Keysight E4980BL/052/710/710 – Precision LCR Meter (20Hz to 500kHz)

The Keysight E4980BL precision LCR meter is an industry-standard LCR meter that combines accuracy, speed, and versatility for a wide range of component measurements. It is an essential tool for general R&D and manufacturing tests of components and materials, offering fast measurement speed and exceptional performance across both low and high-impedance ranges.

The versatile LAN, USB, and GPIB PC connectivity enhance your design and test productivity. For materials measurements, the E4980BL paired with the optional N1500A-005/006 materials measurement suite simplifies the entire process, from fixture setup to report generation.

This product is offered in three frequency ranges, with maximum frequencies ranging from 300kHz to 1MHz. Part numbers for each can be seen below:

• E4980BL/032/710/710
• Frequency range: 20Hz to 300kHz
• E4980BL/052/710/710
• Frequency range: 20Hz to 500kHz
• E4980BL/102/710/710
• Frequency range: 20Hz to 1MHz

Please note, the 710 in the part numbers above indicates option 710. These are blank, rear panel interface covers and if needed, can be replaced with the handler interface (option E4980BL-201) and/or scanner interface (option E4980BL-301).

Measurement parameters

The E4980BL can be used to measure the following:

• Cp-D, Cp-Q, Cp-G, Cp-Rp
• Cs-D, Cs-Q, Cs-Rs
• Lp-D, Lp-Q, Lp-G, Lp-Rp, Lp-Rdc
• Ls-D, Ls-Q, Ls-Rs, Ls-Rdc
• R-X
• Z-θd, Z-θr
• G-B
• Y-θd, Y-θr

The items notated above refer to the following:

• Cp – Capacitance value measured with parallel-equivalent circuit model
• Cs – Capacitance value measured with series-equivalent circuit model
• Lp – Inductance value measured with parallel-equivalent circuit model
• Ls – Inductance value measured with series-equivalent circuit model
• D – Dissipation factor
• Q – Quality factor (inverse of D)
• G – Equivalent parallel conductance measured with parallel-equivalent circuit model
• Rp – Equivalent parallel resistance measured with parallel-equivalent circuit model
• Rs – Equivalent series resistance measured with series-equivalent circuit model
• Rdc – Direct-current resistance
• R – Resistance
• X – Reactance
• Z – Impedance
• Y -Admittance
• θd – Phase angle of impedance/admittance (degree)
• θr – Phase angle of impedance/admittance (radian)
• B – Susceptance

When equipped with the Option 201 Handler Interface, the E4980BL can interact with the handler. The 36-contact Amphenol connector on the rear panel is used to connect the interface, through which control input/output signals and comparator bin sorting result signals are communicated.

Option 201 outputs signals that indicate the end of a measurement cycle, the result of bin sorting by the comparator, and the result of Go/No-Go test by the list sweep comparator. In addition, the instrument accepts input of external trigger and key-lock signals. You can use these signals to easily integrate the instrument with a component handler or system controller. This means that you can fully automate such tasks as component inspection, component sorting, and processing of quality management data for higher manufacturing efficiency.

When equipped with the Option 301 Scanner Interface, the E4980BL supports multi-channel correction. The 14-contact Amphenol connector on the rear panel is used to connect the interface, through which control output signals and multi-channel correction channel selector signals are communicated.

With option 301, it is possible to store and use up to 128 sets of correction data (OPEN, SHORT, and LOAD) for up to 201 user-defined test frequencies. These 128 sets of correction data can be used for each measurement using the multi-channel correction function.

The instrument can correct stray admittance, residual impedance, and other errors for each channel from the calibration plane to the connection contacts at the device. Therefore, option 301 of the can accurately measure impedance values without any degradation of repeatability, or differences between channels. Timing synchronization is also provided.
