Since the 1 GHz reference is available as standard, it is a cost-efficient alternative for selected applications that require phase-coherent signals. Particularly at lower RF frequencies since the phase stability performance improves with lower RF outputs. The resulting phase stability at 500 MHz, for example, is excellent

Reference coupling is also required for phase-coherent systems with different RF output frequencies since LO coupled systems only support identical RF frequencies. The 1 GHz reference of the R&S^{®}SGT100A makes it possible to achieve excellent phase stability for such applications where phase-coherence with different RF frequencies is required.

The R&S^{®}SGT100A is a compact and cost-efficient solution for phase-coherent systems up to 6 GHz..
