MEASUREMENTS

Function: The 5400 Series measures swept freq-

uency transmission, reflection and power charac-teristics of microwave devices using a built-in micro-

wave source along with external detectors and/orSWR Autotesters.

Measurement Modes: Transmission (dB), ReturnLoss (dB), SWR (linear SWR), and Power (dBm).

Frequency Range: Eleven models cover the range

1.0 MHz to 26.5 GHz, determined by range of thesignal source of the particular model (Table 1-5). Meas-

urement range also determined by WILTRON 5400 Se-ries or 560 Series SWR Autotester and/or Detector used

with Analyzer portion of unit.

ANALYZER

Inputs: Two inputs standard (A and B); third input (R)

is optional. Inputs accept detected outputs from WIL-TRON 5400 Series or 560 Series SWR Autotesters and

Detectors. Third input adds A/R and B/R input ratio

capability. Measurements can be made in waveguideusing suitable waveguide detectors and a WILTRON

560-10BX-1 Adapter Cable.

Dynamic Range: 71 dB (55 dBm to +16 dBm) for all

channels, usable to 60 dBm.

Data Correction:System residuals, including the av-

erage of open and short reflections, are stored during

calibration and automatically subtracted from test data.

Calibration: During the calibration sequence, the

number of data points used for each trace are storedwith 0.002 dB resolution over any user-selected fre-

quency range. Calibration data are automatically interpo-lated for ranges less than the original normalized range.

Trace Memory: For both channels: the data for any

measurement trace, or high/low active limit line, maybe stored to active trace memory. This memory data

may be recalled later for viewing or output or may besubtracted from any subsequent measurement.

Save/Recall:Nine front-panel setups can be stored forlater recall; four of these may include calibration data.

Stored setups may be displayed/printed before selec-tion. Four sets of trace memory data for each channelcan also be stored. This data can be recalled to active

trace memory to be viewed, etc (see above).

Analyzer Accuracy Summary: Refer to Tables 1-3and 1-4.

DISPLAY

Display Channels: Select and display one or any twosignals from A, or B inputs, or (optional) R input. These

signals can also be displayed as ratios of A/R or B/R.

Alternate Sweep: Displays alternate sweeps be-tween the current frequency sweep and an alternate

sweep.

Display Resolution:

Horizontal:51, 101, 201, or 401 points per trace over

the selected frequency range.Vertical: 0.025 dB

Trace Update Time: Varies with frequency range, av-

eraging/smoothing settings, and number of data points

selected. Typically


10/100

MARKERS AND CURSORS

Markers: Up to eight individually controlled markers,

can be placed on the display. Amplitude readout of bothtraces at each marker is displayed in dB, dBm, or

SWR. Frequency resolution of markers is 10 kHz formodels 5407A, 5409A and 5411A and 100 kHz for all

other models.

Cursor: Position is selectable via tuning knob. Thefrequency and amplitude of the test data at the cursor

is displayed for both traces when cursor in on.

Relative Cursor: Displays the frequency and ampli-tude difference between the Main Cursor and Refer-

ence Cursor for both traces. A menu selection reversesthe position of the two cursors.

Cursor Min/Max: Moves the cursor to the minimum

or maximum point on the trace as selected.

Cursor X dB:Moves cursor to X dB value on theselected trace.

Cursor X dB Bandwidth:Moves both main Cursor

and Reference Cursors to the first X dB value to the leftand to the right of the initial reference position.

Cursor Next Marker: Moves cursor directly to nexthighest frequency marker.

Source

Frequency Range: 1.0 MHz to 26.5 GHz in ten mod-els.

Start-Stop:Sweeps upward from Start Frequency to

Stop Frequency. Start frequency must be less thanstop frequency.

Center-Width: Sweeps frequency upward from

CENTER (WIDTH/2) to CENTER + (WIDTH/2).

Alternate Sweep: Sweeps alternately between

frequency ranges set differently for Channels 1 and 2.

