Signal Acquisition with high sampling rate

[IntuitiveAnalog]

Hi everyone,
I have a PWM sort of wave having frequency of few kHz and 0-10 V amplitude, which I need to acquire (for post-processing with MATLAB) using acquisition board/kit with a high sampling rate of the order of a few GS/s.
I will be thankful if anyone could give an idea about acquisition board/kit which should be used for this purpose.

Thanks

It is a huge sampling rate, perhaps not too easy to find boards with such a specification, anyway had you seen the National Instruments portfolio ?

Are you sure you need that sampling rate? That's oversampling by several orders of magnitude.

Most scopes let you capture data.

Yeah I have seen some of the boards from National Instruments, but have not come across such high sampling rate yet.

Yes, that's the requirement.

Most scopes let you capture data.

What exactly do you mean by it?

It means that unless you are planing to process this data in realtime ( which should be done within the acquisition board ), you should capture a stream and store it for further processing. Once again, you're dealing with a huge specification; this is implemented on professional systems by multiple A/Ds working together, interleaved.
