IF Gain
In order to take full advantage of the RF dynamic range of the analyzer, we will offer
a switched IF amplifier with approximately 10 dB of gain. When it can be turned on
without an overload, the dynamic range is always better with it on than off. The
control “IF Gain” can be used to set the IF Gain function to Auto, or to On (the extra
10 dB) or Off. These settings affect sensitivity and IF overloads.
Enables you to control an internally switched IF amplifier with approximately 10 dB
of gain. This amplifier takes full advantage of the RF dynamic range of the analyzer.
When it can be turned on without an overload, the dynamic range is always better
when the amplifier is set to On, than when it is set to Off. The control “IF Gain” can
be used to set the IF Gain function to Auto, or to On (the extra 10 dB) or Off. These
settings affect sensitivity and IF overloads.
IF Gain Auto
Activates the auto rules for IF Gain.
Remote Command
[:SENSe]:EVMMimo:IF:GAIN:AUTO[:STATe] OFF | ON | 0 | 1
[:SENSe]:EVMMimo:IF:GAIN:AUTO[:STATe]?
Example
:EVM:IF:GAIN:AUTO OFF
:EVM:IF:GAIN:AUTO?
Notes This only applies to the RF input. It does not apply to baseband I/Q input
Dependencies This control does not appear in UXM, M9393A or M9391A
Couplings When either the auto attenuation is active (for example, with an electrical attenuator), or the optimize
mechanical attenuator range is requested, the IF Gain setting is changed using the following rule
The Auto selection 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,
the Max Mixer Level is −20 dBm or lower
For other settings, Auto sets IF Gain to ‘Low Gain’
Preset OFF
