Agilent 6650A Series Single-Output,
500 W DC Power Supplies, GPIB
Data Sheet
Speed and accuracy for test optimization
This series of 500 W linear-regulated
DC power supplies is designed to max-
imize 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
causes a surge of current to flow
into the DUT. Fast protection fea-
tures, 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 con-
nected 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 sig-
nals. This is helpful for certain types of
noisy environments, and also immedi-
ate reactions to process changes.
Lab bench use is enhanced by the fan
speed control, which helps to minimize
acoustic noise.
• Fast, low-noise outputs
• Analog control of output voltage and current
• Fan-speed control to minimize acoustic noise
• Built-in measurements and advanced programmable features
• Protection features to ensure DUT safety

Supplemental characteristics
for all model numbers
DC floating voltage: Output terminals
can be floated up to ± 240 VDC from
chassis ground
Remote sensing: Up to half the rated
output voltage can be dropped in each
load lead. The drop in the load leads
subtracts from the voltage available
for the load.
Command processing time: Average
time required for the output voltage to
begin to change following receipt of
digital data is 20 ms for the power
supplies connected directly to the GPIB
Output programming response time:
The rise and fall time (10/90% and
90/10%) of the output voltage is less
than 15 ms. The output voltage change
settles within 1 LSB (0.025% x rated
voltage) of final value in less than 60 ms.
Down programming: An active down
programmer sinks approximately 20%
of the rated output current
Modulation: (Analog programming of
output voltage and current)
