Calibrating the Bode 100
7.6 Calibration in the Frequency Sweep
(External Coupler) Mode
By calibrating the Bode 100 in the Frequency Sweep (External Coupler)
mode you remove the effects of the connection setup including the external
coupler and, if used, the amplifier on the accuracy of the measurement results.
Due to the strongly varying parameters of directional couplers a calibration is
mandatory before performing a measurement.
In the Frequency Sweep (External Coupler) mode, you can perform only
Impedance/Reflection measurements. Therefore only the Impedance
calibration is available in this mode.
Hint: Some directional couplers show nonlinear behavior at the edges of their
passband. If your measurement frequency range is close to such nonlinearities,
we recommend to use the User Calibration to remove the nonlinear effects.
To calibrate the Bode 100 in the Frequency Sweep (External Coupler) mode:
1. Click the Frequency Sweep (External Coupler) toolbar button to switch
to the Frequency Sweep (External Coupler) mode.
2. Click the User Calibration toolbar button to open the
calibration window.
