A'n' = ( 2 / ( π × n )) × V Where 'V' is the peak-peak voltage of the squarewave and 'n' is the harmonic number (odd only). So if the squarewave is 2V peak-peak as shown, the 1st harmonic (the fundamental) is at 1.273V, the 3rd harmonic will measure 424.4mV, the 5th is …

Square wave created by an APx525 analyzer with the AG52 option, frequency domain. This is the best square wave produced by any audio analyzer in the world. The even harmonics are now 110 dB to 120 dB below the fundamental. At 1 MHz, the even harmonics are still 50 dB below the desirable odd harmonics.
