Frequently Asked Questions

Q: What is an OCXO and why is it more stable than a standard crystal oscillator?

A: An OCXO (Oven-Controlled Crystal Oscillator) maintains the crystal at a precisely controlled constant temperature using an internal heating element. This eliminates frequency drift caused by ambient temperature changes, resulting in significantly higher frequency stability compared to standard TCXOs or XOs — making it ideal for precision reference clock applications.

Q: What type of power supply does this 10MHz OCXO board require?

A: This OCXO board is powered via a TYPE-C USB connector, making it easy to power from a standard USB adapter, power bank, or lab supply with a Type-C output. The onboard RF-specific LDO ensures the oscillator receives clean, regulated voltage for stable operation.

Q: Can this board drive a 50-ohm load directly?

A: Yes. The onboard driver IC is specifically designed to drive a 50-ohm load, which is the standard impedance for most RF and test equipment — including spectrum analyzers, frequency counters, and SDR (Software Defined Radio) receivers.

Q: What is the difference between the sinewave and square wave outputs on this board?

A: The sinewave output (10MHz / 3 dBm, 1Vpp) passes through a 7th-order elliptical low-pass filter for a clean, low-harmonic signal, ideal for frequency reference and RF applications. The square wave output (10MHz / 13 dBm) provides a stronger, logic-compatible clock signal suitable for driving digital circuits and counters.
