5.6.5 BDR/MDR RECEIVER TEST SETUP
Referring to Figure 5-10, perform the following for the BDR Receiver Test Setup.
Note: This test requires the use of a fully functional MDR.
1. Place MDR and BDR power switches to the
OFF
position.
2. Place a 20 dB power attenuator on the BDR
ANTENNA
port. Place an
additional 20 dB of attenuation to the power attenuator attached to the BDR.
Connect a 20 dB power attenuator to the MDR at the
ANTENNA
port. Place an
additional 20 dB of attenuation to the power attenuator attached to the MDR
3. Connect a N cable from the BDR attenuator to the MDR’s attenuator.
4. Connect a PC to each radio with diagnostic cables at the radio
DIAGNOSTIC
ports
5. Connect power to the units. Place the MDR and BDR power switches to the
ON position and bring up the Diagnostic LCP screen. Refer to section 2.5.2 for
details.
6. After the MDR LCP menu appears, select command #28 (Status Request).
Record the Transmit and Receive PN Code Indices.
7. On the BDR LCP menu, set the Transmit PN code index equal to the MDR
Receive PN code index recorded above. The code is set as follows from the
BDR LCP menu.
2 ↵

On the BDR LCP menu, set the Receive PN code index equal to the MDR
Transmit PN code index recorded above. The code is set as follows from the
BDR LCP menu.

8. On the BDR LCP menu, select command #28 (Status Request). Verify that the
Upper, Lower, and Lower Lock Thresholds are the same as written on the
configuration sheet shipped with the radio.
9. On both the MDR and BDR LCP terminals, select command #33 (Set dBm
output level.) Set each radio transmitter output level to 24 dBm.
10. At the MDR LCP menu, select command #16 (Enable Transmitter).
11. Verify that the BDR
RECEIVER LOCK
light is on. If it fails to illuminate, the
BDR is not operational.
12. At the BDR LCP menu, select command #16 (Enable Transmitter.)
13. Verify that the MDR RECEIVER LOCK light is on. If it fails to illuminate, the
BDR is not operational.
14. If both
RECEIVER LOCK
lights are illuminated, either the BDR was not
configured correctly (i.e. PN code indices) prior to this test, the antenna
connection was faulty, or the factory should be contacted for further
