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).

I GENERAL INFORMATIONSYSTEM RF COMPONENTS
1-1.2Detectors
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 INFORMATIONAUTOTESTERS AND RF DETECTORS
1-10PRECAUTIONS 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 DETECTORSI 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.

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.
2-2INITIAL 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.
2-4.1Interface 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.
2-3PREPARATION 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.
2-4GPIB 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.
2-4.2Cable 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.

PREPARATION FOR STORAGE AND/OR SHIPMENTII INSTALLATION
2-4.3System 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.
2-4.4GPIB 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.
2-4.5GPIB 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.
2-5EXTERNAL 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.
2-6.2Preparation 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.
2-6PREPARATION FOR STORAGE
AND/OR SHIPMENT
The following paragraphs describe the procedure for
preparing the 54XXA for storage or shipment.
2-6.1Preparation 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).
2-454XXA 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

through power-down and self-test.
3-12.1 SYSTEM MENU Key and Menus
d. Configure Analyzer – Displays a submenu
Displays the menu shown in Figure 3-20. Submenus
from this menu perform the following functions:
that allows control of the following functions of
the network analyzer portion of the 54X XA:
• Reset the 54XXA to factory -selected initial front
panel control settings.
• S et the configuration of the frequency source and
network analyzer portions of the 54XXA.
• S elect testing modes f or different applications.
The submenus selected from the main menu enable
the user to control the system configuration and
measurement functions listed below:
a. M easurement Data Points – Sets the num-
ber of measurement Data Points to 51, 101, 201,
or 401. (This also sets the number of frequencies
output by the internal signal source for each
measurement trace.)
b. Controls Reset Function – Resets the 54XXA
front panel control settings to factory-selected
values. Previously saved Calibration, Frequency
Marker and Limits data may be selectively retained through the reset function via selections
from the RESET submenu (Figure 3-20).
This reset function does not clear any detector
offsets in effect. To clear detector offsets, press

the required compression level.
• Select titling and labeling functions. These
utility functions allow the measurement
display titles and labeling to be changed.
• Control the color attributes of an external
VGA monitor (if used). The attributes of the
display Text, Channel 1/C hannel 2 traces,

• Set up and invoke the Frequency Scaling
function. This function causes the 54XXA to
display operating frequency values that are
“scaled” from those actually output by the
frequency source (see example below). These
scaled values are also us ed for hard copy output. The relationship between the actual output frequency (Int Freq) and that displayed
(User Freq) is as follows:

models 5407A/ 5409A/5411A
and ±99.9999 GHz for all
other models.
EXAMPLE:
m = 10, d = 2, and f = 40 will cause
model 5428A to display 80 to 102 GHz
with a true output of 8 to 12.4 GHz.
• Set Autozero function on or off. The OFF se-
lection holds the autozero circuit correction
voltage of each active measurement channel
at the current value and causes the frequency
source output to be on continuously . This function is useful for testing devices that require
continuous stimulus during test.
3-12.2 SAVE/RECALL Key and Menus
Displays the main SAVE/RECALL menu shown in
Figure 3-21. Submenus from this menu control the
trace memory/setup data store/retrieve functions
listed below . All memory storage locations associated
with the SAVE/RECALL key are non-volatile mem-
ory. Data stored in these locations is saved throughout power-down and st artup cycl es.
• S ave or recall up to nine front panel setups to or
from memory locations 1 through 9.
• Save or recall a calibration setup and associated
measurement dat a to or from trace memo ry storage locations 1 through 4.
• Set up titles for the saved setup/calibration data
that may include date and identification information. This allows the saved setups to be recalled
by title.
• P review s aved calibration and/or se tup data prior
to use.
• Save or recall up to four sets of trace memory data
for each display channel (Figure 3-6, page 3-9).
The saved measurement trace data may include
simple or complex limit line information.
NOTE
There are two additional “active”
trace memories that are accessed via
the menus from the (NETWORK ANA-LYZER) MENU key. Refer to paragraph 3-10 and Figure 3-6.
• Configure SAVE/ RECALL key for “Single Button
Recall” mode of operation (Figure 3-21). Once
this operating mode has been set up, any previously-saved front panel setup (or calibration/front panel setup, or trace memory data
store) can be recalled by pressing the SAVE/ RE-CALL key and the keypad number that corresponds to the desired setup.
All other front panel functions (cursor readout,
data entry, etc.) perform normally while this operating mode is active, and all front panel functions are usable with any recalled setup. (Single
Button Recall is temporarily suspended until the
regular front panel operation is completed.)
The “RECALL ONL Y MODE” message is displayed
in the System Status Display box in the upper
right portion of the screen wh enever this operat ing mode is active. This o perating mode remains
active until cancelled. It can be cancelled by using
the SAVE / R ECALL MODE selection from the Re-
call Mode Setup menu or by using the RESET
menu selection from the SYSTEM menu.

