Most designs feature input monitors. The basic functionality is an edge counter monitoring each input channel individually - if read out e.g. once per second one can easily display the rate of input pulses. Besides that there is a high-resolution mode available: One input channel can be selected and the counter be sampled with a given period, down to 100 ns per sample. A buffer stores up to 1000 samples that can be read out subsequently for detailed rate analysis, for example to check micro-structures of the spill or to see if hits close to each other deteriorate the detector performance.
Most TRB3 designs contain the feature to forward signals from any input to the CTS to be used for triggering. That is, any input to a TDC design or the data from ADC-AddOn crossing a configurable threshold can be selected to be forwarded to the CTS. The signal is sent on-board the TRB3 or using RJ-45 cables between boards. For convenient use, a coincidence between two groups of signals can be generated as well.
Using this features gives various options to trigger on input signals - without the need to install a dedicated signal cable to the CTS.
