Single or parallel BER measurements with ease
Bit error rate measurement testing is simple with the intuitive control screens. The base
software package is free of charge and can perform single-channel BER, multi-channel
BER with an unlimited number of channels, and bathtub measurements.
Need to make a change in the setup after you have started a test? No problem.
Measurements can be stopped at any point and reset to correct set up errors without
needing to wait for the preset time or bit count to be achieved.

Bar graphs provide quick indication of relative BER results during testing of multi-lane
devices. Users can instantly spot a problem in a single lane without needing to look for
outliers in a table of BER numbers.
