FMUSER GPS-FM8 Digital Standard Frequency Generator
1. Introduction
FMUSER GPS-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.
FMUSER GPS-FM8 digital standard frequency generator main features:
FMUSER GPS-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.
FMUSER GPS-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.
FMUSER GPS-FM8 digital standard frequency generator can set GPS lock parameters and 10MHz reference clock source for controlling parameter and setting adjustments.
FMUSER GPS-FM8 digital standard frequency generator receiving antenna length compensation.
FMUSER GPS-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.

How far(long) the transmitter cover?
The transmission range depends on many factors. The true distance is based on the antenna installing height , antenna gain, using environment like building and other obstructions , sensitivity of the receiver, antenna of the receiver . Installing antenna more high and using in the countryside , the distance will much more far.
EXAMPLE 5W FM Transmitter use in the city and hometown:
I have a USA customer use 5W fm transmitter with GP antenna in his hometown ,and he test it with a car, it cover 10km(6.21mile).
I test the 5W fm transmitter with GP antenna in my hometown ,it cover about 2km(1.24mile).
I test the 5W fm transmitter with GP antenna in Guangzhou city ,it cover about only 300meter(984ft).
Below are the approximate range of different power FM Transmitters. ( The range is diameter )
0.1W ~ 5W FM Transmitter ：100M ~1KM
5W ~15W FM Ttransmitter : 1KM ~ 3KM
15W ~ 80W FM Transmitter : 3KM ~10KM
80W ~500W FM Transmitter : 10KM ~30KM
500W ~1000W FM Transmitter : 30KM ~ 50KM
1KW ~ 2KW FM Transmitter : 50KM ~100KM
2KW ~5KW FM Transmitter : 100KM ~150KM
5KW ~10KW FM Transmitter : 150KM ~200KM
