I need a device that will spectrum analyze the output of audio amplifiers to tell me the relative levels of 2nd, 3rd, 4th, 5th and 6th harmonics. Sine wave in, then a spectrum of the distortion harmonics at output as compared to the input. In other words not just a simple statement of the total THD amount. But maybe a simple bar chart report where the X axis shows the level of each harmonic where each bar represents 2nd, 3rd, 4th, 5th, etc... and the Y axis is the level. So, I can see the harmonic profile of an amplifier by each individual whole number harmonic. So, if for example my goal was to make an amplifier that has a greater level of 2nd harmonic than the 3rd harmonic. I'd be able to see if I'm on track to that goal as I change the operating bias of the tubes or other things in the circuit.
Can the Analog Discover 2 give me a bar chart, or the individual levels of each harmonic broken out relative to each other?
