15 PERFORMANCE TESTS
This section includes procedures to verify the performance of the installation’s mobile antenna system.
There are three (3) procedures in this section:
• Changing Operating Mode for Tests
• Testing by Transmitting into a Dummy Load (a 50-Ohm RF Terminator)
• Testing by Transmitting into the Mobile Antenna
The accuracy of test results depends upon a DC power source in the range of 13.6 volts
DC ±10%. The current capacity of the power source must be greater than 15 amps.
Make sure the vehicle’s battery is fully charged by running the engine for a few
minutes before the test, and keep the engine running during the test procedures. Abide
by the following WARNING!
If the vehicle’s engine must remain running, the vehicle location should be well
ventilated so exhaust fumes from the engine do not cause harm!
If a vehicle equipped with this radio requires jump-starting, the radio installation’s
main fuse should be removed from the holder prior to jump-starting. Doing so will
prevent damage to the radio system.
Prior to installation, the radio’s power level should be configured appropriately. The
wide range of power levels indicated in the
following procedures takes into account
such things as: customer’s requirements; measurement errors, especially to include
uncalibrated equipment; cabling losses; and voltage and temperature variations. By no
means should the result from Performance Testing in this section be construed as the
exact power level output from the radio, as the level
is set and more accurately
measured in the factory. The levels
obtained in these test procedures determine a
successful installation only.
