–221 Settings conflict; Gate is 
not available when Marker 
Count on
The gate function cannot be used while you have marker 
count turned on.
–221 Settings conflict; Gate 
Length is not settable in 
FFT sweeps
The sweep time for FFT sweeps is set by the calculations. So 
sweep time settings cannot be adjusted.
–221 Settings conflict; Gate 
Length is not settable in 
FFT sweeps
The sweep time for FFT sweeps is set by the calculations. So 
sweep time settings cannot be adjusted.
–221 Settings conflict; Gate 
Method is not compatible 
with current Sweep Type 
setting
If the Gate is On and you have the FFT Sweep Type manually 
selected, then the Gate Method cannot be selected.
–221 Settings conflict; Gate not 
available with external 
Tracking Source
The Gate functions are unavailable when Source Mode is 
Tracking with an external source. This is because the Gate 
circuitry is used to sync the external source.
–221 Settings conflict; Gate not 
available with Tracking 
Generator
If the Source Type is Tracking Generator, the Gate circuitry is 
used for TG sync and is not available for gating
–221 Settings conflict; Gated FFT 
is not available while Sweep 
Type is set to Swept
The gated FFT function is not available if you have selected 
the swept type of sweep. You must be in the FFT sweep type.
–221 Settings conflict; Gated LO 
is not available while Sweep 
Type is set to FFT
The FFT sweep type moves the LO frequency in steps. So the 
gated LO function is not available if you have selected FFT 
sweep.
–221 Settings conflict; Gated 
Video is not available while 
Sweep Type is set to FFT
The gated video function is not available if you have selected 
the FFT sweep type.

RBW for demod. Change RBW
–221 Settings conflict; Ind I/Q 
is not available for this 
measurement
The Independent I and Q setting is not available for the 
current measurement. Only some measurements (initially, 
only VXA) support this setting.
–221 Settings conflict; Invalid 
trace number
The subopcode used to specify the trace number is invalid 
for this measurement or query
–221 Settings conflict; Knob is 
not available to modify this 
function
You should select a specific value for this function. So 
scrolling through values with the knob is not allowed.
–221 Settings conflict; LO Phase 
Noise Adj not available
For instruments without the Dual-Loop LO, this feature is not 
available
