The R&S®FSW-K70M multicarrier modulation analysis application (R&S®FSW-K70 option required) allows DVB‑S2X signals to be analyzed. The R&S®FSW-K70M detects the start of frame, demodulates both the header and payload parts of the signal and displays the constellation diagram and relevant modulation analysis parameters. The R&S®FSW-K70P is an extension of the R&S®FSW-K70 vector signal analysis option that allows the measurement of raw bit error rate (BER) on PRBS data up to PRBS23. In addition, the R&S®FSW-K70 offers the ability to measure BER based on user-defined bit sequences.
