The frequency response analyzer (FRA) is a high-precision instrument that is applied to analyze components, circuits, and systems (abbreviated as DUT: Devices Under Test) in the frequency domain. Usually, the FRA generates a sinusoidal signal for this purpose, which is applied to the DUT. This signal is measured both at the DUT’s input and output. In order to determine the DUT’s response over a wider frequency range, a ‘sweep’ is executed with which the sinusoidal signal runs through a user-defined frequency range.

This instrument is just as important to a hardware engineer as, for example, an oscilloscope, as this precision-instrument can determine the transfer characteristics, (resonance) response of input, RF, and EMC filters, transistors, voltage regulators, signal transformers, cables, and measurement and control systems, such as servo motor controls, the AC impedance of fuel cells, and many other DUTs.

TTMS offers NF Corp. and Newtons4th frequency response analyzers.

WHAT OUR CUSTOMERS SAY

Arnold Memelink

ABB

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

Sasan Rafii-Tabrizi

University of Luxembourg

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
