Meas Setup
settings affect sensitivity and IF overloads.
IF Gain Auto
Activates the Auto Rules for IF Gain When Auto is active, the IF Gain is set to High Gain under any of
the following conditions:
• the input attenuator is set to 0 dB
• the preamp is turned On
• the Max Mixer Level is 20 dBm or lower
For other settings, Auto sets IF Gain to Off. And there are only two choice: Low Gain and High Gain.
Low Gain is best for large signals and High Gain is best for small signals.
IF Gain State
Selects the range of IF gain. On sets the high gain option, which allows for better noise level
measurements and Off sets low gain when measuring large signals.

Dependencies/Couplings When either the auto attenuation works (for example, with the electrical
attenuator) or optimize mechanical attenuator range is requested, the IF
Gain setting is changed according to the following rule.
‘Auto’ sets IF Gain to ‘High Gain’ under any of the following conditions:
the input attenuator is set to 0 dB, the preamp is turned on, or the Max
Mixer Level is 20 dBm or lower. For other settings, ‘Auto’ sets IF Gain to
‘Low Gain’.
