Features

  • Used to determine antenna resonant frequency
  • Whetstone bridge design
  • 2-Channel Scope BNC connections
  • Signal Generator BNC input
  • Antenna Under Test BNC connection
  • Form factor matches standard 50mmx80mm extruded enclosure

Measuring Complex Impedances

  • This circuit can be used to measure complex impedance
  • R2 and R5 are not critical but should be matched
  • R1 and R3 should probably be 50-ish Ohms (47 Ohm should be OK)
  • R4 should probably be somewhere near the nominal resistance of the load you are testing
  • Scope may need to be floated depending upon the network that is being measured
