The channel simulator IZT C3040 is the successor of the IZT DCS3020. It 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.

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
