I am working on a measurement system for voltage harmonic signals in the range from 100Hz-10kHz . i am using the PXI-5922 digitizer for measurements. I need to use a coaxial cable with a length of 20m to transmit the signal from the voltage transducer to the digitizer. As i am new to this subject, it would be great if anyone can suggest me on impedance matching of the cable to minimize the measurement error on voltage amplitude and phase.
