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
