Stressed receiver sensitivity test set-up with C-BERT 2961-1.

The The C-BERT 2861-2 is the ideal test instrument for optical receiver sensitivity test

The C-BERT 2861-2 enables the calibration of the optical Transmitter signal for stressed receiver sensitivity test acc. IEEE.
With the built-in linear optical receiver the OMA and the contour amplitude at BER=2.5E-4 is measured to calculate the VECP (vertical eye closure penalty). The amount of Jitter injection is calibrated with the Bathtub measurement capability of J2 and J9.
