Hi all.
I'm looking to verify that I am using my new Picoscope 4262 properly.
I have a SMSL D-6 DAC which Audio Science Review has measured. I'm not expecting the Pico have anywhere near the resolution as the APx555 (obviously):

But why is this THD+N and SNR so low in 'Spectrum' view but when I just switch to 'Scope view', the same measurement looks a bit more as expected ?
Spectrum view, THD+N and SNR at 54dBc (strangely low) - see attachment
Just switching to scope view, THD+N = 84dBc - see other attachment
As mentioned I don't expect to see SINAD of 113 dB like APx555 analyser found but there is huge difference between 54dBc and 84dBc
I'm obviously doing something wrong somewhere
