The IZT C3040 from IZT is a Satellite Link Emulator that operates from 40 MHz-3 GHz. It has an attenuation of 70 dB and a bandwidth of 100-108 MHz. This cost-effective satellite link emulator has an input power of 20 dBm and an output power of 15 dBm. It requires an AC voltage of 100-240 V, has a Doppler shift range of -1.25-1.25 MHz, and a Doppler Shift Resolution of 1 Hz. It has a power consumption of 200 W and it has a mass of about 12 kg. The IZT C3040 uses high-quality hardware and highly optimized DSP code to simulate the effects which uplink, payload, and downlink have on the signal. These effects include delay and delay variation over time, impairments caused by the MUX filters of the satellite, and effects on the ionosphere and the propagation through the atmosphere. This EN-55022, class-B compliant emulator has a spectrum display with automatic C/N control and is ideal for applications such as satellite (LEO, GEO, MEO), UAV, modem, transmitter, and receiver testing, telemetry tracking system and range verification and training.
