LHY AUDIO UCCM GPS Disciplined Oscillator GPSDO 10MHz Frequency Standard + Power Adapter + Antenna

Description:
This GPSDO adopts the original UCCM (Universal Center Clock Module) for Samsung, featuring fast lock time, high sensitivity, strong frequency stability, and low phase noise. It is ideal as a clock source for high-end HiFi audio equipment or as a frequency reference in laboratory settings.

Improve Accuracy and Stability & Ensure Time Consistency Across Systems:
* Fast Locking
* High Accuracy
* High Stability
* UCCM OCXO Module for Samsung
* Near-End Phase Noise -100dBc at 1Hz
* Frequency Accuracy: 0.001ppb
* 2 Independent and Isolated Output Channels

Core Module and Performance Features:
The internal core is a second-hand UCCM module, originally integrated into high-end communication equipment. Due to equipment upgrades, the UCCM module was removed and sold separately at a price much lower than new ones. It uses UC-CM-LPQ module for Samsung version. And it includes the built-in STP2878 OCXO and the LEA-6T GPS receiver module for uBlox. Its overall performance is as follows:

* GPS Locked 24-hour Average Accuracy: 1×10⁻¹², equivalent to 10.000 000 000 01 MHz, with an accuracy of 0.000001ppm (0.001ppb).
* When GPS is not connected: Maintains an accuracy of 1×10⁻¹â°.
* Phase Noise: Better than -100dBc at 1Hz offset.
* Allen Variance: <1e-12 at 1s.

Connection and Monitoring:
The UCCM module supports connection to a computer via an RS232 serial port. Users can monitor the status and configure parameters using terminal software or the GPS monitoring software Lady Heather. Information that can be viewed includes UTC time, satellite signal strength, PPS time quality, and frequency quality.

Usage Recommendations:
* Antenna Position: Ensure the antenna can receive signals from at least 50% of the sky, and it is best to install it in an open area (such as a rooftop).
* Power-On Time: To improve frequency accuracy, it is recommended to use the GPSDO device with continuous power for extended periods.
* Audio Use: After connecting the GPS antenna and powering on for more than 24 hours, the GPS antenna can be disconnected and the device can continue to be used.
* Module Status: Although the UCCM module is a second-hand component, it has been fully tested to ensure its performance is normal.
