6-28
[:SOURce]:SAFety:STEP<n>:IR:RANGe[:LOWer] < numeric value >
It selects the lower current range for measurement based on the inputted current. The
unit is Ampere (A).
Range: 0.000000001~0.005 for 19020, 0.000000001~0.0035 for 19022.
Example: Input the command SAF:STEP3:IR:RANG:LOW 0.0003.
Description: It means the current for IR measurement in the host STEP 3 is 300uA,
so the lower current range selected for IR measurement is 300uA.
[:SOURce]:SAFety:STEP<n>:IR:RANGe[:LOWer]?
It queries the lower range set.
Example: Input the command SAF:STEP3:IR:RANG:LOW?
The tester returns 3.000000E-04.
Description: The returned 3.000000E-04 means the range set for the host STEP 3
is 300uA.
[:SOURce]:SAFety:STEP<n>:IR:RANGe: AUTO < boolean > | ON | OFF
It sets if IR range switches to AUTO. Parameter ON or 1 means AUTO while OFF or 0
means AUTO is disabled.
Note
When AUTO is not set, giving the parameter OFF will remain the original set
range. When AUTO is set, giving the parameter OFF will set the range to 5mA.
Example: Input the command SAF:STEP3:IR:RANG:AUTO ON.
Description: It means the current range for the host STEP 3 IR measurement is
AUTO.
[:SOURce]:SAFety:STEP<n>:IR:RANGe:AUTO?
It queries if IR range switches to AUTO. 1 means it is set to AUTO while 0 means AUTO
is disabled.
Example: Input the command SAF:STEP3:IR:AUTO?
The tester returns 1.
Description: The returned 1 means the range is set to AUTO for the host STEP 3.
[:SOURce]:SAFety:STEP<n>:IR:TIME:DWELl < numeric value >
It sets the dwell time required for the selected STEP. The unit is second (s).
Range: 0 or 0.1~999.9, 0 is OFF.
Example: Input the command SAF:STEP2:IR:TIME:DWEL 2.5.
Description: It means the dewell time set for host STEP 2 is 2.5 sec.
[:SOURce]:SAFety:STEP<n>:IR:TIME:DWELl?
It queries the dwell time required for the selected STEP.
Example: Input the command SAFE:STEP2:IR:TIME:DWEL?
The tester returns 2.500000E+00.
Description: The returned 2.500000E+00 indicate the dwell time set for STEP 2 is
2.5 sec.
[:SOURce]:SAFety:STEP<n>:IR:TIME:FALL < numeric value >
It sets the time required for set voltage to fall to 0 for selected STEP. The unit is second
(s).
