Test Loop Translators

ETL Systems

Comprehensive testing capabilities for various applications and environmental conditions.

GENUS Test Loop Translators

Versatile solutions to suit various operational environments.

Test Loop Translators are engineered to replace satellite links for testing and aligning earth station systems across S, C, Ku, K, Ka, and Q frequency bands. These devices utilise fundamental frequency phase-locked oscillators and double-balanced mixers to block convert frequencies from uplink to downlink, enabling instantaneous monitoring of frequency, power levels, and modulation. 

ETL’s Test Loop Translators (TLT) are versatile solutions available in several formats to suit various operational environments. For those needing integration into a standard setup, our TLTs are available in the GENUS rack system, providing seamless integration with other equipment in a robust and scalable chassis.  

For more flexible and mobile applications, the benchtop model offers ease of use and portability, ideal for laboratory and field testing. Additionally, our  ruggedised TLTs are designed to withstand harsh environmental conditions, ensuring reliable performance in challenging outdoor or industrial settings. This variety ensures that ETL’s TLTs meet the needs of diverse testing requirements, from controlled environments to demanding field conditions. 

  • Covers S, C, Ku, K, Ka, and Q frequency ranges  
  • Options for manual control, Ethernet control, battery operation, portable and ruggedised designed, dual-channel configurations, and reversible signal paths. 
  • Crucial benefits such as real-time performance monitoring and accurate frequency conversion.

GENUS Ecosystem

GENUS modular system

The latest advancement in chassis technology, offering a compact, modular, and flexible solution for growing teleport operators. Available in 1U, 2U, and 3U rack sizes, and in outdoor unit (ODU) versions, the GENUS chassis can accommodate up to 17 RF distribution modules, allowing operators to customise their setup according to their specific needs.

This modularity provides a high degree of adaptability, making the GENUS smart chassis an ideal choice for operators looking to scale their operations efficiently and effectively. The smart chassis concept allows for the housing of multiple RF modules within the same shelf, providing space savings, reduced costs, and increased rack space efficiency.

Modular, configurable chassis

The GENUS chassis integrates StingRay RF over fibre, Falcon frequency converters, Alto amplifiers, digitisers, switches, splitters, 10 MHz injection, and small RF matrices/routers, all within a single indoor or outdoor chassis.

Flexibility

Operators can configure the GENUS chassis to meet their exact RF distribution needs, ensuring optimal performance and efficiency.

Cost reduction

By providing space savings and offering hot-swappable components, the GENUS range reduces running costs and enhances maintenance efficiency.

Unified protocol and commands

Consistent protocol and software commands across multiple chassis types, with standardised webpage across all platforms for ease of use. Additionally, uses the same power supply units (PSUs) and central processing units (CPUs) across different chassis types for commonality of spares.
