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:

 

:HOLD CURR

 

 

Enable CURRENT subsystem

 

:CURR:OFF 50MA

 

 

Set OUTPUT offset to 50 mA
