CAL: DATA NOT STORED CAL AMP NEEDED
The correction factors are corrupt and cannot be stored. You need to perform the CAL FREQ
&
AMPTD routine before trying to store the correction factors. This message also sets SRQ
110.

CAL: FM SPAN SENS FAIL
The spectrum analyzer could not set up span sensitivity of the FM coil. (H)
CAL: GAIN FAIL
Indicates the signal amplitude is too low during the CAL AMPTD routine. This message also
sets SRQ 110. (H)

NOT found
Indicates that the CAL YTF routine for an HP 85953 cannot find a harmonic of the 300 MHz
calibration signal. If this happens, ensure that the CAL OUT connector is connected to the
spectrum analyzer input, perform the CAL FREQ
&
AMPTD routine, and then perform the
CAL YTF routine again. (U) and (H)

CAL: NBW gain failed
Indicates that one of the resolution bandwidths is not the correct amplitude for the
calibration routine. (H)
CAL: NBW width failed
Indicates that one of the resolution bandwidths is not the correct width for the calibration
