I'd like to bounce this off some experts......

I'm looking for a Vector Impedance Meter. I have a Vector
Voltmeter (no manual on it). I take it the Vector Voltmeter
basically indicates phase shift between two AC voltages.

Using a signal generator as a source, can I connect a small 
series "non inductive" resistor with the unknown impedance, 
measure that as current, compare the input voltage phase to 
the output current phase to get the Z phase (reactance). Then 
calculate the Resistance part of Z by using the input voltage 
and output current ?
