How to regularly manufacture pedestal events in the data stream

Statement of desired functionality

A pedestal event is typically defined as one that captures data uncorrelated to detector activity but has timestamp information. This can be used to determine if the DC baseline is drifting over time such as from 60Hz noise, leakage currents, etc. To capture such information there has to be a way to make the digitizer's discriminator "fire" even though there's no edge to fire on, and a way to make this happen simultaneously across all digitizers but at a rate that is uncorrelated to the timestamp or beam frequency.
