Model:ZHCGPS-FM8

Specifications:--

Price:$2350

Introduce:ZHCGPS-FM8 digital standard frequency generator is a high-performance, high stability generator by digital control with GPS locked. This standard frequency generator can simultaneously track 12 satellites, and choose the best satellite locked according to the spatial position and the satellite signal quality; the standard frequency generator has a self-learning function, after more than 24 hours of training (GPS lock operation), when the GPS off, it still can maintain long-term stability and 1PPS output signal frequency. LCD screen can be viewed by satellite parameters, frequency locking status and other control parameters, the operator can set the GPS lock key parameters and output parameters to optimize the frequency control and optimization GPS locking and 1PPS frequency output. This digital standard frequency generator with its superior performance can be widely used for timing synchronization demanding fields such as telecommunications, radio & TV broadcasting station.

1. Introduction

ZHCGPS-FM8 digital standard frequency generator is a high-performance, high stability generator by digital control with GPS locked. This standard frequency generator can simultaneously track 12 satellites, and choose the best satellite locked according to the spatial position and the satellite signal quality; the standard frequency generator has a self-learning function, after more than 24 hours of training (GPS lock operation), when the GPS off, it still can maintain long-term stability and 1PPS output signal frequency. LCD screen can be viewed by satellite parameters, frequency locking status and other control parameters, the operator can set the GPS lock key parameters and output parameters to optimize the frequency control and optimization GPS locking and 1PPS frequency output. This digital standard frequency generator with its superior performance can be widely used for timing synchronization demanding fields such as telecommunications, radio & TV broadcasting station.

 


ZHCGPS-FM8 digital standard frequency generator main features:

  ZHCGPS-FM8 digital standard frequency generator can continuously track 12 satellites simultaneously and choose the best satellite locked according to the spatial position of the satellite and signal quality. It provides high performance and high stability 1PPS, 10MHz, 24.32MHz, 327.68MHz and 655.36MHz output, frequency stability up to 1.2 × 10-12 with low phase noise.

  ZHCGPS-FM8 digital standard frequency generator uses a Kalman filter to achieve self-learning function, when GPS signal cut off, it will into auto-hold function and automatic recovery function of GPS signal re-locked.

  ZHCGPS-FM8 digital standard frequency generator can set GPS lock parameters and 10MHz reference clock source for controlling parameter and setting adjustments.

  ZHCGPS-FM8 digital standard frequency generator receiving antenna length compensation.

  ZHCGPS-FM8 digital standard frequency generator real-time monitoring of satellite-related information, the frequency of the locked state and the reference clock source control parameters.
