Phased array beam steering

[DelPiero]

Hello, not having much knowledge on LabVIEW I allow myself to solicit the forum for my code. I have to feed 16 speakers with the same signal but I have to be able to put a delay between each speaker in order to simulate a system like the one on the attached picture :

I hope that will be able to help me. 

Thanks to those who will consider this message.

Is this an actual system or a 100% simulation?

Because if it's an actual system, then you have hardware to hook up to a PC, and we would need to know what hardware that is to even begin advising on LabVIEW options.

At a general level though, this doesn't even sound like much of a "LabVIEW problem" because the sort of system that could do that with enough accuracy to actually work properly at the speed of sound couldn't run only in software, it would need to be hardware-based with some sort of software control.

This sounds like a very cool project.  Please stick to your original topic so we can keep the discussion in one place.  Thanks!

Thank you for your response.

Indeed, it is a real system. I am using a "NI PXI-1042" with which the speakers will interact.

You are right about the code, it seems relatively simple to do for someone (it would be mostly about understanding the software control) but with my lack of LabVIEW knowledge this is my major problem.

For the moment I tried to forget the real part of the system and tried to concentrate on the code only. I tried to generate a Waveform signal from which I would phase the other 15 signals. This did not give me any convincing result.

Oh sorry, I just sticked it.

FYI - PXI 1042 is just the chassis that holds the instruments.

Please excuse my lack of precision and thank you for your answer.

I will use 8 "XH-M543" (Digital Amplifier for Audio Amplifier Board (2-channel, 120 W, TPA3116D2, PCB PA3116D2)) to which I will connect 2 speakers each. These 8 boards will be connected to the terminal block "SCB-68A". Finally, the terminal block will be connected to the computer "NI PXI-1042".

Again, here you miss the instrument that connects to the SCB-68A, it does not connect to PXI-1042 but instead, an instrument plugged into PXI-1042, what is that instrument?

[DelPiero]

Oh sorry. Do you want to know the voltage generator ? My voltage generator will be the FAC-303 B. Here is the complete system.

Also to be more precise the SCB-68A is connected to the NI PXI-6723 part of my computer.

Thank you for your time.
