2.1 Introduction
Thank you for purchasing AT281x LCR meter.
The Applent AT281x is a general-purpose LCR meter for incoming inspection of
components, quality control, and laboratory use.
The AT281x is used for evaluating LCR components, materials, and semiconductor
devices over a wide range of frequencies (10 Hz to 300 kHz) and test signal levels
(0.01Vrms to 2 Vrms).
With its built-in comparator, the AT281x can output comparison/decision results for
sorting components into a maximum of ten bins. Furthermore, by using the handler
interface, the AT281x can be easily combined with a component handler, and a system
controller to fully automate component testing, sorting, and quality-control data
processing.
The AT281x’s list sweep function permits entry of up to 10 frequencies or test signal
levels points to be automatically measured.
