All specifications apply to the conditions of a 0 to 55 °C temperature range, unless
otherwise stated, and 30 minutes after the instrument has been turned on.
Definitions
Specifications (spec.): Warranted performance. Specifications 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 classified
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.
When measurement conditions fall under multiple categories in a table, apply the
best value.
How to Use Tables

Relative accuracy
Relative accuracy includes stability, temperature coefficient, linearity, repeatability, and
calibration interpolation error. Relative accuracy is specified when all of the following
conditions are satisfied:
– Warm-up time: 30 minutes
– Test cable length: 0 m, 1 m, 2 m, or 4 m (Keysight Technologies, Inc. 16048A/D/E)
– A “Signal Source Overload” warning does not appear.
When the test signal current exceeds a value in table 11 below, a “Signal Source
Overload” warning appears.

Compensation function
Table 28. 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
fixture.
SHORT compensation
LOAD compensation
Compensates errors caused by the residual impedance (L, R) of the test
fixture.
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.
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.
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.
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
The secondary parameter can be set only with
SCPI commands.
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 first 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 defining 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.
