PLSDIV TIS Commands
Command Reference
PlsdivSetTransTime
This command changes the pulse transition time of the gate voltage. This change is
effective after the PlsdivForceVg command is executed and until the next
PlsdivSetTransTime command or the PlsdivUninit command is executed. This
command execution is optional.
The transition time is defined as the time from the pulse level 10 % point to the 90 %
point. See
Figure 6-6 .
Remarks
Changing this value may cause measurement errors.

String. However, this command does not return any output parameter.
Write String
This command needs the following input parameter.
trans_time Transition time, in second. Numeric value, 2 ns to 200 ms. This
value must be less than half of the
pulse_width parameter value
set to the PlsdivSetPulseWidth command.
For the 81101A, minimum value is 5 ns.
For the 81150A, minimum value is 2.5 ns when the following
conditions are satisfied, or 7.5 ns.
• Pulse amplitude is 2.5 V or less.
• Both pulse base and top are within

2.5 V.
Response
Status code. Numeric value. To read the error message, use PlsdivErrorMessage. If
no error is detected by this command execution, 0 is returned.
PlsdivSetVgLevel
This command sets the pulse level and polarity of the gate voltage.
Remarks
Check the pulse waveform on the oscilloscope screen, and adjust the gate pulse level
so that the gate pulse and the drain pulse can be monitored.
