harmonic detector control not adustable on picoscope 6

Postby jackson » Wed Nov 10, 2010 12:06 pm

Have just installed software update 6.5.42.0 to picoscope 6

have found that in spectrom mode - measurement - (THD %, THD db and thd+n) - advance - harmonic detector
that the controls are fixed to the following and can no longer be adjusted

Highet harmonic - 2
Search bins - 1 [bin]
Harmonic noise floor 0 [db]

So only the second harmonic is detected.

hello, have been using the harmonic detector to measure THD on a 50HZ main power sine wave. The adjustment of the highest harmonic is working, but i found that the harmonic noise floor does not work. No matter what i change it to it always calculates THD using all harmonics up to the highest.
I manually calculated THD including all harmonics to the highest, and again using only the harmonics above 0dBv (where the noise floor is set at), and the results confirm my previous statement...
