Thanks, Tom. Just to clarify, the 1Msps comes from the sample rate of 50M and the decimation of 50, correct? Also, is this going to record 10 seconds of "real-time" data? I was having issues with real-time, due to the large data stream, so will this record data from t=0 to t=10, just not in real-time?
