Link Verification
Verify that the Received Signal Level (RSL) is up to +/- 4 dB from
the expected (calculated) level at both ends of the link.
You can measure the RSL at the BNC port indicated in the figure
to the left. The voltage at the BNC port is 1.XX where XX is the
RSL level. For example: 1.59V means an RSL of -59 dBm. Note
that the voltage measured at the BNC port is not accurate and
should be used only as an aid).
Verify that the Radio Bit Error Rate (BER) is 10E-11 or higher.
If working with ATPC, verify that ATPC is operating as expected
(RSL = reference level).
To display the BER using the Web EMS,
go to the Aggregate PM report (
Radio >
PM & Statistics > Aggregate
).
To display the current RSL (RX)
using the Web EMS, go to the
Radio Parameters page (
Radio >
Radio Parameters
).
To display the RSL PMs using the Web
EMS, go to the Radio Parameters page
(
Radio > PM & Statistics > Signal Level
).
