Performing an Acquisition
For rough measurements in links with high PMD, you should use a
value between 0.4 and 1 ps. For low PMD measurements, use a value
around 50 ps and at least 100 SOPs. For faster measurements of small
PMD values, use a lower setting, such as 2 ps.
To perform an advanced acquisition:
1. From the main window, under General, select the Advanced
acquisition mode.
