An interesting find with the new sum inverter is that with the pulser at default settings the pulser peak on the n+n side is above the range of the ADC. We have checked signals from the sum inverter and pulser and both are equal in magnitude. We therefor determine it is over range as the charge is spread over 4 FEEs vs 12 on the p+n side. This possibly wasn't an issue with the previous inverter if it produced a lower amplitude. For tests going forward p+n voltage will be 2V. n+n voltage will be 0.5V - Attachment 1 Going to look into a 20dB attenuator Seems there were issues with the lemo cables in the n+n pulser chain
