1 Scope

This calibration specification is applicable to the frequency range from 1MHz to 3.0GHz. The basic working principle is the RF voltage-current ratio. Calibration of various types of high frequency and RF impedance/material analyzers for impedance, also applicable to LCR meters of the same principle calibration.

4 Overview

High frequency and RF impedance/material analyzers can be used in inductors and capacitors from 1MHz to 3.0GHz High-frequency measurement and electrical performance evaluation of devices and resistors. This type of instrument uses the principle of RF current-voltage impedance measurement. This method is derived from the high-frequency current-voltage method, and the current flowing through the device under test is converted into electricity by the unbalanced-balanced converter. Pressure, therefore, two vector voltmeters Vi and VV are used in the system (VV detects the vector voltage applied to the device under test, Vi The vector current flowing through the device under test is detected). If the measurement circuit is ideal (this means no stray admittance and residual Impedance), the impedance of the device under test can be expressed as. x=RV Figure 1 IV measurement simplified circuit
