HP 4278A 1 kHz/1 MHz Capacitance Meter

[ Summary ][ Features ][ Specifications ][ Key Literature ][ Ordering ][ Assistance ][ Related ]
The HP 4278A 1kHz/1MHz capacitance meter is a high-speed, highly reliable, precision test instrument aimed at incoming/outgoing capacitor inspection applications on the production line and in quality control. The HP 4278A will improve test efficiency by performing comparative measurements of low to medium value capacitors (up to 200uF -- a range that covers most ceramic and film capacitors).

The HP 4278A's standard measurement frequencies and oscillator output levels are 1 kHz/1MHz and from 0.1V to 1V in 0.1V steps, respectively.

The built-in comparator function of the HP 4278A 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 the HP4278A with an automatic handler and an external computer, to build a total solution for automatic testing and data acquisition and analysis.
