Scale problem-Using labview to control a tektronix MDO3000 series oscilloscope

I have connected the oscilloscope to the computer,and  downloaded the oscilloscope's driver to control it.My problem is I want to show 100 cycles of signals on the screen,but when I run the VI,it automaticly show only two cycles on the screen.What should I do?

You should ask more data. 

That can be done in several ways, post your vi and the link to the driver so we can advise you more efficiently.

What is the frequency of the signal you are trying to capture?  You have to use that to determine how many data to capture.  The time you have to capture is T = (# cycles)/(Frequency of signal).  So if you want 10 cycles of a 10Hz signal, you have to get 1 second worth of data.
