Post Processing

Powerful analysis after measurement

Acquiring different signals (analog, digital, counter, CAN, video etc.) simultaneously from different sources with different sampling rates and storing them in one file allows comprehensive, not yet experienced analysis for all type of applications.

Power Analysis

Different wiring schematics allow the power calculation for all possible connections. These are single phase, star connection, delta connection, V connection, Aron connection and a combined star / delta connection. All with or without currents. It’s even possible to analyse 6-, 7-, 9- or 12-phase motors due to the combination of powerful hardware and software.

Power calculation

  • P, Q, S, D
  • Cos Φ, power factor
  • P, Q, cos Φ for each harmonic

Star - delta calculation

  • It is possible to calculate out of a delta connection all values and the waveform for the star connection and vice versa.
  • Waveform: U1, U2, U3 < > U12, U23, U31

Multiple power calculations

It is possible to do a number of power analysis within just one device. For example with the SIRIUS R8D you can measure 8 three phase systems completely synchronous. Furthermore it is possible to do the analysis for different frequencies (DC, 50Hz, variable frequency etc.) and wiring schematics (1 phase, 3 phase etc.). Any additional mechanical values like torque, speed, noise, temperature and vibration can be captured and synchronously analysed.

Typical configurations

  • Motor & Inverter Measurement
    3x 3-phase AC power (var. frequency)
  • E-Mobility
    4x 3-phase AC power (var. frequency) 6x DC power
  • Aircraft

    1x 1-phase AC power (50 Hz)
    5x DC power
  • Marine
    7x 3-phase AC power (50 Hz)
    4x 1-phase AC power (50 Hz)
    1x DC power
  • Railway
    1x 3-phase AC power (50 Hz)
    3x 1-phase AC power (16.7 Hz )
    3x DC power

Frequency Calculation

The software PLL guarantees a very accurate frequency calculation (mHz). On one system multiple power systems can be measured and each can have its own frequency. With the use of the different instruments from DEWESoft® the values can be shown in several ways.

Possible line frequencies:
16.7 Hz: Railway Sector, 50 Hz: Public Grid, 60 Hz: Public Grid, 400 Hz: Aerospace, 800 Hz: Aerospace, Variable frequency: Inverter (from 0.5 Hz to 3 kHz).

Frequency Source

In Dewesoft X software you can choose whether you use the voltage, current or an external source as frequency source. This is a very helpful feature especially at inverter measurements. Due to the PWM modulated voltage signal the correct period time often can not be determined right. The current is much less distorted because of the high inductance of the motor coil. Therefore it’s to often better to use the current as frequency source at inverter measurements. This feature ensures correct frequency determination for every application.

Raw Data Storing

With a very specific data file structure we can write the channel setup, display setup, all the events, fast analog data and slow asynchronous data from different sources in a single file. For long term measurement Dewesoft X offers to roll-over the file automatically when certain file size is reached or after a specified time (for example after 24 hours the current file is closed and a new one is created automatically). Dewesoft X makes sure that no data is lost during the file roll-over.

Calibration Accuracy

Voltage and Current transducers always have a frequency dependent amplitude error and phase shift. With Dewesoft X unique software calibration technology amplitude and phase can be corrected for the full frequency range from DC up to 1 MHz. All internal curves like filter response are corrected inside the software and the sensor database includes correction curves for each clamp, rogowsky coil, transformer or which sensor ever is used.

Fault Recorder & Transient Recorder

  • Trigger on all channels possible (analog, digital, power, math, etc.)
  • Setting a trigger on all parameters of the power module!
  • U, I, P, Q, S, D, cos Φ, power factor, ...
  • Pos-, neg-, zero-sequence systems
  • Very fast glitch detection (up to MS/s)
  • Math. channels (rpm, torque, efficiency,...)

We can also use math formulas to create combined trigger conditions. When the trigger event happens, data is stored with the fast sampling rate (with pre- and post-time) while otherwise only reduced data (min, max, average, RMS) is stored. This reduces the file size in long-term measurements.

Math Library

Even though the main focus of Dewesoft X is on data acquisition and storage, it also offers powerful analysis features. The powerful math library covers functions which makes data analysis directly in Dewesoft X and even possible during measurement.

Imagine having a big data file of a long-term battery test. With the formula mathematics you can define logical conditions (e.g. if current > 10A AND temperature > 70°C) to quickly find the positions you are interested in. It’s also possible to exclude faulty data points, such as spikes, just by defining logical conditions.

Furthermore, often used functions like delta time measurement between two signal edges, counting how often conditions appear, or holding the signal value on a condition and many more are already prepared. Use the complex section to split a signal into real and imaginary part, while the array section is used e.g. to cut arrays or determine min/max and their positions.

