THD Measurment 100th Harmonics

Post by Stibra »

Hello Picoscope,

We have recently bought the Picoscope 4244.

Is it possible to display up to 100th Harmonic in Picoscope 6? If not is it possible to create a math function that does?

Normally we have been using the Fluke 199c for these kind of measurements.

Hi this depends really on the kind of signal you are looking at. The software does not identify different harmonics however it should show them (depending obviously on what the signal is). For example with square waves you would easily see lots of harmonics.
You would have to search for the harmonic manually, which is achievable if you knew the fundamental and then use the cursors.

Kind regards
