Re: Frequency Response Analyzer with Bode Plots

Hello hexamer. I am very interested in this project and I have read it from pages 1-30, thank you for your research and development. Personally, I often make (diy) some vacuum tube amplifier to listen to music with the frequency of 20hz-20khz for 2 speakers Left and Right. Let me ask is with PS2204...

Re: Frequency Response Analyzer with Bode Plots

Hi Aaron, I have a "newbie question" regarding compatibility with Windows 10 64 bit. As there have been discussions about issues related to 64 bit systems: Does your software work on my Win 10 pro 64 bit, or do I have to build the system based on an older windows PC with a 32 bit OS? Kind regards, ...

Re: Frequency Response Analyzer with Bode Plots

Hi Aaron, I'm trying to work with your app using a 64bit python process, so far proving tricky. Any hints on that? Or maybe a planned release of a 64bit dll? Thanks, Jeremi I suspect that's the issue (similar reason why 64bit Excel won't work, see a few posts earlier). I certainly hope to release a...

Re: Frequency Response Analyzer with Bode Plots

Hello! I am trying to use PicoScope5443D with the latest version FRA4PicoScope 0.6.2b.msi. I have two problems though. 1) There is a fatal error saying "ps5000aSetChannel( 16384, 2, 0, 0, 0, 0 );Fatal error: Failed to disable channel: 290 Status: 5443D S/N: GX150/0121 successfully initialized." 2) ...

Re: Frequency Response Analyzer with Bode Plots

Hi All, Sorry for what may be a very low level question, I'm new to oscilloscopes and am considering buying a 2000 or 2200 series Pico in order to do Bode Plots on guitar pickups, as I build my own for my line of guitars. I understand that the plot capability isn't available stock on the device, bu...

Re: Frequency Response Analyzer with Bode Plots

Hello Aaron, again me with a question for improvement. I am testing my 0.1 .. 10 Hz Low Noise amplifiers with a PS5444A. When I try this frequency range with 24 steps/decade I get several duplicate frequencies. Obviously the minimum resolution of the PS5444A is 0.04 Hz from frequency step to freque...

Re: Frequency Response Analyzer with Bode Plots

Hello, I have a PICOSCOPE 5444B and 2207B, FRA works like a charm on the 2207B but limited to 1Mhz. Can this limit be lifted ? what are the limiting factors ? I am sorry for my ignorance, i am new here . I tried with FRA with my PICO 5444B but i get error : Error: Unable to initialize device with s...

Re: Frequency Response Analyzer with Bode Plots

Hi Aaron, Thank you for the wonderful job you did with FRA4PS. The more I use it, the more I like it, however concerning noise suppression I have a few questions. With my 5243B I already use the "noise reject" option which was already a big step forward. 1) I can also choose a "noise reject bandwid...

Re: Frequency Response Analyzer with Bode Plots

Hello Aaron, It has been a while. I am back in the power supply mode. When we last spoke I was working with version 0.6.1b. I just installed your version 0.6.2b RC4. Could you tell me some of the changes in this latest version. I have a 2208B USB Pico Scope. Thanks / Charles Hi Charles, It's mostly...

Re: Frequency Response Analyzer with Bode Plots

Hi Aaron, I just had an idea for a workaround against the AWG discontinuities: when you can manage to make the AWG oscillate for an exact multiple of full periods of the test frequency, the switch-off transient will be just the negative of the underlying switch-on transient. So all you would have t...

Re: Frequency Response Analyzer with Bode Plots

Thank you to Martyn for adding the attachments I was referring to in the prior post. The first is with 1 Hz bandwidth and the second with 0.1 Hz.

Re: Frequency Response Analyzer with Bode Plots

Result were indeed much better at the high frequencies, but now irregularities show up in the low frequencies. Hope this is logic for you Yes, this makes sense. When we set a fixed bandwidth, the application will try its best (within limitations of the scope's buffer size) to maintain that bandwidt...
