Rohde & Schwarz LCX frequency range impedance meters

Wednesday, 23 March, 2022 | Supplied by: Rohde & Schwarz (Australia) Pty Ltd

With its supported frequency range from 4 to 10 MHz, the LCX is suitable not only for the vast majority of devices operating at conventional 50 or 60 Hz domestic power frequencies or 400 Hz for aircraft, but also for everything from low-frequency seismic sensors to high-power communication circuits operating at several megahertz.

For engineers selecting suitable capacitors, inductances, resistors and analog filters to match the device application, the meters are designed to provide precision impedance values with accuracy. Higher speed measurements at production-use accuracy for quality control and monitoring are also supported. All the software and hardware required for production environments is available, including remote control and result logging, as well as rack mounting for the instrument and a full range of test fixtures for handling components.

The auto-balancing bridge technology used by the meters supports conventional impedance measurements by measuring the AC voltage and current for the device under test, including the phase shift. This is then used to calculate complex impedance at any given operational point.

As a general-purpose LCR meter, the LCX covers many applications, such as the measurement of equivalent series resistance and equivalent series inductance of electrolytic capacitors and DC-link capacitors. Users can test transformers and measure DC resistance in addition to the full range of impedance measurements.

The range includes two models: the LCX100 covers a frequency range from 4 Hz to 300 kHz, the LCX200 a basic frequency range from 4 Hz to 500 kHz with options to cover all frequencies up to 10 MHz. Both models feature a large capacitive touchscreen and virtual keyboard to support tap-and-test for all main measurements.

Alternatively, voltage, current and frequency values can be set using the rotary knob. Less frequently used functions are menu-operated. Settings, results and statistics can be displayed on the screen or output for automated post-processing. Up to four measurements can be selected and plotted versus time, with minimum and maximum values included in the display for at-a-glance pass/fail analysis.
