@zzz555 The clock signal may be operating at a speed outside the bandwidth of your oscilloscope. Check the Hz setting of your clock, and ensure it is less than the bandwidth of the oscilloscope (likely 100 MHz).

If it is higher, then the signal will be attenuated. Configure the scope to be AC-coupled and try increasing the scope gain to see a faint signal.
