RF Scanning: Design and Resolution
The design of the Spectrum Manager supports wideband frequency scanning over the UHF band. Eight parallel receivers
and three selectable detector bandwidth options (1MHz, 200kHz, 25kHz) available in Wireless Workbench enable very
fast frequency scanning in just a few seconds. If used without Wireless Workbench, the Spectrum Manager selects the
200kHz bandwidth (RBW) filter to closely emulate the receiver filter response.
Below is an example of a RF plot of the spectrum illustrating the 1MHz, 200kHz, and 25kHz filter bandwidths. The 1MHz
scan provides faster scan times at a lower resolution, while the 25kHz scan increases resolution by 25 dB allowing you to
zoom in on a section of frequencies with increased dynamic range.
When performing a frequency plot in Wireless Workbench, the eight independent parallel receivers inside the Spectrum
Manager divide up the UHF frequency range into eight sections for faster scanning. Multi-band scanning is also available
from the menu of the Spectrum Manager as described in a later section of this chapter.
