  • In this video, I walk you through how to precisely tune and calibrate a 10MHz OCXO (Oven Controlled Crystal Oscillator) using a GPS module as a reference signal.
    You’ll also see how to compare the OCXO’s output with a GPS reference signal on an oscilloscope, how jitter can affect your calibration.
    I also show how to inject 10MHz into Si5351, to generate other frequencies like 50MHz or 100MHz, all synced to the GPS signal.
    Lastly, I give a sneak peek into how my DIY GPSDO (GPS Disciplined Oscillator) works, explaining the phase-lock loop (PLL) works.
    Whether you’re an electronics enthusiast, a DIYer, or someone looking to improve their frequency accuracy, this video will provide you with the tips and techniques you need to calibrate oscillators with professional-level precision.
