Evaluating Results

The Serial BERT offers several different kinds of tests that can be run:

Instantaneous Measurements

This type of measurements is used to monitor the instantaneous "BER" / "8B/

10B Comparison" / "Bit Comparison without PCIe3 SKPOS" / "Bit Comparison

without USB3.1 SKPOS" during measurement setup, experiments, and

adjustments.

Accumulated Measurements

This type of measurements is used to measure and log error performance over

time. Also, you can capture the location of bit errors for further analysis.

Eye Measurements

This type of measurements is used to measure the eye height and width of the

incoming data signal at specific alignment BER thresholds. This information is

displayed on a representation of an eye diagram.

With instantaneous measurements, you can directly view the current "BER" /

"8B/10B Comparison" / "Bit Comparison without PCIe3 SKPOS" / "Bit

Comparison without USB3.1 SKPOS" results on the screen.

The "8B/10B Comparison" includes the following measurements:

Symbol Error Ratio (SER)
