Test Equipment Required for Alignment
*The test equipment which is not used for adjustment is contained in this table.
Antenna connector adapter
The antenna connector of this transceiver uses an SMA termi-
nal.
Use an antenna connector adapter [SMA(f) - BNC(f) or SMA(f)
- N(f)] for adjustment. (The adapter is not provided as an op-
tion, so buy a commercially-available one.)
Repair Jig (Chassis)
Use jig (Chassis) for repairing the transceiver. Place the Main
unit on the jig and fit it with screws.
The jig facilitates the voltage check and protects the final am-
plifier FET when the voltage on the flow side of the Main unit
is checked during repairs.
Battery Jig (W05-1011-00)
Connect the power cable properly between the battery jig in-
stalled in the transceiver and the power supply, and be sure
output voltage and the power supply polarity prior to switching
the power supply ON, otherwise over voltage and reverse con-
nection may damage the transceiver, or the power supply or
both.
Note:
When using the battery jig, you must measure the voltage at
the terminals of the battery jig. Otherwise, a slight voltage
drop may occur within the power cable, between the power
supply and the battery jig, especially while the transceiver
transmits.
