Hello,
i´m starting with labview and NI USB-6009 at work.
I have to generate from a txt file (with 0 and 1) a digital signal with variable frequency typ. 1.2Mhz.. The level of the 1 (the amplitud: Vcc) should be variable too (1v<Vcc<7v).
The first question is: it is possible to choose differents amplituds for a digital output in the NI USB-6009?
The second and more important is: why my VI is not working?
I can see the digital signal in the grafic in labview and it is correct.
The problem is when I try to see this signal from the output usb-6009 in the oscylloscope. I see only pulse 1010101010..., and not the secuence from my txt file and the frequency don´t correspond to the signal I have genereted.
I have attached a typical txt file, that I am using and the VI file.
I hope you can help me and sorry for my bad english...
Thank you!
