Here you can see the result of test measurements. Showing short circuit measurement (black)
1), open circuit measurement using FRAX-101 (green)2) and FTB-101 measurement (red).
1) A simple test to check the integrity of test leads is a short circuit test. Simply connect the
"Source"/"Reference" and "Measure" clip together and connect the respective measurement
earth/ground together. The result should be an almost straight line around 0 dB (black).
2) An open circuit measurement should in theory provide a 0-response, i.e. a minus infinity
dB-response. However, all measurement systems have internal noise and the test leads will
also add some response from open clips ends. Separate the "Source"/"Reference" clip from
the "Measure" clip. The clips itself will give some influence at highest frequencies, if you
disconnect the "Measure" coaxial cable from the FRAX unit you will see the noise in the
measurement system (green)
