Command Reference
PI
Parameters chnum : MFCMU source channel number. Integer expression. 1 to 10 or 101 to
1001. See Table 4-1 on page 4-16.
base,
pulse: Pulse base voltage or pulse peak voltage (in V). Numeric expression.
0 (initial setting) to ± 100 V.
With the SCUU, the source module is automatically selected by the
setting value. The MFCMU is used if the base and pulse values are
below ± 25 V (setting resolution: 0.001 V), or the SMU is used if they
are greater than ± 25 V (setting resolution: 0.005 V).
The SMU will operate with the 100 V limited auto ranging and 20 mA
compliance settings.
Example
Statements
OUTPUT @B1500;"PTDCV 1,0.01"
OUTPUT @B1500;"PDCV 9,0,1"
PI
The PI command specifies the pulse current source and its parameters. This
command also clears, and is cleared by, the PV command setting.
To set the timing of output pulse and measurement, use the PT and AIT2 commands.
In the staircase sweep with pulsed bias measurement mode (set by the MM 5
command), the pulsed bias output will be synchronized with the staircase sweep
outputs set by the WI or WV command.
If Vcomp value is greater than the allowable voltage for the interlock open
condition, the interlock circuit must be shorted.

Parameters chnum : SMU pulsed source channel number. Integer expression. 1 to 10 or 101
to 1001. See Table 4-1 on page 4-16.
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 4-22.
