Description
The Agilent 6644A is one of the 664x series of 200 Watt, single output, series pass regulated power supplies, with an internal GPIB interface and SCPI programming. These models provide many talker/listener functions including remote programming of voltage and current with feedback of actual measured output values. 16 supplies can be connected to one GPIB interface via a serial link connection.
This series of 200 W linear-regulated dc power supplies is designed to maximize the throughput of DUTs through the manufacturing test process with fast up and down programming time.
Valuable assemblies can be destroyed by a minor component failure that can allow a surge of voltage or current to flow to the DUT. Fast protection features, including fast crowbar, mode crossover protection, and the ability to connect the protection circuitry of multiple power supplies can increase production yield.
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.
