When the DUT input/output signal is electrical:
Input the output of the PPG in the BERTWave to the DUT, and then
measure the DUT output using the sampling oscilloscope.
1. Connect the DUT input terminal to PPG1
Data
Out/Data Out using
a coaxial cable.
If only one DUT input connector is conveniently available, connect to
the PPG1 Data Out. Also, connect the coaxial terminator included as
a standard accessory to the
Data
Out.
2. With the Option 021, connect the DUT output terminator to A In and
B In on the sampling oscilloscope using a coaxial cable.
If only one DUT output connector is conveniently available, connect
