Results Returned
0 Returns unprocessed I/Q trace data, as a series of comma-separated trace points, in volts. The I
values are listed first in each pair, using the 0 through even-indexed values. The Q values are the
odd-indexed values.
not specified
or n = 1
Returns comma-separated scalar results, in the following order:
PM Deviation (rad or deg, depending on the setting of Display Unit)
PM Deviation Ratio (–999 in Normal mode, Ratio: dB or % depending on Ratio Mode setting)
PM Ratio Reference Deviation (rad or deg, depending on the setting of Display Unit)
Modulation Rate (Hz)
Modulation Distortion (%)
Modulation SINAD (dB)
Sample Time (seconds) is a floating point number representing the time between samples when
querying the demod trace (n=2)
Number of samples is the number of data points in the demod trace. It is used when querying the
demod trace (n=2).
2 Return demodulated waveform vs. time data, as a series of comma-separated trace points. The result
is a series of real numbers in Rad
