LTTpro - The professional measurement data acquisition software

LTTpro is the standard control and display software which, from version 4.0, offers numerous improvements to the user interface as well as an online math function. The professional measurement software helps you to record, analyse and visualize your measurement data.

The incoming data can be analyzed and the results displayed in real time while a measurement is still in progress. A wide range of mathematical functions such as Fast Fourier Transformation (FFT), averaging, histogram etc. can be applied directly to the measurement data or to results that have already been calculated. This makes it possible, for example, to smooth the course of an FFT over a longer period of time.

Thanks to a patented solution, no driver is required. This makes it easy to set up the measurement software. Plug in the device, connect the sensors: measurement data is immediately visible, recorded in real time in analog and digital form and saved directly in a variety of common file formats such as FAMOS, DASYLab, Diadem, MATLAB, Excel (...and many more).

NEW: With LTTpro you get the flood of data under control

Our data acquisition software for the analysis and visualization of the measurement data has been extended by a very important function. So far, continuous measurements with high sampling rates generate huge amounts of data. In order to get these under control, LTTpro has equipped an additional algorithm that allows you to conveniently process your inspection tasks in the highest quality and bandwidth without losing important information and without flooding your data archive.

Software-Option: LTTpro Power Analyzer

The "LTTpro Power Analyzer" software option specially developed for the LTTsmart offers high-performance electrical power measurement that is perfectly designed for modern electric drives at varying speeds. The LTTsmart uses highly optimized algorithms to determine and display the exact rotation cycles even from very noisy phase current sine curves. In addition to all the usual power characteristics (RMS values, reactive/apparent/active power, power factors, speed, efficiency, etc.), the distortion (THD = total harmonic distortion) of all phase currents and voltages is also continuously determined and displayed. Calculations on a half-cycle basis and averaging over several cycles are also possible.

The parallel display of raw data and calculated Power Analyzer data immediately reveals the causes behind any anomalies in the key performance indicators.

At the push of a button or via configurable trigger events, entire raw data time windows can be saved together with the associated calculated Power Analyzer key figures with turn-by-turn accuracy, while the continuous power calculation simply continues to run.

The compact LTTsmart systems can not only be operated in the test bench but also conveniently in the vehicle itself. In addition, the software can also display, analyze and forward previously recorded or emulated data, so that all requirements relating to driving cycles, vehicle testing, production monitoring, development and optimization are covered.

The LTT hardware and software package therefore offers an efficient solution for measuring the performance of an electric motor in the test field and in real use.

LTT library for connection to DASYLab, Gantner (GI.bench), Matlab, Stiegele (µLab), LabView, etc.

Incoming data can be analyzed during a running measurement and the results are displayed in real time. Various mathematics functions such as the Fast Fourier Transformation (FFT), averaging, histograms etc. can be applied directly to the measuring data or to already calculated results. This makes it possible, for example, to smoothen the curve of an FFT over a longer period of time.

Online Mathematics Function

The display of the online mathematics is independent of the input signal display, and can be manipulated as desired without changing the view of the analog data. With the help of several cursor markers, defined individual values of the online mathematics can be shown directly in the display or as an overview of for all channels in the channel view.

Benefit from digital filters, power analysis, EMC investigations and the brand new pulse maths.

When purchasing a new device, the LTT24 and LTTsmart come with LTTpro (without online mathematics) to record and process data.

A license needs to be purchased for the online mathematics module. The basic version includes the most important functions such as integral FFT, FFT (10 different window functions, normalization and spectrum type can be selected), histograms, RMS and smoothing (mean value). Due to the highly modular structure of the online mathematics in LTTpro, customers can adapt it to their individual needs.

Online mathematics is now available for all versions of LTTpro 4 and is activated by importing the required license.

You can purchase the required license for your software and the online mathematics function from us. We will be happy to provide you with an individual quotation.

In cooperation with our software partners the LTT24 and the LTTsmart offers additional software-options:


DASYLab® von measX – measuring, controlling, regulating
