Lpbk Tool Button (Loopback Tool)

The Loopback Tool provides the capability of looping back the Ethernet
frames/packets that are received on the loopback tool port.

Pressing the Lpbk Tool button opens the Loopback Tool pop-up and
powers up the port unused by the main test application (it does not start
looping back the frames yet). The Loopback Tool starts looping back the
Ethernet frames/packets that are received when pressing on the Loopback
button from the Loopback Tool tab.

Note: The Lpbk Tool button is available when the main test application is any

Ethernet test application at the exception of Through mode.

Note: The Loopback Tool is independent from the main test Start/Stop, Reset

and Test Timer.

Note: Enabling/disabling the Laser control affects both the main test application

and the Loopback Tool when applicable (if both test and tool are using an
optical port).
