Key Facts This option enables the R&S®SMJ100A to generate signals in accordance with the XM-Radio standard. Per baseband generator (option R&S®SMJ-B9/B10/B11), one satellite signal or one terrestrial signal of up to 20 min duration can be generated. The XM-Radio signal consists of ensemble A and ensemble B. Within an ensemble, the XM-Radio signal is transmitted via two satellites (QPSK-modulation) and additionally via one terrestrial repeater (COFDM-modulation). The following table shows the carrier frequencies for the corresponding channels:
