MeasTime
MeasTime defines the data extraction timing (see Figure 5-9 ) which is the timing to
extract the pulsed IV measurement data (gate voltage, drain voltage, and drain
current) from the oscilloscope measurement result (pulse waveform). Initially, this
value is set to 0.5. Changing this value may cause a measurement error. If you
change this value, check the pulse waveform and choose the point where the pulse
voltage is flat and stable.

SmplNum
SmplNum defines the sampling number set to the oscilloscope. Set the value in
order to display the pulse waveform on the oscilloscope screen. A small number will
improve measurement throughput.
Sampling rate of the oscilloscope is set to the value automatically calculated from
the specified pulse width and the specified sampling number.
