Signal Recovery 7230 lock in - Circular fast curve buffer?

[ibutters]

I'm trying to implement a circular acquisition using the 200kHz ADC rear inputs on the Signal Recovery 7230.

I can succesfully capture 100,000 points at 200kHz, which is the buffer limit, but I can't work out how to implement a circular implementation, i.e. with data overwriting the oldest data, to allow capture of events up to the time of an applied trigger, and pulling the data off in paralell.

The manual states it can be done, but I can't find an implementation.

Does anyone have any experience of this?

Thanks,

Ian

Hi Ian,

The Signal Recovery 7230 is not one of NI products, thus it would be very difficult to assist you. Maybe you will have more luck by posting on the vendor's forum.

Apologies Shalini, my question was slightly more LabVIEW specific than it appeared!

I was hoping that someone on here had achieved this with labview.

However, it appears, after some more research, that it isn't possible. At least at 200 kHz.
