Manual E4980A Datasheet Supplemental Document Additional Information
The Keysight E4980A Precision LCR Meter offers the industry's highest accuracy and repeatability from 20 Hz to 2 MHz, fast measurement speed, and outstanding performance at both low and high impedance. As a follow-up to Keysight's market-leading 4284A, the compact E4980A includes a modern PC interface and is five times faster, resulting in enhanced productivity and a lower cost of test.

The unit's high speed (5.6 ms at 1 MHz) improves test throughput and increases production yields, allowing manufacturers to make lower-cost devices. And the meter's support for LAN, USB, and GPIB, as well as powerful test signal support (20 Vrms signal, 40 V DC bias), makes it easier to manage multiple instrument setups and improves data collection time.

Additional features built into the E4980A include support for 40 A DC bias current source for conducting highly accurate and efficient DC current-biased inductance measurements, a DC resistance / voltage / current measurement readout for performing simultaneous evaluations of DC characteristics, and 10 V DC source output port for evaluating three-terminal devices.

For users that do not require the ultimate measurement speed in a short length of time, the economical E4980A with option 005 is available. This version offers the same level of accuracy only with 2 to 5 times less speed than the standard model, yet it is still faster than the 4284A. For testing power inductors and transformers, choose Option 002, 42841A, and 42842A to get up to 20 A dc bias current.
