Spectrum Sweep
Use the RDL-3000 Spectrum Sweep feature to determine if RF spectrum is clear of
interference. Click
Utilities ->
Spectrum Sweep
in the left hand menu to display the
Spectrum Sweep configuration screen.
Configurable survey settings permit scanning a limited frequency range. Configurable
survey parameters include the high and low frequency limits, the step size, and the
number of samples at each step. Channel size is selected automatically based on the
current channel setting. The output graph displays the average (dark green) and
maximum (light green) RSSI measured at each step for RF port 1 & 2.

Spectrum Sweep Configuration
Start Frequency (MHz)
: Enter center frequency of the lowest channel to be scanned.
End Frequency (MHz)
: Enter center frequency of the highest channel to be scanned.
Step (MHz)
: Enter the frequency step (MHz) to use when scanning. Minimum step size
is 0.250 MHz for all radios.
No. of acquisitions
: Enter the number of times the frequency is sampled at each step.
IMPORTANT
:
Use a maximum of 100 acquisitions for each spectrum sweep.
