely.

4.2.2. External stable amplitude of synthesized sweep signal generator

4.2.2.1. Brief description

Under external stable amplitude, output power of synthesized sweep signal generator is detected by external probe, detection voltage issent back to stable amplitude circuit of synthesized sweep signal generator, and output power is calibrated automatically to ensureconsistent power on detecting points.

4.2.2.2. Stable amplitude of detector/coupler/power dividerFigure 4-2 shows a typical setting of external stable amplitude under external stable amplitude, power level is fed back

external negative voltage output detector other than internal detector. Feedback voltage control ALC system thus controlling

output power.

Figure 4-2 external stable amplitude of ALC circuit

1.Set external stable amplitude

1) Connect instrument as Figure 4-2

2) Press [Power] key, [Page Up/Page Down]

3) Select [Select Stable Amplitude Mode] soft key, select [External].

2.Set coupling parameter

Press [Power] key, press [External Detection Coupling Factor] soft key, input [20] [dBm] in current display. (Coupling factor of directionalcoupler is 20dB)

3.Stable amplitude of step attenuator

Some external stable amplitude applications adopt low power output of synthesized sweep signal generator. For all the external stableamplitude points of ALC system, synthesized sweep signal generator shifts into attenuator manual mode automatically.

For example, we need an amplifier with measuring increment of 30dB and stable amplitude output of -10dBm, thus synthesized sweepsignal generator output is -40dBm. For certain frequency, the power level exceeds control range of ALC modulator. In such circumstance,

Tel: 886.2.2175 2930 Email: [email protected]

www.salukitec.com

48

the displayed message in information area is non- stable amplitude warning. Add attenuator of 40dB in ALC loop of 0dBm, 0dBm is withinthe stable amplitude range of ALC.

In order to optimize display accuracy and noise base, ALC level should be more than -10dBm. This is can be achieved by step attenuator.The value of step attenuator is a multiple of tens digit of output power. For example, when output power is -43dBm, attenuation is 40dB,ALC power is -3dBm.

a) Press [Power] key, set [Power Level] as [-3] [dBm].

b) Select [Attenuator Setting Manual/Auto], input [40] [dBm] in input area of display area

4.Stable amplitude of MMW source module

Stable amplitude of MMW signal source module is similar with stable amplitude of external detection; power level feedback signal to ALCcircuit derives from MMW signal source module other than built-in detector. Stable amplitude of power output of MMW signal sourcemodule is achieved with source module interface connector on rear panel of signal source for feedback signal.

4.2.3. Mixer mode/backward power impact

Manually configure attenuator is only applicable to synthesized sweep signal generator with step attenuator option.

Attenuator manual is used for mixer test. In the example of Figure 4-3, output power of synthesized sweep signal generator is -8dBm,under internal stable amplitude mode, attenuation of attenuator is 0dB. Power level of ALC is -8dBm. LO drive of mixer is +10dBm.Isolation from LO to RF output of synthesized sweep signal generator is 15dB. Power from LO to output end of synthesized sweep signalgenerator by feeding through is -5dBm, through attenuator without loss to internal detector. For certain frequency, most of energy canenter into detector. But input response of detector is irrelevant with frequency, the energy makes stable amplitude circuit of synthesizedsweep signal generator decrease power output. In this example, backward power is actually more than power level of ALC, forcing poweroutput of synthesized sweep signal generator turned off.

In the example of Figure 4-4, power output generated by attenuator manual mode is -8dBm. Here, attenuation is 10dB, power level of ALCis +2dBm, LO power of mixer is 10dBm. Attenuator: backward power of attenuation LO of 10dB, backward power of LO is -5dBm, thusonly backward power of -15dBm goes through detector, desirable +2dBm of ALC level and undesirable-15dBm of backward power goesthrough detector. Difference value of 17dB leads to drifting of 0.1dB for synthesized sweep signal generator. Set synthesized sweep signalgenerator under attenuator manual mode.

a) Press [Power] key

b) Select [attenuator setting manual/auto], input [10] [dBm] in input area of display area. Two results are achieved: attenuatormode of ALC system is manual, value of attenuator is 10dB in this example.

c) Select [Power Level] soft key, input [2] [dBm] in displayed input area.

4.2.4.3. Calibrate power meter manually

Example 2: input flatness calibration data manually when stepped measurement

This example discusses how to calibrate flatness manually with synthesized sweep signal generator and power meter, and also twofeatures of synthesized sweep signal generator. Frequency following function simplifies input procedure. Soft menu can set a testfrequency list.

