Calibrating your System for ORL Testing
Calibrating your System for ORL Testing
The current section gives you the information you need to perform an ORL
calibration. This operation measures ORL in the system before testing
DUTs. The results obtained will be used to calculate the ORL specific to the
DUTs.
If you need more details about ORL calibration, see Return Loss
Calibration on page 80.
From the System menu of the main window, select Return Loss
Calibration. The following dialog box is displayed.
The dialog box can be divided into three main parts:
³
A monitoring zone that allows you to verify the power read from the
WRM, in dBm.
³
A connection information section that indicates which switch port the
reference test jumper should be connected to.
³
A section that displays useful instructions about ORL calibration.
