Intergrated System
The iX Series II represents a new generation of AC
and DC power source that addresses increasing
demands on test equipment to perform more
functions at a lower cost. By combining a exible
AC/DC power source with a high performance
power analyzer, the iX Series II systems are
capable of handling complex applications that
have traditionally required multiple instruments.

The sleek integrated approach of the iX Series
II avoids the cable clutter that is commonly
found in AC test systems. The i/iX Series II is
rackmountable with a 4U chassis design. All
connections are made internally and the need for
external digital multimeters, power harmonics
analyzer and current shunts or clamps is
completely eliminated.

Using a state of the art digital signal processor in
conjunction with precision high resolution A/D
converters, the iX Series II provides more accuracy
and resolution than can be found in some
dedicated harmonic power analyzers. Since many
components in the iX Series II are shared between
the AC/DC source and the power analyzer, the
total cost of the integrated system is less than the
typical cost of a multiple unit system.

For less demanding applications, the i Series II
provides similar output and transient capabilities
as the iX Series II, as well as basic measurements.

Easy To Use Controls
Both the iX Series II and i Series II are
microprocessor controlled and can be operated
from an easy to use front panel keypad. Functions
are grouped logically and are directly accessible
from the keypad. This eliminates the need to
search through various levels of menus and/or
soft keys. A large analog control knob can be
used to quickly slew output parameters. This

knob is controlled by a dynamic rate change
algorithm that combines the benets of precise
control over small parameter changes with quick
sweeps through the entire range.

Applications
With precise output regulation and accuracy,
the iX Series II AC and DC sources address
many application areas for AC and DC power
testing. The iX also provides a high load current
capability, multi or single phase output modes,
and built-in power analyzer measurements.
Additional features including line distortion
simulation (LDS), arbitrary waveform generation,
and programmable output impedance address
requirements for product quality and regulatory
compliance testing.

Product Evaluation and Test
Increasingly, manufacturers of electronic
equipment and appliances are required to fully
evaluate and test their products over a wide
range of input line conditions. The built-in output
transient generation and readback measurement
capability offers the convenience of an easy to
use and integrated test system.

Avionics
With an output frequency range to 1000 Hz,
up to 150 VRMS, the iX Series II is well suited
for aerospace applications. Precise frequency
control and accurate load regulation are key
requirements in these applications. The standard
IEEE-488 control interface and SCPI command
language provide for easy integration into existing
ATE systems. Since the iX Series II can eliminate
the need for additional pieces of test equipment
and only occupies 7 inches of rack space (4U),
it signicantly saves cost and space. Options are
available for popular avionics test routines such
as: DO-160, ABD- 0100, MIL-STD-704A-F, Boeing
7E73B-0147, and Airbus test routines.

i/iX Series II

Regulatory Testing

As governments are moving to enforce product
quality standards, regulatory compliance testing
is becoming a requirement for a growing
number of manufacturers. The iX Series II is
designed to meet AC source requirements for
use in Euronorm EN 61000 compliance testing.
For icker testing, the programmable output
impedance capability of the 3001iX, 5001iX
and 15003iX can be used to create the required
IEC 725 reference impedance. Run IEC61000­4-11, IEC61000-4-14 and IEC61000-4-28 test
programs.

Multi-Box Congurations
For high power applications, two or three 5001i/
iX chassis can be combined to provide 10 to 15
kVA of single or three phase power. A 9003iX,
15003iX or 15003i three phase conguration can
be ordered with the MODE-iX option. This option
allows automatic switching between single or
three phase output mode. In single phase mode,
all current is available on phase A.

High Crest Factor
With a crest factor of up to 5:1, the i/iX Series II
AC source can drive difcult nonlinear loads with
ease. Since many modern products use switching
power supplies, they have a tendency to pull high
repetitive peak currents. The 5001iX can deliver
up to 110 Amps of repetitive peak current to
handle such loads.

Remote Control
Standard IEEE-488 and RS232C remote control
interfaces allow programming of all instrument
functions from an external computer. The
popular SCPI command protocol is used for
programming. Drivers for several popular
instrumentation programming environments
are available to facilitate systems integration of
the i/iX Series II. Instrument drivers for popular
programming environments such as National
Instruments LabView™ are available to speed up
system intergration.`

Application Software

the iX and i Series II¹ . This software provides
easy access to the power source’s capabilities
without the need to develop any custom code.

Harmonic Waveform Generation
Using the latest DSP technology, the iX Series
II controller is capable of generating harmonic
waveforms to test for harmonics susceptibility
of a unit under test. Included is a Graphical User
Interface program that can be used to dene
harmonic waveforms by specifying amplitude and
phase for up to 50 harmonics. The waveform
data points are generated and downloaded by
the GUI to the AC source through either the USB,
IEEE-488, RS232C bus or LAN and remain in
nonvolatile memory. Up to 200 waveforms can
be stored and given a user dened name for easy
recall.

The three phase conguration iX Series II
offers independent waveform generation on
each phase allowing three phase anomalies to
be programmed. It also allows simulation of
unbalanced harmonic line conditions.

Harmonic waveform, Fund., 3rd, 5th, 7th, 9th,11th and 13th.

Two hundred user dened waveforms.

Arbitrary Waveform Generation
[iX Series II only]

Using the provided GUI program or custom
software, the user also has the ability to dene
arbitrary AC waveforms. The arbitrary waveform
method of data entry provides an alternative
method of specifying AC anomalies by providing
specic waveform data points. The GUI program
includes a catalog of custom waveforms. It also
allows real-world waveforms captured on a digital
oscilloscope to be downloaded to one of the
many AC source’s waveform memories.

Arbitrary waveform capability is a exible way of
simulating the effect of real-world AC power line
conditions in both engineering and production
environments.

iX and i Series II -
AC and DC Transient Generation

The iX and i Series II controllers have a powerful
AC and DC transient generation system that
allows complex sequences of voltage, frequency
and waveshapes to be generated. This further
enhances the i/iX’s capability to simulate AC line
conditions or DC disturbances. When combined
with the multi phase arbitrary waveform
capabilities, the AC and DC output possibilities
are truly exceptional. In three phase i/iX system
congurations, transient generation is controlled
independently yet time synchronized on all
three phases. Accurate phase angle control and
synchronized transient list execution provide
unparalleled accuracy in positioning AC output
events.

Transient programming is easily accomplished
from the front panel where clearly laid out menu’s
guide the user through the transient denition
process. The front panel provides a convenient
listing of the programmed transient sequence and
allows for transient execution, Start, Stop, Abort
and Resume operations.

User dened transient sequences can be saved
to nonvolatile memory for instant recall and
execution at a later time. The included Graphical
User Interface program supports transient
denitions using a spreadsheet-like data entry
grid. A library of frequently used transient
programs can be created on disk using this GUI
program.

Transient List Data Entry from the front panel

Two hundred user dened waveforms.
