Command Reference
Command Reference
WNX
The WNX command specifies the staircase sweep source (synchronous sweep
source) that will be synchronized with the staircase sweep source (primary sweep
source) set by the WI or WV command.
You can use the maximum of eight sweep sources. There is no restrictions for the
output mode (voltage or current) of the sweep sources.
Execution
Conditions
Available only for the multi channel sweep measurement (MM 16).
This command must be entered after the WI or WV command that clears the WNX
command setting.
Syntax
WNX N , chnum , mode , range , start , stop [, comp [, Pcomp ]]
Parameters
N : Sweep source number. Integer expression. 2 to 8. Sweep sources start
output simultaneously or in number order. See Remarks below.
chnum : 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
Table 4-1 on page 4-9 .
mode : Sweep source type. Integer expression. 1 or 2.
1: Voltage sweep source.
2: Current sweep source.
Sweep mode, linear or log, is set by the WI or WV command.
range : Ranging type for synchronous sweep output. Integer expression.
• For voltage source ( mode =1): See Table 4-4 on page 4-13 .
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.
• comp > maximum current for the output range
• Pcomp /output value > maximum current for the output range
