Rohde & Schwarz launches its new LCR meter family of high performance general purpose impedance testers covering a wide range of applications. With its supported frequency range from 4 Hz to 10 MHz, the R&S 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 R&S LCX models provide high precision impedance values with market-leading accuracy. Equally, higher speed measurements at production-use accuracy for quality control and monitoring are also supported. All the essential 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 R&S LCX 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 R&S LCX covers many applications, such as the measurement of equivalent series resistance (ESR) and equivalent series inductance (ESL) of electrolytic capacitors and DC-link capacitors. Furthermore, users can test transformers and measure DC resistance in addition to the full range of impedance measurements. To investigate components with impedance values varying at different frequencies and levels, option R&S LCX-K106 supports dynamic impedance measurements with the frequency, voltage or current as the swept parameter.