4-2OPERATIONAL CHECKOUT
PROCEDURE
The 54XXA Scalar Measurement System undergoes
a comprehensive self test when turned on, or when
the SELF TEST key is pressed. The “ALL TESTSPASSED” message that displays on the screen at the
conclusion of the self test signifies t hat all internal
control circuits are operating properly.
To perform a simple operational check that confirms
that the frequency source and network analyzer circuits are functioning, follow the procedure outlined
in Table 4-1.
4-3CALIBRATION PROCEDURE
Before the 54XXA is used for a transmission or reflection measurement, a test setup normalization
procedure must be performed. This procedure is re-
ferred to as “calibration.” Calibration is the process
whereby losses inherent in a transmission or return
loss measurement system are measured, stored in
internal memory, and later subtracted from the test
measurement data. As a result, subsequent screen
displays (and test data) reflect the characteristics of
the test device only.
NOTE
A calibration is not required before using
the 54XXA to perform power measurements.
When the CALIBRATION key is presse d, a series of
menus/instructions are displayed that guide the
user through the calibration procedure. The calibration procedure should be performed using the same
test set up (with the device -under -test re moved) that
will be used for the actual test. This includes using
the same power level and measurement frequencies
as for the actual test. A typical setup for transmission and return loss measurements (and calibration)
is shown in Figure 4-1.
4-3.1Calibration Menu
The main calibration menu has three selections:
a. START CAL — This selection disp lays the in-
structions / m enus for the normal calibration sequence for transmission and reflection measurements (Table 4-2).
b. DETECTOR OFFSE TS — This selection al-
lows an offset (express ed in dB) to be specified
for any detector use d with th e A, B, or R inputs.
These values remain in memory, ev en after the
54XXA is powered down. The offsets can be
cleared by reselecting DETECTOR OFFSETS
and entering “0 dB.” Whenever one or more detector offsets are use d, a status message is displayed at the bottom of the screen. Example:
“DET OFS ABR” indicates that non-zero offsets
have been entered for each of the three inputs.
c. DC CAL MENU — This selection is used in
conjunction with the POWER selection from theNETWORK ANALYZER menus for Channel 1
and/or Channel 2 to perform absolute power
measurements. Refer to Table 4-6 (page 4-14).
4-4MEASUREMENT PROCEDURES
The 54XXA Scalar Measurement System can be used
to make transmission loss or gain, return loss, absolute power, and SWR measurements. Any of these
measurements can be set up using feat ures such as
alternate sweep frequency ranges, and/or trace
memory subtraction.
4-4.1Transmission and Return Loss
Measurements
The procedure for making transmission and return
loss measurements is described in Table 4-3 on
page 4-7. A screen display for a typical application is
54XXA OM4-3
Page 56
OPERATIONAL CHECKOUT PROCEDUREIV MEASUREMENT AND CALIBRATION PROCEDURES
shown in the table. The typical equipment setup for
these types of measurements is shown in Figure 4-1.
4-4.2Alter nate S weep Me asurem ents
The procedur e fo r mak ing al ter na te sw ee p mea surements is described in Table 4-4 (page 4-10). The
equipment setup for this type of measurement is
generally the same as for transmission and return
loss measurements. In this mode, the second (alternate setup) sweep parameters are set differently
from the regular sweep — usually with a reduced
frequency s pan. (This produces an expanded measurement display for the second sweep.) The alternate sweep mode is controlled via the menus associated with the ALTERNATE SWEEP key.
4-4.3Ratio Mode Measurements
Ratio-mode measurements arithmetically subtract
the R input from e ither the A or B input. This type
of measurement is set up by using the NETWORKANALYZER channel setup menus for Channel 1
and/or Channel 2. The procedur e for making these
measurements is described in Table 4-5 (page 4-12).
A typical equipment setup for this measurement is
shown in Figure 4-3.
The ratio measurement mode has many uses. It can
be used to compensate for the effects of a long signal
transmission path, such as where the device-under-
test (DUT) is located remotely from the 54XXA
system. Using extender cables between the
Autotester (and/or detector) and the 54XXA, it is
possible to locate the DUT up to 200 feet from the
54XXA (refer to Section I). Ratio mode can also be
used to maintain system calibration when the RFOUTPUT level is changed during the test.
4-4.4Absolute Power Measurements
The procedure f or making absolut e power measure ments is described in Table 4-6 (page 4-14) . A typical
equipment setup for this measurement type is
shown in the diagram included in the table.

