The top-class in component testing

The R&S®LCX LCR meters are versatile, extremely accurate and perform measurements quickly. They are ideal for challenging applications in research, development and production. Two instrument models and various options cover applications with a test signal frequency of up to 10 MHz. Internal and external bias functions, comprehensive analysis options and versatile test fixtures expand the wide range of possible applications.

Features & benefits

Fast, accurate and versatile

Both R&S®LCX models combine high measurement speed, accuracy and versatile measurement capabilities. This makes them ideal for standard measurements in development, for material analysis in research as well as for fast production testing. With their broad measurement ranges, they also cover applications with extremely low and extremely high impedances. Three measurement times are available:

Fast: ≤ 15 ms
Medium: ≤ 100 ms
Slow: ≤ 500 ms

The basic accuracy for impedance measurements is ±0.05 %, and for phase measurements ±0.03°.

Selectable frequency range

All R&S®LCX models measure under DC conditions. The AC range already begins at 4 Hz. The upper frequency limit on the R&S®LCX100 is 300 kHz. In its base configuration, the R&S®LCX200 is designed for a maximum frequency of 500 kHz; this frequency limit can, however, be extended to 1 MHz or 10 MHz. This means that the ideal instrument is available for any given application and budget.

Test signals for all requirements

Test signals can be generated from 100 mV to 10 V and deliver a current of up to 200 mA. The instruments have a selectable output impedance of 100 Ω or 10 Ω. The actual current flow and the voltage applied are measured using the monitor function.

DC bias

In many applications, an adjustable DC bias is needed to measure C and L components at different operating points. The R&S®LCX100 and R&S®LCX200 generate a DC bias voltage of up to 10 V. As an option, it is also possible to set a DC bias current (up to 200 mA). DC bias voltages of up to 40 V can be applied at an external connection on the rear panel (R&S®LCX-K108 option) using a standard DC power supply, for example an R&S®NGA.

Data logging function

The R&S®LCX LCR meters provide a fast logging function for recording all measured values. The data can be saved on an external USB flash drive or transferred to an external PC via USB or LAN. With a data rate of up to 10 sample/s, the measured values are available every 100 ms.

Educational note: Understanding transformer testing

Transformers are passive devices that are primarily used to convert or "transform" alternating current (AC) from one voltage level to another. One very common application of transformers is in AC to DC power supplies, in which mains voltage is stepped down before being rectified and filtered to produce DC. There are numerous other applications for transformers, such as providing electrical isolation or for impedance matching.

Read this educational note and dive into the discussion about the six most important transformer measurements: turns ratio, mutual inductance, phase angle, primary and secondary inductance, leakage inductance, and interwinding capacitance.
