  1. Hi I am new to the DD, and I thought this might be a good device to obtain readouts at high speed from my photon counter that outputs a 3.3v pulse every single time it receives a photon. The maximum speed it can go is at about 25ns per output. So I looked through some of the examples in the SDK (so I can automate the process, without having to save the data file each time and process it later). 1) It is not clear to me how I can extract the data from each channel using the SDK, or rather how I can specify which channel to log the data 2) I am wondering what is the maximum throughput, in the case I want to obtain data from multiple photon counters (e.g. 8 channels at 100MHz) 3) Also, if I implement a script to do a mathematical routine which will compress the amount of data (e.g. number of pulses over a period of time, or mean and std of pulses over a given time) is the script implemented on board or after it arrives in the cpu (post processed)? 4) Would I be able to get the time (or ticks) the pulse is received so that the data load is greatly reduced (since I do not necessarily need the 0s in the pulse stream). Thanks.
