Command Reference
Command Reference
PI
The PI command specifies the pulse current source and its parameters. This
command also clears, and is cleared by, the PV command setting.
In the staircase sweep with pulsed bias measurement mode (set by the MM 5
command), the output forced by the PI command synchronized with the staircase
sweep outputs forced by the WI or WV 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.
Syntax PI chnum,irange,base,pulse[,Vcomp]
Parameters chnum : Pulsed 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
Table 4-1 on page 4-9.
irange: Ranging type for pulse current output. Integer expression. The output
range will be set to the minimum range that covers both base and pulse
values. For the limited auto ranging, the instrument never uses the
range less than the specified range. See
Table 4-5 on page 4-13.
base,
pulse
: Pulse base current or pulse peak current (in A). Numeric expression.
See
Table 4-7 on page 4-15. base and pulse must have the same
polarity.
0 to ±0.1, 0 to ±0.2 for E5291A, or 0 to ±1 for E5280B/E5290A
Vcomp: Voltage compliance value (in V). Numeric expression. See Table 4-7 on
page 4-15. If Vcomp is not specified, 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.
