If the device supports FAUX hook the AUX signals on the Wilder plug fixture to the DUTs FAUX signal
using another adapter. Make sure FAUX signals from the DUT are signaling during the next calibration
steps.
4. Turn on all jitter stress impairments ((ISI, RJ, SJ
FIXED
, SJ
SWEEP
, crosstalk, SSC) on the SSG.
a. ISI is achieved with the HW channel in Step 2.
b. In the JBERT-B, select Jitter Output Menu.
ii. Enable the RJ calibrated in9.2.
iii. If testing HBR2, Enable the SJ
FIXED
(PJ 2) calibrated in9.3.1.
iv. Enable the SJ
SWEEP
(PJ 1) at 10MHz with amplitude determined in 9.3.2.
v. Enable SSC with frequency of 33 KHz and 5000ppm with a triangle profile.

9.4.1 Eye Height Calibration without Crosstalk
1. Calibrate the amplitude of the SSG to achieve an EYE Height 150mV at TP3_EQ for HBR and
120.0mV at TP3_EQ without crosstalk for HBR2; with the JMD using the 2
nd
order clock recovery
function described in Section 2.1 of the DP1.2a Standard.
a. In the J-BERT N4903B Jitter > PG Output Menu, Select the data output amplitude
adjustment.
