this option enables the r&s®smu200a to generate signals in accordance with the xm-radio standard. per baseband generator (option r&s®smu-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:
