[:SOURce<hw>]:BB:ARBitrary:CFR:ALGorithm <ArbCfrAlgorithm>
Displays the algorithm used for the crest factor reduction. The "Clipping and filtering"
algorithm performs a hard clipping. It is followed by a low pass filtering of the result in
an iterative manner until the target crest factor is reached. You can define the settings
of the filter that is used for the calculation.
Parameters:
<ArbCfrAlgorithm>
Example:
Manual operation:
[:SOURce<hw>]:BB:ARBitrary:CFR:CSPacing <ArbCfrChanSpac>
Sets the channel spacing, if
SIMPle.
Parameters:
<ArbCfrChanSpac>
Example:
Manual operation:
[:SOURce<hw>]:BB:ARBitrary:CFR:DCFDelta <ArbCfrDCFDelta>
Sets the value difference by which you want to change your crest factor.
Parameters:
<ArbCfrDCFDelta>
Example:
Manual operation:
[:SOURce<hw>]:BB:ARBitrary:CFR:FILTer <ArbCfrFilterMod>
Selects which filter mode is used for the filtering.
Parameters:
<ArbCfrFilterMod>
