Speciications (spec.): Warranted performance. Speciications include guardbands to account for the expected statistical performance distribution, measurement uncertainties, and changes in performance due to environmental conditions. Supplemental information is provided as information that is useful in operating the instrument, but is not covered by the product warranty. This information is classiied as either typical or nominal. Typical (typ.): Expected performance of an average unit without taking guardbands into account. Nominal (nom.): A general descriptive term that does not imply a level of performance. How to Use Tables When measurement conditions fall under multiple categories in a table, apply the best value.

The E4980A provides three types of compensation functions: OPEN compensation, SHORT compensation, and LOAD compensation. Type of compensation Description OPEN compensation Compensates errors caused by the stray admittance (C, G) of the test ixture. SHORT compensation Compensates errors caused by the residual impedance (L, R) of the test ixture. LOAD compensation Compensates errors between the actual measured value and a known standard value under the measurement conditions desired by the user. List sweep Points: There is a maximum of 201 points. Note A parameter selected for one of the two parameters cannot be selected for the other parameter. It is not possible to set up a combination of test signal voltage and test signal current or one of test signal voltage of DC bias signal and test signal current of DC bias. The secondary parameter can be set only with SCPI commands. First sweep parameter (primary parameter): Test frequency, test signal voltage, test signal current, test signal voltage of DC bias signal, test signal current of DC bias signal, DC source voltage. Second sweep parameter (secondary parameter): None, impedance range, test frequency, test signal voltage, test signal current, test signal voltage of DC bias signal, test signal current of DC bias signal, DC source voltage Trigger mode Sequential mode: When the E4980A is triggered once, the device is measured at all sweep points. /EOM/INDEX is output only once. Step mode: The sweep point is incremented each time the E4980A is triggered. /EOM/INDEX is output at each point, but the result of the comparator function of the list sweep is available only after the last /EOM is output. 18 | Keysight | E4980A Precision LCR Meter 20 Hz to 2 MHz, E4980AL Precision LCR Meter 20 Hz to 300 kHz/500 kHz/1 MHz - Data Sheet Comparator function of list sweep: The comparator function enables setting one pair of lower and upper limits for each measurement point. You can select from: Judge with the irst sweep parameter/Judge with the second parameter/Not used for each pair of limits. Time stamp function: In the sequential mode, it is possible to record the measurement starting time at each measurement point by deining the time when FW detects a trigger as 0 and obtain it later with the SCPI command. Comparator function Bin sort: The primary parameter can be sorted into 9 BINs, OUT_OF_BINS, AUX_BIN, and LOW_C_REJECT. The secondary parameter can be sorted into HIGH, IN, and LOW. The sequential mode and tolerance mode can be selected as the sorting mode. Limit setup: Absolute value, deviation value, and % deviation value can be used for setup. BIN count: Countable from 0 to 999999. DC bias signal Table 29.
