I've recently purchased an Owon VDS1022i usb oscilloscope and am both impressed and frequently bewildered by it. For the most part it seems to be quite good within its technical limits. The computer based user interface is more than a little baffling, since I'm still stuck in the Tektronix 500-series mindset 8-)
One feature that looks new and interesting is record mode, which writes data to the computer's storage and seemingly sidesteps the
1022i's very limited sample length. Potentially measurements could run for hours, or so I hope. There are two parameters that can be set in the record setup: interval time and frame numbers.
The manual describes how to capture a record, but not much more that I can make out. In particular, the relationship between interval, frame number and sampling rate isn't obvious. Neither is the data format used in the saved file.
For example, can anybody give a hint how I might record a battery voltage curve during charge and discharge over a period of a few hours?
So far I've been using the Linux UI developed by florentbr on GitHub. If it helps I do have a Windows 10 machine available to try.
Thanks for reading
