SPEED SIMULATION TEST: The G3™ verifies the speed accuracy
using synthesized Doppler frequencies corresponding to
a series of simulated speeds: A patrol speed of 50 and a target speed
of 65 (when in mph mode) and 80 and 104 (when in km/h mode).
9.2 Tuning Fork Test
In addition to the system test, you can verify signal processing
accuracy with a tuning fork. Test your G3™ with two tuning
forks—a high and low speed fork. Each fork is labeled with which
antenna to test with it.
Figure 9.2a
Place the vibrating tuning fork about three inches in front of the antenna.
9.3 Tuning Fork Test Using a VIP ™
If you are using the optional VIP then for vehicles using a 12 VDC
cigar plug wired directly to the battery, turn off the vehicle (key in
the OFF position) and perform the standard tuning fork test. (With
the vehicle turned off, the VIP™ is not receiving information from the
vehicle’s Diagnostic Port and therefore the VIP™ will not interfere with
the tuning f or k t est . )
For vehicles using a 12 VDC cigar plug activated through the ignition,
unplug the VIP™ from the radar unit before performing the tuning
fork test.
