ı The two path SMW + SGS/SGU allows to generate 4 RF paths per set
ı Sets can be cascaded by LO distribution across instruments, which creates coherent and phase stable RF
ı Phase relations are set via baseband of SMW
ı SMW + SGSı SMW + SGS + SGU ı Complete setup is controlled from the
GUI of the SMW LO distribution
