Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual Section 16: SCPI Command Reference
Configure and control limit tests
COMPliance:FAIL <name>
:CALCulate7:LIMit[1]:COMPliance:FAIL <name>Set channel 1 compliance fail
mode
:CALCulate7:LIMit2:COMPliance:FAIL <name>Set channel 2 compliance fail
mode
Parameters <name> = IN Fail Limit 1/2 test when instrument goes into
compliance
OUT Fail Limit 1/2 test when instrument comes out of
compliance
Query :FAIL? Query when Limit 1/2 test failure occurs
Description These commands are used to specify the condition that will cause the Limit 1 and
Limit 2 tests to fail. With IN specified, the test will fail when the Model 6482 goes
into compliance (fixed 20 mA current limit for each voltage source). With OUT
specified, the test will fail when the Model 6482 comes out of compliance.
[:DATA] <n>
:CALCulate7:LIMitx:LOWer[:DATA] <n>Specify lower Limit x (x = 3-6)
:CALCulate7:LIMitx:UPPer[:DATA] <n>Specify upper Limit x (x = 3-6)
Parameters <n> = -9.999999e20 to Specify limit value
9.999999e20
DEFault Set specified lower limit to -1
Set specified upper limit to 1
MINimum Set specified limit to -9.999999e20
MAXimum Set specified limit to +9.999999e20
Query :UPPer? Query specified upper limit
:UPPer? DEFault Query *RST default upper limit
:UPPer? MINimum Query lowest allowable upper limit
:UPPer? MAXimum Query largest allowable upper limit
:LOWer? Query specified lower limit
:LOWer? DEFault Query *RST default lower limit
:LOWer? MINimum Query lowest allowable lower limit
:LOWer? MAXimum Query largest allowable lower limit
Description These commands are used to set the upper and lower limits for the Limit 3
through Limit 6 tests (software limits).
STATe <b>
:CALCulate7:LIMit[1]:STATe <b>Control Limit 1 (channel 1) test
:CALCulate7:LIMit2:STATe <b> Control Limit 2 (channel 2) test
:CALCulate7:LIMitx:STATe <b> Control Limit x test (x = 3-6)
Parameters <b> = 1 or ON Enable specified limit test
0 or OFF Disable specified limit test
Query :STATe? Query state of specified limit test
Description These commands are used to enable or disable Limit 1 through Limit 6, tests.
Limit 1 and Limit 2 are the compliance limit tests for channel 1 and channel 2
respectively, while Limit 3 through Limit 6 are the software limit tests. Any limit test
not enabled is simply not performed.
