6.7 SPEEDOMETER INPUT SYNCHRONIZATION
The initial use of the Directional Golden Eagle II with
speedometer pulse input requires the radar unit to be
synchronized with the speedometer.
1. After installation and initial testing with tuning forks,
the Directional Golden Eagle II should be driven at a
constant speed between 30 and 70 MPH (48 and 112
km/h). Depress the PAT-SET switch on the front panel
twice. “Snc” will appear in the TARGET window and
Doppler patrol speed will appear in the PATROL
window.
2. Verify the patrol speedometer and the Doppler patrol
speed displayed agree within reasonable limits, and then
depress and release the Lock/Release switch. This tells
the DSP processor that the current speedometer pulses
(speed) and the Doppler patrol signal (radar patrol
speed) agree.
After approximately one second, a number will briefly
appear in the LOCK window. For Ford Motor Company
vehicles, this synchronization number will be around 34.
This indicates the unit
is reading and comparing the
speedometer pulses and the Doppler patrol signal.
NOTE: Only the actual radar Doppler signal is used
for patrol speed. The speedometer pulse input
is used only to steer or guide the DSP to “look”
for the patrol Doppler signal in a specific area,
ignoring other signals.
