DEV 19128 SIGMA ARCHIMEDES L-Band Matrix Switch, up to 128x128

DEV 19128 SIGMA ARCHIMEDES L-Band Matrix Switch, up to 128x128 

The DEV 19128 SIGMA ARCHIMEDES L-Band Matrix Switch provides scalable routing for up to 128 inputs and 128 outputs within a compact 19-inch, 10 RU chassis. Designed for teleports, satellite ground stations, broadcasters and mission-critical RF networks, SIGMA combines high-density signal routing with modular expansion, hot-swappable components and advanced redundancy.

Input and output capacity can be configured in increments of eight channels and upgraded in the field. Multiple DEV 19128 chassis can be clustered into a unified matrix with configurations up to 512x512 without external splitter or combiner hardware.

SIGMA supports 50 Ohm, 75 Ohm and optical inputs, along with 50 Ohm and 75 Ohm RF outputs. Available features include adjustable gain, variable slope, RF sensing, LNB power, input-channel redundancy, redundant controllers, an integrated spectrum analyzer and a 15.1-inch multi-touch display. The DEV Web Interface and SNMP provide comprehensive local and remote management.
