6630B Series Single-Output,
80-100 W GPIB Power Supplies
Data Sheet
Speed and accuracy for test optimization
– Fast, low-noise outputs
– Programmable active down-programmer sinks the full rated current
– Dual-range, precision low current measurement
– Optional isolation and polarity reversal relays
– Built-in measurements and advanced
programmable features
– Protection features to ensure DUT safety
The Keysight Technologies, Inc. series of linear-regulated 80-100 W DC power supplies is
designed to maximize the throughput of DUTs through the manufacturing test process.
Both programming and measurement are optimized for speed. The active downprogrammer
can sink up to the full rated current of the power supply, which quickly brings the power
supply output to zero volts. The 6630B series offers many advanced programmable features
including stored states and status reporting. Programming is done using industry standard
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.

Keysight Models: 6631B, 6632B 6633B, 6634B
Supplemental characteristics
for all model numbers
DC floating voltage: Output terminals can be floated up to ± 240
VDC maximum from chassis ground
Remote sensing: Up to two volts dropped in each load lead. Add
2 mV to the voltage load regulation specification for each one volt
change in the positive output lead due to load current change.
Command processing time: Average time required for the output
voltage to begin to change following receipt of digital data is 4 ms
for the power supplies connected directly to the GPIB. (Display
disabled).
Output programming response time: The rise and fall time
(10/90% and 90/10%) of the output voltage is less than 2 ms (400
µs in fast mode). The output voltage change settles within 1 LSB
(0.025% x rated voltage) of final value in less than 6 ms (2 ms in
the fast mode).
GPIB interface capabilities: IEEE-488.2, SCPI command set, and
6630A Series programming compatibility
