General Information
Introduction
The HP 70993A Installation and Verification Manual contains information needed to install
and verify the HP 76903A IF Section. For information on instailing and verifying HP 70000
Modular Measurement Systems, refer to the installation and verification manual for the
system master (for example, HP 7096OA Local Oscillator).
This manual contains the following five chapters:
Chapter 1, General Information, describes the module and its accessories, gives
electrostatic discharge and packaging information, and lists Hewlett-Packard Sales and
Service Offices.
Chapter 2, Installation, provides information for configuring and installing the module
in an HP 79900 Modular Measurement System.
Chapter 3, Specifications, lists module specifications and characteristics.
Chapter 4, Verification, contains tests required to verify module specifications.
Chapter 5, Troubleshooting, e&ins the probable cause(s) indicated by front-panel
status/error LEDs, and lists the error codes that can be produced or caused by the
HP 70903A IF Section.
Module Description
The HP 70903A IF Section is a l/&width module, providing a resolution bandwidth of
100 kHz to 3 MBz, designed for use in HP 70000 Modular Measurement Systems. The module
processes a 21.4 MHz signal from a spectrum analyzer RF Section or external mixer interface
module. A detected video signal is produced and routed to the video processor in the local
oscillator. The module contains resolution bandwidth filters, log amplifiers, detection circuitry,
and video filters. The HP 70903A can be used with an HP 70902A in a single system to
provide resolution bandwidths of 10 Hz to 3 MHz.
The HP 70903A is a slave module and as such is controlled by the system master.
General Information 1-l
Modular Measurement System Terms
Understanding the following terms is essential to understanding HP-MSIB (Hewlett-Packard
Modular System Interface Bus) addressing and the structural relationships among modular
system devices.
Functional Terms
Modular system devices may be combined to allow them to communicate and operate as
an instrnment. The following terms identify the interrelationships among devices within a
modular instrument.
Element: Any device that communicates over the HP-MSIB (for example, HP 70903A
IF Section). In contrast, the HP 70001A Mainframe coordinates all HP-MSIB
communications, but does not communicate over the HP-MSIB and therefore is not an
element.
Master: An element that controls other elements.
Sub-master: An element that simultaneously controls other elements and is controlled
by other elements. .
Slave: An element that is controlled by another element.
Independent element: An element that is neither a master or a slave (for example,
HP 70206A System Graphics Display).
Instrument: An element, or group of elements that performs an independent function
(for example, HP 71300A Millimetre Spectmm Analyzer).
Structural Terms
Modular systems consist of hardware stmctures dedicated to specific functions. The structural
terms used in reference to these functions are described below.
Main.l&ne: A mainframe is the device into which plug-in modules may be installed to
create an instrument such as a modular measurement system.
Module: Modules are devices that plug into a mainframe. They cannot function
without a mainframe.
Stand-Alone Instrument: An HP-MSIB element capable of performing its functions
without a mainframe (for example, HP 79206A System Graphics Display).
19 General Information

l-4 General Information
Front/Rear-Panel Features
Figure l-2 shows the HP 70903A front- and rear-panel features.
Front-Panel Status Indicators
It is normal for both of the front-panel status LED indicators to flash on, then off, during the
module self-test. Self-test occurs each time the instrument is turned on. Listed below are
other reasons why each status LED might light.
ACT (Active)
LED
The green ACT LED active indicator of a slave module turns on when the module is making
a measurement and its master has keyboard control of the display. Refer to Chapter 5 for
additional detail related to ACT LED.
Note The ACT LED of a slave module is only operative when there is a display in
the system or when the instmment is performing a self-test.
ERR (Error) LED
The red ERR LED lights when there is a problem (error) related to the module. Refer to
Chapter 5 for additional troubleshooting information.
Front-Panel Outputs
Note The output levels described for both front- and rear-panels are typical and
only apply if a 21.4MHz signal, at a nominal level of -5 d.Bm, is applied to
the 21.4MHz input on the rear panel.
3
VfDEO 0-1V
This BNC (m) connector provides an auxiliary 0-1V video output.
fF 21.4MHz
This BNC (m) connector provides an auxiliary 21.4MHz IF signal output of approximately
-15 dBm.
Module Latch
The module hex-nut latch secures the module in an HP 70000 Series mainframe. When the
module is being installed or removed from a mainframe, an 8 mm hex-ball driver is used to
turn the module latch. Refer to Chapter 2 for information on module installation.
