Keysight 6824A DC Power Supply and Amplifier is a general purpose instrument useful in any laboratory engaged in research and development of electronic systems or components. The 6824A power supply and amplifier can operate in one of two basic operating modes: power supply or amplifier. Terminals on the rear barrier strip permit access to various control points within the unit to further expand the operating capabilities of the Keysight 6824A. The resulting flexibility lends the 6824A to an almost unlimited number of applications.
The Keysight 6824A can be made to function as a regulated dc power supply by setting the front panel MODE switch to the SUPPLY position. The supply can furnish either a Constant Voltage output or a Constant Current output. The dc output is bi-polar and is continuously adjustable from its maximum rated positive value to an equal negative value; smoothly through zero with no polarity switch.
As a power amplifier, the 6824A has a high signal-to-noise ratio (80db at full output) and an adjustable gain of from 0 to 10 (20 db). The output distortion is low – less than 0.02% at 1 KHz. The amplifier contains a push-pull output stage that can furnish either a Constant Voltage output or a Constant Current output.
The Keysight 6824A DC Power Supply and Amplifier was originally Hewlett Packard 6824A DC Power Supply and Amplifier, then became Agilent 6824A DC Power Supply and Amplifier.
