1-4 DESCRIPTION OF 54XXA SYSTEM

The 54XXA is a microprocessor controlled scalar
measurement syst em. This system is used to make
scalar (magnitude) transmission, reflection, and ab­solute power measurements. A typical model is
shown in Figure 1-1 (facing page). All measurement
functions are selectable by using the front panel
keys and controls together wi th the display screen
menus. Section III describes this mode of operation.

All 54XXA front panel control functions (except
POWER on/off) are programmable via the I EEE–488
interface bus (GPIB). This function can be ordered
as an option on all models (refer t o paragraph 1-6).
Remote operation of the 54XXA using GPIB com­mands is described in the GPIB User’s Guide for the
54XXA Series Scalar Measurement Systems that is
located behind the Supplements/Options tab at the
rear of this manual.

The measurement frequency range of the 54XXA is
determined by:

The range of the internal signal source of the

•

particular model.
The external SWR Autotester and/or detector

•

used with the 54XXA.

MEASUREMENTS

Function: The 5400 Series measures swept freq-

uency transmission, reflection and power charac­teristics of microwave devices usin g a built-in micro­wave source along with external detectors and/or
SWR Autotesters.

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

Frequency Range: Eleven mo dels cover the range

1.0 MHz to 26.5 GHz, determined by range of the
signal source of the particular model (T able 1-5). Meas­urement range also determined by WILTRON 5400 Se­ries or 560 Series SWR Autotester and/or Detector used
with Analyzer portion of unit.

ANALYZER

Inputs: Two inputs standard ( A and B); th ir d inpu t ( R )

is optional. Inputs accept dete cted outputs from WIL­TRON 5400 Series or 560 Series SWR Aut otesters and
Detectors. Third input adds A/R and B/R input ratio
capability. Measurements can be made in waveguide
using 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 av­erage of open an d short reflec tions, are st ored during
calibration and automatically subtracted from test data.

Calibration: During the calibration sequence, the
number of data points used for each trace are stored
with 0.002 dB resolution over any user-selected fre­quency range. Calibration data are automatically interpo­late d for rang es less than the original normalized range.

Trace Memory: For both channe ls: the data for any
measuremen t trace, or high/low ac tive limit line, may
be stored to active trace memory. This memory data
may be rec alled later fo r viewing or outp ut or may be
subtracted from any subsequent measurement.

Save/Recall: Ni ne fro nt- pane l se tups can be store d fo r
later recall; four of these may include calibration data.
Stored setups may be di splayed/pri nted before selec­tion. Four sets of trace memory data
can also be stored. This data can be recalled to active
trace memory to be viewed, etc (see above).

1-1.2 Detectors

The 5400 Series and 560 Series Detectors are used
for coaxial transmission loss or gain and power
measurements. Zero-biased Schottky diodes provide

a measurement range of –55 dBm to +16 dBm. Field
replacement of the detector diode is possible with the
5400-71B75 detector and most of the 560-7 Series
RF Detectors Tables 1-8 and 1-9). Optional extender
cables can be used without degradation in perform­ance. With suitable coaxial adapters they may be
used for waveguide reflectometer measurements.
The precaution s for using these component are de­scribed in paragraph 1-10.

PRECAUTIONS FOR USE OF

I GENERAL INFORMATION AUTOTESTERS AND RF DETECTORS

1-10 PRECAUTIONS FOR USE OF SWR

AUTOTESTERS AND RF DETECTORS

The 560 Series SWR Autotesters and RF Detectors
are high-quality, precision laboratory devices that

contain General Precision class Connectors (GPC’s).
Follow the precautions listed below when handling
or connecting these devices. Complying with these
precautions will guarantee longer component life
and less equipment downtime due to connector or
device failure. Such compliance will ensure that RF
component failures are not due to misuse or abuse
(these two failure causes not covered under the WIL­TRON warranty).

a. Bewa re of destructive Pin Depth of Mating

Connectors

Based on RF components returned for repair,
destructive pin dept h of mating conn ectors is t he
major cause of failure in the field. When an RF
component connector is mated with a connector
having a destructive pin depth, damage will usu­ally occur to the RF component connector. A de­structive 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 pr ec isio n R F co m po nent c on ­nector has a precision tolerance measured in
mils (1/1000 inch). The mating connectors of
various RF components may not be precision
types. Consequently, the center pins of these de­vices may not have the proper depth. The pin
depth of DUT connectors should be measured to
assure compatibility before attempting to mate

“+” region, the center pin is too long (see Table
1-10). Mating under this condition will probably
damage the precision RF component connector.
If the test device connector measures out of tol­erance 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. Avoid Over-Torquing Connectors

Over-torquing connectors is destructive; it may
damage the connector cente r pin. Always use a
connector torque wrench (8 inch-pounds) when
tightening GPC-7, WSMA, and K type connec­tors. (Finger-tight is usually sufficient for Type
N connectors). Never use pliers to tighten

connectors.

