: For the Add-In Card CEM Rx calibration, a 9.5 dB add-in card budget and 19.75 to 22.75 dB
system budget shall be used in the intended 34 to 37 dB pad-to-pad loss range.
1.
Using 1 ft cables, connect between both the CBB Rx Lane 0 and CBB Variable ISI (Nominal
19.75 to 22.75 dB trace) and between both the CLB Tx Lane 0 and the CLB Variable ISI (Nominal
2.5 dB trace).
2.
Using 1 m cables, connect between both the VNA Ports 1 & 3 and the CBB Variable ISI and
between both the CLB Variable ISI and the VNA Ports 2 & 4.