CW: Source output is a single frequency (f = StartFrequency) when both display channels are turned off.

Start Frequency Accuracy: 100 kHz for models5407A, 5409A and 5411A and 200 kHz for all othermodels.

Output Power: Depends on model, see Table 1-5.

Power Level Control, Internally Leveled: Front

panel control adjusts power over a 10 dB range (stand-

ard) or from 70.0 dBm to maximum leveled powerwhen Option 2, 2A, or Option 2B 70 dB Step

Attenuator is installed (paragraph 1-6).

External Leveling (Option 6): When used withexternal microwave detector, source output power is

maintained at constant level by detector output signal(refer to paragraph 1-6). Detector connects to rear

panel EXTERNAL LEVELING connector and must pro-

vide a positive or negative polarity detected signal of

30 to 200 mV.

Power Level Control With External Leveling(Option 6): Front panel control adjusts power over a10 dB range determined by external leveling detector

output.

Attenuator: Optional 70 dB Step Attenuator with10 dB steps: Option 2 (models 5407A, 5409A and

5411A), 2A (models with upper band edge 20 GHz),or 2B (model 5436A).

Markers: The numerical amplitude of the test data and

frequency are displayed for both channels. The fre-quency is continuously variable with the keypad or

tuning knob over the entire instrument frequencyrange. Markers remain fixed at the set frequency, inde-

pendent of sweep frequency range.

Horizontal Output: Rear panel BNC connector,

0 to +10V ramp coincident with sweep in all sweepmodes.

Output Connector Type: All models except 5436A

equipped with type N female connector, with 50out-put standard. Option 4 provides 75output for models5407A, 5409A, and 5411A. Model 5436A equipped with

1-10 PRECAUTIONS FOR USE OF SWRAUTOTESTERS AND RF DETECTORS

The 560 Series SWR Autotesters and RF Detectors

are high-quality, precision laboratory devices that

conta in G eneral P recision class Connectors (GP Cs).

Follow the precautions listed below when handlingor connecting these devices. Complying with these

precautions will guarantee longer component life

and less equipment downtime due to connector or

device failure. Su ch compliance will ensure th a t RF

component failures are not due to misuse or abuse

(th ese tw o fa ilure ca uses not covered under t he WIL-

TRON warranty).

a . B ewa r e of d est r u c t i v e P i n Dep t h of Ma t i n g

Connec to r s

Based on RF components returned for repair,

destructive pin depth of ma ting connectors is t he

ma jor ca use of failure in th e field. When a n RF

component connector is ma ted w ith a connector

ha ving a destructive pin depth, da ma ge will usu-

ally occur to the RF component connector. A de-

structive pin depth is one that is too long in

respect to the reference plane of the connector

(Figure 1-2).

The center pin of a precision RF component con-

nector has a precision tolerance measured in

mil s (1/1000 inch ). The m a t ing connect ors of

various RF components may not be precision

types. Consequently, t he center pins of these de-

vices may not have the proper depth. The pindepth of DUT connectors should be measured to

assure compatibility before attempting to mate

them with SWR Autotester or detector connec-

tors. A WILTRON P in D epth G a uge (Figure 1-3),

or equivalent, can be used for t his purpose. I f the

measured connector is out of tolerance in the

+ region, th e center pin is t oo long (see Ta ble

1-10). Mating under this condition will probablydamage the precision RF component connector.

If the test device connector measures out of tol-

erance in the region, the center pin is too

short. This will not cause damage, but it will

result in a poor connection and a consequent

degradation in performance.

b . A voi d O ver -T o r q u i n g C on n ec tor s

Over-torquing connectors is destructive; it may

damage the connector center pin. Always use a

connector torque wrench (8 inch-pounds) when

tightening GPC-7, WSMA, and K type connec-

tors. (Finger-tight is usually sufficient for TypeN connectors) . N ever use p l ie rs to t i gh t en

connectors.

c. A voi d M ech a n i ca l S h ock

Do not drop or otherwise treat RF components

roughly. These devices ar e designed to w ith st a nd

years of normal bench handling. However, me-

chanical shock will significantly reduce their

service life.

