Re: Frequency Response with Pico 4262

Hello Peter , hello Martyn , Thanks a lot for your answers. - I think it's better to work only from 1 to 20kHz because, as Peter said, the frequency response of the AWG is not very good above 40kHz (even above 30kHz...). - About activation of AWG after or before configurating it : (that's for Martyn...

Re: Frequency Response with Pico 4262

Hello, :D :D THANKS A LOT PETER : it works perfectly!!! :D :D Just few comments about the generator of the 4262 : - I think it would be better to setup before activation, and not after (especialy for amplitude). - the highest frequency with the sweeping mode (20kHz) is too low : 50kHz would be very ...

Re: Frequency Response with Pico 4262

Hello, thanks for the answer, but I would say : "so what???" Another test (done with other amplifier) : Settings are : 1° Generator : sin 20kHz up 200Hz 200Hz (increment) 60µs 2°) Scope : +/- 1V 200µs/div 500S 3°) Spectrum : 256 Flat top Peak hold 200kHz All those settings are similar as setting in ...

Frequency Response with Pico 4262

Hello, I want to mesure frequency response of amplifiers from 5Hz to 20kHz. Thus I saw the video about it in Youtube with the 4262. I also have a 4262. So I've tried with the following settings (quite the same as in the video) : 1°) Generator : - sin wave - start frequency : 5Hz - amplitude : 400mV ...

Saving view and measurement

Hello, I would like to save both measurements and view (as the result you can have when you print a view with measurements), is it possible? I can save the view but not with the attached measurements. Thanks. Regards. Glubbein PS : the 4262 is realy a very good device, a pleasure to work with :D

Low Pass Filter with Pico 4262

Hello,

Is there any filter (low pass) in the 4262?
I would like to use 30kHz 22kHz and a 80kHz PB filter for THD+N and SNR measurements with the spectrum mode.

Thanks.

Regards.

Re: Trouble FFT and distortion mesure on Pico 2203

Hello Ziko, thanks a lot (especially for the last picture)... Now everything is clear : my problem is the fact that the 2203 is an 8bits, and an entry level scope (as you say), and nothing else! A 4262 would be the solution, but since my use is not a professional one, the cost of the 4262 is a probl...

Re: Trouble FFT and distortion mesure on Pico 2203

Hell Ziko, 1°) repeat trigger instead of auto trigger : it doesn't change anything : signal : 1,7kHz, sinus, 3v p to p (from my Marconi generator) acquisition with repeat trigger, both channels at +-10V Spectrum : Hann, average,... both channels at +-10V Marconi 1,7kHz 3V Ch A B +-10V.jpg 2°) OK for...

Re: Trouble FFT and distortion mesure on Pico 2203

Hello, I found a video here in the topic named : "Picoscope 4262 distortion mesurement floor". So I dicided to do the same operation than in the video. 1°)Using exactely same settings (spectrum frequency range=5MHz) : - signal : AWG sinus 1kHz 900mV - acquisition : 100ms/div 32 100ks +/-1V - spectru...

Re: Trouble FFT and distortion mesure on Pico 2203

Hello Ziko, thanks a lot for your help. 1°) I've done a mistake : the amplitude setting in spectrum analyzer was wrong (too low ---> big distortion!!) :oops: 2°) But I still have many problems : a) mesurement of THD (in %) : signal : 1,7kHz sinus 3V peak to peak spectrum settings : 39,06kHz Hann Win...

Trouble FFT and distortion mesure on Pico 2203

Hello, I bought a PICO 2203 about one year ago, but starded to use it juste a few weeks ago. Everything works fine except distortion analysis To show you the problem I've done two tests : a) with a very low distortion sinus generator (Marconi TF 2005R), an HP8903 distortion analyseur (witch cane giv...
