List of Text Only Error Messages
Operation errors generally occur when you try to do something the Test Set was not
designed to do. Most messages tell you what to do to correct the problem, (turn something
off, reduce a field’s value, press a certain key, and so forth).
Some common messages are listed here:
All self tests passed.
The Test Set did not detect any hardware or firmware failures during its initial self-
diagnostics. This message should always be displayed immediately after instrument turn
on.
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.
Cannot make call at this time.
This error message appears when a call is attempted while the Test Set is performing
another call processing function, such as registration. Press the END CALL key and
attempt the call again.
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.
