Verbose/Correction Information
When Swept IF Gain is manually set to Low, you cannot set
the FFT IF Gain to High because that would make the
Reference Level couplings wrong in FFT mode.
If you are using level gating, you cannot select the FFT Gate
Method.
The gated LO function turns the LO on and off as it sweeps.
So the FFT sweep type is not available if you have selected
gated LO.
The FFT sweep type is not available if you have selected the
gated video function.
Since FFT's do not sweep, you cannot use a Tracking Source
while doing FFT's
If a Marker Function is on for a Fixed marker, the marker's
reported value is derived from the function. Therefore, you
cannot directly set the X or Y value of a Fixed marker that has
a marker function turned on.
If Normalize is on the Amplitude scale is in dB units, so
adjusting the Y value of a Fixed marker is not possible.
The electronic attenuator does not function above 3.6 GHz.
So if you have that attenuator enabled, you cannot change
the center frequency so that frequencies above 3.6 GHz are
displayed/measured.
The frequency offset feature cannot be used when you have
selected a log scale for the frequency axis.
The feature cannot be used when you are using a Tracking
Source.
You cannot center or adjust the preselector because the
Microwave Preselector is currently off
You cannot use level triggering to control the gate if you are
using the FFT gating method.
You cannot use level triggering to control the gate when you
are using the currently selected gate source.
