    keyword=IA feedback system not working


    I attempted to perform feedback. I had to fake the IA slope, which currently is too
    small (80 ppm/volt) to zero our large asymmetry (-1500 ppm). I plugged in a slope
    of 800 ppm/volt, just to test the system.

    The system failed this test. A charge asymmetry was measured and sent to the
    parity lock server, all three switches for this system were "enabled", but the
    timestamp was never updated and the DAC setpoint never changed.
