Hello
The attached VI modifies an input signal (train pulse). The signal is delayed (t1, t2, ti) and it will stay like that for an amount of time (T1,T2,....Ti). After processing such signal, the result will be an input signal for an electronic circuit.
The main problem is when the DAQ Assistent is set, and gets the processed signal, for putting it in an analog output
Thanks in advance

Well, you are giving it a waveform to output when you configured the task for 1 sample. Try changing to N samples or to Continuous Samples for the Analog Output.

When i try to choose in the daq assistant interface the option of continuous samples or N samples, the following error shows up (see attached image).

That is a problem. The USB-6008 only has static analog outputs. This means that you cannot output waveforms at the rate you are trying to accomplish. Maybe the USB-6003 can do what you want.

John,
Are you by any chance a Student? If so, invest in an NI MyDAQ, which has far more capability than the USB-6008, can output analog waveforms, and is amazingly inexpensive for students. A number of excellent Biomedical Engineering programs require that Freshmen purchase one (cost is comparable to a good textbook, maybe two), and they find that they use it all the time in their Instrumentation and similar Labs. Plus they can take their circuits home with them and do "home-work".
