“We spend 50 percent of development costs on a product after the launch”
5G, IoT, smartphone security and more: Future technology generations pose increasing challenges to the measurement equipment for development and production engineers. Roland Steffen, Head of the Test and Measurement Divison and Executive Vice President of test equipment provider Rohde & Schwarz explains how the company prepares for these challenges.
the most can be identified. That of course goes beyond the boundaries of conventional radiocommunications test equipment.

EETE: Government security agencies are now combating cybercrime. Does this open up new business opportunities for you? For instance, detecting apps that install malware without users knowing it?

Steffen: I don't want to claim that our instruments will tell you that, but they do offer the possibility to view such processes in the first place. There are also unmeasurable aspects that play a role in analyzing measurement results. For example, the question of whether you have a "good" or "bad" server and where it is located. We simulate base stations and allow instruments to connect to the Internet in order to analyze data traffic. A user can assess how little or how much data an app is using and see how actively it is transmitting.

EETE: When designing T&M instruments, there is a visible trend toward moving control and evaluation logic to intelligent devices such as computers. This shrinks physical space requirements to fit in small, very handy and transportable devices. What is your view on this?

Steffen: It is beyond dispute that the computer world has a higher speed of innovation than conventional T&M equipment. Lab test equipment has a lifespan of seven to ten years. A computer lasts two to four. By choosing a solution such as you describe, you can certainly improve the performance and lifespan of a test instrument. That makes sense where speed and automated processes are concerned, such as in production. You can also increase performance by outsourcing certain algorithms to a high-performance computer. We extensively use solutions like these in the production environment. It's a different story in the mobile field. For example, it is of course possible to separate the functions of a battery fed handheld device into a small test module and a tablet. But then technicians would have to carry two devices and
