Agilent E3640A – E3649A
Programmable dc Power Supplies

Data Sheet

Great Performance, Outstanding Price

With 30 to 100W of output power,
the Agilent E364xA-series of
programmable dc power supplies
provide great performance at a great
price. All ten models deliver clean
power, dependable regulation, fast
transient response and built-in GPIB
and RS-232 interfaces. They’re
designed to meet the needs of R&D
design verification, production
testing, QA verifications and other
demanding applications with Agilent
Technologies’ quality and reliability.

Steady Output

With 0.01 percent load and line
regulation, Agilent E364xA power
supplies keep output steady when
power line and load changes occur.
They also specify low normal mode
voltage noise and low common mode
current noise. The low normal mode
noise specification assures clean
power for precision circuitry
applications, and the low common
mode current provides isolation from

power line current injection. Agilent
E364xA power supplies specify less
than 90 msec of voltage settling time
at any output load condition.

Remote Interface

Agilent E364xA power supplies
support any PC with a GPIB
(IEEE-488) card or RS-232 interface.
Every model ships standard with
both GPIB and RS-232. Easy-to-use
SCPI (Standard Commands for
Programmable Instruments) keeps
programming fast and simple. The
user manual provides information for
beginning programmers, yet includes
enough detail to help veteran
programmers as well.

Broad Support

VXIplug&play software drivers
are available for Agilent VEE and
National Instruments LabView™
and LabWindows™, simplifying
integration of the E364xA into
your test system. The drivers are
supported under Microsoft

®

Windows 98®and NT.

Front Panel Operation

An easy-to-use rotary knob and self­guiding keypads allow you to quickly
and easily set output at the resolution
you need. Voltage and current levels
can be set to a maximum resolution of
10 mV/1 mA from the front panel. Up
to five complete power supply setups
can be stored and recalled from the
internal non-volatile memory. The
output on/off button sets the output
to zero. Dual output models allow
two voltages or currents to be
displayed simultaneously.

Versatile Power

Agilent E364xA power supplies give
you the flexibility to select from dual
output ranges. Output load is
protected against overvoltage, which
is easily monitored and adjusted from
the front panel and remote interface.
Remote sensing is available in the rear
terminal to eliminate errors due to
voltage drops on the load leads. These
power supplies offer new versatile
binding posts on the front panel and

screw-type terminals on the rear
