Chapter 6
Operator Maintenance

6-1

Introduction

This chapter provides the information necessary for operator mainte-
nance of the signal generator. Operator maintenance is limited to trou-
bleshooting and repairs that can be made without removing the
instrument covers.

Error and
Warning/Status
Messages

During normal operation, the MG369XB generates error messages to
indicate internal malfunctions, abnormal signal generator operations,
or invalid signal inputs or data entries. It also displays warning mes-
sages to alert you of conditions that could result in inaccurate signal
generator output. In addition, status messages are displayed to remind
you of current menu selections or settings.

Self-Test Error
Messages

The MG369XB firmware includes internal diagnos-
tics that self-test the instrument. These self-test di-
agnostics perform a brief go/no-go test of most of the
instrument PCBs and other internal assemblies.

You can perform a signal generator self-test at any
time during normal operation by pressing

System

and then the System Menu soft-key

Selftest

.

If the signal generator fails self-test, an error mes-
sage(s) is displayed on the front panel data display.
These error messages describe the malfunction and,
in most cases, provide an indication of what has
failed. Table 6-1, pages 6-4 through 6-6, is a sum-
mary listing of the self-test error messages. Included
for each is a description of the probable cause(s),
whether or not the MG369XB is still operable, and if
operable, what operational degradation can be ex-
pected.

MG369XB OM

During self-test with

RF OUTPUT

set to

ON

, the output

power level is set to 0 dBm. Always disconnect sensitive
equipment from the unit before performing self-test.
