The N variants feature NIM inputs and only appear to have + 16 channels. In fact they are 32 channel modules with every other channel + cabled from the front end to the ADC main board. This can be confusing. + The best way to think about the N modules is to ignore figure 4.6 in the + manual and to treat it like a 32 channel module for which you are only + using channels 0, 2, 4, 6...30. In that way you will understand how to set + the channel enables, and thresholds correctly, and unpack the data from the + module in a uniform way. + When reading the software documentation, please keep in mind that these modules are built on a common core module, a 32 channel peak sensing ADC with different front end boards that modify the digitization functionality.
