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.

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.

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:

FRONT PANEL OPERATION
3-1 INTRODUCTION
This section describes:
• The f ront panel controls and connectors
• The set up menus displayed by the front panel
keys
• The CRT screen measurement display and annotation
• The o peration of the 54XXA Scalar Measurement System using the front p anel controls and menus
• The rear panel connectors
3-2 CRT DISPLAY
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)

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 CALIBRATION key and select DETECTOR OFFSETS from the menu; then enter a zero offset value. (Refer to Section IV — Measure­ment and Calibration Procedures.)

• Selection of the measurement channel(s) affected by the TRACE HOLD key.
• Cause Cursor readout data to be displayed continuously in the lower right portion of the screen. The cursor readout d ata displayed is identical to that displayed by the CURSOR key data readout function (when invoked). This readout will not be present if an Er­ror/Warning mes sage is displayed.
• Sele ct measurement channels affected by the data smoothing function (refer to SMOOTH- ING key menus, Figure 3-24). Channel 1 or 2, or both, may be selected.
e. Plotter Address – Displays a submenu that
allows the user to s et the GPIB address for the external plotter (Figure 3-20).
f. System Applications – These menu selections
allow the user to control the following measure­ment applications functions listed below. Each is controlled by a separate submenu (Figure 3-20).
• Select trace search functions. These functions find and hold maximum/minimum trace val­ues for measur ement.
• Perform amplifier gain compression tests. This mode of operation automatically steps the signal source power output and halts when gain compression (or pre-selected out-

put level) is reached. Limits are used to detect 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, and Graticule may be set individually.
• 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:

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.
Submenus invoked from the main SAVE/RECALL key menu set up the operations described above. The selection parameters for these submenus are de­scribed in Figure 3-21.

3-13.1 Cursor Measurements Functions
The 54XXA includes the following cursor search and readout functions:
3-12.5 SELF TEST Key
This key initiates a self test of the analyzer and signal source. If the unit functions properly, the screen displays “ALL TESTS PASSED”. If the self
test fails, the screen displays a failure message. In addition, one of the f ront panel LED indicators will flash steadily to indicate a specific fault. The LED coding for Self Test errors are listed in Table A-2 in the Appendi x.

NOTE
If the NEXT MKR selection has been pre­viously selected (and if frequency markers have been set up), pressing the SELECT key will move the cursor to the next fre­quency marker.
3-13.3 CURSOR ON/O FF Key Menus
Whenever the cu rsor readout is display ed, pressing the SELECT key will invoke the cursor function main menu (Figure 3-22). The submenus selected from the main menu are us ed to se t up the curso r functions listed in paragraph 3-13.1. Using the SETUP and OPTIONS submenus, se arches may be performed using absolute search values (in dB or dBm) or using relative search values (in dBr). Rela­tive searches may also be set up by invoking the search from the RELATIVE cursor key main menu.
3-13.4 RELATIVE Cursor Key and I ndicat or
Turns Relative Cursor mode on/off. When key is pressed, a second (relative) cursor is displayed on the screen at the same position as the main cursor.
The “active” (main) cursor will then move away from this position as the data entry knob is varied. (Or it will advance to the next frequency marker position if the SELECT key is pressed—see note above). The LED indicator associated with the RELATIVE key is lit whenever this function is active.
The difference in amplitude and frequency between the “active” (main) cursor position and the relative
cursor position are displayed on the right side of the screen. The amplitude difference is displayed in dBr (dB relative to the current active cursor value). The readout display also includes readout data for the active cursor (Figure 3-22). Data for both measure­ment traces are displayed if bo th are used.
If the EXCHANGE REF CURSOR line of the menu is highlighted, pressing the SELECT key swaps the positions of the main cursor and relative cursor; oth­erwise, the CURSOR menu is selected. This feature may be used to establish the present main cursor position as the new reference frequency point for bandwidth measurements.
3-13.5 RELATIVE Curs or Key Men u
Pressing the SELECT key with the relative cursor data displayed invokes the main menu for t he rela­tive cursor function. This menu is similar to the main menu for the main cursor. All searches initiated from this menu will be performed relative to the value at the current m ain cursor position, or to the peak value for the channel selected (Fig­ure 3-22).
3-13.6 BANDWIDTH Search Function
Selecting the BANDWIDTH curs or s earch t ype from the cursor submenus will set up the 54XXA to per­form bandwidth measurements. The search value (absolute or relative) must be specified (in dB) as part of the menu selection. An example of this type of measurement is shown in Figure 3-11.

