Impedance measurement parameters of the R&S

LCX

In addition to the characterization of the resistance, inductance and capacity of passive
components, the R&S

LCX determines parameters like the quality factor (Q), the dissi-

pation factor (D), the phase angle (

), and the complex values of the impedance (Z)

and the admittance (Y).

The following tables show the parameter pairs that you can select for display.
