Procedure 3
Antenna Check
Check 1
Use an antenna test cable to check the antennas' connection. Follow the steps
below:
1.
Remove the Bluetooth slot cover and lift it off. Refer to Chapter 4,
Replacement Procedures
, for detailed steps of disassembling.
2.
Disconnect the Bluetooth antenna cable connected to the Bluetooth module.
3.
Connect the end of the antenna test cable to the multimeter.
4.
Connect the Bluetooth antenna cable to the antenna test cable. One clip is
connected to the end of the Bluetooth antenna cable. The other is connected to
the opposite side of the Bluetooth antenna cable.
5.
Determine the resistance. The cable passes the test when the resistance is less
than 5
Ω
. If it is more than 5
Ω
, the Bluetooth antenna cable fails the test.
Figure 2-3 Antenna Test cable
NOTE
: 1.
The resistances determined with the steps above may not be stable with other
machines because of "cable loss," which varies according to the length of the
cable. The impedance of the antenna itself is about 0.5-0.8 ohm.
2.
The above steps cannot accurately determine the impedance of the antenna.
Use an LC meter for a precise measure of impedance.
If the Bluetooth antenna cable pass the test, connect it to the Bluetooth module and cover the
slo t, then perform Procedure 1.
If the Bluetooth antenna cable does not pass the test, go to Procedure 4.
