Phase-Coherent, Multi-Channel PXIe VSG (Shared LO)
V2802A LO Distribution Network
Unlike the independent LO use case, phase coherency requires the V2802A LO
Distribution Network to be placed between the two chassis. In the 4-channel
configuration, a single LO (M9301A) has four ports that can drive up to four
M9381A or M9391A instruments. For more than five and up to 8-channel
configurations, it is required to have all LO outputs drive from a single device. The
LO Distribution Network enables phase coherency for five to eight VSGs or VSAs by
distributing a single LO to all channels. This gives the multi-channel system a
highly precise and stable alignment between up to eight signal analyzers and eight
signal generators.
