Teseq, a developer of instrumentation for EMC emission and immunity testing, has introduced the IOB 4000 input/output box for EUT (equipment-under-test) monitoring during EMC immunity testing.

There are four digital inputs with a voltage range of 0 to 24V, eight low-level TTL outputs, eight TTL inputs, four analogue inputs with a voltage range of 0 to 24V and one optical input.

Up to 12 signals can be monitored with the IOB 4000’s digital inputs, while light sources, such as operating indicator lamps, can be monitored by the optical input.

IO-Test software included with the IOB 4000 allows for all the functions of the box to be tested.

The test software has the ability to test the communications port; set the number of measurements per second; wake up the box; read the serial number and check the battery status.

All inputs and outputs can be seen on the test screen.

When the IOB 4000 is integrated with test house software, data is transferred via the USO 4013 optical interface, which has both RS-232 and USB interface ports.

A 10m fibre-optic cable is included for connecting the IOB 4000 inside a chamber and fibre optically isolated monitoring connections on the input/output box ensure there is no influence of the EUT test on the monitoring computer.

The isolated connections guarantee no influence from outside the test chamber to the EUT while the metal case of the box is optimised for monitoring signals during EMC testing.

Battery power from 4 x 1,2V NiMh rechargeable batteries maintains operation independent of mains power.

On fully charged batteries, the IOB 4000 can operate for approximately one week with eight active hours per day.

In sleep mode, current consumption of the IOB 4000 is approximately 6mA and 26mA during operation.

The IOB 4000 weighs 1.8lb (6.6lb with the storage case) and measures 6.30 (l) x 4.45 (w) x 2.36in (h), while the storage case measures 17.72 (l) x 14.17 (w) x 5.32in (h).

Pricing starts at USD2,990 (GBP1,808), for the complete system.

Teseq — EMC test solutions: combining tradition and experience with dynamic and innovative development 

Teseq is the new name of the Test Systems Division that belonged to the Swiss-based Schaffner Group until it became an independent company after a management buyout in 2006.  

Teseq has retained all of the former Schaffner Division’s management and employees ensuring business continuity, commitment to existing and new customers and a dynamic approach to new product development.  

Teseq also continues to stand for customised client support, proven products and extensive know-how. The company’s focus on its core business — EMC test solutions — will be reinforced by greater attention to innovation in the area of research and development. The streamlined size of the enterprise ensures maximum independence, agility and flexibility.  

Teseq offers standalone products and complete solutions for EMC conducted immunity testing including: ESD generators; harmonics; flicker and power quality test systems. It also provides a complete range of EMC radio frequency test equipment from measuring receivers, power amplifiers and GTEM cells to very powerful software for the automation of EMC test houses.    

Teseq’s extensive knowledge of EMC systems can be found in more than 90 countries worldwide with hundreds of systems installed in applications such as automotive, military, telecoms, commercial and medical.
