Return values:
<ArbCfrOCrestFac> float
Example:
Usage:
Manual operation:
[:SOURce<hw>]:BB:ARBitrary:CFR:PFReq <ArbCfrPassBFreq>
Sets the passband frequency, if
set to ENHanced. Frequency components lower than the passband frequency are
passed through unfiltered.
Parameters:
<ArbCfrPassBFreq> float
Example:
Manual operation:
[:SOURce<hw>]:BB:ARBitrary:CFR:RCFactor?
Queries the resulting crest factor of the waveform after the calculations are completed.
The resulting crest factor is calculated as an average over the whole waveform, includ-
ing any idle periods that might be present in TDD waveforms.
Return values:
<ArbCfrResCreFac> float
Example:
Usage:
Manual operation:
[:SOURce<hw>]:BB:ARBitrary:CFR:SBANdwidth <ArbCfrSignalBw>
Sets the signal bandwidth, if
to SIMPle.
The value of the signal bandwidth should not be higher than the channel spacing
SOURce<hw>]:BB:ARBitrary:CFR:CSPacing).
