SDA-5500 Stealth Sweep Transceiver
The SDA-5500 is a standard 19" rack mount unit weighing approximately
fifteen pounds. Its 320 X 240 dot matrix LCD shows measurement data in
both graphical and numerical form. It is a full-featured signal analysis meter
with a complete spectrum display and an analog representation of single
channel measurement data. When tuned to a specific channel, a
comprehensive set of information is provided, including:
• tuned channel
• video frequency and level
• audio frequency and level
• differences between video and audio carrier levels
The SDA-5500 performs essential cable TV system preventive maintenance
tests with accuracy and ease. Signal levels, hum, C/N, and, in tandem with
the SDA-5000, frequency response, can be quickly tested without interfering
with subscribers’ service.
The Sweep System is made up of two components: the field unit (SDA-
5000), and one or both of the headend units (SDA-5500 and SDA-5510).
Sweep response is tested by injecting a low-level signal in vacant spectrum
areas and by monitoring cable system carrier levels in occupied spectrum
