Re: Issues with TinySA USB Connection in C#

Re: Issues with TinySA USB Connection in C#

Re: Mesure IMD with Two Tone and TinySA Ultra

Re: ultra+ trigger options
Thanks for the answer.
Was hoping to leave the sa some distance and be alarmed by a beep when it captured something.
Will try if the output can drive a small piezo speaker.
