    Congratulations your videos are very interesting and instructive for someone like me who is approaching the rf world.
    Excellent explanation on imd3 that I understood here.
    Could you kindly give me some more precise information on how the sdg2032x generator (which I also have) should be set to generate the signals for the imd3 test? thanks for the videos
    thanks

      Hi Gregory! I follow and love your channel! Your videos about push-pull amps are very useful (the amp in this video is such an amp)! :)

    just noticed the amperage of the power supply keep oscillating 2A - 2.5A, since 2A was the max of the power supply, should one try the experiment again with a power supply with more amps?

      Ciao Lorenzo, no I said the max is 2A but in reality it should be capable of 3A: that power supply downconverts to 12V a source of 14V-3A, so even if there are inefficiencies, it should be able to convert 14Vx3A = 42W in input to 12x2.5 = 30W in the output. It's just that I don't trust it too much. I took the opportunity to order a better linear power supply capable of 5A eheh!
