My TPS2024 with the Power Application module installed the Harmonics selection does not properly measure the harmonics on my waveform.

My TPS2024 with the Power Application module installed the Harmonics selection does not properly measure the harmonics on my waveform.

The following shows an example of a waveform with harmonics.

If the secondary frequency is not an exact multiple of the fundamental the scope may display mixed results. The recommendation is to change the Setup selection in the Harmonics menu from Automatic to Manual. Reducing the vertical amplitude and/or changing the Trigger Coupling to Noise Reject will effectively increase the amount of hysteresis which can help improve the noise margin. Better results may also be obtained by reducing the number of cycles displayed on the screen.
