The binary bit stream arrives on one pin on a circuit board and a synchronous clock arrives on another pin. I don't need to store the clock - it's just there in case I need to use it during the capture.
The length of each burst can be anywhere from 1200 to 60,000 binary bits - depending on how much data I request each time. I want to capture the simple stream of binary 1's and 0's, then store it, probably broken up into 8-bit bytes and request another burst, so I have time to do the actual storing of the data on a medium, SD card, hard drive etc. because no more data will arrive until I ask for it. As I said, I have the option to request shorter bursts, as short as 1200 bits in a burst, but in all cases the arrival rate of the bit stream is 1.5 meg bits/second.
I've looked at the specs online of several digital storage oscilloscopes but they sample and store csv voltage values, which is useless. I simply want to store the 1's and 0's that arrive during the burst.
Does anyone know of a data capture device that do this? This is a one-shot data capture, where I'm rescuing/recovering data from a device, 5 meg bytes in total and once I have it captured the job is over.
I've looked at a few serial port-to-SD card devices from the Arduino world but they don't seem to fit the requirement. Perhaps there is one that does but I haven't discovered one yet that looks capable of doing this job.
Many thanks to all who take the time to read this and give me pointers.
