Chapter 6 Adjustment
Make sure that all the equipments are grounded completely
before test/adjustment!
Make sure that the antenna connector is correctly connected
to the equipment or load.
The output of the transmitter must connect to the standard
signal source/cymometer/deviation meter/frequency spectrum
meter with the RF power attenuator！
Make sure that the receiver does not transmit when tested!
Make sure that the engineers and the equipments have the
reliable anti-static measurement during the
adjustment/test/maintenance.
6.1 Equipments and Software Needed for the Adjustment
The following table lists the equipments and software needed for
the adjustment and test.
