The GPSDO (Global Positioning System Disciplined Oscillator), also known as a GPS disciplined cryogenic crystal oscillator, GPS disciplined clock, or 10MHz standard signal source, offers higher accuracy, lower temperature drift, and more stable output compared to ordinary time bases. Applicable Scenarios: GPSDO is widely applicable to high-end audio decoders, instruments, meters, frequency counters, signal generators, and other equipment with time accuracy requirements. It provides these devices with a stable and reliable 10MHz reference source input, ensuring the accuracy and reliability of equipment operation.
