I configured "CO Pulse Freq" to point to "Dev1/ctr0". Then I connected the oscilloscope's Channel #1 to BNC 2110 Trigger / Counter block counter #0 and I could see the pulse wave form. Furthermore, if I stopped the VI, modified the frequency and started it again, the waveform on the oscilloscope changed to the frequency I desired. Thanks for your help. | |

In the video they use Analog Output, but does it make sense for me to be using AO? Basically I just need pulse waveform controlled from labview but displayed on the o-scope. | |
