Agilent / HP / Keysight 4278A
4278A 1 kHz/1 MHz Capacitance Meter
Description
This unit is a high-speed, highly reliable, precision test instrument aimed at incoming/outgoing capacitor inspection applications on the production line and in quality control.
This improves test efficiency by performing comparative measurements of low to medium value capacitors(up to 200µF - a range that covers most ceramic and film capacitors).
It's standard measurement frequencies and oscillator output level are 1KHz/1MHz and from 0.1V to 1V in 0.1V steps, respectively.
It's built-in comparator function gives you the ability to sort parts into ten bins.
A high-speed HP-IB interface and an optional handler interface are available for combining it with an automatic handler and an external computer, to build a total solution for automatic testing and data acquisition and analysis.
