SCPI Instrument Command List

Range coupling Amplitude

Description Use this command to program the offset 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

Example To program the offset current of the output signal:

Command :CURR[1]:HIGH

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

Form Set & Query

Parameter Numeric

Parameter suffix A with engineering prefixes.

Value coupling

Range coupling Low level

*RST value +10 mA (50 Ω into 50 Ω)

Specified Limits 10 V Output (from high Z into short): –396 mA to 400 mA typical

3.8 V (from 50 Ω into short): –82 mA to 152 mA typical

Description Use this command to program the high level current of the OUTPUT

signal. Note that to set the OUTPUT levels in terms of current, you first

:HOLD CURR

:CURR:OFF 50MA

Enable CURRENT subsystem

Set OUTPUT offset to 50 mA

Amplitude = High – Low

Offset = High – Low
