Ben Smith | Routine | Software | New script to equalize baselines | I've written a new script that will set all the V1725 baselines to the same level, by adjusting the DAC values. All the baselines are currently set to 15500.
The script is documented in the "Adjusting V1725 baselines" section of https://bitbucket.org/ttriumfdaq/dsproto_daq/wiki/Midas%20Software%20Operation.
I also added a new option to the "adjust self trigger threshold" script that allows the user to specify an exact ADC threshold (rather than doing it in relation to baseline). E.g. if you know that the baselines are all currently 15500, and you want to set a threshold ~200mV below, you could set a self-trigger threshold of 13900 (1mV is ~ 8ADC). |
