–221 Settings conflict; Span Zoom
is not available in Zero
Span
Span Zoom does not work with a time domain x-axis. You
must select a span greater then 0 Hz.
–221 Settings conflict; Span Zoom
not available when Frequency
Scale Type = Log
The Span Zoom feature cannot be used when the X-axis
scale is logarithmic frequency.
–221 Settings conflict; Step keys
are not available to modify
this function
You should select a specific value for this function. So using
the Up/Down step keys to scroll through values is not
allowed.
–221 Settings conflict; Sweep
Setup only available in
swept measurements
The current measurement uses FFT mode and so does not
use the Sweep Setup menu
–221 Settings conflict; Sweep
Time cannot be auto-coupled
in FFT sweeps
The sweep time for FFT sweeps is set by the calculations. So
sweep time settings cannot be adjusted.
–221 Settings conflict; Sweep
Time cannot be auto-coupled
while in Zero Span
You cannot send the remote command to set the sweep time
to auto while you are in zero span.
–221 Settings conflict; Sweep
Time cannot be set while in
FFT sweeps
The sweep time for FFT sweeps is set by the calculations. It
cannot be manually controlled.
–221 Settings conflict; Swept IF
Gain High not available when
FFT IF Gain = Manual Low
When FFT IF Gain is manually set to Low, you cannot set the
Swept IF Gain to High because that would make the
Reference Level couplings wrong in swept mode.
–221 Settings conflict; Swept LO
not available when freq mode
is Fixed
SCPI only message. The LO Mode cannot be set to Swept
when the freq mode is set to fixed. Change the freq mode
away from fixed, or perform the measurement at several
fixed frequencies.
–221 Settings conflict; Swept
Type=Swept is not available
while in Gated FFT
If you have selected gated FFT then you are using the FFT
sweep type and you cannot select the swept type of
sweeping.
–221 Settings conflict; System
Display Settings, Annotation
is Off
This is an override that turns off many of the annotations.
This is available as a security feature.
–221 Settings conflict; T hot
must be greater than T cold
The Tcold value set under Meas Setup/ENR/Tcold, needs to
be lower than the Thot value currently being set. Tcold is
often taken as the ambient temperature of the noise source.
If using an SNS the Tcold value may be read automatically
before every sweep.
–221 Settings Conflict; The
parameter cannot be changed
in FAST mode
