Module Description

The HP 70310A Precision Frequency Reference is a 1/8-width module designed to plug into HP

70000 Modular Measurement System mainframes. The HP 70310A module provides 10 MHz

and 100 MHz precision reference signals for use by HP 70000 Modular Measurement Systems

and other instruments. The HP 70310A functions either by itself, as a separate frequency

reference, or as a slave to an HP 70000 Modular Measurement System master element such as

the HP 70900A Local Oscillator. When the HP 70310A is congured as a slave, it is controlled

by the master element.

Module Options

The HP 70310A Precision Frequency Reference has the following module options:

Electrostatic Discharge Information

Electrostatic discharge (ESD) can damage or destroy electronic components. Therefore,

all work performed on assemblies consisting of electronic components should be done at a

static-safe work station.

Figure 1-4 shows an example of a static-safe work station. Two types of ESD protection are

shown: (a) conductive table mat and wrist strap combination, and (b) conductive oor mat

and heel strap combination. The two types must be used together to ensure adequate ESD

protection. Refer to Table 1-1 for a list of static-safe accessories and their part numbers.

Caution

PC board assembly edge-connector contacts may be cleaned by using a lint-free cloth with a

solution of 80% electronics-grade isopropyl alcohol and 20% deionized water. This procedure

should be performed at a static-safe work station.

Test Equipment

Before connecting any coaxial cable to an instrument connector for the rst time each day,

momentarily

Do not use erasers to clean the edge-connector contacts. Erasers generate static

electricity and degrade the electrical quality of the contacts by removing the

thin gold plating.

Do not use paper of any kind to clean the edge-connector contacts.Paper

or lint particles left on the contact surface can cause intermittent electrical

connections.

Do not touch the edge-connector contacts or trace surfaces with bare hands.

Always handle board assemblies by the edges.

Returning Instruments for Service

The original shipping containers and materials, or the equivalent, must be used when

repackaging the mainframe with modules, or modules alone.Packaging materials identical to

the original factory packaging can be purchased through any Hewlett-Packard oce.

Figures 1-5 and 1-6 show the packaging materials. When ordering packaging materials to ship

modules, it is necessary to order the proper number of foam inserts. No foam inserts are

required for a 3/8-width module such as the HP 70205A Graphics Display. One foam insert is

required for a 2/8-width module such as the HP 70900A Local Oscillator. Two foam inserts are

required for a 1/8-width module such as the HP 70902A IF Section.

Caution

Use the following procedure to prepare the instrument for shipment:

1. Fill out a blue repair card (located at the end of this manual) and attach it to the

instrument.

Addressing the Module

The HP 70310A module needs an appropriate Hewlett-Packard Modular System Interface

Bus (HP-MSIB) address to be able to communicate with the master of the HP 70000 Modular

Measurement System. The HP 70310A module's HP-MSIB address is set using the module's

ROW and COLUMN address switches.

Determining the HP-MSIB Address

The HP 70310A module has a factory-preset HP-MSIB address of 7, 19 (row 7, column 19).

Figure 2-1 shows the address map for an HP 71210A system. The addresses in this gure are

the factory-preset addresses for the modules.

Address

Figure

If the HP 70310A module is going to be used in an HP 70000 Modular Spectrum Analyzer

System where the modules all have their factory-preset addresses, the HP 70310A module

probably will not need to have its factory-preset address changed. However, if the

Installing the External Power Pack

The external power pack provides power to the HP 70310A module to maintain the

temperature in the module's internal oven/oscillator when the mainframe is turned o. An

HP 70310A Option 002 module does not have an internal oven/oscillator and, therefore, does

not need an external power pack.

Caution

The external power pack can be installed on the rear of the mainframe or on an equipment

rack. For installation information, refer to Figure 2-3 or to the instructions shipped with the

power-pack rack-mount kit.

Fuse Replacement

The external power pack's line fuse, and a spare fuse, are located in the line cord receptacle

housing on the left side of the external power pack. See Figure 2-5 for fuse removal and

replacement information.

The fuse shipped with the external power pack depends on the line voltage used in the country

of destination. Table 2-2 shows the fuse value and part number for the dierent line voltages.

Before plugging the external power pack into the ac power source, verify

that the external power pack and the power cable are not damaged, and

that the power-source socket outlet is provided with protective earth

contact. Any interruption of the protective (grounding) conductor inside

or outside of the external power pack, or disconnection of the protective

earth terminal, can result in personal injury.

Checking Module Operation

The HP 70310A Precision Frequency Reference can be congured as a separate frequency

reference (installed in an HP 70000 Modular Measurement System mainframe) or as a slave in

an HP 70000 Modular Measurement System. Module-operation checks are given below for the

following congurations:

Local Oscillator) about whether it is using an internal or external frequency reference.An

HP 70000 Series display does not have to be present in the system.

1. Connect an HP 9000 Series 200 controller (running HP BASIC 2.0, 3.0, or 4.0) to the system's

HP-IB connectors.

2. Execute the following code to display the status of the local oscillator. In line 5 below,the

local oscillator's HP-IB address is set to 718. If the factory-preset address has been changed,

modify the code to reect the current address.

Oscillator Adjustment

Oscillator Adjustment

Purpose

This adjustment is used to calibrate the HP 70310A module's internal oscillator. This

adjustment is not necessary for HP 70310A Option 002 modules, because they do not have an

internal oven/oscillator.
