Description

Use this command to set the expected load impedance of the device

 

under test at the OUTPUT connectors. If you have a non-50 Ω load, the

 

output levels at the device under test will not be the levels you program

 

or set via the front panel unless you set the expected load using this

 

command.

 

Example

To set the expected load impedance:

 

 

:OUTP:IMP:EXT 47.6OHM

Set load impedance at OUTPUT to 47.6 Ω
