Dual-Channel Sampler
595989 (9605-10)
The Dual-Channel Sampler performs time expansion of the I- and
Q-channel baseband signals from the radar receiver in order to
allow further processing and display. It has three switches to
select the system observation range, as well as control knobs for
adjusting the system range origin, the balance of the I- and Q-
channel output signals, and the DC offsets at the I- and Q-
channel outputs. A time base output is provided to obtain an A-
scope display on a conventional oscilloscope.
Unregulated DC power is automatically supplied to the Dual-Channel Sampler through self-aligning connectors
when it is installed on the Power Supply / Antenna Motor Driver

Target Positioning System
8121782 (9607-30)
The Target Positioning System positions a passive radar target accurately. The system consists of a mobile
target table, a remote target controller module connected to the table via a multiway cable, and four types of
targets (a sphere, a cylinder, a 90-degree reflector, three metal plates and a plexiglass plate). The surface of the
target table measures 90 by 90 cm (35.1 x 35.1 in) and is marked with a 1-cm (0.39-in) grid.
The system provides closed-loop DC servo control of the position and speed of the target in X and Y. On the
target controller, either manual control of target position and speed or one of four preprogrammed trajectories
can be selected. Two three-digit displays give a readout of the X and Y position or speed of the target. The target
position can be controlled externally using rear panel inputs.
