General Information About Error Messages
• 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.
• Change Ref Level, Input Port or Attenuator (if using Hold).
The RF signal level is either too great or too small for the current
input port, attenuator setting, or both. This error often occurs
when trying to make a low-level measurement using the RF
IN/OUT port with the spectrum analyzer. Make the indicated
changes until this message is no longer displayed.
• Change RF Gen Amplitude, Output Port or Atten Hold (if on).
This message appears when the RF Generator’s Amplitude field
is set too high when using the RF IN/OUT port or when adjusting
the amplitude with the Atten Hold field set to On
.
• The RF IN/OUT port has a lower maximum output level than the
DUPLEX OUT port. Use the DUPLEX OUT port, or reduce the RF
generator’s level.
If Atten Hold is On, you may be adjusting the amplitude outside
of the allowed range. Change the amplitude
• Direct latch write occurred. Cycle power when done servicing.
• The SERVICE screen was accessed and one or more internal
latch settings were changed. Turn the instrument off and back on
to reset the latches. (This condition can occur during periodic
calibration.)
