Even when SourceMeter is used for AC impedance, two are required. One to apply the voltage sine wave; and one to measure the current in time sync.
This can give you the Z and phase shift.
Even so, the freq of the resulting sine waves that you can generate with a SourceMeter will be a few hundred Hz in best case.
Some SourceMeter models, 2600B in particular, has dual A/D converters, so can in theory get by with one meter and do both I and V. But sine wave freq will still fall short of your 10MHz freq.
You need an LCR meter or the 4210-CVU.
