Hi all,
I am measuring RTC crystal frequency of 32.768kHz using a 300MHz scope.
I am connecting the scope ground to my board ground. And using one channel I am probing the crystal pins.
For the first two times, I measured and I got the sine wave of the mentioned frequency.
But aftersometime, I tried to measure, I am not getting the sine wave. I am just getting a DC level shift of 100mV when I probe the crystal pins.
What could be the potential problem? Am I doing something wrong while measuring?
Please help.
Thanks.
