It is unfortunate that SI engineers do not begin with the basics in RF - go get
a ham license, become comfortable building RF equipment!
Grab a copy of ARRL, QST, etc. and read up, there are lots of TDR ideas on the
cheap, and you will actually learn something by building it, and sitting on the
bench. Heres one:

If you care about the result, buy a network analyzer. They are NOT expensive
and have many uses beyond Impedance. If you want to be an engineer you need
to have the basic tool and a VNA is even more valuable than a scope in some
cases.
That or hire someone to do the measurement for you.

Subject: [SI-LIST] Impedance measurement
I am looking to measure impedance of a trace on a PCB. What is the simplest
way to do. I neither have TDR nor the network analyzer. I am looking for a
crude method of measuring it. Please, suggest ways of doing it.
