32Mhz external clock on osilloscope

[Oguzhann]

Hello everyone,

I have questions. I am trying to scope 32mhz external clock on osilloscope that gwınstek gds-1062 and I show this two picture. First is at 250ms time/div. I think every advertising interval(450ms) the mcu is triggered and then go to low and non-oscilate state. 

Second is at 10ns time/div to show period of 32mhz signal but i can not see. I think correct or else. Can you help me?

Hi Oguzhann,

Are you trying to see the crystal oscillations on the scope? And are you trying to do so by looking into the short time that the radio is active?

If yourmain goal is to see the crystal oscillations, I think you are better off setting up an application that request the external crystal and high frequency clock, rather than trying to catch the short radio activity interval.

my main goal was to observe the oscillations of hfxo. however, according to my observations, there is an oscillation at 450 ms and the rest of the time it goes into low mode and is not triggered.

If you want to observe the oscillations of HFXO, then you should try to request HFXO in your application like I mentioned before.

what is the difference from standart clock operation?

Please go over the documentation for clock management. HFXO is only turned on upon request and is switched off automatically after the requester releases it.
