29.10.2018. Dual modular switch company ETL Systems

Currently, broadcasting and other companies operate in a highly competitive environment where they have to deliver the right information to consumers anywhere and at any time. Often, broadcasters have to work with various technical platforms. In this regard, technical solutions that provide hardware-based accuracy and enhanced functionality become relevant. The new dual modular switch of the Griffin series company ETL Systems - GRF-C900-1U is intended for such situations.
The new product is a 1U chassis unit with two slots in which separate modular switches are installed. Several types of switches can be installed in a common package, intended for radio channels and data channels in the ASI format, through which video streams are transmitted. Individual modules in a common unit can be switched independently of each other or together. Channel switching can be performed from the front panel, when a radio signal is detected, by an alarm signal, and in another way.
Three models for radio channels and one model for digital ASI channels with two inputs and one output each can be used as separate switches.
General characteristics of the unit with switches:

  • dimensions: height 1U (44.45 mm) x depth 285 mm x width 19 inches (482.6 mm);
  • total weight: 3 kg;
  • operating temperature range: 0 - 45 °С;
  • power supply: 85 - 264 V, 50/60 Hz.
The main characteristics of the models of individual switches for radio signals:
  • total frequency band: DC - 2450 MHz;
  • isolation: 60 dB;
  • maximum insertion loss of 2 dB;
  • noise ratio 2 dB;
  • return input / output loss: 16 dB (for most operating frequencies and connectors);
  • input signal detection interval: 0 ... -50 dBm.
Switches on RF ports use SMA, BNC, F and N-type connectors. The switching modules are remotely controlled using Ethernet RJ45, RS232 / 485 interfaces and others.

Typical applications for the new device are satellite modulators, low-noise blocks / down-converters, modems.
