The ARB enables the IZT C3040 to emulate other traffic on a satellite transponder, signals in adjacent bands or interference scenarios. With the internal ARB memory, the IZT C3040 now supports the generation of user-defined signals, for example using MATLAB, which increases its flexibility.
Maximum sample rate of the ARB is 160 Msamples/sec, which corresponds to a maximum signal bandwidth of 100 MHz. A user-configurable variable sample rate converter allows the use of lower sample rates. The frequency offset and power of the ARB signal can be varied through software while the emulation is running.
The IZT C3040 is a wideband digital channel simulator for satellite or unmanned armed vehicle (UAV) data links. It enables system engineers to create realistic scenarios for testing their product in a laboratory environment, without having the satellite itself available. The company says this extends the IZT C3040 channel simulator's ability to support even more complex test cases, and users can now test a wider range of scenarios.
The new ARB feature is released with Mainbuild MB25 and can be downloaded from IZT's FTP site. Customers interested in the ARB option should contact IZT before installing the new version, to ensure availability of installation support.
The IZT C3040 provides accurate, complex and reproducible simulation of uplink, payload and downlink effects on the signal such as delay and delay change over time, Doppler shift, interference by other signals, multiplexer filtering, phase noise, large and small scale fading, and thermal noise.
An instantaneous bandwidth of 100 MHz is supported for high bandwidth applications, with input and output frequencies between 40 MHz and 3 GHz. Users can create realistic complex and reproducible scenarios to test flight and ground systems such as LEO, GEO, and MEO satellites, UAVs, modems, transmitters and receivers as well as telemetry tracking and ranging verification.
