analyzer, the dynamic range is always better with it on than off. The Swept IF Gain key can be used
to set the IF Gain function to Auto, or to High Gain (the extra 10 dB), or to Low Gain. These
settings affect sensitivity and IF overloads.
This function is only active when in Swept sweeps. In FFT sweeps, the FFT IF Gain function is
used instead.

Notes where ON = high gain
OFF = low gain
Couplings The ‘auto’ rules for Swept IF Gain depend on attenuation, preamp state, start and stop frequency
and the setting of FFT IF Gain. Set the Swept IF Gain to High (On) when the total input
attenuation is 0 dB, the preamp is off, the start frequency is 10 MHz or more, and the FFT IF Gain
is autocoupled, or manually set to Autorange, or manually set to High. Also set the Swept IF Gain
to High (On) when the total input attenuation is 2 dB or less, the preamp is on, the start
frequency is 10 MHz or more, and the stop frequency is 3.6 GHz or less and the FFT IF Gain is
autocoupled, or manually set to Autorange, or manually set to High. Under all other
circumstances, set the Swept IF Gain to Low (Off).
If the sweep type is Swept, the start frequency of the instrument is less than 10 MHz, and you
put Swept IF Gain in Manual On, a warning condition is generated and remains in effect as long
as this condition exists. The warning message is about a possible IF overload.
As with most parameters with an AUTO state, AUTO COUPLE sets it to Auto, and setting any
specific value (for example on or off) will set the AUTO state to false.
Preset Auto after a Preset which yields Off unless the Preamp is on.
Auto and Off after Meas Preset.
State Saved Saved in instrument state.
