–221 Settings conflict; Log Scale 
Type is not available with 
Demod View
The logarithmic x-axis scales are not available when you 
have the demod view turned on.
–221 Settings conflict; Log Scale 
Type is only available in 
swept measurement
Logarithmic scaling can be used when making a swept SA 
measurement. It is not available in the SA measurement 
when you are using FFT sweeps.
–221 Settings conflict; Marker 1 
Trace Update=off turns off 
Signal Track
Signal Track not available unless the trace containing Marker 
1 is updating 
–221 Settings conflict; Marker 
cannot be relative to itself
A marker must be set relative to another marker, not to 
itself.
–221 Settings conflict; Marker 
Count is not available when 
Gate on
The marker count function cannot be used while you have 
gating turned on.
–221 Settings conflict; Marker 
Function is not available 
for a Fixed marker
If a Marker is a Fixed type marker, the marker's value does 
not change from when it first became fixed. You cannot turn 
on or change a Marker Function because there is no ongoing 
measurement data to use for the marker function 
calculation.
–221 Settings conflict; Marker 
type must be delta
MkrΔ->Span and MkrΔ->CF require that the selected 
marker be a delta marker.
–221 Settings conflict; Marker-> 
function is not available in 
zero span
Most of the “Marker To” functions are not available if you are 
in zero span (span = 0 Hz, or time domain). So you cannot 
send the commands for these functions.
–221 Settings conflict; Mask 
unavailable for current 
Span. Increase to display 
mask.
The current span setting is either narrower than the mask 
width or so wide that there are too few display points to 
allow the mask to be drawn. Increase or decrease the span 
to display the mask.
–221 Settings conflict; Meas Type 
was changed to Examine for 
Exp Avg Mode.
Average Mode has been changed to Exponential. Full Meas 
Type is not available for Exponential Average Mode therefore 
Meas Type has been changed to Examine.
–221 Settings conflict; Meas Type 
was changed to Full for 
Repeat Avg Mode
Average Mode has been changed to Repeat. Examine Meas 
Type is not available for Repeat Average Mode therefore 
Meas Type has been changed to Full.
–221 Settings Conflict; 
MinPts/RBW limit not met
–221 Settings conflict; Mkr -> CF 
is not available when the 
x-axis is time domain
The marker to center frequency functionality does not work 
when the x-axis is in the time domain.
–221 Settings conflict; MS gain 
is not available in this 
Mode
Mobile Station gain correction is not available in some 
Modes, or in some measurements (for example, the SA 
measurement).