The HARD COPY key group is shown in Figure 3-12. The main menus and submenus associated with these keys are described in Figure 3-23 (behind Op­erating Menus tab).
NOTE
Before data can be sent to an external plotter, the 54XXA GPIB interface must be set to the Plotter Mode; see Fig­ure 3-23. (In this mode of operation, only the 54XXA and plotter may be connected to the GPIB; refer to S ection II .
3-14.1 MENU Key
Displays one of two main menus that enable the user to select the type of hard copy output that is pro­duced from the measurement data. These menus configure the 54XXA to output data to either a printer or a plotter (Figure 3-23). The printer output may be either a tabular printout of the measurement
data, a “plot” of the screen display, or both (Fig­ures 3-14 thru 3-17).
• Plot graticule lines, cursor information, titles, or measurement traces, from the screen display separately .
The main menus and submenus are explained in Figure 3-23. Examples of hard copy print outs are shown in Figure 3-14 through 3-17.
3-14.2 PRINTER/ PLOTTER Indi cators
When lit, these LED indicators designate which type of hard copy output the 54XXA is set up to produce.
3-14.3 START Key
Freezes the displayed data and lo ads the printer or plotter buffer with the measurement data. When data transfer is complete, the output device starts printing or plotting and the 54XXA is again usable for measurements. The type of hard copy produced is determined by the last PRINTER/PLOTTER MENU options selected.
When plotter ou tput is used, Pl ot Pro gress M essages that indicate normal and abnormal plotter condi­tions are displayed in the menu area at the right side of the screen. Plot progress messages are transient; they are only displayed momentarily . The menu area returns to the previous display when the output data transfer is completed. These messag es are listed in Table 3-1.
Either menu may be accessed from the other; both types of hard copy output may be defined before output begins. The PRINTER and PLOTTER LEDs indicate which hard copy output device has been defined. The output options available from these menus are:
• Print the screen measurement display on a printer.
• P rint a tabulation of the measurement values (printer only) .
3-14.4 STOP Key
Stops Hard copy output operation. If output is to printer, stop may be delayed, depending on size of printer buffer (if any). If to plotter, the current data string is plotted and the plotter is left in a reset state.
If both hardcopy output devices are active, only the device indicated by the LEDs will be stopped. T o stop the other device, select the appropriate hard copy main menu then press STOP.

This form of data smoothing retains measurement bandwidth, but requires more time to generate the measurement data and display. It is an effective method of re ducing the effe cts of random type n oise in the measurement data.
3-15.2 SMOOTHING Key, Indicators and Menu
Displays a menu that allows five levels of trace smoothing filtering to be selecte d for the channel(s) selected (Figure 3-24). This form of data smoothing reduces the effective bandwidth of the measurement display system and requires some extra time; how­ever, the display is correct aft er just one swee p.
3-15.3 Smoothing Mode Selection
Selection of the measurement channel(s) acted on by the SMOOTHING submenu selections is done from the ANALYZER configuration submenu, which is invoked from the SYSTEM MENU Key main menu (Figure 3-20). The ANALYZER submenu allows the user to set for COUPLED smoothing (i.e., measure­ment Channels 1 and 2, are set to the same data smoothing level), or INDEPENDENT smoothing (i.e., measurement channels may be set to different lev­els). When a channel selection is made, the CHAN-
NEL 1 and/or CHANNEL 2 LED indicator next to the SMOOTHING key will be lit accordingly.

SECTION IV
MEASUREMENT AND CALIBRATION
PROCEDURES
4-1 INTRODUCTION
This section describes:
How to check that the instrument is operating
•
properly. How to perform a measurement setup calibration.
•
How to make transmission, return loss, power,
•
and alternate sweep frequency range measure­ments.
4-2 OPERATIONAL 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 TESTS PASSED” 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.
4-3 CALIBRATION 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.
4-3.1 Calibration 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 the NETWORK ANALYZER menus for Channel 1 and/or Channel 2 to perform absolute power measurements. Refer to Table 4-6 (page 4-14).
4-4 MEASUREMENT 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.
4-4.1 Transmission 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 OM 4-3
Page 56
OPERATIONAL CHECKOUT PROCEDURE IV MEASUREMENT AND CALIBRATION PROCEDURES
shown in the table. The typical equipment setup for these types of measurements is shown in Figure 4-1.
4-4.2 Alter 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.
4-4.3 Ratio 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 NETWORK ANALYZER 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 RF OUTPUT level is changed during the test.
4-4.4 Absolute 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.
4-4.5 Other Measurement Procedures
Additional information pertaining to 54XXA meas­urement procedures are included in the three appli­cation notes that are located behind the “Supple­ments/Options” tab at t he rear of this manual:

5-7 SIGNAL 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.
5-7.1 DC 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 “DC CAL 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.
10. Repeat step 9 for the remaining two voltag e values in Table 5-3a.
11. Repeat steps 2 to 10 for signal channel inputs B and R.

5-7.2 50MHz 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).

5-8 RESIDUAL 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.
a. E quipment Required
Anritsu MS2802 Spectrum Analyzer. Marconi TF 2304 Modulation Meter.
b. Procedure
1. Set up the equipment as shown in Figure 5-9, 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 the OUTPUT 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.

B2 INSTALLING 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.
