Rohde & Schwarz introduces EMI test software at EMV 2017

At EMV 2017, in Stuttgart from March 28 to 30, 2017, Rhode & Schwarz will demonstrate its Elektra EMI (electromagnetic interference) test software for EMI measurements during product development. It supports EMI test receivers and spectrum analysers from Rohde & Schwarz. The company says it is easy and intuitive, even development engineers or technicians who only occasionally use these instruments to measure EMI are able to configure automated test sequences quickly, often right in the development lab, using GHz transverse electromagnetic (GTEM) cells or line impedance stabilisation networks (LISN).

Manufacturers of electrical and electronic modules, components, devices and systems must perform electromagnetic compatibility (EMC) tests to ensure that products will not interfere with other components or devices. Many manufacturers perform EMI pre-compliance tests during development to make sure products will pass the final acceptance tests.

The Elektra EMI test software measures EMI. The software is designed for use with EMI test receivers and spectrum analysers from Rohde & Schwarz, and it supports both interactive and automated test sequences for commercial products and military applications.

The Elektra EMI software performs a preview measurement based on pre-defined test templates to measure the device under test’s (DUTˈs) frequency spectrum. The result is compared against appropriate limit lines. Time-consuming measurements with a standard-compliant detector will be performed only if limits are violated.

The Elektra EMI test software does not only provide the limit lines for the various test standards, together with the antenna factors, it also delivers conclusive measurements in the development lab, says the company. For example, development engineers can use an LISN when measuring conducted disturbance. With smaller, battery-operated DUTs, a GTEM cell can be used. In this case, the Elektra EMI test software processes the measured values to generate results that are comparable to those that would be obtained during an open-site measurement with an antenna.

A dashboard on the user interface provides quick access to settings, tests, test templates, and other functions. Frequently used elements can be added to the dashboard as favourites. The Elektra EMI software saves each test configuration with a block diagram, allowing users to quickly access individual parameters by clicking on the associated components.

The software acquires measurement values and documents results together with the test configuration and all instrument settings. Users can add descriptive text and images. Reports can be generated and exported in CSV, Excel and PDF formats.
