The Avermetrics™ Test and Measurement System
has been engineered from the ground up for production line testing of electronic products, subassemblies,
boards, and components. It was designed by an engineering team with extensive product development and
testing experience, with performance and the total cost
of testing as clear design criteria.
mands via Telnet. The XOS operating system interprets
these commands, routes them to the proper module
or modules, collects the results, and sends them back
to the host computer in an easy-to-parse XML format.
Literally any programming language and operating
system that can open a networking socket will support
XOS and this system.
This system, and the currently available range of plugin modules, offers a wide range of test capabilities,
from professional, semi-professional, and consumer
audio product testing, to basic board level tests, to process control, and more. New modules to add new tests
are being added to the library every day.

Modular System
This is a modular system using a custom 1U rack
designed to hold up to 4 modules. The system is highly
scalable: Racks may be interconnected using the
AVERLINK™ connectors on the back of each rack unit;
up to 64 rack units holding up to 254 modules can be
connected in a single system. Internally, each module
has an array of processors, and the system is organized
as a large, interconnected two-dimensional array of
these processors in a distributed intelligence configuration. Because each module is intelligent it does its
own analysis, so tests across multiple modules occur in
parallel, significantly reducing testing time.
Communication
XOS™ is an XML-based operating system that is at
the core of the test system. To define tests or do other
operations, a host computer sends simple XML com-
Avermetrics supplies documentation, C++ classes that
handle all aspects of communication with the system
and parsing of XML commands and results, and example applications (with complete source code) to get you
started. One of those example applications, AverTest,
provides full-featured test execution using simple XML
test and limit definition files so you can start testing on
the production line right away.
Future Proof
The system supports a complete Device Firmware Update capability so new features and updated firmware
can be programmed into existing systems in the field,
with no downtime. Adding new tests and more channels is as simple as plugging new modules and racks
into an existing system. Your investment in testing
never goes obsolete.
Modules
Currently, there are six different modules available to
test audio and analog signals, and to control process
operation and interact with external sensors and digital signals. More information and pricing for each of
these modules is below.

9140 1U Rack Unit
4021 Analog Audio Input Module
Every system has at least one 9140 Rack unit. Up to 64
rack units may be interconnected to create large, unified test systems for multi-channel audio and diverse
testing requirements. Each rack accepts four modules.
Any number of 4021 Input modules may be installed
in a given system. This module provides two high-performance audio inputs, supporting tests over the entire
audio spectrum and a wide range of signal levels. Each
channel operates simultaneously and independently,
doubling effective throughput compared to conventional audio test systems. Multiple modules in a system all operate in parallel, greatly reducing test time
for multi-channel measurements when compared to
switched, repetitive testing.
Two AVERLINK ports (A and B) are supplied on the
back panel. Interconnect racks by connecting A to
B or B to A using the supplied Cat5 cables. (See the
Hardware Installation manual for more information on
interconnections between racks.)

3001 Ethernet Host Adapter
Every system has one (and only one) Ethernet Host
Adapter module. This module provides communication between the system and host computer, and performs test scheduling and results formatting tasks during test execution. Communication with the module is
done via Telnet, and an embedded web server provides
access to configuration settings and status information.
A white front panel LED indicates system activity and
status.
Signal inputs are via balanced XLR connectors. Singleended signals are supported by grounding the cold input (pin 3) to ground (pin 1) and driving the hot input
(pin 2) relative to ground. Ground lift is also selectable
for completely floating balanced inputs.
Currently available native tests are: FFT (32 to 65536
points), Level, DR, SNR, THD+N.

9001 Filler Module
Any number of 4121 Generator modules may be
installed in a given system. This module provides two
high-performance audio outputs, providing audio
stimulus signals over the entire audio spectrum and at
a wide range of signal levels. Each output may be set to
different frequencies and/or levels. Three very low distortion oscillators are available for generating complex
stimulus signals and may be assigned in any combination to either or both outputs.
Rack units require that all four slots be filled with
modules to ensure proper internal communication and
signal integrity. For rack units with fewer than four
modules to meet this requirement each unused slot
is filled with a filler module, which provides needed
signal routing and termination.

3101 Isolated I/O Module
This module provides eight opto-isolated inputs and
eight reed relay SPST outputs. Because the inputs and
outputs are all completely isolated from the system
ground and internal signals, this module is perfect for
controlling processes in noisy environments or adjusting sensitive analog signals internal to test devices.
The eight opto-isolated inputs can be used to sense the
state of external signals, such as proximity switches,
out of limit sensors (overtemp, overvoltage, etc.),
switch closures, test status, and other binary events.
Similarly, the eight reed relay outputs can be used to
close circuits during board-level tests, actuate motors,
valves, or other process control components, light annunciators, etc. These are very high reliability relays;
they are rated at 109 cycles at low signal levels, and can
handle up to 10W.

3102 Digital I/O Module
The 3102 Digital I/O Module is identical to the 3101
module, with the addition of a fully isolated power
supply. This supply can provide power for small external sensors and other test-fixture circuits, and in some
situations may simplify external connections to the
system.
This isolated power supply provides up to 100ma of
current across any of the available 12V, 5V, and 3.3V
outputs. All outputs are short-circuit protected and
current limited. Power is available on both the input
and output connectors.

3103 Digital I/O Module
This module provides eight opto-isolated inputs and 32
digital voltage level outputs, along with a dual bidirectional SPI control port. This module is ideal for control
of external test sets, test devices, and manufacturing
processes.
The opto-isolated inputs are identical to those on the
3102 Isolated I/O module. No power is supplied by this
module to drive external circuitry, other than what is
available directly from the digital outputs.
The outputs are selectable (in 8-bit banks) between
3.3V and 5V logic levels. These are high-current outputs and can source or sink up to 12ma each.
The SPI connector has MISO, MOSI, SCK, and two
CS signals and can support two bidirectional SPI ports
for control and initialization of test devices and/or test
sets. These signals are independent of the 32 digital I/O
outputs and opto-isolated inputs.

6020 Slew Rate Measurement Module
This module performs direct slew-rate measurements
of digital and analog test devices. Its two pairs of inputs
and outputs are fully differential and independent, and
can be used in either differential mode or single-ended
mode, depending on requirements.
When not actively measuring slew rate, this module
passes through all input and output signals to a second
set of outputs and inputs. These can be used to interconnect a 6020 module with a 4021 Input module and
4121 Generator module so that only a single connection to a test device is required to make both analog
audio and slew rate measurements. These signals are
passed through using reed relays, so all connections
are completely galvanic, with no active devices in the
signal path when the 6020 module is not active.
Slew rate is measured by driving the outputs between
any two programmable voltages and measuring the
elapsed time between two programmable threshold
voltages on the inputs. This scheme accommodates
devices exhibiting gain or loss, over a wide range of
possible input and output voltages.
