This article explores the challenges and solutions related to temperature drift in field deployment of Low Power Oven Controlled Crystal Oscillators (OCXOs) for seismic monitoring systems. It explains the concept of temperature drift and highlights protective strategies such as thermal insulation, d... read more

The frequency-temperature characteristic of an OCXO is engineered to minimize frequency drift caused by ambient temperature changes. By maintaining the crystal at a constant temperature inside a mini-oven, OCXO typically achieve ±1 to ±10 ppb stability across a wide range (-40°C to +85°C). However, ... read more

This technical note details the standard temperature set point for an OCXO's internal oven, typically between 75°C and 85°C. This is set approximately 10°C above the upper ambient operating limit to guarantee a stable environment for the crystal, ensuring exceptional frequency stability. The article... read more
