Hello

Square 32khz measurement is inaccurate.
Is it possible to have a faulty instrument ?

I've made the probe compensation, but haven't used it.

There is a similar error with a 555 timer ic.
Good at low sample speed.
There is an error at a higher sample speed.
Timer ic input voltage 8.00 v



What else can be a problem if the instrument is correct ?

In the second picture, please set acquire->acquisition->peak detect, and take a picture to upload.
In the first picture, please set the volt/div to 2V and turn the capacitance on the probe to flatten square wave. Now test the fourth picture signal.
