Hi Abishek,

It is true that there are PC cards that can digitise signals at high speed. The level of sophistication depends of course on the software that processes the output from the card. And since you have the full power of the PC available, this can be very sophisticated. Cards like this are made by companies like National Instruments and others.

However, the Velleman device Kai mentioned and the PICO scopes mentioned in an earlier post are well worth looking at. They may give you better performance at a lower price.
