5 Example Hardware Test Setup
In order to test the functionality of the DS280MB810EVM, connect TXP0 and TXN0 with MXP cable
assemblies to DC blocking capacitors and a Keysight DCA-x Oscilloscope or equivalent (50
Ω terminated).
Connect the data source, high speed BERT or other device with MXP cable assemblies to RXP0 and
RXN0. Add input and output channels as desired to emulate a system topology. Use the Jitter/Noise and
Eye/Mask functions on the Oscilloscope to view the output. The test set up can be seen below in
Figure 12 .
