Measurement Algorithms
To set up the oscilloscope for the High Speed Device EL_21, EL_23, EL_25
(Sync-EOPIII-InterPacketII&III) and a High Speed Device EL_22
(InterPacketI&II), follow these steps:
1.
Select the measurement and run the application. The application
automatically sets the oscilloscope parameters (Horizontal, Vertical, and
Trigger) and displays the message, "Press OK when correct waveform is
acquired”. You can see the SOFs on the oscilloscope screen.
2.
If you are not able to acquire the waveform automatically, perform
Autosetup in the oscilloscope to display the SOF.
3.
If your DUT is EL_21, EL_23, EL_25, select the Single Step Set Feature
option from the HS electrical test tool.
4.
If your DUT is EL_22, select the Step button in the HS electrical test tool to
acquire the waveform as shown in the following figure:
