Error Messages

General Information About Error Messages

• Input value out of range.

A number was entered that was too large or small for the selected field, for example, trying to set AFG1 Freq to 125 kHz.

• Invalid keystroke.

You used a key that has no function relating to the selected field, for example, pressing the On/Off key while the Filter 1 field is selected.

• Option not installed.

You selected a function that requires optional hardware that is not present.

• Turn off either AM or FM settings.

You tried to create simultaneous AM and FM (using any combination of AFGen1, AFGen2, and the Mod In To field). The Test Set does not provide simultaneous AM and FM.

Squelch interrupt overflow. Reset using Meas Reset (press and release the Shift key, then the Hold key).

The Test Set temporarily interrupts audio measurements when squelch is first broken to prevent internal switching transients from influencing measurements (except when using the SCOPE, SPEC ANL, SERVICE screens). If squelch is repetitively broken in a period of a few seconds, the duration of measurement interruption becomes too great, and the Test Set stops interrupting the signal. Following measurements may be influenced by transient signals.

Meas Reset clears the data buffer used to generate interrupts, resetting the normal squelch operation to eliminate transients.

This condition may occur when monitoring low-level off-the-air signals.

• Cal file checksum incorrect - initializing file.

This error usually occurs after changing the Test Set’s firmware ROM’s. It is not a problem in that instance, but should not re-appear during subsequent operation of the Test Set.

• One or more self tests failed. Error code: XXXX

An instrument failure was detected when the Test Set was turned on. (For example, having a stuck front-panel key during turn on.) The numbered error message corresponds to a binary-weighted group of errors listed in the *TST Common Command description in the Programmer’s Guide.