Series 560-7XXX Detectors a re ra ted a t + 20 dB m

maximum input power. Exceeding these input

power levels, even for short durations, can per-

manently damage the internal components of

th ese devices.

e. N o t D i s t u r b Tef l o n Tu n i n g Wa sh er s O n

Connecto r Cen t er P i ns

The center conductor of many RF component

connectors conta ins a s ma ll teflon tun ing wa sher

that located near the point of mating (Figure

1-7). This w a sher compensa tes for m inor imped-

a nce discontinuities at the int erface. Do not di s-

tu rb thi s washer. The location of this washer is

critical to the performance of the component.

f . C ompen sa t i o n Wa sh er s (WSMA Con n e ct or s )

WSMA connectors are optimized for connection

to standard SMA connectors . Whenever two

WSMA connectors a re ma ted, a beryllium copper

c o m p e n s a t i o n w a s h e r s h o u l d b e i n s e r t e d

between the two connectors near the point of

mating (to provide optimum mating depth for

th is connector combinat ion). The only exceptions

a re: th e WSMA Open/Sh ort, an d the RF Output

connectors of the 54XXA and other WILTRON

RF signal sources. Figure 1-5 shows a typical

compensation washer installation.

g . K eep Con n e ct o r s C l ea n

The precise geometry that makes possible the

RF components high performance can be easilydisturbed by dir t and other contamination ad-

hering to connector interfaces. When not in use,

keep the connectors covered.

To clean th e connector int erfaces, use a clean

cotton swab t hat has been dampenedw i th denat-

ured alcohol . Proper techniques for cleaning

GPC type connectors are as follows.

Always use denatured alcohol as cleaningsolvent. Never use industria l solvent or w at er,

as damage to the connectors may result.

U se only a sma ll amount of alcohol; otherw ise,prolonged drying of the connector may be

required.

Never put lateral pressure on the center pinof the connector.

Verify tha t no cotton or other foreign ma terialremains in th e connector a fter clea ning it .

If a va ilable, use compressed air t o remove for-eign part icles an d t o dry t he connector.

After cleaning, verify that the center pin hasnot been bent or damaged.

NOTE

Most cott on swa bs ar e too large to fit

into the smaller connector types. In

these cases it is necessary to peel off

most of the cotton a nd then tw ist the

remaining cotton t ight . Be sure that

the remaining cotton does not get

stuck in the connector.

SECTION IIINSTALLATION

2-1 INTRODUCTIONThis section provides information for the initial in-

spection and preparation for use of the 54XXA Sca-

lar Measurement System. Information for interfac-

ing the 54XXA to the IEEE-488 General Purpose

Interface Bus a nd reshipment a nd storage informa-

tion is also included.

2-2 INITIAL INSPECTION

Inspect the shipping container for damage. If the

conta iner or cushioning ma terial is dam a ged, reta in

until the contents of the shipment have beenchecked aga inst t he packing list an d the instr ument

has been checked for mechanical and electrical op-

eration.

If t he 54XXA is dama ged mecha nica lly, notify your

local sales representative or WILTRON Customer

Service. I f either t he shipping cont ainer is da ma ged

or the cushioning material shows signs of stress,

notify the carrier as well as WILTRON. Keep the

shipping m a terials for t he carriers inspection.

2-3 PREPARATION FOR USE

Preparation for use consists of checking that the

rear panel line voltage module is set for the correct

line voltage. The voltage selector drum of this mod-

ule may be set for either 115 or 230 Vac operation;

see Figure 2-1. If the selector drum setting is incor-

rect for the line voltage available, set it to the cor-

rect setting and insert the correct line fuse as

shown in t he chart in Figure 2-1.

