Default Using Tuner to Determine Line Input Impedance
From: dykesc
Date: Wed, 3 Jun 2009 Time: 10:57:52

I am trying to validate impedance values I am measuring with my
MFJ-259B. I want to do this by using my MFJ-993B auto tuner. The tuner
uses a simple L network to create the conjugate match. I want to take
the final inductance, capacitance and swr values from the auto tuner
digital display after matching is completed and back calculate the
impedance that the tuner is seeing. Is there an online calculator that
will do this?

Many thanks for replys.


Is this any help?
