Purpose

Keysight N5990A MIPI M-PHY Receiver Test User Guide
This calibration is available for all hardware configurations.
Figure 73 Eye Opening Calibration with Jitter
The purpose of this calibration is to fine-tune the horizontal jitter
component and the vertical amplitude to reach a target eye mask.
According to the specification this eye mask must have a width of 0.52UI,
which corresponds to a BER of 1E-6, and an amplitude of 43mV.
This calibration is run once at each selected HS data rate (see
For spec 4.1, this calibration is only mandatory for B-series (for A-series,
the procedure is shown in the test tree as informative).
