Is there a method to decrease a DSO sampling rate intentionally so that longer capture window times can be achieved [at one-shot capture mode] ?
For example, given a 1Mb/s max digital data input, and a 1G Sa/s scope with a 100Mpts memory depth.
A one shot capture at full memory depth will span a 100ms time window.
Is there a way to intentionally decrease the sampling rate to, say, 10M Sa/s (which is enough for sampling a 1 Mb/s data), and with the same memory depth get a span x100 (1G Sa/s / 10M Sa/s) folds more - e.g. 10 Seconds ?
