Im seeing a pattern on my scope but no clock display. What is wrong?
Make sure your scope is in X-Y mode and that the proper Vertical Mode is selected. On many Tektronix scopes this is the CH2 Vertical Mode. Also double check the probe connections, as well as their Ground. The CH1 and CH2 terminals are very sensitive to any kind of noise. Just touch them with your fingers while the clock is running.
