Great Performance,
Outstanding Price
With the output power of 30 to
100 W, the Agilent E364xA Series
programmable DC power supplies
provide great performance at a great
price. All ten models deliver clean
power, excellent regulation, fast
transient response and built-in GPIB
and RS-232 interfaces. They are
designed to meet the needs of R&D
design verifi cation, production testing,
QA verifi cations, and other demanding
applications with Agilent
Technologies’s quality and reliability.
Steady Output
With 0.01 percent load and line
regulation, Agilent E364xA power
supplies are able to maintain a steady
output when power line and load
changes occur. They also specify
normal mode voltage noise and low
common mode current noise. The
low normal mode noise specifi cation
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. The easy-to-use SCPI
(Standard Commands for
Programmable Instruments) allow fast
and simple programming procedures.
Besides, the user manual provides
suffi cient information on programming
for all end users, from beginners to
veterans.
Broad Support
VXI plug and play software drivers are
available for Agilent VEE, National
Instruments LabViewTM and
LabWindowsTM. With these drivers,
integration of the E364xA into your
system can never be any easier. 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 set the
output at your desired resolution
without any effort. Also, both voltage
and current levels can be set to a
maximum resolution of 10 mV/1 mA
from the front panel. In addition, you
can store and recall for up to fi ve
complete power supply setups using
the internal non-volatile memory.
The output on/off button sets the
output to zero. If you own a dual
output model, you can view two
voltages or currents that are displayed
simultaneously.
Versatile Power
Agilent E364xA power supplies give
you the fl exibility to select from dual
output ranges. Output load is
protected against overvoltage, which
can be easily monitored and adjusted
from the front panel and remote
interface. Remote sensing is available
in the rear terminal to eliminate errors
caused by 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 panel. New front panel binding
posts allow you to use safety test
leads as well as conventional banana
clips and stripped wires. An optional
rackmount kit is available. The Agilent
E364xA Series employs a cooling
fan with automatic speed control to
reduce the acoustic noise.
