The HP4805a isn't an impedance meter. It's a vector voltmeter, which
measures voltage amplitude and phase. . .


I think the OP really means 8405 which is a VVM. I think he swapped the
first two numbers.

He can tell us if I'm wrong.


Can't speak for the OP, but I definitely meant HP8405a, the vector
voltmeter. I apologize for the transposition, and also to the OP if I
made the wrong assumption about what instrument he meant.
