Adaptive equalizer and channel IL estimator up to 14 dB (FFE+DFE). User-selectable CTLE 0-9 dB.
SNR monitoring over time.
Eye monitor.
PAM slicer threshold adjustable.

The ML4039D is a fully featured 200G BERT that can be configured as 4 channels of 28 GBaud PAM4 or 4 channels of 28 Gbps NRZ.
The receivers support FEC emulator (KS4, KR4 and KP4) on both PAM4 and NRZ eye modes and will return the post-FEC BER per channel as well as MSB and LSB BERs within the stream.

The receivers also show the eye’s Histogram and the channel’s SNR over time.

The transmitters support all standard test patterns mandated by IEEE and OIF such as PRBS13Q, SSPRQ and PRBS31Q. The user may also program the TX to output a user-defined pattern up to 32 kb long. The transmit power is adequate for testing up to 10 km SMF links.
