Command Reference
Command Reference
DI
The DI command forces current from the specified channel.
Execution
Conditions
The CN command has been executed for the specified channel.
If the voltage compliance is greater than ±42 V, the interlock circuit must be shorted.
Syntax DI chnum,irange,current[,Vcomp[,comp_polarity[,vrange]]]
Parameters chnum : 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 current output. Integer expression. The output range
will be set to the minimum range that covers current value. For the
limited auto ranging, the instrument never uses the range less than the
specified range. See
Table 4-5 on page 4-13.
current : Output current value (in A). Numeric expression. See Table 4-7 on
page 4-15.
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 you do not specify this parameter, Vcomp is set to the
previous setting.
comp_
polarity :
Polarity of voltage compliance. Integer expression.
0: Auto mode (default setting). The compliance polarity is
automatically set to the same polarity as current, regardless of the
specified Vcomp. If
current=0 A, the polarity is set to positive.
1: Manual mode. Uses the polarity of Vcomp you specified.
vrange : Voltage compliance ranging type. Integer expression. The compliance
range will be set to the minimum range that covers Vcomp value. For
the limited auto ranging, the instrument never uses the range less than
the specified range. See
Table 4-4 on page 4-13.
