8.3.3 Reflection with external coupler
The External coupler measurement mode is designed to measure reflection using an external coupler.
This offers the possibility to use an external amplifier and protect the inputs of Bode 100 by using an
external directional coupler.
Calibration
Please note that the external coupler measurement mode requires an impedance calibration (Open,
Short, Load). For more details on how to perform an impedance calibration see 10.3.2 Calibrating an
External Coupler or External Bridge measurement on page 96.
Typical applications
Typical applications for the external coupler measurement mode are:
• Measuring medium-wave antennas.
• Measuring impedance with high-power amplifiers.
Measurement example
