Bit Error Rate (BER) Test
Use this test on a unit having any of the following symptoms: resets (RAAAA Type), No Service 
failures.
 
Notes:
1.
Confirm the reset log has errors.
2.
Place the unit into Test Mode for this test.
3.
Watch the unit for resetting during this procedure.
4.
Verify the R-2660 has been calibrated and cable continuity is good.
5.
In the United States, the Main board can only be replaced and 
 
programmed at the factory or iDEN Radio Support Center.
6.
The Power, MPX, and MOD test parameters are for factory use 
only and should not be adjusted by field service personnel (see page 
7-2
 
for default values).
Fail
Unit passed test. Look for system, cover-
age, accessory, or software problems.
Fail
Press Start
on unit. Press TX ON. The
RX BER that appears on the display
should be 0.0% at -70 dBm. Verify that
the TX BER on the R-2660
is < 0.07%.
Pass
Connect the battery eliminator to the 
unit. Remove the antenna. Set power 
supply between 5.0 and 12.0 Vdc.
Power up the unit. Enter Test Mode.
 
Do the following:
 
   1. Press the Menu key, and then the Edit option key.
   2. Press the Change option key, and scroll down to 800BER1.
   3. Press Select to select the test.
   4. Press the Back key, and then press Menu.
Fail
Pass
Lower
Gen: to -109 dBm
and check the RX BER in the
display. The BER should be less than 10% 
when at Gen: -109 dBm. (Freq
Error should be less
than 200 Hz.)
Set up the R-2660 for iDEN BER 
Test, and connect the unit to the RF 
IN/OUT connector.
Replace the
Main board, and 
repeat the test.
Replace the
Main board, and 
repeat the test.
Replace the
Main board, and 
repeat the test.
The monitor frequency is 806.0125 
(Carr#1) for BER1.
Pass
Repeat the
above test using
800BER2, 800BER3,
800BER4; 900BER1, 900BER2,
and 900BER3 in Test Mode. 
The monitor frequency is 813.5125
(Carr#601) for 800BER2820.9875 (Carr#1199)
for 800BER3, and 824.9875 for 800BER4
The monitor frequency is 896.01875 for
900BER1898.51875 for
900BER2 and
900.98125 for
900BER3.
Note: Ensure that the maximum cable 
loss does not exceed 2 dB.
Note: Change offset on R2660 to +39 MHz for 900 
MHz (900BER1, 900BER2, and 900BER3).
