GPIB/RS232 Operation Description (IEEE-488.2)
5-29
[:SOURce]:SAFEty:STEP<n>:IR:RANGe[:UPPer]
This command queries set range.
Example: Input command “SAFE:STEP4:IR:RANG?”
Return message “3.000000E-03”
Description: Return message “3.000000E-03” means set range for main STEP 4 is
3mA.
[:SOURce]:SAFEty:STEP<n>:IR:RANGe:LOWer
This command selects the range lower than the current measured according to
current value
users inputted. The unit is ampere (A).
Range: 0~0.01
Example: Input command “SAFE:STEP4:IR:RANG:LOW 0.0003”
Description: This command sets IR measured current value of main STEP 4 to
300uA thus the selected IR range lower than the current measured is
300uA.
[:SOURce]:SAFEty:STEP<n>:IR:RANGe:LOWer?
This command queries set range.
Example: Input command “SAFE:STEP4:IR:RANG?”
Return message “3.000000E-04”
Description: Return message “3.000000E-04” means set range for main STEP 4 is
300uA.
[:SOURce]:SAFEty:STEP<n>:IR:RANGe:AUTO
This command sets if IR range be changed to AUTO.
Set to AUTO when parameter is ON or 1.
Set to disable AUTO when parameter is OFF or 0.
Note: It remains the default setting range when AUTO unset and gives OFF parameter. Set
10mA when the default setting is AUTO and gives OFF parameter.
Example: Input command “SAFE:STEP4:IR:RANG:AUTO ON”
Description: This command sets IR measured current range for main STEP 4 to
AUTO.
[:SOURce]:SAFEty:STEP<n>:IR:RANGe:AUTO?
This command queries if IR range be changed to AUTO.
Set to AUTO when returns 1.
Set to disable AUTO when returns 0.
Example: Input command “SAFE:STEP4:IR:AUTO?”
Return message “1”
Description: Return message “1” means set range for main STEP 4 is AUTO.
[:SOURce]:SAFEty:STEP<n>:IR: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: STEP4: IR:CHAN(@2(1,2))”
Description: This command sets the high scan channels for STEP 4 to BOX 2
channel 1 and 2 HIGH output.
Example: Input command “SAFE: STEP4: IR:CHAN(@2(0))”
Description: This command sets the high channel for STEP 4 to BOX 2 HIGH