SIGNAL CHANNEL VERIFICATION TESTSV PERFORMANCE VERIFICATION PROCEDURES
5-7SIGNAL CHANNEL VERIFICATION
TESTS
The signal channel verification is made up of three
individual parts:
Part 1 is a DC voltage calibration method test where
a known DC voltage is injected into the input of the
54XXA (paragraph 5-7.1).
Part 2 is a 50 MHz RF verification test using the
Anritsu power meter 50 MHz, 0dBm power reference
as a standard (paragraph 5-7.2).
Part 3 is a mid band frequency test that uses a
known RF input (paragraph 5-7.3). This test is susceptible to various measurement uncertainties,
which are explained in paragraph 5-7.4.
5-7.1DC Voltage Method
The DC voltage method uses highly accurate DC
voltages to simulate input RF power inputs. This
test introduces fewest source errors. A 560-10BX
adaptor cable is used to connect the output of the DC
Voltage St andard to the input of the 54XXA.
5. Press the CALIBRATION key and select “DCCAL MENU”.
6. Allow the 54XXA to sweep for 5 seconds.
7. With the SET DC MENU displayed, move the
highlighted cursor to “ON” and press SE-LECT. The 54XXA should display a noise floor
on Channel 1 in power mode with “DC CAL”
displayed in the to p right hand corner of the
screen display.
8. Set the voltage standard output to the first
value listed in Table 5-3a (page 5-15).
9. Press the CURSOR key to obtain a cursor
readout on the 54XXA display. Verify that the
cursor readout value is within the tolerance
specified in Table 5-3a. Record the readout
value in the table.

5-7.250MHz Accuracy Test
This test confirms the performance of the 54XXA at
50 MHz using 0 dBm and –30 dBm reference signals.
NOTE
If the 54XXA being tested is a model
5407A, 5409A, 5411A, 5417A, or 5447A,
this test need not be performed; go to
paragraph 5-7.3 (Mid Band Frequency
RF Test).
The 50 MHz calibration output of the Anritsu power
meter is used as the 0 dBm reference signal for this
test. This same reference signal is used in conjunction with the 30 dB attenuator from the Anritsu
MA4702A power sensor to produce the –30 dBm
reference signal. The measurement performance of
the 54XXA at 50 MHz can thus be confirmed at these
two levels.
During the test, the 54XXA is set to the “DC CAL”
mode to measure the fixed power output of the power
meter; this mode enables the 54XXA to make accurate power measurements by disabling the auto zero
function of each s ignal channel (refer to Sect ion IV,
Table 4-6).

