Spectrum Sweep

Click Spectrum 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 lowest frequency to be scanned. See Table 1: Web
- RF Channel Range.
End Frequency (MHz): Enter highest frequency to be scanned. See Table 1: Web
- RF Channel Range.
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, 7.5, 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 transmitter of the PTP Master AN-80i is automatically disabled during the
spectrum scan. If the scan is being performed from a PTP Slave AN-80i, the
transmitter on the remote AN-80i for this link should be disabled during the test.
You can use the configuration test feature to remotely (over-the-air) shut down the
remote transmitter for 5 minutes and then recover automatically. See the
description of the Test button in section 3.5: System Configuration Screen under
the heading Controls on page 26.
