July 28th, 2018 Testers: Cameron, Ye Tian, and Bob

See Today's Meeting Notes

Goals

  • Test QWeak ADCs in Counting House Parity DAQ to verify that the Control.db updates by Bob are working and PAN (~apar/bpan18/pan)

Testing channel mapping and PAN ADC arithmetic

For notes on 12 and 16 bit DAC calibration see July 28th DAQ Testing Notes.

To use the DACs:

  • Log into the Counting House ROC with telnet over acons1 console server (see Network Map)
  • Set the DAC output level with the C code command setDACHAPTB(DAC#,Level#)
  • Read the DAC output level with a voltmeter (as a check of functionality)
    • DAC# 1 = 12bit, 2 = 16 bit
    • 12 Bit DAC Level#, positive voltages for values that range within Level ⊂ [0, 2^12 - 1 = 4095] modularly
    • 16 Bit DAC Level#, negative to positive voltages for values that range within Level ⊂ [0, 2^16 - 1 = 65535] modularly
  • Test channel vqwk3_5 == bcmcav2r (Cameron suspects this QWeak ADC has substantial non-linearities)
    • CODA Run 4533
      • Events 0-700 -> DAC(2,0)
      • Events 700-2000 -> DAC(2,10000)
      • Events 2000-3500 -> DAC(2,20000)
      • Events 3500-5000 -> DAC(2,40000)
      • Events 5000-9000 -> DAC(2,60000)
    • Running bpan18 and "R->Draw("bcmcav2r:ev_num")" or "R->Draw("vqwk3_5:ev_num")" both show the same results (and appear to have a linear ADC response - ramp DAC function should be used)
    • Coda run 4534
      • Events 0-1000 -> Whatever hardware signal was plugged in
      • Events 1000-5000 -> DAC(2,ramping)
  • Test all Cavity BPM channels
    • CODA Run 4535 - Ramp_CH configuration running 16 bit DAC ramp function (~1000 events per cycle, 2 cycles per channel)
      • Events 0-2000 -> Channel BPM B X -> vqwk3_0 - raw good, and bpmcav1xr - control.db error, fixed
      • Events 2000-4000 -> Channel BPM B Y -> vqwk3_1 - raw good, and bpmcav1yr - control.db error, fixed
      • Events 4000-6000 -> Channel BPM B Q -> vqwk3_2 - raw good, and bpmcav1r - control.db error, fixed
      • Events 6000-8000 -> Channel ??????? -> vqwk3_3 - raw good, and was wrongly mapped to bpmcav2xr, fixed
      • Events 8000-10000 -> Channel BPM C X -> vqwk3_4 - raw good, and bcmcav2xr - control.db error, fixed
      • Events 10000-12000 -> Channel BPM C Y -> vqwk3_5 - raw good, and bpmcav2yr - control.db error, fixed
      • Events 12000-14000 -> Channel BPM C Q -> vqwk3_6 - raw good, and bcmcav2r - control.db error, fixed
      • Events 14000-16000 -> Channel ??????? -> vqwk3_7 - raw good
    • CODA Run 4536 - Ramp_CH configuration running 16 bit DAC ramp function (~1000 events per cycle, 2 cycles per channel)
      • Events 0-2000 -> Channel BPM B X -> vqwk3_0 - raw good, and bpmcav1xr -
      • Events 2000-4000 -> Channel BPM B Y -> vqwk3_1 - raw good, and bpmcav1yr - good
      • Events 4000-6000 -> Channel BPM B Q -> vqwk3_2 - raw good, and bcmcav1r - good
      • Events 6000-8000 -> Channel ??????? -> vqwk3_3 - raw good,
      • Events 8000-10000 -> Channel BPM C X -> vqwk3_4 - raw good, and bpmcav2xr - good
      • Events 10000-12000 -> Channel BPM C Y -> vqwk3_5 - raw good, and bpmcav2yr - good
      • Events 12000-14000 -> Channel BPM C Q -> vqwk3_6 - raw good, and bcmcav2r - good
      • Events 14000-16000 -> Channel ??????? -> vqwk3_7 - raw good
    • CODA Run 4537 - Ramp_CH configuration running 16 bit DAC ramp function (~1000 events per cycle, 2 cycles per channel)
      • Events 0-2800 -> Channel BPM D X -> vqwk4_0 - worked, good raw and named
      • Events 2800-4500 -> Channel BPM D Y -> vqwk4_1 - worked, good raw and named
      • Events 4500-6500 -> Channel BPM D Q -> vqwk4_2 - worked, good raw and named
      • See plots of raw and named vs. event number, and correlation between the two.
    • CODA Run 4538
