Data Acquisition Interface
8112777 (9631-10)
The Data Acquisition Interface is a compact module designed to
be installed into one of the slots on the RTM of the Radar
Processor/Display. This module receives the I- and Q-channel
echo signals of the radar, perturbed or not, and converts them to
digital format. It also receives the PRF and synchronization
signals as well as azimuth information from the Radar
Synchronizer / Antenna Controller. All these signals are then
routed to the RTM for digital signal processing.
The Data Acquisition Interface has two BNC-connector analog
inputs to receive the I- and Q-channel echo signals. It also has
two BNC-connector digital inputs where the PRF and
synchronization signals are injected. A DB15 connector is
provided as a digital input for the azimuth information. All these
inputs are protected from misconnections within the system.
Test points are available on the module's front panel to observe
the input signals using a conventional oscilloscope.
DC power is automatically supplied to the Data Acquisition Interface when it is installed into the RTM.
