# Keysight E4980B Precision LCR Meter, 20 Hz to 2 MHz # Keysight E4980B Precision LCR Meter, 20 Hz to 2 MHz ## Key Features At A Glance - Test frequency from 20 Hz to a model-dependent maximum of 300 kHz, 500 kHz, 1 MHz, or 2 MHz across the series - Four-terminal-pair measurement of L, C, R, Z, D, Q, G, B, Y and phase in series or parallel equivalent-circuit models - Basic measurement accuracy to 0.05% (varies with measurement-time mode, frequency, and signal level per accuracy tables) - GPIB (IEEE-488), USB (USBTMC/USB488, USB 2.0), and 10/100BaseT LAN interfaces standard; LXI Class C compliant - OPEN, SHORT, and LOAD compensation with auto/manual impedance ranging and up to 256-measurement averaging - List sweep up to 201 points plus comparator bin sort (9 BINs) for component sorting - Optional Power and DC Bias enhancement (Option 001) adds up to 15 Vrms signal, variable DC bias, and Vdc-Idc measurement - Optional handler (Option 201) and scanner (Option 301) interfaces, up to two interface slots on the rear panel The E4980B and E4980BL are precision LCR meters that measure the impedance characteristics of passive components and materials using a four-terminal-pair configuration. The E4980B covers a test frequency range of 20 Hz to 2 MHz. The E4980BL provides the same core measurement architecture with an upper frequency limit set by its installed frequency option: 20 Hz to 300 kHz (option -032), 20 Hz to 500 kHz (option -052), or 20 Hz to 1 MHz (option -102). An LCR meter applies a known test signal to a device under test and derives the component's inductance, capacitance, resistance, and related parameters from the resulting voltage and current. This series measures a broad parameter set, including Cp/Cs, Lp/Ls, D, Q, G, Rp, Rs, R-X, Z-phase, G-B, and Y-phase, with both parallel and series equivalent-circuit models selectable. A deviation measurement function can output the deviation from a reference value or the percentage of deviation from that reference. We hold our inventory in our own 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, which lets us control quality and fulfillment directly rather than relaying orders to a third party. ## Brand Heritage These instruments are manufactured by Keysight Technologies. Keysight's test and measurement heritage traces back to Hewlett-Packard, whose measurement business was spun off as Agilent Technologies in 1999; Agilent's electronic measurement division then became Keysight Technologies in 2014. ## Compare Other Models in This Series The E4980B/E4980BL series is a family of precision LCR meters built on a common four-terminal-pair measurement architecture and parameter set, differentiated primarily by test frequency coverage. The E4980B is the 20 Hz to 2 MHz model. The E4980BL is offered with frequency options that set its upper limit to 300 kHz, 500 kHz, or 1 MHz. Across the family, the measurement functions, compensation modes, list sweep, comparator, and interface options are shared, so the choice between models is driven by the highest test frequency an application requires and by which options (such as the Power and DC Bias enhancement) are installed. Each new model below links to its own dedicated product page with condition-matched pricing. Select the model and frequency configuration that fits your application, then review that page for its specific new availability and configuration. The E4980B is the top-frequency member of the series, providing test frequencies up to 2 MHz with frequency resolution down to 1 kHz in the 1 MHz to 2 MHz segment and as fine as 0.01 Hz at the low end of its range. The defining difference among these models is the upper test frequency limit: 2 MHz for the E4980B, versus 1 MHz, 500 kHz, or 300 kHz for the E4980BL depending on its installed frequency option (-102, -052, or -032). The comparison table that follows lists each model's frequency coverage alongside the shared measurement and interface specifications. Configuration options also distinguish individual units. The Power and DC Bias enhancement (Option 001) is installable on the E4980B but is shown as not installable on the E4980BL, while the handler (Option 201) and scanner (Option 301) interfaces are installable on both. Refer to each model's row in the table to confirm which capabilities apply to that configuration.
