Re: PicoScope 6.10.8: Log frequency axis

Hello! I would like to poin again the attention to a new feature for log sweep mode or decade sweep mode with number of points per decade or octave. The current linear mode is not correct for 20Hz to 20 kHz. I always se a bump to the lower part in spectrum view peak hold. I used the procedure from t...

Re: PicoScope 6.10.8: Log frequency axis

Hello! I tested the feature yesterday and it works nice. But I would like to mention one point. Using the internal wave form generator of 4262 it is not optimal to have a sweep increment which is linear and the frequency spectrum axis is log! It should not be so complicated to change the sweep incre...

Re: PicoScope Beta 6.10.2: Log frequency axis

Hello Jeff!

Thank you very much for implementing this "missing link" to many Audio spectrum analysis!

Works great so far.

BR!

Re: Frequency Response with Pico 4262

Hello

could you please also provide such a file that doubles the frequency only?
So, if you configure 5-20khz it would be 10-40khz. That would give a reasonable range for any amplifier testing.

And I would fully agree that the generater should be configurable before activating it.

Best regards!

Re: Frequency Response with Pico 4262

Hello,

I think the reason is that the sweep begins with a psoitive number like 20 Hz and the x-axis starts at 0 kHz. It:s the same as you see after 20kHz

Re: log-scale?

Hello,

what I forgot. The equivalent feature needed is a log sweep mode for the builtin func gen. Many users also requested this. I think these two features are the missing link for audio analysis.

Re: log-scale?

Hello Martyn, thanks for your answer! The 4262 is really a great scope for audio analysis with it's 16 Bit, bandwidth and builtin function generator. But please ask your head of dev if they have ever seen a linear scale of a published frequency response analysis of any amplifier? To be honest I expe...

Re: log-scale?

Hello,

is there any progress concerning this issue? I have an 4262 and for frequency analysis this is a must.

Thank you in advance!

Frequency response analysis with 4262

Hello, this scope has a function generator onboard and should have been designed for analogue signals. I would like to know if it is possible to do an automatic frequency response analysis of an HiFi amplifier running a sweep from 20Hz to 20kHz and let the result show in one window as a standing gra...
