Information on this specific configuration – E4980B/001/710/710

The Keysight E4980B/001/710/710 is an E4980B with two blank interface covers on the instrument’s rear panel (option 710). If needed, these can be filled with the handler interface (option 201) and/or the scanner interface (option 301). Information on these can be seen further below in this section.

This model also includes option 001, power and DC bias enhancement.

Option 001 (power and DC bias enhancement) increases test signal voltage and adds the variable DC bias voltage.

Standard – without option 001

• DC bias signal voltage: 0V, 1.5V, 2.0V
• DC bias signal current: unavailable 

With option 001

The Keysight E4980B is a general-purpose LCR meter for incoming inspection of components, quality control, and laboratory use. The E4980B is used for evaluating LCR components, materials, and semiconductor devices over a wide range of frequencies and test signal levels.

With its built-in comparator, the E4980B can output comparison/decision results for sorting components into a maximum of ten bins. Furthermore, by using the handler interface and scanner interface options, the E4980B can be easily combined with a component handler, a scanner, and a system controller to fully automate component testing, sorting, and quality-control data processing.

The E4980B’s list sweep function permits entry of up to 201 frequencies, test signal levels, or bias level points to be automatically measured. The GPIB/LAN/USB interfaces are standard interfaces on the E4980B and enable automatic testing.

Measurement parameters

The E4980B 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
• Vdc-Idc (requires option 001)

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
• Vdc – Direct-current voltage
• Idc – Direct-current electricity

When equipped with the Option 201 Handler Interface, the E4980B 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 E4980B 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.

Please note, the image below shows the scanner interface (option 201) and handler interface (option 301). These options are sold separately. The standard model includes blank covers (option 710) over each slot.
