Frequency Response Analyzer with Bode Plots

[stereovintage]

Hi Aaron,

After a few weeks of testing some 2406B, i encountered a problem with the FRA4PicoScope application.
Although we have installed the SDK32 bit, the application keeps giving the same error "Signal generator plugin not configured".

We tested it on different PCs with Win 7, Win 10 and Win 11 and encountered the same problem.
I attach files with screenshots: https://1drv.ms/b/s!AjcChqVMGWQ6iqok-RQ ... g?e=C6yKJl

Thank you,
Fabio

Hi Fabio,

I think I know what's going on and can help.

1) Firstly, the external signal generator option (File->Connect Signal Generator) is probably not relevant for you since you have a PS2406B which has a signal generator. That feature is for scopes without a signal generator or where you need to use an external signal generator with greater capability than the one built into the scope. And to use it you need to have developed or acquired a plugin. To date, I know of no one besides myself that's done that

2) I think the problem your experiencing is that with the default settings (start frequency = 1 Hz, low noise mode with 16 cycles), the initial step of the FRA can take at least 16 seconds. And it can take even longer depending on the circuit and auto-ranging. Maybe it looks to you like the application is doing nothing and so you cancel? If you want to get more frequently updated info on what's going on, go into the verbosity settings (Tools -> Settings -> Log Verbosity) and turn on things like Step Trial Progress and Sample Processing Diagnostics.

Thanks,

Aaron.

Hi Aaron,

in the meantime, thanks for the useful and accurate information you provided me!
As you had guessed, the problem of not starting the Plots was due to the fact that i stopped the operation after about 30-45 seconds.
I noticed that on the first start the minimum time on this PC is about 55 seconds.

I also wanted to ask if there is a setting to set the x scale of the frequency in linear?

Thank you,
Fabio
