During a jitter tolerance compliance test, jitter with the specified jitter
amplitude is sequentially applied at a number of frequency points in the
frequency range of interest.
The receiver checks for transmission errors and measures the bit error
rate.
The graphical display shows the results.
A green circle indicates that the BER at this point did not exceed the
target BER. A red cross indicates that the BER at this point exceeded
the target BER. If this happens, the test is marked as “failed”.
A table below the graph provides details about the measurement
conditions like date/time, data pattern, bit rate, and added jitter
components.
The measurement results for each point can also be exported as a
numerical list in text format.
The maximum jitter amplitude the Serial BERT can generate is also
frequency dependent, as illustrated below.
