TRANSMITTER SUPPLEMENTAL
The Dual Port Power Sensor provides a real time analysis of the transmitted pulse and re-
verse power. Measuring both forward and reflected power from the waveguide assembly
bi-directional coupler allows for indication of the transmitted pulse and the reflected en-
ergy. Since reflected energy is also comprised of weather information, the reverse energy
is only measured during the transmitted pulse width. If a problem exists in the waveguide,
from the transmitter to the feed-horn, this reflected energy will be sensed, and depending
on the measured VSWR in the power monitor, the transmitter can be configured to shut-
down until the problem is resolved. An LCD display on the front of the power monitor
gives readouts of forward power, reverse power, both in dBm and in KiloWatts. The infor-
mation displayed on the power monitor is also fed to the DDC module for incorporation
into the BITE data stream for remote viewing. The power moniter can measure power of
RF pulses that are at least 0.4µs in width. For complete information about the various
modes of operation and in setting the user parameters please refer to EEC Publications;
Dual Port Power Monitor User Manual, and Dual Port Power Monitor ICD.
