5.16.13 Error vs Preamble
Three traces types are available with this measurement. The basic trace types show
either the minimum, mean or maximum frequency or phase value as measured over
the preamble part of the burst.
Supported data formats (see FORMat[:DATA] on page 176): ASCii|REAL
5.16.14 Frequency Sweep Measurements
Currently, there is only one measurement that is performed in frequency sweep mode.
This is the Spectrum Mask measurement. No data is returned for this measurement,
should it be requested, until such a measurement has been previously run.
Running an IQ measurement does not generate results for this type of measurement.
5.16.14.1 Spectrum Mask
Result data is returned as 625 trace points in floating point format. These trace points
are obtained directly from the base system via the measurement API and the quantity
is therefore a fixed value. Only an array of Y data is returned.
Supported data formats (see FORMat[:DATA] on page 176): ASCii|REAL
TRACE1 Clear write values
TRACE2 Max hold values