General Information l-5
Rear-Panel Inputs and Outputs
21.4MHz IN
This SMB (m) input connector receives a 21.4-MHz signal, at a nominal level of -5 dBm,
from the RF section.
21.4.MHz OUT
This SMB (m) output connector is used when cascading signals iu a HP 70000 Modular
Measurement System that has two IF sections.
VIDEO OUT
This SMB (m) output connector supplies a typical 0-2V video signal to the system master
(for example, HP 70900A Local Oscillator).
Note In an HP 70000 Modular Measurement System that has two IF sections, the
21.4 MHz-IN and Video OUT from the HP 70902A are cascaded through the
HP 70903A before connecting onto the RF section and system master. Refer
to Chapter 2, "Installation. "
VIDEO IN
This SMB (m) connector receives the video output from an HP 79902A when two IF sections
are used in an HP 70000 Modular Measurement System.
LINEAR AGC VIDEO
This SMB (m) connector provides an uncorrected, linear video output signal, the peak value
of which is leveled to 1V nominal and is linearly related to the RF input. This output is
indepedent of the spectmm analyzer ' internal IF gain setting. Therefore, changing the
s
reference level will not disturb the amplitude of the linear video output.
The Linear AGC Video output is also compatible with the HP 709024 IF Section. Since in a
dual IF system the HP 70902A ' video is connected through the HP 70903A, the video from
s
the HP 70902A will also be linearized.
After demodulation, the following applications may be performed:
n Audio monitoring.
= Video monitoring.
l Measuring rise and fall time in pulse evaluation.
l Digitizing for data processing and storage.
Mainframe/Module Interconnect
This multiple-pin connector plugs into the mainframe and provides power-supply voltages and
HP-MSIB connections for module communication and control.

caused by ESD.
b. For instruments that weigh less than 54kg (120-lb), use a double-walled,
corrugated cardboard carton of 159-kg (350-lb) test strength.
c. The carton must be large enough to allow three to four inches on all sides of
the instrument for packing material and strong enough to accommodate the
weight of the instrument.
d. Surround the equipment with three to four inches of packing material, to
protect the instrument and prevent it from moving in the carton.
e. If packing foam is not available, the best alternative is S.D.-240 Air Cap from
Sealed Air Corporation (Commerce, California 90001). Air Cap looks like a
plastic sheet filled with l-1/4 inch air bubbles.
f. Use the pink (anti-static) Air Cap to reduce static electricity. Wrapping the
instrument several times in this material will protect the instrument and
prevent it from moving in the carton.
3. Seal the carton with strong nylon adhesive tape.
4. Mark the carton ` FRAGILE, HANDLE WITH CARE '.
5. Retain copies of all shipping papers.

Introduction
This chapter contains information needed to install the HP 70903A into an HP 70000 Series
mainframe and to configure and cable the HP 70903A for use in an HP 71100A or 71210A
spectrum analyzer. These examples cover the HP 70903A cabling requirements for either a
single or dual IF section configuration. Cabling for single- and dual-IF systems is shown in
Figure 2-3 and Figure 2-4, respectively. Depending on the number of IF sections required,
one of the two examples will apply when cabling the HP 70903A in other HP 70000 Series
spectmm analyzers
The information presented is general in nature. For more detailed information on spectrum
analyzer con&uration and HP-MSIB addressing, refer to the installation and verification
manual for the system master (for example, HP 70900A Local Oscillator).
Preparation for Use
Installation of the module into an HP 70000 Modular Measurement System requires the
following steps:
n Addressing the module
n Installing the module in a mainframe
n Connecting the rear-panel cables
When properly instaed, the HP 70903A D? Section obtains both power and interface-bus
control through the module rear-panel mainframe/moduIe interconnect. After the module is
installed, refer to Chapter 4 to ensure the module is operational.
Addressing and cabling examples in this chapter apply to both HP 71100A and HP 71210A
spectrum analyzers. For more detailed information about HP 70000 Modular Measurement
System configuration, cabling, and addressing, refer to the installation and verification manual
for the system master (for example, HP 709OOA Local Oscillator).
