Possible improvements Picosoft 6 & 7

Hi All, Years ago I sent many of these improvements to Pico, but none have been implemented so far in Picosoft 6 or 7. So I thought to post them here also, so maybe other users can confirm the usefulness: Spectrum mode: - Add scaling option in "units"/root(Hz) for each of the current units. This all...

Re: Frequency Response Analyzer with Bode Plots

(copied from my post at EEVBlog) I have been a big fan of using the app FRA4Picoscope to generate bode plots. This for me makes the Pico products much more useful. By using a reference resistor in series with a DUT, it is possible to calculate the impedance from the DUT. For this a made a small too...

Re: Frequency Response Analyzer with Bode Plots

In this model, since the calls to C# would still be static mehods, if you wanted to handle multiple instruments and enumeration, you'd probably have to use a handle as a parameter to these functions (like the Pico SDK). I was briefly thinking about creating a standardized version of the middle DLL ...

Re: Frequency Response Analyzer with Bode Plots

Hello! I have 3046D MSO and 4262 and Rigol DG1062Z and Siglent 6052X. I do know C++ and C# but my programmer-fu is very weak(not really actively programming in many years) , but would be willing to test and maybe fix minor things.. If I may make a suggestion: SCPI is just string exchange protocol, ...

Re: Frequency Response Analyzer with Bode Plots

I have downloaded all files to a local source tree folder, currently having a first look how to implement a dll in C# that can be called by your C++ interface. The interface definition is indeed self explanatory. Hello Aaron, Can you have a brief look at the section "C++/C# Interoperability" at the...

Re: Frequency Response Analyzer with Bode Plots

It is indeed always a challenge working cross languages, but typically all has been done before and google always has an answer... :D Does your virtual interface already run in another thread to avoid that the application freezes while connection with the signal generator is made and also when sendi...

Re: Frequency Response Analyzer with Bode Plots

So, that said, I'd like to see if anyone else is motivated to help out. Even if you don't have time or skills to create a new plugin, perhaps you could offer experience, suggestions, or a review of the plugin interface. Depending on interest I'd probably start a new thread. I have some experience i...

Re: Frequency Response Analyzer with Bode Plots

What is "my impedance viewer app"? How can I download it? You can find it here: https://www.picotech.com/support/viewtopic.php?f=131&t=14311&p=141799#p141728 Source code is available here: https://github.com/WimHuyghe/FRA-Impedance-Viewer Some more details are described earlier in this thread and h...

Re: Power Measurement/Calculation using FRA

Hi all, I need to measure the consumption power for a coil and a piezo. What is the standard way of doing this using FRA? Thanks, Vahid You mean expected power consumption at each frequency? If yes, I think the easiest way is to plot the impedance curve by using a series resistance and my impedance...

Re: Frequency Response Analyzer with Bode Plots

Just a quick update with some bugfixes: - incorrect phase was shown in impedance plot (both plot and cursor) - app did not work on X64 systems (had to force 32 bit mode for the app to make it work). @Kai, I am still planning to do the calibration, just a bit tied up for the moment, so only had time ...

Re: Frequency Response Analyzer with Bode Plots

In the meantime, if your curious, another thing you can experiment with is Noise Reject mode. Since your scope has such a large sample buffer, you can select Noise Reject mode and narrow the NR bandwidth setting and significantly increase your processing gain. I think the default is 100 Hz, but you...

Re: Frequency Response Analyzer with Bode Plots

Hi Kai, First of all many thanks for the very detailed reply (twice!). Some of it I will take a bit of reading for me to fully understand, but will definitely try to understand all details. This indeed covers much more than my original question, and will try to work something out in my app using you...

Re: Frequency Response Analyzer with Bode Plots

Hi Wim, the calculation is much easier and more clearly represented, when you do it in complex math (numbers/functions) and only changing to real and imaginary parts in the end, when you want to extract resistance and reactance or conductance and susceptance or things like tan(delta) resp. loss-fac...

Re: Frequency Response Analyzer with Bode Plots

At the EEVBlog forum I posted my calculation principle how to possibly perform a calibration of the test jig (see http://www.eevblog.com/forum/testgear/rlc-impedance-viewer-for-picoscope-bode-plot-data/msg2238570/#msg2238570) with this software. If anyone who is good with math would like to review t...
