IZT C6000 for synchronous bi-directional satellite Links built-in Rack with Laptop

Channel Emulators

Since 2006 IZT develops Channel Emulators to simulate the transmission from ground station to the receivers for satellite and terrestrial applications. Initially starting with the IZT DCS3020 for a DVB-S2 and DVB-RCS bi-directional link and 34MHz of bandwidth IZT has enhanced its products to 100MHz of instantaneous bandwidth in the IZT C3040 and even 600MHz in the IZT C6000.

More about IZT Channel Emulators

Features as Doppler effect (delay and frequency changes over time), ionosphere and interference simulation in the uplink, MUX filtering, phase noise simulation and non linearities in the payload or multipath fading and thermal noise generation in the downlink can all be simulated within the equipment.

IZT’s Channel Emulators combine exceptional RF performance with modern digital signal processing. Customers using the equipment have confirmed that measurement results in the laboratory could be reproduced over the transmission link once the satellites had been launched to space.

IZT Satellite Channel Emulators was for example used in the following projects:

  • Adaptive Coding and Modulation Modem for Broadband Communications
  • EGNOS NLES G2 RF Payload Simulator
  • DVB-S2X
  • Earth observation and Broadband communication

The IZT C3080 is a wideband digital channel simulator especially suited for simulating transmissions over satellites. Modern communication systems adapt not only higher frequencies but also wider bandwidths, therefore the IZT C3080 was designed to simulate a bandwidth of up to 680 MHz.

  • 680 MHz of instantenous bandwidth
  • Flatness of less than ±0.5dB
  • Group delay less than ±1ns
  • IMUX / OMUX Filtering
  • Non linearity simulation (AM/AM and AM/PM)
  • Phase noise simulation
  • Thermal noise (AWGN)
