Frequency Sweep Measurements
No data will be returned for this type of measurement, should it be requested, until such time as a
measurement has been previously run.
Running an IQ measurement will not generate results for this type of measurement.
Spectrum Mask
Result data will be returned as 501 measurement 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 will be returned. TRACE1 is used for this measurement results.
Spectrum ACPR
Result data will be returned as 501 measurement 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 will be returned. TRACE1 is used for this measurement results.
TRACe[:DATA]
This command returns all the measured data that relates to the currently selected measurement
type. All results are returned in ASCII format. The returned data depends on the currently
selected measurement type. DISPlay:FORMat is not supported with this command.
The following measurement types are available:
– "IQ Measurements" on page 6.745
– "Constellation vs Symbol" on page 6.745
