 |
|
Hi
Why is the Resolution Enhancement option greyed out in the Spectrum Analyzer probe options box?
I'd love to be able to use it.

Hi Tristan,
In Scope View, Resolution Enhance uses an FIR (finite impulse response) filter to smooth the data and reduce the effect of noise, such that, the signal is effectively low-pass-filtered.
In Spectrum View, you have great control over the spectra of interest by manipulating the Spectrum Options and frequency range.
Regards

Hi!
In another spectrum analysis program I use with a firewire soundcard a Kaiser7 window/filter is suggested and used for analysis of distortion. This seems to give better results than the options in Picoscope. Any plans on adding other filters/windows for Picoscope?
