The R&SSML allows the mode of frequency generation to be selected. In the Extended Divider range mode, the RF signal is generated by frequency division. The excellent values obtained in this mode for SSB phase noise are comparable with the high-grade crystal oscillators normally used as reference sources from 10MHz to 30 MHz. Compared to crystal oscillators, theSML provides the following benefits:Frequency can be set in 0.1 Hz stepsand synchronized to an external reference, All functions can be remotely controlled via the IEC/IEEE bus or serial interface
