Sync Location = 276 264 258
Sync. Amplitude = 131070 131070 131070
Total Bits = 2592 2592 2592
Bits in Error = 0 0 0
BER (%) = 0.0000000000 0.0000000000 0.0000000000
RSSI (dBm) = -96 -97 -96
12 For each receiver branch, calculate the difference between -100 dBm and measured RSSI level
using the following formula:
RX<receiver branch number> delta = -100-(-<RSSI (dBm) measured level>)
Step example:
RX1 delta : -100-(-96) = -4
RX2 delta: -100-(-97) = -3
RX3 delta: -100-(-96) = -4
13 Set the RSSI calibration values using the results from step 12 using the following command:
fcp -orxch1 -pcal_br<receiver number> -v<calculated calibration value>
Step example:
fcp -orxch1 -pcal_br1 -v-4
fcp -orxch1 -pcal_br2 -v-3
fcp -orxch1 -pcal_br3 -v-4
NOTICE: RSSI calibration is not operational before the BR is reset.
14 Repeat step 2 and then step 5 through step 13 for all branches until the RSSI level is correctly
calibrated for all branches.
15 Reset the BR. Use the following commands:
sge -orx_all -soff
reset -ocontrol
16 Verify RSSI for receive path 1, 2, and 3. Type ppr -orxch1 -a10 -r1
The following example shows a correctly calibrated RSSI level for all 3 receive paths.
Step example:
Receiver Number = 1 2 3
SGC Attenuation = 26214 26214 26214
Sync Location = 276 264 258
Sync. Amplitude = 131070 131070 131070
Total Bits = 2592 2592 2592
Bits in Error = 0 0 0
BER (%) = 0.0000000000 0.0000000000 0.0000000000
RSSI (dBm) = -100 -100 -101
Postrequisites: BR-Arch-2 only: Verify and tune the receivers for the high power setting. See
Verifying and Tuning the Receiver RSSI Levels in a High Power Setting for BR-Arch-2 on page 268.
6.5.4.3.4
Verifying and Tuning the Receiver RSSI Levels in a High Power Setting for BR-
Arch-2
Receivers in BR-Arch-2 can work with two different power levels and require additional actions to fully
configure their RSSI levels. Perform this procedure only in BR-Arch-2 architecture.
