Why do I get horrible resolution using Benchtop Function Generator.vi

[Johnaxe]

At 200 Hz, the resolution on my Oscilloscope is horrible, I am running a sine wave, but it looks more like a square wave. What can I do to improve this so that I get good resolution at 1000 Hz

Hi John!

The infos you provide are very scanty.
Please tell me, what Hardware and Software you use. Are you measuring a real word signal or a simulated (Software)?
If you are measuring a real world signal - what device do use to accomplish this?
Please be aware of sampling theorem!

Hey Stefan,

I seemed to have fixed the problem by using Function Generator VI, and not the benchtop one. For some reason, now I have great resolution up to 1000 Hz, and that is the limit, when the system can no longer keep up. Thanks for you help. I am using labview 6.0.2, with a NI PCI-MIO-16XE-50 Multifunction DAQ card.