RESIDUAL FM TESTV PERFORMANCE VERIFICATION PROCEDURES
d. Detector Frequency Response
The frequency response of the 560-7 series detector
introduces a possible measureme nt error, as shown
in Figure 5-8. This type of error is normally removed when a calibration is performed.
5-8RESIDUAL FM TEST
This test verifies that the residual FM of the 54XXA
signal source is within specified limits. The s pecification for this characteristic is different for the various 54XXA models. The residual FM specification for
each model type is listed in Table 1-5 in the General
Information section of the manual.
The residual FM measurement is made at the highest signal source output frequency for the particular
54XXA model, as this is the frequency at which the
residual FM is maximum. The Anritsu MS2802 spectrum analyzer is used to down convert the 54XXA
signal source output so that the Marconi TF2304
Modulation meter can be used to measure the FM
products.

and turn the equipment on.
2. Press the SYSTEM MENU key and select “RE-SET” using the MENU up/down and SELECT
keys. From the RESET MENU select “RE-STORE DEFAULT SETUP”.
3. Turn both measurement channels off using
the DISPLAY ON/OFF keys. Press theOUTPUT POWER key and set the power to
+4.0 dBm (+7 dBm for units without an internal step attenuator).
4. Press the FREQUENCY key and set the
START frequency to the same value as the
STOP frequency. The 54XXA should now be in
CW mode at the highest signal frequency for
that model.
5. Tune the spectrum analyzer to center the
54XXA output signal at the center frequency
graticule line.
6. Adjust the sp ectrum analyzer reference level
to place the to p of the waveform on the refer ence level graticule line.
7. Set the spectrum analyzer frequency span/div
to 100 kHz. The spectrum analyzer display
should resemble Figure 5-10.
8. Now set the frequency span/div to 10 mS (zero
span). Re-adjust the tuning control to place
the trace on the reference level g raticule, as
necessary.
9. View the modulation meter and ensure that
the HIGH and LOW indicators are off. Read
the frequency deviation meter and verify that
the value is within the specified limits for the
particular 54XXA model as listed in Table 1-5.

MS-DOS HANDLER SOFTWAREAPPENDIX B
B2INSTALLING AND CONFIGURING THE NI-488 MS-DOS HANDLER SOFTWARE
The following steps provide detaile d instructions f or installing the N I-488 MS-DOS Handler soft ware in
support of the GPIB-PCII/IIA card and for changing the default software configuration options of the
handler.
NOTE
When installing the MS-DOS Handler software, use only the National Instruments
NI-488 Distribution Disk for GPIB-PCII/PCIIA MS-DOS Handler, P/N 420039-09, Revision C.11. Use of any other versions of the GPIB handler software can cause interfacing
problems between the handler and the d evices on the bus.
1. Insert the NI-488 Distribution Disk fo r the GPIB-PCII/IIA MS-DOS Handler into the disk drive. At
the DOS prompt:
Type: !
Press: <ENTER> (The A:\DOS prompt will appear.)
2. Run the installation program IBSTART and specify the start up (boot) drive. For example, if C: is the
boot drive, at the DOS prompt:
Type : )"34!24 #
Press: < ENTER>
3. Follow the instructions on the display. The installation program first copies the files, GPIB.COM and
IBCONF.EXE, from the distribution disk to the root directory of the boot drive, then creates the
directory GPIB-PC on the boot drive and copies all the files on the distribution disk into this directory .
Next the program adds the line, DEVICE = GPIB.COM, to the computer’s CONFIG.SYS file so that
DOS will load the handler whenever the computer is booted. The program then prompts you to run
the hardware diagnostic program (IBDIAG) to insure the GPIB-PCII/IIA card is installed and working
properly.
4. Run the software program (IBCONF) to change the default software configuration options of the GPIB
handler. At the DOS prompt:
Typ e : )"#/.&
Press: <ENTER>
5. Follow the instructions on the display. The program firsts displays a device map for the GPIB card
(Figure B-2). Select the GPIB-PCII/IIA Card or device whose parameters you wish to display, then
press the function key, F8 . Change the configuration of the GPIB-PC-II/IIA card to that shown in
Figure B-3 and verify the configuration of the device DEV6 matches Figure B-4.
6. Reboot your computer to install the GPIB handler software and the software configuration changes.
7. Run the software diagnostic prog ram (IBTEST) to verify that the GP IB handler software is installed
correctly. To do this, at the DOS prompt:
Typ e : #$<'0)"0#
Press: <ENTER>
Type: )"4%34
Press: <ENTER>
If errors are encountered, refer to Appendix B of the GPIB-PC Users Manual, that accompanied your
GPIB board, for an explanation of the errors and their solutions.