Math Features

  • Filtering (FIR, IIR, FFT filter, integration, derivation, ...)
  • Logical conditions

  • Envelope function
  • Delay channel (previous value, delta-calculation)
  • Latching (hold value on certain condition)
  • Angle sensor math (convert analog input signal from tacho probe to freq. + angle)
  • Scope trigger
  • Spectral Analysis (FFT, STFT, CPB, SineProcessing)

Analyse & Publish

Post Processing

Post processing is a unique feature of Dewesoft X which allows to do all analysis and mathematics after the measurement for already stored data. It’s even possible to change measurement settings. Post processing the data files is possible on any computer, without any license.

File Preview

One of the most outstanding features of Dewesoft X is that data files, even if they are several gigabytes in size, are loaded in a matter of seconds. A special data structure allows fast reloads and zooming. You can select any part of the data in the recorder and zoom in to show all the interesting details.

Grand View

Enhanced freeze mode (Grand View) allows user to review stored data from start of measurement without interrupting data acquisition and storing process. User is able to zoom into any region of data already stored on disk during the measurement and review any type of signal including video, which makes (long term) measurements easier to manage.


To get an impression how the measurement was done, especially when we have video streams in the measured file, Dewesoft X offers file replay capabilities. We can choose a specific portion in the file and replay the data with the same speed as it was stored or with higher/lower speed. Dewesoft X does not only show the data, but it can also replay the data through sound card. Dewesoft X can also replay data of any channels through SIRIUS AO8.

Data Export

Dewesoft X has extensive support for exporting the data to other file formats for further post processing. You can choose different export file types, use scripting for direct reporting and export raw, reduced or angle based data. Dewesoft X offers templates with Flexpro, MS Excel® and Famos. These templates allow you to prepare the reports once and execute them after data export. In this way you can automate report generation and simplify the measurement process. Alternatively you can export your measurement screen to video file. This allows to replay the file with every standard video player without the need of installing Dewesoft X.

See publish & export for full list of supported export formats.


When you are reviewing data in the analyze mode, you can make hard copies as easily as clicking the Print button in the top toolbar. Any display can be directly printed to PDF or printer. Even the channel setup can be printed for documentation purposes.


If you need to acquire data from additional interfaces Dewesoft X the right tool for you. Additionally to standard analog inputs you can easily acquire data from additional interfaces like:

Video (DirectX, High-speed, Thermal)
Vehicle bus interfaces (CAN, OBDII on CAN, J1939 and J1587, XCP)
Counter inputs
Aerospace interfaces (PCM, Chapter 10, ARINC 429, MIL-STD-1553)

Data is fully synchronised from all sources. For full list of supported interfaces please see DEWESoft X inputs section.

Database Storing

The Online Data Export (ODE) plugin can export measurement data during acquisition directly to a database or to .csv files (that can later be imported into the database).

The ODE plugin is well suited for real-time monitoring of substations, power plants, industries, etc. Beside the RMS values for voltage and current also all power quality parameters like harmonics, THD, flicker, unbalance etc. can be stored in the database.

The transient recording functionality allows to store the analogue signal of voltage and current at extraordinary system conditions (over- and under voltage, frequency deviations, etc.).

The ODE plugin will store the measurement into the database. The customer may use any visualisation or analysis tool that can access the data in the database. Dewesoft X does not offer any visualisation or analysis features or programs. Also database related tasks like installation and maintenance are not provided and supported by Dewesoft X.

Supported Database Systems
Currently the ODE plugin supports MySQL® and Microsoft SQL Server® databases. Other databases (e.g. Oracle®, PostgreSQL®, ...) can also be supported on customer demand (please ask our sales department for a quotation).

Network Acquisition

With the Dewesoft X NET option your measurement system can be controlled remotely with ease of use you couldn’t imagine before. OPT-NET also serves as the centre of Distributed Data Acquisition systems where you have multiple systems located either together or scattered across an entire continent.

IRIG and GPS time will take care that data will stay synchronised, no matter how long the acquisition runs. OPTNET offers three basic modes of operation (1:1 mode, x:1 mode, 1:x mode). With these three modes almost any application can be covered. From single channel expansions over remote control to distributed measurements over hundreds of kilometres - everything is possible.

Special power related courses

Current measurement

The electric current is a physical quantity caused by voltage and means a flow of electrons between different electric potential. An electric current is the flow of the electric charge.

View course Take quiz

Voltage measurement

Electricity is very hard to imagine because we can not see if a voltage is present or if a current is flowing. If we want water to flow out of a pipe we need some water pressure which is achieved with a water pump. In electricity, our flow is the current, water pressure is the voltage and pump is the battery. This means that the voltage is the cause of the current.

Power analysis

Power is the rate of doing work. It is equivalent to an amount of energy consumed per unit of time. The power of an electrical system is the multiplication of the voltage with the current, integrated over and then divided through the periodic time. We have to know the periodic time (equals frequency) to calculate the power of an electrical system.
