Can - I Use a NI6711 card for generate the following signal?

[Giorgig]

I need to generate four signal:

1) One sine- wave signal from 0 to -4 Volt, and frequency less than 100 KHz.

2) One trigger signal, amplitude 10 V, frequency 3200 Hz and pulse- width from 1 to 10 micro Seconds.

3) Two trigger signal, amplitude 5V, frequency 0.4 Hz and pulse- width 20/70 mS in opposite phase.

4) Two square wave signal amplitude 5V, frequency 2 KHz, in opposite phase.



For this application I have thinking an Ni6711, my idea is that:

One of four analog output for generate the first signal.
One other of three free analog output for generate the second signal.
Two of 8 digital I/O for generate the signal at te thidr point.
The counter/timers output for generate th
e two signala at the four point.

I want use for work only Visual Basic.

It Is possible?

Tanks.

Hello;

You definitely can use the Analog Output channels to generate the first two waveforms, and the two available counters to generate the last two channels. Regarding your third signal requirement, you would need to have two more counters to do that. I'm saying that because, the digital lines of that board don't have strobed operation capability, meaning that you will need to make function calls to update the digital lines at each time. As that will be Software timed, you will not have the necessary accuracy to generate a nice square wave.

The better way to do that would be to get another DAQ board that has 2 counters available, and synchronize both boards though the RTSI bus.
Hope this helps.
