Cal Invalid: meas freq
pt(s) > 3.6GHz are >
50MHz from existing Cal
pts
When freq points being measured are above 3.6 GHz and a calibration has been
successfully performed, and the number of points are changed, the new points are
required to be within 50 MHz of the current cal points or the preselector optimize
frequencies become inaccurate and the whole cal needs to be invalidated.
Interpolation of the cal can only be performed if the new freq points are within 50
MHz of the cal points. To overcome this problem, change the number of freq points
back to match cal points or perform another user cal
Carrier power is too low
for optimum dynamic
range.
For better dynamic range, transmit band spur measurements require >10dBm
signal power at the RF input port
Connecting to source… The External Signal Generator is being interrogated via SCPI, to see whether it is
suitable for the instrument to control. Please wait until complete before pressing
any buttons
Demod Time is not
available in Zero Span
The Demod Time function is not available in zero span because in zero span we are
always demodulating
Detector <X> changed due
to physical constraints
You have selected more detectors than the instrument hardware can implement.
An existing detector selection has been changed to allow the current detector
choice to be selected.
<X> indicates the trace number for which the detector was changed
Dynamic range is not
optimum. Set AUTO RF
input.
Exp. Averaging not
available when AUTO
PhNoise is active.
FFT Width is not settable
unless Sweep Type is set
to FFT
You must select the FFT sweep type before you can set the FFT Width
File <filename> saved The file save operation executed successfully
Filter BW function is
only available for
Gaussian filter type
Flattop and CISPR/MIL filters have defined shapes that cannot be altered. Only the
Gaussian filter type allows filter bandwidth definition changes
Fixed LO freq should be
greater than RF Stop freq
The setup frequencies break the rules for a downconverter measurement. The
measurement will still run, but check setup frequencies are correct before
continuing. The LO fixed freq should be greater than the RF freq’s for an LSB or
DSB (for DSB measurements the setup uses LSB values) downconverter setup. Use
the graph icon on the DUT setup form to clarify the setup required
Freq Scale Type=Log is
not available in Zero
Span
Logarithmic scaling cannot be used for time domain sweeps (0 Hz span)
