Agenda
- Bob : Teach Cameron and Chandan how to test QWeak ADC channels and look at data read into CODA
Minutes
Morning - 11AM - Bob, Cameron, Chandan
- Metrics for testing a QWeak ADC - it's easier since their dynamic range is much greater and the bit resolution is much higher for them (32 instead of 18 bit gives much higher resolution when digitizing)
- It works
- Does't saturate at -5 or +5V
- The zero volt signal is near the middle value of the dynamic range
- Look at pedestal noise (differences between neighboring events, or just ADC values with no signal)
- Use a modified rampdac16 command to put flat points at interesting voltage values for testing dynamic range
