This chapter provides the basic procedures for operating the E4980A/AL and
describes names and functions of the front panel, rear panel, and screen
display.
Product Introduction
The Keysight E4980A/AL is a general-purpose LCR meter for incoming
inspection of components, quality control, and laboratory use. The E4980A/AL
is used for evaluating LCR components, materials, and semiconductor devices
over a wide range of frequencies (20 Hz to 300 kHz/500 kHz/1 MHz/2 MHz)
and test signal levels (0.1 mVrms to 2 Vrms, 50 A to 20 mArms). With Option
001, the E4980A’s test signal level range spans 0.1 mV to 20 Vrms, and 50 A
to 200 mArms. Also, the E4980A with Option 001 enables up to 40-Vrms DC
bias measurements (without Option 001, up to 2 Vrms), DCR measurements,
and DC source measurements using the internal voltage source.
The E4980A/AL offers C-D measurement with a basic accuracy of 0.05% (C),
0.0005 (D) at all frequencies with seven-digit resolution (the dissipation factor
resolution is 1 ppm) in every range.
With its built-in comparator, the E4980A/AL 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 E4980A/AL 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 E4980A/AL’s list sweep function permits entry of up to 201 frequencies,
test signal levels, or bias level points to be automatically measured.
The GP-IB/LAN/USB interfaces are standard interfaces on the E4980A/AL and
enable automatic testing.
