I've just dug out an old ADC-200 (from about 1998) which I am trying to use with an equally old Toshiba laptop, running DOS (both the software which came with it and the latest from the web).
The problem is, it seems to refuse to store more than 256 samples per channel, even though the spec says there is an 8K sample buffer per channel. For instance, if I set the timebase to 500 mictoseconds/div (5ms/screen), the sampleing rate is 48.4k samples/sec, whereas I reckon it should be sampling at 1.6M samples/sec to fill the 8k buffer.
I expect I've missed something obvious, but I can't find what it is. Can anyone help, please?
