Hello,
I have a generator that powers an ultrasonic transducer. The connection type is a BNC Female on the gen and BNC Male on the transducer. I am wondering in how it would be the best way to tap into the signal and measure it with an scope. I found these BNC T adapters that have 2 females and 1 male but I am confused in to what impedance to choose. My scope has a 1 M Ohm input impedance and I am using Isolated differential probes. I do not want to use the BNC T of 50 Ohm (or the 75 Ohm) and mess up either the scope, generator, or transducer. This test needs to be non destructive (as an I cannot peel the cable insulation to tap into the core and shield of the coaxial cable) because I am going to be using it for production after the test.
The Tektronix guy suggested a 75 ohm feedthrough terminator but I am unsure in how to use those or how it would affect my signal.
If any suggestions, I would really appreciate it.
