5-19
[:SOURce]:SAFEty:STEP<n>:GB:LIMit:LOW
This command sets the grounding resistance low limit value in Ohms for the
selected step.
Range : 0.0001 ~0.51 (the low limit value of grounding resistance should be
≤ the high limit value)
Example : Input command “SAFE:STEP1:GB:LIM:LOW 0.01”
Description : This command sets the step 1 grounding resistance low limit
value to 0.01 ohm.
[:SOURce]:SAFEty:STEP<n>:GB:LIMit:LOW?
This command queries the grounding resistance low limit value for the selected
step.
Example : Input command “SAFE:STEP:GB:LIM:LOW?”
Return message “+1.000000E-02”
Description : Return message “+1.000000E-02” means the grounding
resistance low limit value is 0.01 ohm.
[:SOURce]:SAFEty:STEP<n>:GB:TIME[:TEST] < numeric value >
This command sets the test time in seconds for the selected step.
Range : 0 or 0.3~999.0 (0=CONTINUOUS)
Example : Input command “SAFE:STEP1:GB:TIME 0.5”
Description : This command sets the step 1 test time to 0.5 seconds.
[:SOURce]:SAFEty:STEP<n>:GB:TIME[:TEST]?
This command queries the test time for the selected step.
Example : Input command “SAFE:STEP:GB:TIME?”
Return message “+5.000000E-01”
Description : Return message “+5.000000E-01” means the test time is 0.5
seconds.
[:SOURce]:SAFEty:STEP<n>:GB:TPORt < boolean > | ON | OFF
This command enables or disables the twin port function (ON or OFF).
Example : Input command “SAFE:STEP1:GB:TROP ON”
Description : This command sets the step 1 twin port function ON.
[:SOURce]:SAFEty:STEP<n>:GB:TPORt?
This command queries the twin port function for the selected step.
Example : Input command “SAFE:STEP:GB:TROP?”
Return message “1”
Description : Return message “1” means the step 1 twin port output function is
ON.
[:SOURce]:SAFEty:STEP<n>:GB: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:STEP1:GB:CHAN(@2(1,2))”
Description : This command sets the high scan channel in STEP 1 to BOX 2
channel 1 and 2 HIGH output.
Example : Input command “SAFE:STEP1:GB:CHAN(@2(0))”
Description : This command means the BOX 2 high scan channel in STEP 1 is
set to OFF.
