The RX channel tab employs green shading to highlight the enabled
RX features

(RX polarity inversion, RC, LDEQ, MPICAN).

Rx Diagnostics

To access the RX diagnostics graph section, select the RX
button found in the RX configuration window of each
channel.

After pressing the button, RX diagnostics button is shaded
in green and

a graph section will appear as shown in Figure

27.

The Rx diagnostics features 3 measurement tabs:

▪

FFE Taps:

Displays the Feed Forward Equalizer tap

values.

▪

SNR:

Measures Signal to Noise Ratio in decibels

(dB).

▪

Histogram:

Measures density distribution of the

samples.

Screenshots of the available RX diagnostics measurements graphs are shown in Figures 29-31.
