and Radar 2. Trigger pulses from both radar sets are
amplified and shaped in this equipment; video
information from either (but not both) radar set is only
amplified. Antenna bearing information from either (but
not both) radar set is directly routed to the output lines.
An oscilloscope is included as part of this equipment to
monitor all input and out-put signals.
RELATION TO SIMILAR EQUIPMENT
