NiGMa Matrix Router (IF & L-band) 32x32 NGM-25-B7B7
Производитель: ETL
Страна: Великобритания
IF & L-band Matrix 32x32 NGM-25-B7B7: 32 Inputs x 32 Outputs Distributive Hot-swap NiGMa Series with dual redundant power supplies and 75 Ω BNC connectors
32 Inputs x 32 Outputs Distributive Hot-swap NiGMa L-band and IF Matrix.
The NiGMa L-band and IF Matrix is housed in a 6U 19" rack enclosure. It has a module capacity of 32 inputs x 32 outputs, but can be part populated to any size, such as those shown below. It can then be hot expanded up to 32 x 32. The NiGMa IF and L-band Router can easily be formed into larger Matrix Systems up to 512x512 by adding additional modules.
A variety of impedances and connector types are available, as shown below.
Now in its 3rd generation, the NiGMa L-band and IF Matrix has proved to be genuinely high performance with excellent flatness or frequency response, excellent isolation, and linearity - a truly leading edge L-band and IF Router.
The NiGMaL-band and IF Matrix has hot swap of all active components - RF cards, CPU's and PSU's. In addition the NiGMa L-band and IF Matrix has the designed-in resilience provided by one RF card for each RF input and output, dual redundant CPU's, and dual redundant PSU's.
The NiGMa L-band and IF Matrix also has extensive on-board monitoring - and reporting - of RF card amplifier status, CPU and PSU status and HMI communications.
The professional solution for IF and L-band signal routing
ETL’s high performance NiGMa matrix has evolved to handle IF and L-band distributive signals. This matrix router sets new benchmarks for RF performance and leading edge technologies. The next generation of NiGMa matrix focuses on improved resilience and performance the impact of failure is minimised throughout the unit.
As ETL customers use matrices in mission-critical applications, we understand the importance of redundancy and hot swap. Input and output cards, power supplies, CPU controller cards, fans and the new VGA human interface can all be hot swapped. New Matrix design means there is one card associated with each input and each output – so failure of a card only affects one channel. For broadcasters, satellite operators and the defence sector, this provides exceptional resilience. The refined design offers rugged dual redundant power supplies with simple front access, enhanced CPU change-out, hot-swap fans and new card connectors. Web Browser Interface is standard on an NGM-25.
Improved RF performance of the NiGMa which provides superior Isolation, frequency response or flatness, and 1 dB GCP levels – helping our customers ensure that their o v e r a l l R F c h a i n s i g n a l p e r f o r m a n c e i s o p t i m i s e d .
Self Diagnostics with continuous monitoring (and reporting) of amplifier status, PSU status (including temperature), fan speed and internal communications is included as standard. Any problems are rapidly identified and hot swap means they can be addressed in minutes.
