Installation 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.
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 ’s ROW and COLUMN address switches. Determining the HP-MSIB Address Table 2-l The HP 70903A has a factory-preset HP-MSIB address of 2, 18 (row 2, column 18). shows the address map for an HP 71210A Microwave Spectrum Analyzer.
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 ’s HP-MSIB 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 ’s HP-MSIB column number.
Installing the Module in the Mainframe The HP 70903A must be installed in an HP 70000 Series mainframe. This is accomplished by following the procedure below. Figure 2-2 identifies the module and mainframe parts called out in the procedure. To avoid blowing the mainframe line fuse or internal module fuses, the mainframe power must be turned off before connecting or disconnecting modules. Caution # Module Installation 1. Turn the mainframe LINE switch off. 2 . Open the mainframe front-panel door. 3 .
Connecting the Rear-Panel Cables This section contains instructions for connecting the rear-panel cables to an HP 70903A in either an HP 71100A or an HP 71210A spectrum analyzer single-IF ’and dual-IF section system, respectively. The cables supplied with an HP 70903A module that was ordered separately allow it to be installed as shown in the examples. Longer cables must be ordered for other configurations.

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.
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.
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.
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.
5 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.
STATUS ACT 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.
