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:
Return the measured modulation rate (Hz).
Modulation Rate Ratio (–999 in Normal mode, Ratio: dB or % depending on Ratio Mode setting)
Ratio Reference Frequency (Hz)
Return demodulated result(% for AM, Hz for FM, and rad for PM)
Return modulation distortion(%)
Return modulation sinad(dB)
