GPIB/RS232 Operation Description (IEEE-488.2)
5-23
Example: Input command “SAFE:STEP2:AC:TIME:FALL?”
Return message “3.000000E+00”
Description: Return message “3.000000E+00” means the time required for the
voltage to fall to 0 in STEP 2 is 3.0sec..
[:SOURce]:SAFEty:STEP<n>:AC:CHANnel[:HIGH] < channel list >
This command sets the high scan channels for the selected step. The <channel
list> format is: (@SN(C1, C2, C3)). SN is the scan box number; C1, C2, and C3 are
the channel numbers.
Example: Input command “SAFE:STEP2:AC:CHAN(@2(1,2))”
Description: This command sets the high scan channel in STEP 2 to BOX 2
channel 1 and 2 HIGH output.
Example: Input command “SAFE:STEP2:AC:CHAN(@2(0))”
Description: This command means the BOX 2 high scan channel in STEP 2 is set
to OFF.
[:SOURce]:SAFEty:STEP<n>:AC:CHANnel[:HIGH]?
This command queries the high scan channels for the selected step.
Example: Input command “SAFE:STEP2:AC:CHAN?”
Return message “(@2(1,2))”
Description: Return message “(@2(1,2))” means the high scan channel in STEP 2
is set to BOX 2 channel 1 and 2 HIGH output.
[:SOURce]:SAFEty:STEP<n>:AC:CHANnel:LOW < channel list >
This command sets the low scan channels for the selected step (RTN/LOW).
Example: Input command “SAFE:STEP2:AC:CHAN:LOW (@2(2,4))”
Description: This command means the low scan channels in STEP 2 are set to
BOX 2 channel 2 and 4 LOW output.
Example: Input command “SAFE:STEP2:AC:CHAN:LOW (@2(0))”
Description: This command sets the low scan channel in STEP 2 to O FF.
[:SOURce]:SAFEty:STEP<n>:AC:CHANnel:LOW?
This command queries the low scan channels for the selected step.
Example: Input command “SAFE: STEP2: AC: CHAN: LOW?”
Return message “(@2(2,4))”
Description: Return message “(@2(2,4))” means the low scan channels in STEP 2
are BOX 1 channel 2 and 4 LOW output.
[:SOURce]:SAFEty:STEP<n>:DC:CURRent:OFFSet <numeric value>
This command sets the Offset value of the DC withstand test for the selected step.
Parameter <numeric value>: The Offset value of the DC withstand test in
Amperes (A).
Range: The Offset range is 0.0000000~0.0002999 when the High Limit range is
from 0.1uA to 299.9uA.
The Offset range is 0.000000~0.002999 when the High Limit range is from
0.3mA to 2.999mA.
The Offset range is 0.000000~0.01200 when the High Limit range is from
3mA to 12mA.
Example: Input command “SAFE:STEP2:DC:CURR:OFFS 0.00001”
Description: This command sets the Offset value of the DC withstand test in Step 2
to 10uA.
