Hello,

TIM2 kernel clock is generated from APB1:

From the reference manual:

In CubeMx:

That clock is devided with the timer prescaler

You can check the clock and prescaler in STM32CubeIDE.

Divide it down and have in Toggle mode one of the TIMx_CHx pins associated with it.and measure it on a scope?

The clock tree should be usable to determine the base frequency.
