Passive CPD Radar
Passive CPD Radar uses existing Analog, QAM
and OFDM signals to determine the presence of
CPD. When selecting “Passive CPD radar” from the
main menu you are presented with three options.
Standard fixed BW 8-16 MHz
This is the
selection most likely used. Although you can
adjust upper and lower frequency limits, this
selection captures CPD at 12 MHz ± 4 MHz.
Narrow adjustable BW 4 MHz
. This option
provides a fixed 4 MHz BW, but the center
frequency can be adjusted from 8 to 90 MHz.
Wide BW 5-100 MHz
. This selection detects
CPD using in the complete 5-100 MHz Return
Band.
While using CPD radar with a Quiver XT you have the option to operate in either
local or headend mode. In local mode the distance to the CPD source is displayed as
described above. In headend view mode, the Quiver shows the CPD as the distance
seen from the fiber node, as measured by the Hunter system at the headend. The
Headend mode feature is not available on the unbundled Quiver XT-UB.
The radar is equipped with Max Noise Suppression function that helps in revealing
the CPD peaks from the higher than average noise floors.
