Testing out the new IQ Demux and Constellation filter blocks in ngscopeclient.
IQ Demux is intended for working with 2D modulations where you have the I and Q values sent consecutively on the same channel. It splits out the interleaved I/Q values to separate channels which you can then feed to the constellation filter.
Of course, the 26 Gbaud PAM4 PRBS I'm looking at here isn't actually a vector modulation, but it's a convenient source of fairly clean test data.

@azonenberg That's a lot of baud. I remember 45.45 baud and still use it occasionally. Then came 110 baud over telephone lines. Whoo hoo! 300 baud was thrillingly fast.
Hahaha. (Yes, I'm old.)
