Hallo,
@Hagrid:
"I would really appreciate it if somebody could explain this to me, thanks"
You are right, the noise of the 5000 serie is not that good.
https://www.picotech.com/support/topic16031.htmlBut in some cases you can lower the noise.
https://www.eevblog.com/forum/testgear/looking-for-a-dynamic-signal-analyzer-with-extended-bandwidth/?allYou can limit the bandwith and lower the noise. To limit the bandwith with the 5000 series you have different ways.
From PicoScope 6 help:
"Resolution enhancement is a technique for increasing the effective vertical resolution of the scope at the expense of high-frequency detail. In some scope operating modes, PicoScope may reduce the number of samples available to maintain display performance.
For this technique to work, the signal must contain a very small amount of Gaussian noise, but for many practical applications this is generally supplied by the scope itself and the noise inherent in normal signals.
The resolution enhancement feature uses a flat moving-average filter. This acts as a lowpass filter with good step response characteristics and a very slow roll-off from the pass-band to the stop-band."
You can limit the bandwith to 20 MHz
With math you can average to lower the noise.
