Harmonic analysis with version 6.2.2

Postby maxsca » Mon Mar 30, 2009 9:27 am

I have a problem with the 3224 model PicoScope 6.2.2:
performing the harmonic analysis of a signal at 23 Vpp at 1 KHz, i found that the measure changes according the probe attenuation:

probe 1:1
amplitude measure : 23 Vpp
distorsion measure : 0.7% THD

probe 10:1
amplitude measure : 23 Vpp
distorsion measure : 1.7% THD

With an old version, 6.0.xx example, the two measures are equal.

Best regards.

Hi

I think this might be a bug in the software. We will look in to it.

Thanks for bringing it to our attention.
