When doing spectrum analyze on a sine wave I get different level depending on the setting on the bandwith. Very strange. I'm talking about 5-10% or so.
Is this a known problem?
I'm running the latest (I think) Picoscope6.
Thanks in advance!

Hi,
There will be some variation when the bandwidth is changed. The most accurate readings will be when the measured frequency is just below the upper range of measurement (a full scale reading). At higher bandwidth settings, when the peak is only a fraction of the full bandwidth, accuracy will suffer. The number of frequency bins selected will also have an effect.