PRECAUTIONS FOR USE OF
AUTOTESTERS AND RF DETECTORS I GENERAL INFORMATION

c. Avoid Mechanical Shock

Do not drop or otherwise treat RF components
roughly. These devices are designed to withstand
years of normal bench handling. However, me­chanical shock will significantly reduce their
service life.

d. Avoid Applying Exces sive Power

Series 560-9XXXX SWR Autotesters are rated at
+27 dBm (0.5 W) maximum input power, and
Series 560-7XXX Detectors are rated at +20 dBm
maximum input power. Exceeding these input
power levels, even for short durations, can per­manently damage the internal components of
these devices.

e. Not Disturb Teflon Tuning Washers On

Connector Center Pins

The center conductor of many RF component
connectors contains a small teflon tuning washer
that located near the point of mating (Figure
1-7). This washer compensates for minor imped­ance discontinuities at the interface. Do not dis-
turb this wa sher. The location of this washer is
critical to the performance of the component.

connectors of the 54XXA and other WILTRON
RF signal sources. Figure 1-5 shows a typical
compensation washer installation.

g. Keep Connectors Clean

The precise geometry that makes possible the

RF component’s high performance can be easily
disturbed by dirt and other contamination ad­hering to connector interfaces. When not in use,
keep the connectors covered.

To clean the connector interfaces, use a clean
cotton swab that has been dampened with den at­ured alcohol. Proper techniques for cleaning
GPC type connectors are as follows.

• Always use denatured alcohol as cleaning
solvent. Never use industrial solvent or water ,
as damage to the connectors may result.

• Use only a small amount of alcohol; otherwise,
prolonged drying of the connector may be
required.

• Never put lateral pressure on the center pin
of the connector.

• Verify that no cotton or other foreign material
remains in the connector after cleaning it.

• If available, use compressed air to remove for­eign particles and to dry the connector.

• After cleaning, verify that the center pin has
not been bent or damaged.

NOTE

The teflon washer is shown on a GPC-7
connector. A similar washer may be installed
on any WILTRON precision connector.

Figure 1-4. Typical Tuning Washer Usage

f. Compensation Washers (WSMA Connectors)

WSMA connectors are optimized fo r connection
to standard SMA connectors. Whenever two
WSMA connectors are mated, a beryllium copper
compensation washer should be inserted
between the two connectors near the point of
mating (to provide optimum mating depth for
this connector combination). The only exceptions
are: the WSMA Open/Short, and the RF Output

NOTE

Most cotton swabs are too large to fit
into the smaller connector types. In
these cases it is nece ssary to peel off
most of the cotton and then twist the
remaining cotton tight. Be sure that
the remaining cotton does not get
stuck in the connector.

SECTION II

INSTALLATION

2-1 INTRODUCTION

This section provides information for the initial in­spection and preparation for use of the 54XXA Sca­lar Measurement System. Information for interfac­ing the 54XXA to the IEEE-488 General Purpose
Interface Bus and reshipment and storage informa­tion is also included.

2-2 INITIAL INSPECTION

Inspect the shipping container for damage. If the
container or cushioning material is damaged, retain
until the contents of the shipment have been
checked against the packing list and the instrument
has been checked for mechanical and electrical op­eration.

If the 54XXA is damaged mechanically, notify your
local sales representative or WILTRON Customer
Service. If either the shipping container is d amaged
or the cushioning material shows signs of stress,
notify the carrier as well as WILTRON. Keep the

shipping materials for the carrier’s inspection.

The 54XXA GPIB controller operates with any IBM
XT, AT, or PS/2 compatible computer/controller
equipped with a National Instruments GPIB­PCII/IIA interface card and NI-488 MS-DOS Han­dler Software. The procedures for installing this
hardware and software in your computer is con­tained in Appendix B at the rear of this manual.

2-4.1 Interface Connector

Interface between the 54XXA and other devices o n
the GPIB is via a standard 24-wire GPIB interface
cable. This cable uses a double-sided connector; one
connector face is a plug, the other a receptacle.
These double-function connectors allow parallel con­nection of two or more cables to a single instrument
connector. The pin assignments for the rear panel
GPIB connector are shown in Figure A-3, located in
the Appendix.

