Frequency (MHz): Center frequency of the scanned channel.
Ave (dBm): Average measured signal for all samples.
Max (dBm): Maximum measured signal for all samples.
Bar Graph: Graph of average (dark green) and peak (light green) results.

Performing a Sweep

Prepare the RDL-3000:
1.
For PMP sector controllers, the transmitter is disabled automatically during a sweep.
Note: To run a sweep from a PMP Subscriber location, the sector controller
transmitter must be disabled for the duration of the test.
Click Wireless
2.
the smallest available channel with a step size of 1/2 the planned channel size (e.g.,
use a 5 MHz step size when scanning for a free 10 MHz channel). For example:
Start/Stop = 5735 / 5830
Step [MHz] = 5
No. of Acquisitions = 10
Click Start button to begin the sweep.
3.
Review the results. A channel is 'clear' when free of interference for at least +/- one-
4.
half the channel bandwidth from the desired center frequency. For example, a 20
MHz channel should have no interference detected for at least +/- 10 MHz from the
candidate channel.
When a clear channel is identified, reduce the frequency range and step size while
increasing the sample size to monitor the channel over a longer period.
