Weatherized Outdoor X-Band Satellite Loop Test Translator
Offers Remote-Controllable Attenuation and Monitoring
– Rugged Outdoor Testing Unit Also Available in Ku and C Band Versions –
Tampa, Florida (October 17, 2005) --- Tampa Microwave announced the
availability of the weatherized X Band Loop Test Translator, a new field test tool
especially well suited for military satellite communication applications.
This rugged outdoor testing unit is remote-controllable via RS 485, and enables
X band transmit-to-receive, frequency translations. As with all Tampa Microwave
LTTs, the weatherized outdoor X Band Loop Test Translator delivers reliable
translations with a minimum of amplitude and delay distortions. The unit is
housed in a rugged, weather-resistant case, which allows mounting in an
antenna hub or in an outdoor environment.
This unit is also available in Ku and C Band versions that deliver the same
features and performance specifications.
Tampa Microwave loop test translators are designed to allow a satellite to be
“short circuited” so that terminal output can be fed to downlink monitoring
equipment. Functional specifications are as follows:
