Programming Reference
SCPI Instrument Command List
have to execute
[: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 high level current of the output signal:
Command
:CURR[1]:LOW

Specified Limits
10 V Outputs (from high Z into short): –400 mA to 396 mA typical
3.8 V Outputs (from 50
Ω
into short): –84 mA to 150 mA typical
Description
Use this command to program the low level 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 c
ommand to enable
the
[:SOURce]:CURRent
subsystem.
The available current range is limited by the combination of:
:HOLD CURR
:CURR:HIGH 150MA
