Settings conflict; FFT IF
Gain High not available when
Swept IF Gain = Manual Low
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.
–221
Settings conflict; FFT
method is unavailable for
level gating
If you are using level gating, you cannot select the FFT Gate
Method.
–221
Settings conflict; FFT sweep
type is not available while
in Gated LO
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.
–221
Settings conflict; FFT sweep
type is not available while
in Gated Video
The FFT sweep type is not available if you have selected the
gated video function.
–221
Settings conflict; FFT
Sweeps unavailable in
Tracking Source mode
Since FFT’s do not sweep, you cannot use a Tracking Source
while doing FFT’s
–221
Settings conflict; Fixed
marker adjust not available
while Marker Function is on
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.
–221
Settings conflict; Fixed
Marker Y value is not
adjustable with Normalize On
If Normalize is on the Amplitude scale is in dB units, so
adjusting the Y value of a Fixed marker is not possible.
–221
Settings conflict; Freq >
3.6 GHz unavailable while
electronic attenuator
enabled
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.
–221
Settings conflict; Frequency
Offset not available when
Frequency Scale is Log
The frequency offset feature cannot be used when you have
selected a log scale for the frequency axis.
–221
Settings conflict; Function
not available in Tracking
Source mode
The feature cannot be used when you are using a Tracking
Source.
–221
Settings conflict; Function
unavailable with MW Presel
off
You cannot center or adjust the preselector because the
Microwave Preselector is currently off
–221
Settings conflict; Gate
control is Edge for Gated
FFT
You cannot use level triggering to control the gate if you are
using the FFT gating method.
–221
Settings conflict; Gate
control must be Edge for
this Gate Source
You cannot use level triggering to control the gate when you
are using the currently selected gate source.
