Satelitte Test Loop Translator ATLT-400 model
Overview
The Advantech Test Loop Translators ATLT-400 models are available in variety of operating bands. The units are designed for testing satellite communications links. They simulate the satellite by band-translating the uplink frequencies to the corresponding downlink frequency. A single quad band TLT unit works with four operating frequency bands – C, X, Ku and Ka.
Features
- Four Operating Bands – C, X, Ku, and Ka
- Cost effective solution
- Front panel control (local)
- Full remote control (remote)
Options
- 5 MHz external reference
- Other operating bands
