Crystal tester circuit
WebCrystal Tester¶. Quartz crystals can be used to create very accurate, stable, and low-cost crystal oscillators.They are usually specified in terms of parts per million (ppm): a 1 ppm crystal of 1 MHz has a frequency deviation of ≈ 1 Hz. That’s like walking for 1 km and stopping to within exactly 1 mm.. I have many crystals, both salvaged and purchased. WebOct 20, 2024 · It is interesting that because of the resonance of the crystal, the voltage on the scope can be much higher than the input voltage from the signal generator. This is a …