2-3 PREPARATION FOR USE

Preparation for use consists of checking that the
rear panel line voltage module is s et 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 incor­rect for the line voltage available, set it to the cor­rect setting and insert the correct line fuse as
shown in the chart in Figure 2-1.

2-4 GPIB SETUP AND

INTERCONNECTION

If equipped with Option 03, all functions of the
54XXA (except power on/off) can be controlled re­motely by an external computer/controller via the
IEEE-488 GPIB. The information in this section
pertains to interface connections and cable require­ments fo r the rear panel GPIB connector. Refer to
the GPIB Users Guide (located behind the Supple­ments/Options tab) for information about remote
operation of the 54XXA using the GPIB.

2-4.2 Cable Length Restrict io ns

The GPIB system can accommodate up to 15 instru­ments at any on e time. To achieve design pe rform­ance on the bus, proper timing and voltage level
relationships must be maintained. If either the ca­ble length between separate instruments or the ac­cumulated cable length between all instruments is
too long, the data and control lines cannot be driven
properly and the system may fail to perform. Cable
length restrictions are as follows:

• No more than 15 instruments may be installed
on the bus.

• Total accumulative cable length in meters may
not exceed two times the number of bus instru­ments or 20 meters—whichever is less.

NOTE

For low EMI applications, the GPIB cable
should be a fully shielded type, with well­grounded metal-shell connectors.

54XXA OM 2-3

PREPARATION FOR STORAGE AND/OR SHIPMENT II INSTALLATION

2-4.3 System GPIB Interconnection

The rear panel GPIB IEEE-488 co nnector is us ed to
interface the 54XXA to an external computer/
controller (or plotter) via a standard GPIB cable.
The WILTRON Part numbers for standard GPIB
cables of various lengths are list ed in Section I.

2-4.4 GPIB Interface to an External Plotter

If equipped with Option 03, the 54XXA GPIB inte r­face can be configured to control a suitable external

plotter (refer to Table 1-2 and to Sectio n III—Front
Panel Operation). In this mode of operation, the
GPIB is dedicated to this applicatio n 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 set to 6 and the external plotter
interface default address set to 8. These ad­dresses may be changed using the menus invoked
by the front panel SYSTEM MENU key. This pr o­cedure is explained in Section III.

2-5 EXTERNAL MONITOR CONNECTOR

The rear panel EXTERNAL MONITOR connector
allows the internal display information of the
54XXA to be connected to an external 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.

2-6.2 Preparation for Shipment

To provide maximum protection against damage in
transit, the 54XXA should be repackaged in the
original shipping container. If this container is no
longer available and the 54XXA is being returned to
WILTRON for repair, advise WILTRON Customer
Service; 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 are given below.

a. Use a Suitable Container

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. Protect the Instrument

Surround the instrument with polyethylene
sheeting to protect the finish.

c. Cushion the Instrument

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. Seal the Container

Seal the carton by using either shipping tape or
an industrial stapler.

2-6 PREPARATION FOR STORAGE

AND/OR SHIPMENT

The following paragraphs describe the procedure for
preparing the 54XXA for storage or shipment.

2-6.1 Preparation for Storage

Preparing the 54XXA for storage consis ts of clean­ing the unit, packing the inside with moisture-ab­sorbing desiccant crystals, and storing the unit in a
temperature environment that is maintained
between –40 and +70 degrees centigrade (–40 to
156 degrees Fahrenheit).

2-4 54XXA OM

e. Address the Contai ner

If the instrument is being returned to WIL­TRON for service, m ark the WIL TRON addr ess
and your return address on the carton in one or
more prominent locations. For international
customers, us e the address of your local repre­sentative (Table 2-1). For U.S.A. customers, use
the WILTRON address shown below:

The CRT screen di s pla y sh ow s mea su re men t re su l ts
and setup information. It also displays set up menus
that are used in conjunction with the front panel
control keys to control the instrument meas urement
parameters.

• Measurement Display and Annotation — The

measurement screen display (Figure 3-1)
includes one or two measurement traces, meas­urement function settings, cursors, markers,
limit lines, and the signal source frequency and
output power parameters. The measurement
traces are referred to as display channels 1 and

2. They are set up via the display channel
menus. If the signal source is programmed for
alternating frequency ranges, then trace 1 dis­plays the main setting and trace 2 displays the
alternative settings.

