Previous Day of Testing << >> Next Day of Testing

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/pan/bpan18)

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