Frequency following can set synthesized sweep signal generator at dot frequency test frequency automatically, this frequency is equal tocurrent active frequency in flatness calibration list. Move calibration list with direction keys on front panel and input calibration data ofresponse frequency. Do not exit from calibration list; test frequency of synthesized sweep signal generator is immediately correctedaccording selected calibration frequency. In order to simplify data input procedure further, input calibration data into flatness calibration list,rotate the knob on front panel until power meter displays set power level. Flatness calibration algorithm automatically calculatesappropriate calibration parameter and input into calibration list. If calibration data is available, input the data into calibration list with keyson front panel of synthesized sweep signal generator.

You can input test frequency in any order under list mode function. Set power offset or residence time step in the order of input.

Power meter calibration function has a capacity of storage and can input frequency list into calibration list. In the process of data input forpower meter calibration function, power offset is not activated, so calibration data with or without offset is the same. If user flatnesscalibration and list mode (with offset) are activated, calibration power of synthesized sweep signal generator is calibrated based on thesum of offset and calibration data for each test frequency. Make sure power level is within ALC.

The synthesized sweep signal generator employs intelligent instrument hardware platform based on modern computer technology andembedded multiple task operating system, and divides its hardware and software into multiple functional independently modules based onmodularized design concept. Hardware of synthesized sweep signal generator is composed of main control computer, high-purityfrequency synthesis, microwave MMW channel, drive and control of microwave MMW, digital MMW, power supply and display. Forefunctional block diagram of hardware of synthesized sweep signal generator refer to Figure 6-1.

Intelligent backbone of main control computer of synthesized sweep signal generator receives and deals with internal/external commands,direct function units to work in good order in order to complete special functions with the help of software.

Microwave MMW channel realizes generation and conditioning of microwave MMW signal. Signal procedures are as below:

Low noise YIG oscillator outputs fundamental signal of 3 - 10GHz under control of main control computer and drive circuit, then signal of 5- 10GHz is processed for frequency doubling with 20GHz frequency doubling filtering unit to obtain signal of 10 - 20GHz. In the meanwhilesignal of 3 - 10GHz is coupled into 2 circuits of signal, one is sent to sampling down-conversion to obtain feedback signal requested forsynthesis of high-purity frequency, the other is sent to low waveband unit for frequency division and frequency mixing to obtain signaloutput below 3GHz. 2 subharmonic suppression after frequency doubling is realized in 20GHz frequency doubling filtering unit. Output 3 -20GHz of signal of main circuit of 20GHz frequency doubling unit enters into modulation

In case of abnormality, check external wires for any failure; power on theinstrument again and restart it after trouble-shooting.

8.1.2. Fan does not run after start

If the fan does not turn after start, check for any obstacle or much dust in the fan; if yes, switch off the fan for removal of the obstacle ordust. After that, power on and start the fan again; if it still does not turn, return it to the manufacturer for repair or replacement.

8.1.3. Loss of lock (LOL) of reference loop

A temporary LOL of the reference loop may occur if the signal generator is started under the non-standby state, i.e. cold start. At thismoment, an alarm indication "Time base not hot" will appear on the front panel. Ignore it because it will disappear 10min after the start. If"LOL of reference loop" appears in the alarm indication area of the display screen, a failure exists. Perform the following operations incase of a failure:

a) [System]

b) [System Maintenance]

c) [Self-test] 50, press [Any unit key]

d) [Start self-test]

Press the Up/Down key to find out and select the failed self-test and then proceed to the following operations:

a) [Single-step test On/Off]

b) [All displayed results failed]

c) [Start self-test]

d) If a self-test includes lots of steps, press the [Continue] key until the self-test is finished.

e) Record measured values of each step and return them to the manufacturer.

8.1.4. LOL of LO

If the LOL of LO appears in the alarm indication area of the display screen, perform the following operations:

a) [System]

118

b) [System Maintenance]

c) [Self-test] 130, press [Any unit key]

d) [Start self-test]

Press the Up/Down key to find out and select the failed self-test and then proceed to the following operations:

a) [Single-step test On/Off]

b) [All displayed results failed]

c) [Start self-test]

d) If a self-test includes lots of steps, press the [Continue] key until the self-test is finished.

e) Record measured values of each step and return them to the manufacturer.

8.1.5. LOL of YO loop

If "LOL of YO loop" appears in the alarm indication area of the display screen, perform the following operations:

a) [System]

b) [System Maintenance]

c) [Self-test] 170, press[Any unit key]

d) [Start self-test]

Press the Up/Down key to find out and select the failed self-test and then proceed to the following operations:

a) [Single-step test On/Off]

b) [All displayed results failed]

c) [Start self-test]

d) If a self-test includes lots of steps, press the [Continue] key until the self-test is finished.

e) Record measured values of each step and return them to the manufacturer.

