E363X: Power to the Bench Key Features
Agilent E3631A - E3634A power
supplies are designed for bench
automation in R&D design and QA
verification. Even at value prices, these
power supplies deliver great features
and power. Their low noise and
excellent regulation are essential for
R&D engineers who need to evaluate
assemblies or applications, and for
test engineers who need to develop
repair strategies for production.
•
Hybrid regulation techniques create a
denser, lighter package and a smaller
footprint—key considerations when
bench space is at a premium. Front
panel output connections enable
ease-of-use, while GPIB and RS-232
interfaces make for a versatile power
source.

Built-in GPIB and RS-232
interfaces
Dual-range outputs in the E3632A,
E3633A, and E3634A for great
coverage of voltage and current
for various applications
Triple output on the E3631A
allows for flexibility in mixedsignal applications (such as
providing analog and digital bias
power) and for tracking feature ±
25V outputs

Power
The Agilent E3640A - E3649A
power supplies fill the gap between
manual bench power supplies and
high performance system supplies,
offering unmatched performance
and functionality at a great price.
They’re designed for moderate speed
test where automation is important
and throughput is not critical. These
single- and-dual-output, dual-range
power supplies are ideal for contract
manufacturers and OEMs who need
to perform basic electronic functional
tests on a variety of products quickly
and economically.

All models support GPIB and RS-232
for quick connectivity. SCPI (Standard
Commands for Programmable
Instruments) keeps programming
fast and simple. Less than 90 ms
output settling time keeps throughput
high without the need for a down
programmer. Up to five store/recall
states help minimize programming
time while accelerating test. Remote
sensing capability ensures output
stability with longer leads.

6600: High Performance
System Solutions
Do you need a power supply with
excellent performance and built-in
measurement capability? Agilent
6600 Series systems are ideal for
production test applications where
throughput is critical and rack space is
at a premium. These one-box solutions
reduce integration time and increase
system reliability, and offer a variety of
features to reduce test costs, increase
test speed, and lower the cost of
integration and ownership.
Compared to the “E” series, output
transitions are over ten times
faster, measurement times are up
to five times faster, and program
response and command processing
times are accelerated. The builtin DMM allows for more accurate
measurement capability. Throughput
is significantly enhanced via the
active down programmer that can
quickly remove any energy from the
unit under test when the output is
programmed to zero. Extended remote
sensing capability compensates for
voltage drops in load leads of up to 50
percent of the rated output voltage,
eliminating troublesome sourcing and
measurement inaccuracies due to
resistance in the load wiring.
