NF’s frequency response analyzers utilize the excellent noise eliminating feature of Fourier transformations to accurately measure frequency response characteristics. Equipped with floating input circuitry and auto ranging functions for constantly optimizing input ranges, our FRAs allow dynamically changing frequency responses to be quickly measured with high accuracy, without the need to be concerned with input signal levels or the ground potential of the device being tested; moreover, operation is quite simple.

From ultra low frequency to high frequency.
High density measurements of up to 20,000 points at one sweep are possible.
Logarithmic equal interval setting and auto-magnification in sections where values greatly change are possible. Resolution is 0.1mHz.

FRA5087 : 0.1mH to 10MHz Higher than the conventional 2.2MHz model!
FRA5097 : 0.1mH to 15MHz

Amplitude accuracy : ±0.05 dB , Phase accuracy : ±0.3°
Digital Fourier transforms and a self calibration function assure that measurements will always be highly accurate.

Auto ranging which optimizes the measurement range at every measurement point and a high resolution A/D converter secure a wider dynamic range. Measurement is secured if a great change occurs during measurement.
Input range is switched automatically according to the input signal level, so setup of voltage sensitivity is not necessary for the frequency response analyzer.

Measuring conditions can be set via an external personal computer and measured data can be read out to it via GPIB and USB.
Measured data can be stored and loaded into a USB memory device. Furthermore, the following functions are available.
A screen can be output to the USB memory and printer by the press of a key.
Setup conditions can be saved into and loaded from the USB memory by the press of a key.
Data stored in the USB memory can be read out to a personal computer for graphic display and saving in a CSV format.

"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."

“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.”
