Description

Hollis Electronics HTSS is a quad diversity Troposcatter channel simulator which interfaces with your radio equipment at 70 MHz IF. The complete digital implementation provides high accuracy and exact repeatability. An integrated AWGN noise source coupled with an internal power meter supports accurate setting of SNR and Eb/No.
The HTSS uses the latest in Digital Signal Processing (DSP) technologies for a flexible, cost effective platform for radio channel simulation of Troposcatter communications.
