Sampling of sporadic fast signals over a long data acquisition session, SDK

Post by bwu88 »

Hi,

I have an application and a spare PicoScope 6462E available for use, and I'm trying to understand if it can do what I'm looking for.

Signals of interest (analogue) are randomly distributed but occur at approximately 1Hz over a measurement period of a week.

The signals are quite fast, have a width of approximately 10ns, and may be coincident across channels. For each trigger event I'd like to retain only the samples acquired for trigger_time +/- 20ns and write them in real-time to a log file for each channel. All without missing any signals while the PicoScope is transferring acquisitions to the host.

At first glance rapid block mode looks the most plausible sampling mode, but the potential for missing signals still seems to remain.

In principle, is this combination of fast sampling and a long data acquisition period plausible using the SDK?

Any perspectives would be appreciated.
