Precise timing reference: The GPSDO uses a GPS 1PPS signal to discipline its output frequency, delivering a stable and accurate timing reference for applications requiring precise synchronization. Temperature stability: A temperaturecontrolled oscillator minimizes frequency drift, ensuring consistent performance across environmental conditions important for electronic measurements and equipment. Seamless connectivity: Multiple output interfaces, including 10 MHz and 1 PPS, allow easy integration with end audio decoders, frequency counters, and other timingsensitive gear. Compact design: Measuring 150 x 88 x 38 mm, the GPSDO fits easily into compact lab benches and field setups without occupying excessive space. Applications Laboratory timing and synchronization: Provides a stable reference for oscilloscopes, spectrum analyzers, and data acquisition systems to improve measurement accuracy and repeatability. end audio and video systems: Serves as a precise clock source for audio decoders and DACs, helping minimize jitter and timing errors in critical systems. Field measurements and remote deployments: Delivers a GPSdisciplined time and frequency reference for counters, analyzers, and data loggers in portable or remote environments.
