Programming Reference

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

[:SOURCE]:CURRENT 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

Long [:SOURce]:CURRent[1][:LEVel][:IMMediate]:OFFSet
