Using the N4917CPCA Software
Testing a CPRI Interface
Once the Stressed Eye Calibration is complete, remove the optical fiber
connection from the DCA input and connect it to the input of the CPRI
interface device under test. Exact connection details and setup depend on
the system architecture being tested and are therefore not covered in
detail in this guide.
CPRI Fronthaul Radio Equipment Input Test
Typically the calibrated stressed eye signal is connected to the input of the
CPRI radio equipment lane under test, and either BER or Clock frequency
stability and noise measurements are performed.
