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.
