CALCulate:FILTer:FREQuency:TWIDth?
Sets or queries the slope of roll off for the post-acquisition filter. The filter slope
is specified as a ratio of the absolute transition width (in Hz) to Nyquist
frequency defined as 1 / (2 × <sample interval>). A low value for transition
width produces a steep slope for the filter while a large value produces a gradual
slope or roll off. You can also specify :TWIDth in percent.
If you enter too small a value for :TWIDth, the function will generate too many
filter coefficients resulting in an execution error and termination of the filter
process. For more information, refer to the filter discussion in the TVS600 &
TVS600A Series Waveform Analyzers User Manual.
