E# products for common test- & measurement challenges

Our products are the solution to your measurement problem.

Often, we develop a specific module or even a specific form factor to your needs. But we also have standard modules for a wide range of measurement applications.

AGENT our products


Agent stands for Accordion Generic Test Interface.

AGENT™ is a versatile test- and automation platform for a wide range of applications, including test interface, automated machine control systems and data logger. The base unit provides I2C, JTAG, SPI and UART communication as well as 32 channel Fixture control I/Os and fan control. Modules can be added to expand capacity up to 192 measurement channels through the on-board IDC connectors. Additional expansion slots are also available. Real linux-based computer system offers modern connectivity and a wide range of possible on-board functionality. 

The Accordion™ build system offer a wide range of different modules that allow you to customize your test solution or be plugged into your AGENT™ system directly. 
Modules commonly used by our customers are described below. We are happy to design custom modules together with our customers, depending on their requirements. 

Software modules are additional functionality that can be loaded into the Accordion framework and act as any other (hardware) module in the system. This can be very useful, as new peripheral features and functionalities can be integrated into the same software/driver structure.

MPIO Module

MPIO 64 channels

64 channel multi-purpose input output module. Each channel can be individually configured to be either analog input/output or digital input/output. It can also measure resistance on channels 1-56.


Based on dual ATMEGA microprocessors, it provides 64 configurable channels (up to 32 channels can be configured as analog inputs). Can be used for specialized functions or used as a GPIO/MPIO expander.

Dual ATMEGA 4809 microprocessors

64 channels – up to 32 can be configured as analog inputs

Can implement specific functions or bus protocols

8-bit ADC

Analog multiplexer module

Analog Multiplexer Module

10*8 Multiplexer configurable as 1:80, 2:40 …10*8. Lanes A-B, C-D … J-K are length matched. Option to route Accordion’s SPI, I2C and UART buses to all channels.

MPIO Module

MPIO Module

64 channel multi-purpose input output module. Each channel can be individually configured to be either analog input/output or digital input/output. It can also measure resistance on channels 1-56.

PSU module

Dual-channel, 2-quadrant power supply module with voltage/current measurements and sense.

When you need to source or sink current. For example when testing batteries.

VOUT module

VOUT Module

24 Channel linear power supply that operates in 2-quadrants (able to both sink and source current).

VBUS power switch

The USB Power Switch for AGENT™ is a 4-channel power switch that support pass-through of USB2.0 and USB3.0 data as well as switchable VBUS capability. The USB Power Switch is mainly used in a manufacturing environment. Without it you encounter problems such as Short circuit in the computer usb port? You will have to restart the computer Your product is in need of high current? Limited number of parallel tests With the USB Power Switch this is possible. You can also measure the current voltage and turn each channel on and off individually.


Harmonix™ is an all-in-one test fixture made to be customized for your needs. It’s designed with modularity in mind, allowing every system to be configured for the intended use case. 

There are fives variants of the Harmonix™ fixture ranking from smallest to largest in size; Tiny, Compact, Space, Grande and Ultra. The Harmonix build system offer a wide range of different modules that allow us to accommodate your needs.    

If by chance your needs are outside of what are modules are designed for, we have a team of designers that will create custom parts for your system. The Harmonix™ system is easily integrated with the Accordion™ test system allowing for a seamless and easy test solution.  

Each Harmonix™ fixture is kitted with general I/O, a powerful pc capable of running test sequences at a high speed, AC/DC converter for either 12V or 24V. The rest depends on the application, thus giving you a system that only has what you need, and nothing is redundant.

Harmonix™ Compact

Experience tailored testing with the Harmonix™ Compact, the versatile mid-sized model in our range of test fixtures. With a usable area of 150 x 240 mm, the Compact is perfectly sized to test a good range of products while maintaining a sleek footprint. This model can, as all our models, be equipped with custom testhardware. 

Harmonix™ Grande

Meet the Harmonix™ Grande, the expansive choice in our lineup of modular test fixtures. Featuring a generous usable area of 540 x 310 mm, the Grande is designed to house your products in need of more testing area and has lots of customizable space inside when it comes to hardware equipment.
