WSI
The WSI command specifies the staircase sweep current source (synchronous sweep
source) that will be synchronized with the staircase sweep current source (primary
sweep source) set by the WI command, or the pulsed sweep current source (primary
sweep source) set by the PWI command.
Available for the staircase sweep (MM 2), pulsed sweep (MM 4), or staircase sweep
with pulsed bias (MM5) measurement.
This command must be entered after the WI or PWI command that clears the WSI
command setting. The WV and PWV command also clears the WSI setting.
WSI chnum,range,start,stop[,Vcomp[,Pcomp]]
chnum :
Synchronous 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
range :
Ranging type for synchronous sweep current output. Integer
expression. See
For the linear sweep, the E5260/E5270 uses the minimum range that
covers both start and stop values to force the staircase sweep current.
For the log sweep, the E5260/E5270 uses the minimum range that
covers the output value, and changes the output range dynamically.
Sweep mode, linear or log, is set by the WI or PWI command.
For the limited auto ranging, the instrument never uses the range less
than the specified range.
start, stop : Start or stop current (in A). Numeric expression. See
page
4-15. start and stop must have the same polarity for log sweep.
Sweep mode, linear or log, and the number of sweep steps are set by the
WI or PWI command.
0 to ±0.1, 0 to ±0.2 for E5291A, or 0 to ±1 for E5280B/E5290A
Vcomp :
Voltage compliance (in V). Numeric expression. See
page
4-15. If you do not set Vcomp, the previous value is used.
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 compliance polarity is positive.