Installation 2-1
Addressing the Module
The HP 70903A needs an appropriate HP-MSIB (Hewlett-Packard Modular System Interface
Bus) address to allow communications with the system master. The HP 70903A module
HP- `MSIB address is set using the module ' ROW and COLUMN address switches.
s
Determining the HP-MSIB Address
The HP 70903A has a factory-preset HP-MSIB address of 2, 18 (row 2, column 18). Table 2-l
shows the address map for an HP 71210A Microwave Spectrum Analyzer. The addresses
in this table are factory-preset for modules in this system. Refer to the installation and
verification manual for the system master for instructions on how to display the instmment
address map.
Table 2-l. Typical Address Map
Note The factory-preset addressing of a HP 70903A need not be changed if it is
used with other factory-preset modules. If other modules in a system have
been changed from factory-preset addresses, the HP 70903A may require
readdressing.
2-2 lnstalfation
Setting the HP-MSIB Address Switches
A module-address change requires the following steps:
1. Locate the address switches on the right side-panel of the module. See Figure 2-l for
an example of the switches.
2. Set the address switches labeled "row " to the binary value of the module ' HP-MSIB
s
row number. For example, if the row value is 2, set the switches to binary 010 as
shown in Figure 2-l.
3. Set the five switches labeled "column " to the binary value of the module ' HP-MSIB
s
column number. For example, if the column value is 18, set the switches to binary
10010 as shown in Figure 2-l.
Note Changing HP-MSIB addresses requires an understanding of HP-MSIB
addressing rules. For information on determining and assigning HP-MSIB
addresses, refer to the installation and verification manual for the system
3 master (for example, HP 70900A Local Oscillator).

Specifications
There are no specifications for the HP 70903A IF Sections. For system-level specifications and
characteristics, refer to the installation and verification manual for the system master.
Specifications 3-1
Verification
Introduction
This chapter normally contains module performance-verification tests, which evaluate the
electrical performance of the module against its specifications. Since there are no module
specifications for the BP 7090314 IF Section, no module performance-verification tests apply.
Firmware
The HP 70903A IF Section will work with any HP 70900A Local Oscillator (LO) firmware
versions. However LO firmware dated 889314 and later provides a different menu display than
older firmware. In a spectrum analyzer with a display, the LO ROM version can be checked
by pressing pi, vb and 71 softkey.
Performance Verification Tests
Tests available for performance verification and operational readiness are listed below.
n Power-On Self-Test
n System Diagnostics
8 System Analyzer Operation Verification
n HP 11990A System Performance Programs
Power-on Self-Test
A module self-test is performed on all modules in an HP 70000 Modular Measurement
System each time the instmment is turned on. This test verifies the ability of the module to
communicate with the system controller on the system bus (HP-MSIB). During this self-test,
the ACT (tiive) and ERR (error) status-indicator LEDs will blink on, then off, as the
analyzer checks the operation of each module. If the LEDs stay on or continue to blink, refer
to Chapter 5, "Troubleshooting. The results of this test can be determined by examining the
"
front-panel indicator LEDs and performing the following steps.
m An instrument with LO fimware dated 880314 or later will display any errors
encountered after the self-test is complete.
m An instrument with LO firmware dated 876501 or earlier will not automatically display
errors after completion of self-test.
Press IEk
o Note any error statement referring to the IF Section. (709038 will be part of
the error code.)
o If any error statements referring to the HP 70903A are displayed, refer to
"Error Messages " in Chapter 5.
Verification 4-1
System Diagnostics
System Diagnostics is a downloadable (DLP) program that is downloaded into each standard
HP 70090 Series system shipped to a customer. A DLP is a sequence of HP-IB codes which
resides in the RAM of the LO and can be executed from within the analyzer at the press of a
key. DLPs do not go away when power is turned off, so they can be put in an instrument and
used repeatedly.
The purpose of System Diagnostics is to determine if any catastrophic failure has occurred in
the spectrum analyzer and, further, to determine where the failure occurred. A catastrophic
failure is a failure which renders the instrument unusable.
A secondary purpose of System Diagnostics is to determine if any "soft " failures have occurred
and to diagnose, to the module level, where the "soft " failure occurred. A "soft " failure is
defined as a failure which renders some circuitry of the instrument unusable or beyond its
proper operating limit.
The HP 70903A IF Section tests are included in System Diagnostics and will be performed
if an HP 70903A IF Section is included in the spectrum analyzer under test. The System
Diagnostics DLP tests are available on disks for down-loading into HP 70900 Modular
Spectrum Analyzers. Contact the nearest HP Sales and Service Office to obtain these disks.
