    keyword=access work for pvdis

    In both spectrometers, a copy of each VME1 and GMN2 signals from Happex
    timing board is taken to pvdis setup to replace existing pvdis LNE and
    MPS signals, respectively. The fan out of these signals has no
    interference with Happex setup, since the fan out copy has perfectly a
    NIM signal (for both Happex and pvdis in left HRS and only for pvdis in
    right hrs (since in right hrs happex uses an ECL cable, no problem here)).

    From here, only for pvdis:

    In both hrs pvdis setups, replaced 100 kHz signals from left hrs 103.8
    kHz clock (this hrs 107.8 kHz clock is also taken to right hrs pvdis
    setup). Tried to do left pvdis troubleshooting, only two runs with pocket
    pulser as input taken (run 24932 with all ribbon cable polarity not
    changed, run 24933 only top TDC ribbon cable polarity flipped). Analysis
    will be done later.
