SERVICE SUPPORT

GENERAL INFORMATION

more than 30 pages of service messages and data. The 373XXA will automatically remove the oldest errors first to make room for new er- rors, if necessary. To check the contents of the service log, use the pro- cedure described in Chapter 3, Operational Tests.

 

NOTE

 

A printed or disk file copy of the Service Log (with the fail-

 

ure in question) must be made available to ANRITSU

 

when exchanging a failed assembly, or when requesting

 

service support. Refer to Chapter 2, Replaceable Parts, for

 

further information.

System

Quick operational checkout of the system may be accomplished by the

Test/Certification

system user or for incoming inspection purposes using the “Operational

 

Checkout” chapter in the 373XXA Operations Manual. Those procedures

 

are useful in quickly verifying that the instrument’s primary measure-

 

ment functions are operational and stable.

 

Full operational testing of the system is detailed in Chapter 3, Opera-

 

tional Tests. These tests should be performed annually, or more often

 

depending on system use.

 

Verification of the system’s measurement accuracy and other key per-

 

formance parameters may be done using the procedures in Chapter 4,

 

Performance Verification. This should be performed annually, or more

 

often depending on system use.

Preventive Service

The 373XXA A9 Processor PCB contains a battery backed memory/real

 

time clock chip (BBRAM) and a static memory (SRAM) backup battery.

 

These have a finite life span and should be replaced periodically per the

 

procedures in Chapter 8, Removal and Replacement Procedures.

 

The BBRAM chip has a rated life span of 4 years. The SRAM backup

 

battery has a worst case elapsed time for SRAM battery protection of

 

200 days. The SRAM battery life span will vary according to how the

 

system is used; that is, how often the system is powered off for ex-

 

tended periods of time.

Servicing Specially

Instruments with customer requested special modifications performed by

Modified Instruments

ANRITSU will have an identifying Specials Modification number printed

 

on the rear panel. This number will be preceded with the letters SM, i.e.,

 

SM1234 is special modification number 1234.

 

Special instruments may have service requirements different from

 

those specified in this manual. Contact your local Service Center if you

 

need more information when servicing such instruments.
