FG-281 Function Generator

FG-281

Stock only

The FG-281 is a function generator using DDS (Direct Digital Synthesis) for superior frequency stability. Possible to output sign wave and square wave at wide oscillation range from 10mHz to 15Mhz. A 10-key keypad provides user-friendly operation even though various functions are available. Possible to memorize 9 kinds of panel settings and they can be recalled easily. RS-232C and GP-IB interfaces are available as standard and enable to be controlled by PC (full remote control).

Specification
