Setting Up The Error Detector; Connecting The Dut - Agilent Technologies BERT N4901A Getting Started

Setting up the Instrument

Setting up the Error Detector

The next step is to set up the error detector's inputs.
1
Press the ED Setup button
to switch to the error
detector setup.
2
Set the Active Input. In our
case, we choose Normal
because we are testing a
cable that is connected to
the data input port.

Connecting the DUT

You can now connect the DUT. In our case you
just have to connect the following ports:
Defining the Clock
We have to make sure that the error detector
uses the clock from the pattern generator:
1
Switch to the
Clock Setup.

3
Set the Input Range so that
it covers both the high and low
voltage levels of the data signal.
PG Clock Out
ED Clock In

4
Enter the termination voltage
that matches the output
termination of the DUT, in our
case equal to the pattern
generator's data output.

Select External Clock
Source as the source
for the clock signal.
