Keysight E4980A is a precision LCR meter, manufactured by Keysight Technologies. It is specially designed for measurement of various electronic components. Below is the detailed introduction of this product:

1. Main Features

1. Frequency Range: The frequency range of E4980A is from 20Hz to 2MHz (some sources say 20MHz), and it can provide 4-digit resolution measurement within this wide frequency range. If a wider frequency range is required, you can choose E4980AL, whose frequency range covers 300k/500k/1MHz.

2. Basic Accuracy: Whether measuring low impedance or high impedance, E4980A can achieve excellent measurement repeatability and 0.05% basic measurement accuracy, with 7-digit resolution in each range (loss factor resolution is 1ppm).

3. DC Bias: The E4980A is equipped with Enhanced DC Bias Configuration (Option 001) and Rdc Measurement (Option 200) to meet more complex measurement requirements. With Option 001, the DC bias configuration is enhanced, allowing DC bias measurement up to ±40Vrms using the internal voltage source (without Option 001, DC bias measurement can only be performed up to ±2Vrms).

4. Test Signal: The test signal level of the E4980A covers the range from 0.1mVrms to 20Vrms (or 2Vrms in another specification) and from 50μA to 200mArms (or 20mArms in another specification).

5. High-speed Measurement: The E4980A features high-speed measurement capability with a measurement speed up to 5.6ms.

6. List Sweep: E4980A supports up to 201 points for list sweep measurement, which allows you to enter up to 201 automatically measured points of frequency, test signal level or bias level.

7. Connectivity: The E4980A provides general-purpose PC connectivity, including LAN, USB and GPIB interfaces, which significantly improves design and test efficiency.

II. Other Functions

1. Built-in Comparator: The E4980A has a built-in comparator that can output comparison/judgment results, which is used to sort components into up to 10 bins.

2. Automated Measurement: With the optional handler interface and scanner interface, the E4980A can be easily integrated with component handlers, scanners and system controllers to achieve full automation of component testing, sorting and quality control data processing.

3. Material measurement: For material measurement, when used together with the N1500A-005/006 material measurement fixture, the E4980A easily completes the entire measurement process from fixture setup to report generation.

III. Application Scenarios

The E4980A Precision LCR Meter achieves an ideal balance among measurement accuracy, speed and versatility, making it suitable for measuring all kinds of electronic components. Whether at low impedance range or high impedance range, the E4980A delivers ultra-fast measurement speed and excellent measurement performance, and it is an outstanding testing tool necessary for R&D and manufacturing applications of conventional components and materials.

IV. Summary

Keysight E4980A Precision LCR Meter occupies an important position in the field of electronic test and measurement with its high precision, high speed, multi-function and ease of use. It can not only meet the measurement requirements of various components, but also improve design and test efficiency, providing powerful support for engineers.
