SCPI Instrument Command List
Value coupling
Range coupling Offset
Description Use this command to program the amplitude current of the OUTPUT
signal. Note that to set the OUTPUT levels in terms of current, you first
have to execute the
[:SOURce]:HOLD CURRent
command to enable the
[:SOUR
CE
]:CURR
ENT
subsystem.
The available current range is limited by the combination of:
• Specified Voltage limits
• Actual OUTPUT Impedance setting
:OUTPut:IMPedance
• Actual Expected Load impedance setting:
:OUTPut:IMPedance:EXTernal
Example To program the amplitude current of the output signal:
Command :CURR[1]:OFFSet
