The MI-PE5620-8 is a PAM-4  BERT for QSFP-DD transceiver test. The excellent PAM-4 output signals and the full range of test pattern are ideal for transceiver compliance tests like the transmitter TDECQ test. The BER is measured in real time in all 3 PAM-eyes simultanously. The two boxes operate in the same clock domain.
