The on-line help Rev A.13.70 (M980xA/P500xA) Rev A.13.10 (P937xA) Rev A.12.60.xx (M9485A/M937xA) - 2-Jul-2019 states that the M980xA doesn't support the multi-site function. Is this because the M980xA is new and the "firmware" hasn't been updated yet for the support or is there some other reason?
PXIe VNA Multisite
Note: M980xA does not support this function.
Yes. It has to do with software licensing. The licenses for other PXI modules were tied to the module. But we recently introduced the idea of transferable licenses (for example you can move time domain from one instrument to another). Licenses are then tied to something like a MAC address rather than the module. But for multisite there is only one MAC address on the controller, so it can't support multisite software licenses. The solution is to have "counted" licenses where we support more than 1 license on a single MAC address. When that enhancement is finished the multisite can be supported.
