Hello all,

I'm using Stimulus&Probe to check the frequency response on ADAU1701, it works correctly when i click Probe button at the first time.

but after closed the response window and click probe button again, nothing displayed.

if i reopen the project and try again, it also works just once.

I build the project acc.to the insturction Probe and Stimulus Blocks [Analog Devices Wiki],

i have no idea about the reason. attached is the project.Probe.zip

Appreciate for the help.Thanks.

Hi Eason,

Thank you for attaching your project, this saves us time. I tried the project as well as some of my own, with ver. 4.7 and older SigmaStudio revs, on both Windows 11 and 10. Each behaved as you described -- the graph(s) disappear along with the window. I haven't noticed this before simply because rather than close my Probe windows, I usually just slide them out of the way. Thus, I conclude that your experience is quite normal behavior.

If you do close the Probe window, you need not quit and reopen the project to restore the graphs -- just click the Stimulus button(s) once again.

Best regards,

Bob

Hi Bob,

Thanks for your quick response and help.

Acc.to the verification on your side, i will slide it out of the way instead of closing it.

I have tried to click the Stimulus buttons again after closed the Probe window, but the phenomenon is diferent with the experience as you decribed, no window popup. My operation was:

1. close Probe window.

2. Click Stimulus1 button and Stimulus2 button.

after the operation above, no window popup, then clicked Probe button, the window popup without graph.

So i was confused about the different performance. Hope for the clarification from you. Thanks.

Best regards.

Hello Eason,

Sorry for the confusion. Try this order of steps to restore the graphs:

Begin with the Probe window closed.

Click on the Probe button to re-open the Probe window.

Then, click the Stimulus button(s) to fill in the graph(s).

The graphs should again respond to your EQ sliders.

If you close the Probe window -- repeat Steps 2 -- 4 when re-opening it.

Hope this helps.

Bob
