It should be possible to use the FLEX-5000 for impedance measurement since it is full duplex capable. It is not possible to do this with the SDR-1000 because of its half duplex architecture. On the 5000, we should be able to use the XVTX as the signal source (~0 dBm max) and XVRX as the detector. All that is needed is a directional coupler and the software to do the analysis. Effectively it would be a two port vector network analyzer (VNA). This is something we would like to do as time permits.
