5.5 Spectrum Sweep Screen
5.5.1 Overview
Use the AN-80i Spectrum Sweep feature to determine if RF spectrum is free from
interference. Configurable survey settings allow you to scan a specific frequency range -
- specifying both the step size and the number of samples at each step. When the
sweep is completed, an output graph displays the average (blue) and maximum (red)
RSSI measured at each sample step.
Click Spectrum Sweep in the left hand menu to display the Spectrum Sweep
configuration screen. 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 73: Spec. - Regional Identification Codes on page 144.
End Frequency (MHz): Enter center frequency of the highest channel to be scanned.
See Table 73: Spec. - Regional Identification Codes on page 144.
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 (e.g., 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.
5.5.2 Example: Performing a Sweep
1. Prepare the AN-80i:
For PTP Masters or PMP Sector Controllers, t he transmitter is automatically
disabled during the sweep.
To run a sweep from a PTP Slave or PMP Subscriber location, the remote unit
transmitter must be disabled for the duration of the test.
