6630B Series Single-Output,

80-100 W GPIB Power Supplies

Data Sheet

Speed and accuracy for test optimization

This series of linear-regulated 80-100 W

DC power supplies is designed to max-

imize the throughput of DUTs through

the manufacturing test process. Both

programming and measurement

features including stored states and

status reporting. Programming is

done using industry standard SCPI

commands via the GPIB or RS-232.

Test system integration is further

simplified by using the VXIplug&play

drivers. The optional relays simplify

system design and troubleshooting.

The optional front panel binding posts

make the 6630B series convenient

on the R&D lab bench. The built-in

microamp measurement system helps

the engineer to easily and accurately

monitor the output voltage and current

without a complicated test setup.
