The Agilent HP 6653A is a single output, series pass regulated power supply, with an internal GPIB interface and SCPI programming. The Agilent HP 6653A provides many talker/listener functions including remote programming of voltage and current with feedback of actual measured output values.

Programming of the dc output and the protection features can be done either from the front panel or using industry standard SCPI commands, via the GPIB. Using the serial link, up to 16 power supplies can be connected through one GPIB address. Test system integration can be further simplified be using the VXIPlug&Play drivers. The output voltage and current can also be controlled with analog signals. This is helpful for certain types of noisy environments, and also immediate reactions to process changes.

Lab bench use is enhanced by the fan speed control, which helps to minimize the acoustic noise.
