DewesoftX offers powerful signal processing capabilities used for automotive, aerospace, power & energy analysis, NVH, and structural dynamics applications in a single software package.
Dewesoft X data acquisition software package offers easy to use and extensive mathematics library for signal processing and analysis. All Mathematics can be applied online in real-time during the measurement itself or later in post-processing (offline).
Dewesoft X will always store raw data from the connected sources. All math applied to these sources will result in additional "virtual" math channels. Original raw data will always stay intact.
This allows existing and new math to be changed and applied later in analyze/offline mode easily for post processing. No more worries if you forgot to apply or your math was wrong during measurement. Now you always have the capability to change it at any time.
The math library inside Dewsoft X offers unlimited signal processing capabilities but makes common processing techniques just one click away. Math library functionalities are offered out of the box:
You can learn more in the math library online manual and Signal Processing online PRO training course.

Filters are grouped into three filter modules:
Classical electrical filters like Chebyshev, Butterworth, and Bessel can be applied using the IIR filter module. These filters also allow single and double differentiation and integration.
When signals are filtered using standard FIR filter it introduces a phase shift. The output signal is delayed compared with an input signal. Dewesoft FIR filter is smarter and filters data without any phase shift or delay. This is perfect and can be used also for the analysis of signals which does not allow having phase shifting or delay.
The frequency-domain filter performs an FFT calculation and cuts a certain range of signals to create the sharpest possible filtering.
To learn more about Filtering please visit the Filtering section of the Dewesoft X online manual and Signal filtering online PRO training course.
The basic statistics module provides basic statistical quantities of the signal:
There are five basic calculation modes. Block-based, Running, Single value, Triggered blocks, and Start-stop blocks. The statistical function is selected as an output channel.

The order tracking module makes it extremely easy to take time-domain data and transform it into the angular (order) domain. It can extract any number of harmonics (amplitude and phase angles) which can be displayed in Bode, Nyquist, 3D FFT, real-time x-y, and orbit plot. The plane view FFT clearly shows the excitation forces, natural frequencies, and all the resonances to give a clear picture of the dynamic behavior of the machine.
Any input can be used: microphone, accelerometer, and even the output of the torsional vibration module (see below). The patented digital counters technology (Supercounter®) provides very accurate and repeatable measurements.

The module offers an extremely straightforward and easy analysis of torsional vibration for rotating shafts, gearboxes, and similar rotating machinery.
High precision digital counter inputs on our DAQ systems with the patented technology called Supercounter®, based on a 102.4 MHz time base, allows for exact measurement and calculation of rotational and torsional vibration angles and velocities at high RPM speeds from two encoders mounted on each side of the shafts. The difference between the rotations of each side is the torsion twist of the measured shaft.
Constant angle offset, uncentered mounting, and sensor errors can be compensated. Gearbox ratios are supported and additional filters can be applied. Several torsional vibration modules can be combined to analyze torsional vibration on complicated transmissions.
