#132 In this video I continue looking at how quartz crystal oscillator specific measurements can be performed, and today its time for drive level. Since this measurement involved measuring quite a small current, ideally using a small current probe, first task is to make the current probe. Then I proceed to perform some measurements on an oscillator and adjust the components and settings until the drive level requirements are met.
