9 Sink Test Calibration Procedure

The following Figure shows the conceptual setup as described in Figure 4-3 of the PHYCTS 1.2b.

Figure 2: PHY CTS 1.2b HBR/HBR2 Conceptual Setup (Figure 4-3 in PHY CTS 1.2b)

The following procedure describes step-by-step how to calibrate the stressed impairments per the PHY

CTS 1.2b. Follow the steps appropriate for HBR2, HBR, and RBR. The detailed example shown is for

HBR2 as specified in Table 4-4 of the PHYCTS 1.2b. Since the lanes on test fixture vary in ISI and cross

talk behavior the calibration steps for ISI, SJ

sweep

and eye opening without and with cross talk have to be

done per lane.
