NiGMa L-band Matrix Router 32x32 NGM-21-B7B7

Производитель: ETL
Страна: Великобритания

32 Inputs x 32 Outputs Distributive Hot-swap NiGMa L-band Matrix.

ETL has a broad L-band Switch Matrix and L-band Router range for Satellite communications, including the hot-swap NiGMa L-band Matrix which is used for many high resilience high performance applications.

The NiGMa L-band 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 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 Matrix has proved to be genuinely high performance with excellent flatness or frequency response, excellent isolation, and linearity - a truly leading edge L-band Router.

The NiGMa L-band matrix has hot swap of all active components - RF cards, CPU's and PSU's. In addition the NiGMa L-band 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 Matrix also has extensive on-board monitoring - and reporting - of RF card amplifier status, CPU and PSU status and HMI communications.

Non-blocking: this means any input can be routed to any output.

In general our solid state (L-band) matrices are non-blocking.

Full Fan-out Matrix (or fully distributive or splitting matrix): any input can be routed to any output. One input can be routed to many outputs. Each output can only have one input. Tends to be more RX.


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-21.
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.
-Fast Matrix Card Changeout from front and rear
-On board log records all routing changes for each user
-Touchscreen VGA control with security log on for up to 10 users
-Aliases (10 character) on front screen to identify signal sources
The Enigma Matrix can be adapted and grown to a number of different sizes
Resilience is designed-in
-The NiGMa matrix has been designed with resilience in mind. The impact of component failure is minimised and all active components can be hot swapped. Problems are rapidly identified and can be easily sorted out.
-Minimal impact from card failure
One card per input and one card per output mean that the impact of card failure is minimised. Cards can be hot-swapped, and hot expansion can take place in single increments.
-Minimal impact from CPU failure
The matrix contains dual redundant CPU’s which both operate in parallel. If one CPU fails the other automatically becomes the master. CPU’s can be hot-swapped.
-Minimal impact from PSU failure
Dual redundant PSU’s can be hot-swapped.
-Rapid diagnosis of problems
The matrix continuously monitors the conditions of amplifiers, CPUs and PSUs. Any faults are immediately reported through the front panel and remotely. Alarms report the specific faults down to component level.
