Spectrum Sweep
Click

Sweep
in the left hand menu to display the Spectrum Sweep configuration
screen. The spectrum sweep feature is an off-line RF survey tool to detect interference
and evaluate spectrum availability. Configurable survey parameters include the high and
low frequency limits, the step size, and the number of samples at each step. The output
graph displays the maximum (red) and average (blue) RSSI for each step.

Start Frequency (MHz)
: Enter center frequency of the lowest channel to be scanned.
See Table 63: Spec. - Regional Identification Codes on page 99.
End Frequency (MHz)
: Enter center frequency of the highest channel to be scanned.
See Table 63: Spec. - Regional Identification Codes on page 99.
Step (MHz)
: Enter the frequency step (MHz) to use when scanning from the lowest to
the highest frequency. The step selection must be a multiple of 2.5 MHz (i.e., 2.5, 5, etc).
No. of acquisitions
: Enter the number of times the frequency will be sampled at each
step. The recommended range is 10 to 100 samples. When a potentially clear channel is
identified, reduce the frequency range and step size while increasing the sample size to
monitor the channel over a longer period.
Start
: Left-click the Start button to begin the scan.
Performing a Sweep
The PTP Master or PMP Sector Controller transmitter is automatically disabled during
the spectrum scan. If the scan is being performed from a PTP Slave or PMP Subscriber,
the transmitter on the remote AN-80i for this link should be disabled for the duration of
the test. Use the configuration Test feature (system configuration screen) to remotely
(over-the-air) disable the remote transmitter for 5 minutes (uncheck
the Radio Enable
field) and then recover automatically.
