Производитель: ETL
Страна: Великобритания
L-band Matrix M0404D1UFL-21119-N5N5: 4 Inputs x 4 Outputs Distributive SNG Truck Matrix with dual redundant power supplies and 50 Ω N-type connectors
ETL Model M0404D1UFL-21119, 4 x 4 SNG Truck Receive L-band Matrix with LNB Powering & Local Control Only.
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.
This smaller range of distributive L-band Matrix comes in a variety of size configurations which are generally linked to original design applications. The 2U 8x8 L-band Matrix and 3U 16x16 L-band Matrix are standard building blocks for most applications with dual redundant PSU's, a CPU and local control panel. Remote control is via serial or Ethernet.
More specialist is the 8x24 L-band Router is 4U and optimised for asymmetric dual antenna cruise ship matrices. Likewise the 8x16 (2U) and 4x8 (2U) and 1U SNG truck matrices are designed for specific applications.
While some of the L-band matrix products in this range have hot-swap power supplies, please see our Hot Swap Matrix range for matrices with hot swap of RF modules, CPU's and PSU's.
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.
4 x 4 SNG Truck Receive L-band Matrix With LNB Powering & Local Control Only
This SNG truck matrix, employs the latest ETL switching and routing technology and has been designed to provide economical high performance L-band routing for SNG trucks and other mobile installations.
The compact and lightweight design also favours this use. The human interface is simpler than standard ETL matrices, but still fully effective and helps to optimise costs. There is only local control of the routing.
The matrix can handle 4 inputs and 4 outputs and is fully distributive (any input can be routed to any or all outputs). The 19” 1U high shelf has a single mains power
supply. LNB power (13V DC) is always available at the RF input ports. There is a dry contact alarm port in the event of power supply failure.
This unit has 50 ohm N-type connectors, but other impedances and connector types are available (model numbers will vary).
