This 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
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.

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 compatability
Measurement Time: Average time to
make a voltage or current measurement
is 50 ms.
Input Power (full load): 3.5 A, 250 W
Regulatory Compliance: Complies with
EMC directive 89/336/EEC (ISM 1B).
Warranty Period:One year
Size: 425.5 mm W x 88.1 mm H x
364.4 mm D (16.8 in x 3.5 in x 14.3 in).
