Re: Frequency Response Analyzer with Bode Plots

Hi hexamer. Thanks for your reply. I mean. for example: - Input 1Vpp 1khz -> Vacuum tube amplifier -> 8Vpp output with perfect Sine Wave -> Capture - Input 1Vpp 15khz -> Vacuum tube amplifier -> 8Vpp output with Sine Wave was cut off the head (not perfect Sine wave output) -> Capture in the both ca...

Re: Frequency Response Analyzer with Bode Plots

Hi Hexamer. Have nice day and thank you very much for your reply. That's great to me. I would to buy 2204A one. My amplifier just around 10W with 8R spearker load. In some case, it would be 15W-30W so I'll notice the maximum of PS2204A inputting is +/-20V. I have one question that the process of ca...

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

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...
