Agilent 6641A Data Sheet

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.

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)
Input Signal: 0 to –5 V
Input Impedance: 10 k Ohm nominal

ac Input: (ac input frequency 47 to 63 Hz)

The preceding page(s) are an excerpt from the 2002-2003 Power Products Catalog.
We hope that these pages supply the information that you currently need.
If you would like to have further information about the extensive selection of
Agilent dc power supplies, ac sources, and dc electronic loads, please visit

www.agilent.com/find/powerto print a copy of the complete Power Products

catalog, or to request that a copy be sent to you. You will also find a lot of other
useful information on this web site.

In the full Power Products Catalog, you will find that Agilent offers much more
than basic power generation. If you need basic, clean, power for your lab bench,
it’s there. But in each product category, we’ve also integrated the capabilities
that you need for a complete power solution, including extensive measurement
and analysis capabilities.

Please give us a call at your local Agilent Technologies sales office,
or call a regional office listed below, for assistance in choosing or using
Agilent power products.
