PWI
The PWI command specifies the pulsed sweep current source and its parameters.
This command clears the settings of the PWV, WSV and WSI commands.
The settings specified by this command are cleared by the PWV command.
Measurement channel performs measurement so that the pulse width and pulse
period are kept. The integration time is automatically set by the instrument, and you
cannot change. For the Keysight E5270B, note that the high-resolution ADC cannot
be used for the pulsed measurements. The AAD/AIT/AV/WT command settings are
ignored.
PWI chnum,mode,range,base,start,stop,step[,Vcomp]
chnum :
Pulsed sweep source channel number. The value must be slot number
where the module has been installed. Integer expression. 1 to 8 (1 and 5
are not available for HPSMU). See
mode :
Sweep mode. Integer expression. 1 or 3.
1: Linear sweep (single stair, start to stop.)
3: Linear sweep (double stair, start to stop to start.)
range :
Ranging type for pulsed current sweep. Integer expression. The output
range will be set to the minimum range that covers base, start, and stop
values. For the limited auto ranging, the instrument never uses the
range less than the specified range. See
base, start,
stop :
Pulse base, start, or stop current (in A). Numeric expression. See
4-7 on page
0 to ±0.1, 0 to ±0.2 for E5291A, or 0 to ±1 for E5280B/E5290A
step :
Number of steps for pulsed sweep. Numeric expression. 1 to 1001.
The E5260/E5270 can store approximately 16000 measurement data in
ASCII format with header without source data, or approximately 64000
measurement data in binary format.
Vcomp :
Voltage compliance (in V). Numeric expression. See
page
4-15. If you do not specify Vcomp, the previous value is set.
Compliance polarity is automatically set to the same polarity as the
output value, regardless of the specified Vcomp. If the output value is 0,
the polarity is set to positive.
