Bode chart with PicoScope 3205

One of its features is test the bandwith response of a filter using the sweep function with "peak hold " into signal genarator. I can´t get good results.
Could you advise how to do this?

Thak you

Many Thanks
Sarah

Hi,
Sorry , my english too poor!

I want to make a frequency response chart, this is a Graph of dB vs kHz of any sample like a filter.

Looking into picotech web page, it says:

"Built-in Signal Generator

The PicoScope 3204 can output a fixed 1 kHz square wave for compensating oscilloscope probes. The signal generators built into the PicoScope 3205 and 3206 can output sine, square and triangle waves up to 1 MHz in frequency. /////A useful feature is the sweep function that can be combined with the spectrum analyzer peak hold function to quickly test the bandwidth response of filters and amplifiers.////"

I hope this clarify my question.
Best regards,

Ariel.

Hi

Thank you for your post.

I donot have specific or detailed information on how to carry out this analysis. You may find our audio analysis pages useful:

http://www.picotech.com/applications/spectrum.html

These detail many experiments that can be carried out with the ADC-216 which relate to audio but some of them could possibly be done with the PS3000 and you might find what you are looking for there.

Best Regards
Sarah
