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:

This input allows the use of an external-reference signal. The external-reference input signal

can have a frequency of 1, 2, 5, or 10 MHz, and a power range of05 to +21 dBm. TTL signal

When an acceptable external-reference signal is applied to the EXT REF input, the module

automatically switches to the external reference.

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

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.

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.
