Incorrect calculation of link
distance
Verify that the calculation tool
used and the GPS used both use
the same annotation system
(degree hours minutes seconds
or degree with a decimal value)
Antennas aligned on side
lobes
Use Visual Alignment Tool to
verify direction of antennas.
Antennas set to different
polarizations
Verify that both radios are set to
the same polarization. (see page
22)
Installed two high or low
band radios in one link
Verify that one end of the link is
high and the other end is a low
band radio (see page 22)
RSL voltage lower
then expected
Link exceeds maximum
specified range
Verify that maximum path
length has not been exceeded
Fibers are not connected Connect fiber and let radio
perform it’s auto calibration
routine (see page 29)
Antennas are not aligned for
maximum RSL
Use the Visual Alignment Tool
to verify antenna alignment.
Auto calibration not
completed
Power cycle units to force auto
calibration cycles. (see page 29)
Low link quality
voltage
Interference Check for possible interference
by turning off the radio at the
other end of the link and verify
the RSL voltage on the local
site drops below 0.2V