The following part numbers are for use with systems with LO firmware 861015 or later.
n Order HP part number 70900-10025 for 5-l/4 inch disks
n Order HP part number 70909-10026 for 3-l/2 inch disks
System Operation. System Diagnostics
Diagnostics requires the presence of a 300 MHz
signal at -10 dBm input to the RF INPUT of the anal zer, nominally the CALIBRATOR
OUTPUT of the HP 70900A. Upon pressing theI softkey, a menu will appear
System d1a.g
with the message Select Desired System to Test. Once the calibrator has been connected
and selection of a system has been made, no further user interaction is required. System
Diagnostics will run and exit with one of the following messages:
8 Test Completed
m Addressing Error
8 Test Aborted Early
In addition, any error messages will be displayed on the screen. Depending on which failure
occurs, System Diagnostic6 may not run to completion. Refer to Chapter 5 of this manual for
a list of error messages. Refer to the troubleshooting chapter of the system master installation
and verification manual for more details on test results.
Caution As programs are down-loaded, any previously stored DLPs are erased from
memory. It is imperative that backup copies of all DLPs-including System
Diagnostics programs-be maintained.
4-2 Verification
Spectrum Analyzer Operation Verification
It is possible to verify the electrical performance of the entire spectmm analyzer, including log
fidelity and resolution bandwidth of the HP 70993A IF Section, by using System Verification
Programs. Refer to the installation and verification manual for the system master regarding
system verification programs.
System Performance
It is possible to check the calibration of various functions and overitu performance of the
HP 709038 IF Section by using HP 11990 System Per&ormance Tests. For information related
to these tests, refer to the installation and verification manual for the system master. These
programs are available from the nearest HP Sales and Service Oflice.

Troubleshooting
Introduction
This chapter provides information on the front-panel status indicator lights and the error
messages produced by the HP 70903A IF Section. If problems are encountered, review
Chapter 2 of this manual to ensure the module addressing switches are properly set, cabling
is correct, and the module is securely seated in the mainframe. If problems persist, refer to
the installation and verification manual for the system master for troubleshooting tools or
EP 70903A IF Section Service Manual for component-level information.
Troubleshooting Tools
The modular spectmm analyzer has the following troubleshooting tools.
Indicator lights
Error message reporting
Display tests
Analyzer tests
The following troubleshooting programs are available for use with HP 70000 Modular
Measurement Systems.
8 System Diagnostics
8 System Operation Verification
Refer to the "Troubleshooting " chapter in the installation and verification manual for the
system master for a description of these tools and programs.
Status Indicators
There are two status-indicator LEDs located on the front panel. It is normal for both of the
front-panel status LED indicators to flash on, then off, during the module self-test. Self-test
occurs each time the instrument is turned on. The following pages list reasons why each
status LED might light.
Troubleshooting 5-1
STATUS ACT
Note The ACT LED of a slave module is only operative when there is a display in
the system or when the instrument is performing a self-test.
The ACT LED of a slave module turns on when:
n The module is performing a function directed by manual control of the display
keyboard.
n The module is making a measurement and its master has keyboard control of the
display.
n The instrument is in self-test mode.
Refer to the installation and verification manual for the system master for additional detail
related to ACT LED.
STATUS ERR
The module error indicator, the ERR LED, indicates that the module has an error condition.
If the module is a slave, then the error light of both the slave and its master will indicate the
error condition.
l The ERR LED flashes at a 1 Hz rate when communication over HP-MSIB is not
satisfactorily completed.
n If the error indicator LED of more than one of the spectrum analyzer ' modules flash
s
at a 1 Hz rate simultaneously, refer to the installation and verification manual of the
System master.
n Some errors may only be present when the spectrum analyzer sweeps; this causes the
error indicator to flash at the sweep rate.
Note It is possible that a module may dismpt all HP-MSIB communication without
its own error indicator flashing.
Caution Do not remove the module side covers. A complete electrical alignment
of the module is required when the side covers are removed. Refer to the
HP 70903A IF Section Service Manual for alignment procedures.
Module Self-Test
During module self-test, which occurs each time the analyzer is tnmed on, the ACT (Active)
and ERR (error) LEIk will blink on momentarily as the analyzer activates and checks the
module If the LEDs continue to blink, or remain lit, this is an indication of a problem.
5-2 Troubleshooting
Error Messages
Spectrum-analyzer error-messages generated by an HP 70903A are listed in this section. The
