Stored data is invalid

An attempt was made to reference normalized data when normalized data was invalid.

 

 

Parameter change not permitted

An attempt was made to change a parameter while IF cal was active. It is not ex-

tory.

 

 

Calibration may not be valid

An attempt was made to repeat the previous calibration when there was no record of a

 

previous calibration.

 

 

Calibration does not exist

An attempt was made to turn on flat power correction or vector error correction when

 

the corresponding calibration does not exist.

 

 

Current calibration is erased

When turning on Multiple Source Mode with vector error correction on, the calibration

 

is destroyed. Not really an error. Message is issued as a warning.

An attempt was made to turn on a time domain mode but the current 373XXA state

 

does not permit it.
