keyword=HAPPEX DAQ: Added another 18-bit Voltage ADC to the Counting House
This one will be used to replace the 16-bit ADC currently being used to read
out bpm12 signals.
The 16-bit board has been saturating lately, so this should fix the problem.
The 18-bit board that was installed has a range of about 7.5 Volts, as opposed
to the 16-bit board which had a range of 5 Volts.
Run 12153 was used to test the range. During run 12154 I connected the bpm10
signals to the 18-bit board. This is to make sure the data makes sense and that
differences can be calculated properly.
