  1. Well you have larger wobbly bits than I, must be size of planets.
    Which brand and model of front end and cal relay? Aha, Omron. A picture is worth!
    Any idea of which FPGA’s, the JTAG connector might give it away, but there again pehaps not, I usually make flex adaptors for most projects nowadays. The SPI flash might be a clue.

    Be interesting to see what might be lurking on the I2C and SPI buses.
    The interesting thing is the lack or perhaps differing solder resist on the diff traces.
    Channel to channel isolation, or lack of hence harmonics, may well be due to “safety standards “. Have only seen Agilent with decent channel isolation. There again there is also the possibility of DSP compromise.
