In most cases, an LCR meter is used for measuring impedance values. However, depending on the type of component, these values vary to a greater or lesser degree at different frequencies and levels.

The R&S LCX-K106 option, which is activated using a keycode (to be ordered separately), can be used for dynamic impedance measurements. In these sweep measurements, the impedance values are determined for a series of frequency values. The voltage or current values of the test signals or of the bias signal can also be used as sweep parameters. The results are shown in tables and graphically.
