Bode 100 User Manual

In the Frequency Sweep (External Coupler) mode you can perform a
sequence of Impedance/Reflection measurements by using an external
directional coupler only or in combination with an external amplifier.
For some impedance measurement applications, it is beneficial to use external
couplers for an optimum adaptation of the Bode 100 to the test object (see
Figure 6-2: "Connecting external coupler" below). Further on, impedance
measurements on some test objects such as medium wave antenna systems
require higher signal levels than provided by the Bode 100. By using an external
coupler it is possible to utilize an external amplifier to boost the Bode 100 source
signal to the required output level (see Figure 6-3: "Connecting external coupler
and amplifier" below).
