3-Port Impedance
3-Port Impedance (V/I Method)
Measure output impedance on higher-voltage rails (12 V and up) using the 3-port V/I method — injecting a current while measuring the voltage response — where a 2-port shunt would risk your instrument.
Works with any VNA or Oscilloscope. Buy the parts you need below, or request a quote for the full setup.
