LCR Meters and Impedance Analyzers Catalog

The Keysight LCR Meters and Impedance Analyzers Catalog provides a comprehensive overview of precision instruments designed for component testing, circuit evaluation, and materials characterization across a wide frequency range. Organized into benchtop LCR meters, handheld LCR meters, and impedance analyzers, the catalog covers three capability classes that span maximum frequencies from 1 kHz to 3 GHz. It includes benchtop instruments for high accuracy component characterization, portable LCR meters for quick checks and troubleshooting in the field, and advanced impedance analyzers for high frequency, complex material and device evaluation. These instruments support applications across power electronics, RF design, component manufacturing, materials research, quality assurance, and production testing.
 

Explore the LCR and impedance analyzer performance classes:

• Benchtop LCR meters come in the ZA2-class, which includes the E4980B Series, and support maximum frequencies from 1 MHz to 3 GHz and target general purpose devices, materials, and capacitors. These benchtop LCR meters deliver highly precise resistance, capacitance, inductance, and impedance measurements with basic accuracy as low as 0.05 percent. The ZA2-class offers robust error compensation methods, flexible test signal settings for voltage and current, and multiple interfaces including LAN, USB, and GPIB for automated test integration. Their precision and repeatability make them suitable for component characterization under varied frequencies, signal levels, and bias conditions.
  
  
• Handheld capacitance and LCR meters come in the ZA1-class which includes the U1700 Series. They operate from 1 kHz to 100 kHz and support capacitance measurements from 20 pF to 199.99 mF. These portable meters automatically identify passive components, feature a backlit dual display, and provide up to 16 hours of battery life for extended field or production use. Their compact and ergonomic design supports one‑handed measurements in tight spaces and offers fast, reliable evaluation of inductance, capacitance, and resistance. ZA1 meters bring bench‑level accuracy to field environments and general troubleshooting workflows.
• Impedance analyzers come in the ZA5-class which includes the E4990A Series. They support maximum frequencies from 120 MHz to 3 GHz and target general purpose devices and materials. These analyzers extend beyond basic LCR measurement to advanced analysis such as equivalent circuit modeling, high frequency characterization, and materials validation. They feature integrated DC bias sources up to ±40 V and ±100 mA, built in permittivity and permeability measurement capabilities, enhanced data analysis tools, and a large 10.4-inch color touchscreen with multitrace views, marker functions, and limit line testing. The ZA5-class is ideal for evaluating complex materials, performing high frequency impedance analysis, and extracting model parameters for demanding engineering applications.
   

Benchtop, handheld, and analyzer architectures provide flexible solutions across applications. 
Benchtop LCR meters support high precision component characterization in controlled lab environments. Handheld LCR meters offer mobility for field service, production floor diagnostics, and quick checking of passive components. Impedance analyzers deliver advanced analysis for materials testing, RF device characterization, and research‑level component evaluation. Each platform is optimized for its workflow, offering frequency range, test configuration, and measurement depth tailored to the engineering need.
 

Software and accessories extend measurement capability across all instrument classes. 
Keysight software solutions support remote control, enhanced visualization, data logging, and material measurement analysis for benchtop LCR meters and impedance analyzers. Available software includes instrument control applications, LCR meter control tools, and material measurement suites that support permittivity, permeability, and loss of tangent characterization. Accessories include power adapters, calibration kits, probes, adapters, test fixtures, and cables to ensure accurate, reliable connections and optimized measurement performance. These options allow engineers to adapt instruments for passive component evaluation, material analysis, automated test systems, and quality assurance of workflows.