Considering that the LOL of LO will cause the LOL of YO ring, in case of simultaneous occurrence of them, the former should be handledfirst, and then check for the LOL of YO loop.

8.1.6. Unstable amplitude

If the power level of signal generator is beyond the index range, an indication of "Unstable amplitude" may appear, which is normal andused to notify users of unstable output power of the signal generator.

If "Unstable amplitude" appears in the alarm indication area of the display screen, perform the following operations:

a) [System]

b) [System Maintenance]

c) [Self-test] 460, press[Any unit key]

d) [Start self-test]

Press the Up/Down key to find out and select the failed self-test and then proceed to the following operations:

a) [Single-step test On/Off]

b) [All displayed results failed]

119

c) [Start self-test]

d) If a self-test includes lots of steps, press the [Continue] key until the self-test is finished.

e) Record measured values of each step and return them to the manufacturer.

8.1.7. Failure in RF output power

Check the RF switch display on the front panel display screen. If the RF Off is shown, press [RF Switch] to allow the RF output display toshow RF On.

1) Low RF output power

Check whether a power offset indication exists in the power display area of the front panel display screen; if yes, the power offset hasbeen set. The power offset may change values shown in the power area of the display screen, but may not affect the output power. Thepower displayed is equivalent to the actual output power of a signal source plus the offset value.

Perform the following operations to cancel the power offset:

Press[Power]>[Power Offset Switch]. When "Off" in the power offset menu is highlighted, the power offset indication in the power displayarea disappears, indicating that the power offset function is inactivated.

2) Failure to detect any signal via a spectrum analyzer

In case of simultaneous operation of both a signal generator and a spectrum analyzer without the pre-selecting function, the backwardpower effect may cause failure in RF output of the signal source. For some spectrum analyzers, a LO feed through of up to +5dBm mayexist at the RF input port at certain frequencies. If the difference of frequency between the LO feed through and RF carrier is less thanALC bandwidth of the signal generator, the backward power of the LO may cause amplitude modulation to RF output of the signalgenerator. The backward power effect can be handled by one of the following two ALC operating modes: set the ALC loop state to On andset the ALC to allow it to work at the manual power search mode.

8.1.8. No modulation of RF output

Check the modulation switch display on the front panel display screen. If the Modulation Off is shown, press [Modulation Switch] key toallow the modulation output display to show Modulation On. Even though various modulations can be set and started in case ofmodulation Off, the RF carrier cannot be modulated unless the modulation switch is set to On.

8.1.9. Stop of sweep

Considering that the current sweep state can be indicated by a shadowed rectangle in the progress bar, it is possible to check theprogress bar and confirm whether the sweep is underway. If a sweep is stopped, perform the following checks:

Check whether a sweep is started and performed at the continuous sweep mode. In case of a singular sweep mode, confirm that thesingular sweep soft key of the sweep control has been pressed for at least one time after completion of the last sweep.

Check whether the signal generator receives a proper sweep trigger signal. After setting the sweep triggering mode to Auto, confirmwhether stop of sweep is caused by any missing sweep trigger signal.

Check whether a residence time is set properly by trying to set it to one second. Then confirm whether the failure to see the residence timeis caused by a short or long residence time.

Check whether at least two points are covered in a step sweep or list sweep.

8.1.10. No response of a signal generator to a front panel key

In case of no response of a signal generator to a front panel key, check whether the signal generator works at the remote control mode (inwhich a remote control indication exists on the display screen). In order to exit the remote control mode, click Local on the front panel toshift the signal generator from the remote control state to the local control state.

8.2.Rework Method

If it is confirmed via communications that rework of an instrument is required, use the original packaging materials and boxes to pack it,with the following steps followed:

a) Prepare a detailed document covering faults and error messages of the faulty instrument, or place the instrument together with a

120

copy of the instrument test report into the package.

b) Use the original packaging materials to pack the instrument properly to minimize damage.

c) Set pads correctly at four corners of an outer carton box and then place the instrument into the box.

d) Use adhesive tapes to seal the packaging box openings properly and then wrap nylon tapes for reinforcement.

e) Mark "Fragile! No touch! Handle with care! on the box body.

f) Arrange consignment of the precise instrument.

g) Keep copies of all transport documents.

Use of other materials for packaging may cause damage to the instrument. It is prohibited to use the polystyrene spheres as thepackaging materials, because they cannot protect the instrument effectively and may be sucked into the instrument fans due to staticelectricity produced, which will consequentially damage the instrument.
