I'm currently recording data points from an analog accelerometer(PCB 353b33) using a TDS3014B oscilloscope which has a Record Length of 10,000 points at a Sample Rate of 1.25 GSa/s. Since the oscilloscope is a triggered data logging device, it's not capturing the whole cycle of the experiment. I trying to look into analog data loggers that would help in seamless data logging for a minute or more with a good sampling rate that would help me capture data for at least one cycle. Is analog data logger the only option remaining? I'm not sure if an analog data logger would be a good solution for my problem, so if anything else would work for my case please suggest that as well.
There are many devices that would provide the recordings that you need. National Instruments makes a large number of DAQ devices that can record analog signals with very high fidelity. You could also use products from DATAQ. I would recommend something very cheap like the Adafruit Feather M0 Adalogger for projects that don't require the high precision of NI-DAQ or DATAQ instruments.
