WSV
The WSV command specifies the staircase sweep voltage source (synchronous
sweep source) that will be synchronized with the staircase sweep voltage source
(primary sweep source) set by the WV command, or the pulsed sweep voltage
source (primary sweep source) set by the PWV 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 WV or PWV command that clears the
WSV command setting. The WI and PWI command also clears the WSV setting.
WSV chnum,range,start,stop[,Icomp[,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 voltage output. Integer
expression. See
The E5260/E5270 usually uses the minimum range that covers both
start and stop values to force the staircase sweep voltage. However, if
you set Pcomp and if the following formulas are true, the E5260/E5270
changes the output range dynamically (20 V range or above). Range
changing may cause 0 V output in a moment. For the limited auto
ranging, the instrument never uses the range less than the specified
range.
•
Icomp > maximum current for the output range
•
Pcomp/output voltage > maximum current for the output range
start, stop : Start or stop voltage (in V). Numeric expression. See
page
4-14. 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
WV or PWV command.
0 to ±100, or 0 to ±200 for E5280B/E5290A
Icomp :
Current compliance (in A). Numeric expression. See
page
4-14. If you do not set Icomp, the previous value is used.
Compliance polarity is automatically set to the same polarity as the
output value, regardless of the specified Icomp. If the output value is 0,
the compliance polarity is positive.
