The E4980AL designation covers the low-frequency configurations of the same instrument — 20 Hz to 300 kHz, 500 kHz, or 1 MHz — and is used only for ordering and shipment; the unit itself is labeled E4980A. The instrument is fully compliant to the LXI Class C specification. As an impedance measurement instrument, the E4980A characterizes capacitors, inductors, and resistive components by reporting parameters such as capacitance, inductance, resistance, reactance, impedance, admittance, conductance, susceptance, and dissipation or quality factor. Its built-in comparator sorts a primary parameter into nine bins plus out-of-bin and auxiliary categories, with a secondary parameter classified HIGH, IN, or LOW, supporting component sorting and pass/fail evaluation. A 201-point list sweep allows a sequence of measurement points to be evaluated automatically. ValueTronics stocks this equipment directly from our own 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is inspected and functionally verified in-house before it ships, while new units leave factory-sealed exactly as received from the manufacturer. That combination of real inventory and hands-on verification is what distinguishes a ValueTronics purchase. ## Brand Heritage Agilent Technologies began as the test-and-measurement arm of Hewlett-Packard, which spun the business off as Agilent Technologies in 1999. In 2014, Agilent's electronic measurement business was established as Keysight Technologies, the brand under which this product line is supported today. ## Compare Other Models in This Series The E4980A and E4980AL share a single hardware platform built around precision four-terminal-pair impedance measurement. The E4980A is the full-range model covering 20 Hz to 2 MHz, while the E4980AL is the ordering designation applied to frequency-limited configurations — 20 Hz to 1 MHz, 500 kHz, or 300 kHz. Because the physical unit is labeled E4980A in every case, the family is best understood as one meter offered at several upper-frequency limits. Across the family the core measurement parameters, four-terminal-pair terminals, compensation functions, and interface set remain common; the configurations differ chiefly in maximum test frequency and in which options can be installed. Each configuration linked below is its own product page with pre-owned-matched pricing. Select the model whose frequency range and installed options match your application, and review that page's specifications and availability for the pre-owned unit you intend to order. The E4980A, as the full 20 Hz to 2 MHz model, is the configuration that accepts the Power and DC Bias enhancement (Option 001), the bias current interface (Option 002), and the entry/standard model options — capabilities the frequency-limited configurations do not accept per the installable-options table. The primary difference across the family is the upper test-frequency limit: 2 MHz for the E4980A, and 1 MHz, 500 kHz, or 300 kHz for the E4980AL frequency options 100, 050, and 030 respectively. The comparison table below lists each configuration's frequency range alongside its ordering and product model numbers. Option availability also differs by configuration. The installable-options table shows that the Power and DC Bias enhancement, bias current interface, and entry/standard model options apply only to the 2 MHz model, while DC resistance measurement is supplied by default on the frequency-limited units. The handler and scanner interfaces are installable across all configurations.