2-4 GPIB SETUP ANDINTERCONNECTION

If equipped with Option 03, all functions of the

54XXA (except pow er on/off) ca n be cont rolled r e-

motely by a n externa l computer/cont roller via th e

IEEE-488 GPIB. The information in this section

perta ins t o interface connections a nd cable require-

ments for the rear panel GPIB connector. Refer to

the GPIB Users Guide (located behind the Supple-

ment s/Options t a b) for informa tion a bout remote

operat ion of the 54XXA using th e GP IB .

The 54XXA GP IB cont roller operat es with a ny IB M

XT, AT, or P S /2 compa t ible compu t er/cont roller

equipped with a National Instruments GPIB-

P CII /IIA interface card a nd NI -488 MS-DOS Ha n-

dler Software. The procedures for installing this

hardware and software in your computer is con-

ta ined in Appendix B a t the rear of this ma nual .

2-4.1 Interface Connector

Interface between the 54XXA and other devices onthe GPIB is via a s tandard 24-wire GPIB interface

cable. This cable uses a double-sided connect or; one

connector face is a plug, the other a receptacle.

These double-function connectors a llow pa ra llel con-

nection of tw o or more cables t o a single instr ument

connector. The pin assignments for the rear panel

G P IB connector are sh own in Figure A-3, locat ed in

th e Appendix.

2-4.2 Cable Length Restrictions

The GP IB system can a ccommodat e up to 15 inst ru-

ments a t a ny one time. To achieve design perform-

ance on the bus, proper timing and voltage level

relationships must be maintained. If either the ca-

ble length between separate instruments or the ac-

cumulated cable length between all instruments is

too long, th e dat a an d contr ol lines ca nnot be driven

properly and the system may fail to perform. Cable

length restr ictions a re as follows :

No more than 15 instruments may be installedon the bus.

Total accumulative cable length in meters maynot exceed two times the number of bus instru-

2-4.3 System GPIB Interconnection

The rear panel GPIB IEEE-488 connector is used tointerface the 54XXA to an external computer/

controller (or plotter) via a standard GPIB cable.

The WILTRON Part numbers for s tandard GPIB

cables of various lengths a re listed in Section I .

2-4.4 GPIB Interface to an External Plotter

If equipped w ith Opt ion 03, the 54XXA GP IB inter-

face can be configured to contr ol a suit able externa l

plotter (refer to Table 1-2 and to Section IIIFront

Panel Operation). In this mode of operation, the

GPIB is dedicated to this applicat ion and only the

54XXA and the plotter are connected to the GPIB.

Standard GPIB cables are used to interconnect to

the plotter.

2-4.5 GPIB Addresses

The 54XXA leaves the factory with the default

GPIB address se t to 6 and the exte rna l p lo t te r

interface default address se t to 8 . These ad-

dresses may be cha nged using th e menus invoked

by the f ront pan e l SYSTEM MENU key. This pro-

cedure is explained in Section I I I .

2-5 EXTERNAL MONITOR CONNECTOR

The rear panel EXTERNAL MONITOR connector

allows the internal display information of the54XXA to be connected to a n ext erna l VGA monitor

(either color or monochrome). The pinout of this

15-pin Type D connector is shown in Figure A-2,

located in the Appendix.

2-6 PREPARATION FOR STORAGEAND/OR SHIPMENT

The following pa ra gra phs describe th e procedure for

preparing the 54XXA for storage or shipment.

2-6.1 Preparation for Storage

Preparing the 54XXA for storage consists of clean-

ing the unit, packing the inside with moisture-ab-

sorbing desiccant crystals, and storing the unit in a

temperature environment that is maintained

between 4 0 and + 70 degrees centigrad e (40 to

156 degrees Fahrenheit).

