TCXO (Temperature-Compensated Crystal Oscillator)
The built-in TCXO provides excellent frequency stability and accuracy by compensating for temperature fluctuations. This helps maintain consistent and reliable signal reception across a wide range of operating temperatures.
By minimizing frequency drift over time, the TCXO also helps maintain long-term frequency stability and reliable RF performance, reducing the risk of signal degradation.
