Spectrum scale seems to show 2x f

Post by grendell » Sun May 20, 2012 1:44 pm

I have just started using the 2206 and upgraded to the latest software.

I was using the spectrum mode to check a phone line dial tone. The two frequencies detected were twice what I expected.

As a test I set the generator to 1KHz and the sweep to 5Khz and fed it to CHA. Again the scale showed a 2KHz main peak (and slight peak at 4KHz).

Changing to scope mode showed the frequency was indeed 1KHz as expected.

What am I doing wrong ?
