    Entry number 96280

    keyword=PZT scan complete


    Performed a parasitic PZT scan, starting with HRS runs 1968/20968.

    IHWP=OUT, RWP=6200, PC-POS=7.673, PC-Neg=7.569. 15 uA, 5 GeV

    Scan started right after run 1970, so that can also serve as a
    baseline.

    --------------------------------------
    1970 5 5 4.51
    changed ADC8 back to low gain, DAC Noise OFF.
    1971 5299 5 5 4.51
    moved feedback timescale to 1 minute
    moved ADC0->Low Gain
    1972 5300 5 9 4.95 5.64
    1973 5301 5 1 3.47 3.85
    1974 5302 9 5 6.91 6.75
    1975 5303 1 5 2.22 2.90
    1976 5304 5 5 4.5 4.49


    I left ADC8 in Low gain, DAC noise OFF, although it doesn't appear
    to be functioning well; the bpm wires it reads out track well
    with the BCM, but measure an unbelievably narrow position difference.
    I modified the template.db to reflect this change.

    The injector template was not modified to return to Random, Quad,
    Delay=8. (whoops... my bad) So I modified that. The .db files for
    recent injector runs (including those listed above) still need to
    be modified.

    ADC0 in the injector DAQ has been in high gain, and most channels
    are saturated. I didn't realize this until after the test, so we
    lost bpmin3, uh... whichever one that is. Anyway, I moved it to
    low gain after run 1976.

    I also returned the feedback configuration to a timescale of
    2 minutes. It seems that 1 minute works fine, but why mess
    with a good thing...
