PLSDIV TIS Commands

PlsdivSetSmoothing

This command needs the following input parameters in this sequence.
sampling_rate Sampling rate. Numeric value, 0 (auto), 1 to 20 G [times/sec].
It is difficult to find the optimum value. Set sampling_rate=0
for an easy setup.
sampling_num Total number of sampling. Numeric value, 0 (auto), 16 to
262144.
Status code. Numeric value. To read the error message, use PlsdivErrorMessage. If
no error is detected by this command execution, 0 is returned.

This command needs the following input parameters in this sequence.
ch Oscilloscope channel. Numeric value, 0 (channel for gate) or
1 (channel for drain).
smooth_stat Smoothing function on or off. Numeric value, 0 (off) or 1 (on).
smooth_num Number of measurement points used for smoothing. Numeric
value, 3 to 4001. The value must be less than the sampling_num
parameter value set to the PlsdivSetSampling command.
Status code. Numeric value. To read the error message, use PlsdivErrorMessage. If
no error is detected by this command execution, 0 is returned.
The smoothing function averages the time-series data to reduce variation caused by
high-frequency component.
Set appropriate smooth_num value while monitoring the waveform. Too much
smooth_num value will lose the waveform edges, which disturbs accurate results.
