Channel Simulators

Channel Simulators

Channel simulators combine receiver and signal source technology to create powerful radio-channel simulators, which can quickly and dynamically change parameters such as delay, fading, phase noise and filter effects.

The IZT C3040 offers a higher instantaneous bandwidth of 100 MHz, more flexibility in terms of RF modules and an enhanced feature set. The available features were grouped into uplink, payload and downlink effects. Some features are available twice to reproduce a realistic transmission chain.


  • Input and output frequency up to 3 GHz
  • Instantaneous bandwidth of 100 MHz
  • Simulation of uplink, payload and downlink
  • Synchronization of multiple IZT C3040 possible
Key features

Effects of the uplink include:

  • Delay and delay change over time
  • Doppler simulation
  • Effects of the ionosphere
  • Interference by other signals.

Within the payload of the satellite the following effects are introduced:

  • IMUX filtering
  • Nonlinearity (AM/AM and AM/PM) caused by the amplifier
  • Phase noise
  • OMUX filtering.

On the downlink, from the satellite to the terminal the signal then changes by:

  • Effects of the ionosphere
  • Large and small scale fading
  • Interference by other signals
  • Thermal noise.