2-6.2 Preparation for Shipment

To provide maximum protection a ga inst da ma ge in

transit, the 54XXA should be repackaged in the

original shipping container. I f this container is no

longer a vaila ble and t he 54XXA is being returned t o

WILTRON for repair, advise WILTRON CustomerService; they will send a new shipping container

free of charge. In the event neither of these two

options is possible, instructions for packaging and

shipment a re given below .

a . U se a Su i t a b l e C on t a i n er

Obtain a corrugated cardboard carton with a

275-pound test strength. This carton should

have inside dimensions of no less than six

inches larger than the instrument dimensions

to allow for cushioning.

b. P r ot ect t h e I n st r u m en t

Surround the instrument with polyethylene

sheeting to protect the finish.

c. Cu sh i on t h e I n st r u m en t

Cushion the instrument on all sides by tightly

packing dunnage or urethane foam between the

carton and the instrument. Provide at least

three inches of dunnage on all sides.

d . Sea l t h e C on t a i n er

Sea l the cart on by using either shipping ta pe or

an industrial s tapler .

e. A d d r ess t h e C on t a i n er

If the instrument is being returned to WIL-

TRON for service, mark the WILTRON address

an d your return a ddress on th e car ton in one or

more prominent locations. For international

customers, use the address of your local repre-

sent a tive (Ta ble 2-1). For U .S.A. cust omers, use

this input is processed and displayed in the same

manner as for the INPUT A signal, according to the

setup menu selections chosen by the user. The soft-

wa re default mea surement mode display s the B In-

put signal as a reflection type measurement dis-

played on Channel 2.

3-8.9 INPUT RConnector

The th ird (optiona l) input signa l connector is similar

to inputs A and B. I t can be used for ratio type

measur ements, w here the processed INPUT Rs ignali s l o g a r i t h m i c a l l y s u b t r a c t e d f r o m e i t h e r t h e

measurement functions are set up via menu selec-

tion.

NOTE

The input signals applied to the front

panel input connectors are typically out-

put signa ls from S WR Autotesters an d de-

tectors. These signals are low-level, low-

frequency signals with dc components .Refer to Section IV Measurement and

Calibrat ion Procedures for information

about typical measurement se tups and

usage .

3-9 DATA ENTRY KEY GROUP

The DATA ENTRY keys and data entry knob (Fig-ure 3-4) ar e used to enter da ta into th e setup menu

selections. The units associated with the entered

data are determined by the menu displayed during

entry a nd by the model: levels in dB (or dBr ) for a ll

models, frequency in MHz for models 5407A, 5409A

and 5411A, and in GHz for all other models. Units

are not entered with data .

3-9.1 Data Entry Keypad

This keypad consists of keys 09, . and . These

keys are used with the setup menus to enter re-

quired operational parameters.

3-9.2 Data Entry Knob

Changes the values of an act ive parameter during

menu entr y (cursor posit ion, offset, r esolut ion, etc.).

Fast knob movement changes the data in large in-

crements, slow m ovement a llow s fine cha nges to be

made.

3-9.3 ENTERKey

Terminat es th e da ta entry sequence. When pressed,

Service type cal ibrat ion procedures aredescribed in the 54XXA Scalar Measure-

ment System Maintenan ce Man ual .

3-10.7 UNCALIndicator

This LED indicator is lit when either measurement

chann el requires re-calibrat ion. This is u sua lly due

to a significant change of the front panel control

settings for t he signal source or either mea surement

channel.

This key group consists of the keys and indicator

LEDs shown in Figure 3-7. The menus associated

with these keys are shown in Figure 3-19 (located

behind Operating Menus tab).

The two operating modes of the 54XXA internal

signal s ource ar e:

Normal Mode w hen eith er measurement cha n-nel is turned on.

CW Mode when both measurement channelsare turned off. The source operating frequency inthis mode is either the START frequency, or, for

CENTER/WIDTHmode:

Frequency = CENTER freq 1/2 WIDTH freq.
