Spectrum lab is excellent!
I can see there is a plugin to demodulate I/Q. I have not used it extensively but I hope you could connect directly the outputs of an image reject mixer to the stereo input of a PC soundcard to recover and filter the audio.
I would like to ask you if there is any plugin for the inverse process, i.e to create an audio I/Q signal (two audio signals filtered and with 0 and 90 degrees phase difference) in order to drive an I/Q mixer for SSB modulation?
If there is not, do you know of any program that could be able to be used for this?
I am making a microwave transceiver and software can minimize complexity if it can be used for modulation and demodulation processes.
