Log board
Cause: The 70903A IF Section log board signal amplitude is too low.
Cure: Perform the HP 70903A IF section log amplier adjustments. If this does not remedy the
problem, the A2 Log Amplier Assembly requires repair.
0034
Problem/ampl
low?
Cause:
The
HP
70903A
IF section internal 21.4 MHz IF signal amplitude is too low.The
program
stops
testing
the
HP 70903A IF section when this error is generated.
Cure: Perform the HP 70903A IF section module adjustments. It is likely either the A1 LC
wideband lter or A2 log amplier/power supply requires repair.

Step
gain
amplifier
Cause:
The
gain
of
the
step
gain
amplier
of
the
HP
70903A IF section is incorrect.
Cure:
The
step
gain
ampliers
in
the
HP
70902A
IF
section require adjustment or repair.

Res BW-accuracy
Cause: One or more of the HP 70903A IF section resolution bandwidths are not the correct
value.
Cure: The bandwidth lter adjustments in the HP 70903A IF section should be performed. If
this does not remedy the problem, repair the HP 70903A IF section LC bandwidth lters.
0037
Res BW-amplitude
Cause: The amplitude variation between the HP 70903A IF section resolution bandwidths is too
large.
Cure: The bandwidth lter adjustments in the HP 70903A IF section should be performed. If
this does not remedy the problem, repair the HP 70903A IF section LC bandwidth lters
.
0038
Calibration atten
Cause: One or more of the calibration attenuators of the HP 70903A IF section are not
functioning correctly.
Cure: The calibration attenuators in the HP 70903A IF section require adjustment or repair.
