channel.
[:SOURce]:SAFety:STEP<n>:AC:CHANnel:PSC P | S | PS, S | C | SC
It sets the scan channel status for selected STEP.
Example: Input the command SAF:STEP1:AC:CHAN:PSC P,S
Description: It means to set the scan channel of STEP 1 to PS.
[:SOURce]:SAFety:STEP<n>:AC:CHANnel:PSC?
It queries the scan channel status for selected STEP.
Example: Input the command SAF:STEP1:AC:CHAN:PSC?
The tester returns P,S.
Description: It means the scan channel of STEP 1 is set to PS.
[:SOURce]:SAFety:STEP<n>:AC[:LEVel] < numeric value >
It sets the voltage required for AC withstand voltage test for selected STEP. The unit is
Volt (V).
Range: The range of 19020 is 50~5000 and the range of 19021 is 50~6000.
Example: Input the command SAF:STEP1:AC 3000.
Description: It means to set the voltage required by AC withstand voltage test for
the host STEP 1 is 3kV.
[:SOURce]:SAFety:STEP<n>:AC[:LEVel]?
It queries the voltage required for AC withstand voltage test for selected STEP.
Example: Input the command SAF:STEP1:AC?
The tester returns 3.000000E+03.
Description: The returned 3.000000E+03 means the voltage required by AC
withstand voltage test for the host STEP 1 is 3kV.
[:SOURce]:SAFety:STEP<n>:AC:LIMit:ARC < numeric value >
It sets the ARC test value for selected STEP. The unit is Ampere (A).
Range: 0 or 0.001~0.020, 0 is OFF.
Example: Input the command SAF:STEP1:AC:LIM:ARC 0.004.
Description: It means the ARC test value in AC Mode for the host STEP 1 is 4mA.
[:SOURce]:SAFety:STEP<n>:AC:LIMit:ARC?
It queries the ARC test value for selected STEP.
Example: Input the command SAF:STEP1:AC:LIM:ARC?
The tester returns 4.000000E-03.
Description: The returned 4.000000E-03 means the ARC test value for the host
STEP 1 is 4mA.
[:SOURce]:SAFety:STEP<n>:AC:LIMit[:HIGH] < numeric value >
It sets the high limit of AC withstand leakage current for selected STEP. The unit is
Ampere (A).
Range: The range of 19020 is 0.000001~0.01 and the range of 19021 is
0.000001~0.008.
