Rohde & Schwarz LCX200 – LCR Meter – 500 kHz

• Test signal frequency: DC, 4 Hz to 500 kHz
• Test signal voltage: <1 MHz: 100 mV to 10V; > 1 MHz: 100 mV to 2 V
• DC bias voltage (internal): 0 V to +10 V
• DC bias current (internal): 0 mA to 200 mA
• Source impedance: 100 Ω, 10 Ω

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.

LCX Series 

Both R&S LCX models combine high measurement speed, accuracy and versatile measurement capabilities. This makes them the ideal instruments 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°.

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.

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.

In many applications, an adjustable DC bias is necessary in order 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.

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.

In addition to the many different impedance measurements, the two R&S®LCX LCR meters are also able to measure transformers as well as resistances with DC voltage. The display can show up to four measurement parameters at the same time, and the measurement functions can be selected in pairs.
