To select the termination for the error detector:
NO TE
Prerequisite: You must know the termination voltage of the data signal
that your DUT sends to the error detector.
1 In the ED Setup menu, press Sampling Point Setup to access the
Sampling Point Setup window.
2 Click the Edit button. This opens the ED Input Setup dialog.
3 In the Termination field, enter the termination voltage that is
appropriate for the incoming data signal.
You can use the front panel knob or the numeric keypad to enter the
value.
Selecting the wrong termination may damage your device.
4 Select the Data Inverted checkbox if your device inverts data.
You can now physically connect the DUT to the error detector.
Data Input Setup – Reference
The ED Input Setup dialog is accessed from the Sampling Point Setup
window. It is used to set up the error detector's data input port:
Input
The selection in this list defines how the signals arriving at the Data In
and Data In connectors are interpreted. The following options are
available:
• Normal
In normal mode, only the Data In port receives the data signal, the
Data In port is inactive.
• Complement
In complement mode, only the Data In port receives the data signal,
the Data In port is inactive.
