Error in scope&spectrum mode when measuring max level?

Post by Guest » Wed Dec 17, 2008 4:57 pm

Hello,
when I use the internal generator of my 5203, set to sinus/250 mV/1 kHz and read this with channel A in scope mode, I get a 'peak-to-peak' value of 515 mV. That´s ok.

In spectrum mode, almost independent of the FFT bins and window settings, I get an 'amplitude at peak'-value of just 180 mV. The spectrum range is set to 2 kHz.

Where´s the mistake?
Thanks in advance for your help,
Stanislav
