LCX

AT A GLANCE

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.

The R&S®LCX100 LCR meter covers the frequency range from 4 Hz to 300 kHz. The R&S®LCX200 has an upper frequency limit of 500 kHz and can be extended to 1 MHz or 10 MHz using software options when needed. All instruments offer DC measurements as well. Internally generated voltages of up to 10 V cover most applications. Optionally, bias voltages of up to 40 V can be applied externally. A fast logging function records all measured values up to 10 times per second. Dynamic impedance measurements can be performed using the advanced analysis function. In these sweep measurements, the impedance values are determined for a series of frequency values or other parameters.

Measurements can be triggered and controlled externally via digital I/O ports. The binning function enables the measured components to be sorted by their values into up to eight categories. The large capacitive touchscreen is the central element for modern and intuitive operation of the instruments and enables the graphical display of the measurement results. Remote controllability and rack installation predestine the R&S®LCX for system applications.