• Netwo rk Analyzer Settings — The tw o lines la-

beled “1:” and “2:” across the to p of the screen
display the type of measurement sele cted and
the offset and vertical resolution values for
traces 1, 2, or both. The input connector se­lected for each trace is also shown. The Net­work Analyzer menu selections control the ver­tical axis of the display.

• Model/Status Information — The box in the

top right side of the screen displays model num­ber and status information. Examples:

“ALTERNATE SWEEP” is displayed when an
alternate sweep setup has been selected;
“HOLD” is displayed when the instrument is in
the Hold mode.

• S ource F requenc y, Power And Horizo ntal Reso -

lution (graticule) Settings — The three lines
along the bottom of the screen display:

• Signal s ource start/stop f requencies

• Alt ernate sweep st art/stop freq uencies

• Horizontal resolution (Graticule values) of

the displayed traces

• Power output of the signal source

• Detec tor Offsets, if us ed

The 54XXA automatically selects the correct
horizontal resolution and graticule divisions
for optimum display of the selected frequency­sweep widt h. In t he alt ernate- setup mode,
the graticule is fixed at ten vertical and hori­zontal divisions. All frequencies are displayed
in MHz for models 5407 /5409/5411, and in
GHz for all other models. The Signal source
menu selections control the horizontal axis of
the display.

3-3 INITIAL 54XXA CONTROL SETTINGS

When turned on, the control settings for all 54XXA
functions are set to those in effect during the last
usage of the unit. These settings may be reset to the
factory-selected values by using the RESET selection
from the SYSTEM menu. The default settings are
listed in Table A-1 in the Appendix.

3-4 CONTROL KEY FUNCTIONAL

GROUPS

The front panel control keys and knobs are located
in the functional groups listed below and shown in
Figure 3-2 (page 3-6). With the exception of the DA TA
ENTRY group, each control k ey group is used to se t
the operation of a specific set of 54XXA functions.
(The DATA ENTRY keys and knob are used to enter
and modify data for many menu selections.) These
control key groups and associated menus are further
described in the remainder of this section.

3-4.1 Control Key Operation

Many of the fro nt panel control keys pr oduce setup
menus when pressed. These menus appear at the
right side of the screen display (Figure 3-1). Other
keys, such as AUTOSCALE, SELF TEST, etc.,
perform specific functions directly.

3-4.2 Setup Menu Operation

Setup menu items are selected by using the
MENU Up/Down key to position the cursor next to
the desired menu selection and pressing the SELECT
key. There are three types of menu selection items:

• Those that perform specific functions directly
when selected .

• Those that require data parameter entry before
the ENTER key is pressed.

• Those that produce submenus when selected.

Menu selections may be cancelled (before the ENTER
key is pres sed) by p ressing the CLEAR key.

NOTE

While reading this section, follow along
using the front panel controls and associ­ated menus. R efer to the figur es that de­scribe the menus in each group. The an­notation for these figures describe each
menu selection in detail.

3-5 POWER-ON SELF TEST AND FRONT

PANEL LED ERROR CODES

When the 54XXA is turned on, or the SELF TEST key
is depressed, the instrument undergoes a compre­hensive self test. If the self te st passe s, the message

“ALL TESTS PASSED” is displayed on the screen and
the “TRACE HOLD” LED flashes briefly.

If the self test fails, an error message is displayed
and one of the control panel LED indicators will
flash steadily . A different LED indicator will flash for
each specific type of fault. The LED indicator fault
detection codes are listed in Table A-2 in the Appen­dix. This coding makes it possible to locate a fault
even if the CRT or display circuitry has failed.

3-6 WARNING/ERROR MESSAGES

If an unusual condition is detected during instru­ment operation, a warning or error message will be
displayed in the lower corner of the screen display.
These warning/error messages are listed and de­scribed in Table A-3 (in the Appendix). Suggested
remedial action is included for each message.

3-7 REAR PANEL CONNECTORS

The locations of the 54XXA rear panel connectors are
shown in Figure A-1 (in the Appendix). The rear
panel contains the line voltage module, multi-pin
GPIB and printer connectors, and additional BNC
type input/output connectors. Setup of the line
voltage module and connection to the GPIB connec­tor are described in Section II. The characteristics of
the PARALLEL PRINTER INTERFACE, HORIZONTAL
OUTPUT, and optional EXTERNAL ALC INPUT con­nectors are also described in Figure A-1. The rear
panel also contains a Printer Switch Setting chart
(shown in Table A-5)
