Spectrum mode: DC offset measurement

Post by frank71 » Mon Sep 24, 2018 8:32 am

Sinusoidal signal, 1Vpk with 1V DC offset.
In spectrum mode I measure a DC offset of 2V not 1V as expected.
1kHz component is correctly estimated about 0,7V (RMS value of 1V)
Where I am mistaking?

Hi Frank,

I've just being going through forum posts and noticed that you never got a response for this issue. If this is still an issue for you could you send it in to us at support@picotech.com with a full description of the problem with an example data psdata file.

Regards,
