GS5220 Phase Microstepper
Products Introduction
The GS5220 phase micro-stepper device, also know as phase and frequency offset generator, has a built-in high stability crystal oscillator that can receive a 10MHz sine wave signal input from an external hydrogen or hp cesium atomic clock and output a high-stability, low-phase-noise frequency standard signal to improve the short-term stability of the cesium atomic clock and purify the phase noise of the hydrogen atomic clock. It can also receive an external 1PPS signal to synchronize the 1PPS signal output by the device.
The device output signal has high-precision frequency and phase modulation functions:
The FM resolution is better than 5E-19;
The phase modulation resolution is better than 1fs.
The equipment has remote monitoring capabilities, allowing customers to conveniently perform remote network time synchronization and monitoring.
Application areas
Time and frequency metering stations at all levels;
Construction of various civilian and military time and frequency systems.
Features
-
It features an external reference input function and supports GPS 1PPS 10MHz signal input;
-
It has a 1-channel external 1PPS second signal synchronization function;
-
Outputs two 10MHz signals and two 1PPS second signals;
-
It has phase and frequency modulation functions with high accuracy in both frequency and phase modulation;
-
It has a network remote status monitoring function, which makes it convenient for users to operate remotely.
