I need an equipment with an entry USB port to send a wav file and exit I & Q

[carlos__12]

We are working with an equipment consisted in a transmitter and a receiver.At the end we have 2 computers,we are trying to send a wav file through USB port from one computer and converted to I & Q signal (that supports our transmitter).
On the other end we have to convert from I & Q signals to a signal who can interprete the USB port.
Our ask is if exists an equipment which could do these two fuctions.
Thanks a lot.

We have data acquisition (DAQ) devices that have a USB interface. You could send a .wav file to an analog output of a USB-DAQ device and you could acquire an analog signal (with analog inputs on a USB-DAQ device) and write that to a .wav file with another USB-DAQ device.

What is an I&Q signal? You need to give more information on what what characteristics are needed for a signal to be I&Q. I have included a link below to a USB-DAQ device within our on-line catalog for you to take a look at.
