Great Performance,
Outstanding Price
With the output power of 30 to 100 W, the
Keysight Technologies, Inc. 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 verication, production testing,
QA verications, and other demanding
applications with Keysight Technologies’s
quality and reliability.
Steady Output
With 0.01 percent load and line regulation,
Keysight 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 specication assures
clean power for precision circuitry applica-
tions, and the low common mode current
provides isolation from power line current
injection. Keysight E364xA power supplies
specify less than 90 msec of voltage
settling time at any output load condition.
Remote Interface
Keysight 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 sufcient infor-
mation on programming for all end users,
from beginners to veterans.
Broad Support
VXI plug and play software drivers are
available for Keysight VEE, National Instru-
ments LabView and LabWindows. 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 self-guiding
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 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
Keysight E364xA power supplies give you
the 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 avail-
able 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 conven-
tional banana clips and stripped wires. An
optional rackmount kit is available. The
Keysight E364xA Series employs a cooling
fan with automatic speed control to reduce
the acoustic noise.
