User guide

The error ratio during periods of constant errors was 0.00195313. This corresponds
to 1.953E-3.
Random Errors
Random errors may have been caused by a noisy waveform. Noise can be caused
by bad cables or connectors.
The output of your device may contain errors due to noise, although a noisy
waveform is not present at the output. The noise may originate somewhere else
within your device or system, causing random bit errors to be passed on to other
components. Therefore, your device may have a good output waveform and still
transmit random bit errors.
