Radar Training System, LabVolt Series
© Festo Didactic 36
Direct CW Doppler and FM-CW outputs are provided. Quadrature detection (I- and Q-channel outputs) is used
for the pulse radar. Wideband amplifiers are used in the I- and Q-channels to ensure faithful baseband
reproduction of the received RF signals.
Unregulated DC power is automatically supplied to the Radar Receiver through self-aligning connectors when it
is installed on the Power Supply / Antenna Motor Driver.

Analog/Digital Signal Combiner
8112776 (9630-10)
The Analog/Digital Signal Combiner is a compact module
designed to be installed into one of the slots on the RTM of the
Radar Processor/Display. This module converts the clutter and
interference generated by the DSP of the RTM to analog format,
and adds it to the I- and Q-channel echo signals coming from the
Radar Receiver.
The Analog/Digital Signal Combiner has two BNC-connector
inputs to receive the I- and Q-channel echo signals. It also has
four BNC-connector outputs. Two outputs provide the clutter and
interference signals added to the I- and Q-channel echo signals.
The other two outputs provide the I- and Q-channel, perturbed
echo signals. All these inputs and outputs are protected from
misconnections within the system. Test points are available on
the module's front panel to observe all these signals using a
conventional oscilloscope.
DC power is automatically supplied to the Analog/Digital Signal Combiner when it is installed into the RTM.
