Setting up the Instrument
Setting up the Error Detector
The next step is to set up the error detector’s inputs.
Defining the Clock
Press the
ED Setup
button
to switch to the error
detector setup.
Set the
Active Input.
In our
case, we choose
Normal
because we are testing a
cable that is connected to
the data input port.
Set the
Input Range
so that
it covers both the high and low
voltage levels of the data signal.
Enter the termination voltage
that matches the output
termination of the DUT, in our
case equal to the pattern
generator’s data output.

We have to make sure that the error detector
uses the clock from the pattern generator:
