Hai,
Is there is option to fold waveform , in INFINIIVISION 2000x series oscilloscope , if not plz tell me , which type of instrument can have?

No one else has this question

I'm not sure, but it sounds like you want to turn a waveform into an eye, much like my Forum picture. The 2000X scope can't do that, since it requires quite a bit of processing after the data is captured. You will need to go to one of the Infiniium series of scopes, like the DSO9104, for that capability.

In a word, no.

The InfiniiVision-X scopes use a proprietary sampling rate dithering algorithm to prevent aliasing (it turns the signal into wideband noise, as opposed to a sine wave at some wrong frequency). You cannot directly turn it off except on the 4000X series. however, since FFTs require equally spaced samples, turning on FFT turns of the sampling rate dither. So turning on FFT allows you to alias the signal, but you do not have direct control over the sampling rate. Changing the time scale changes the sampling rate, so, if you happen to hit a sampling rate you like, then you are ok, otherwise, no.
