The DT230 is a professional test equipment for the DRM system. It can play back complex baseband DRM signals and record RF bandpass signals by using a direct sampling A/D and D/A solution for the frequency range from 100 kHz up to 27.4 MHz.
The optional channel simulator module O1 models all relevant properties of the short wave ionospheric propagation channel according to the stationary Watterson model approach. The dynamic profile option O2 makes it possible to change all simulator parameters dynamically. For the automatic evaluation of receiver performance option O3 is available.
The real-time modulation option O4 allows for the RF modulation of MDI (Multiplex Distribution Interface) data either from the Ethernet or pre-generated MDI files played back from the internal hard disk.
