Q&A:

Q: What is the difference between OCK-2S and OCK-2P?

A:Both are 10 MHz OCXO master clocks. OCK-2P is an upgraded version of OCK-2S, offering:

• A higher-precision OCXO with lower phase noise (< -115 dBc vs. < -110 dBc)
• Improved internal circuit and power supply design
• Enhanced chassis and internal isolation structure

OCK-2P focuses on further refinement in stability, detail, and timing accuracy, while OCK-2S already delivers excellent core performance.

Q: What is the purpose of the Float / Ground switch?
A: If multiple devices are grounded, a ground loop can occur and cause hum or noise. Switching one device to Float breaks the loop and helps reduce or eliminate the noise.
