- Filter types:
- Lowpass, highpass, bandpass, bandstop
- IIR filters:
- Choose between Bessel or Butterworth filter type
- Selectable orders: 2nd, 4th 6th 8th or 10th
- Freely definable cut-off frequency
- Supports integration and differentiation
- FIR filters
- Freely definable filter length and selectable window type
- Data decimation for efficient lowpass filtering
- Supports multistage filter design
- Automatic filter delay compensation

CEPSTRAL ANALYSIS
Cepstral analysis in OXYGEN provides advanced tools for audio and acoustic signal processing, ideal for applications like vibration analysis and seismic echo characterization.
- Calculation of amplitude, power, or complex Cepstrum
- Signal visualization in the Quefrency domain
- Liftering signals into low and high Cepstrum

SWEPT SINE ANALYSIS
Our Swept Sine Analysis module is perfect for structural analysis like shaker tests, helping you create Bode diagrams of your device under test.
- Synchronization from 1 Hz to 20 kHz
- Calculate total and fundamental amplitude and phase
- Support for multiple input channels per synchronization source
- Visualize amplitude and phase data in a spectrum analyzer as a Bode diagram

ROSETTE
A strain gauge rosette describes two or more strain gauge sensors that are applied close to each other in dedicated alignments to analyze strain in different directions.
As single strain gauges can only measure strain in one direction, the application of multiple strain gauges provides the possibility of taking multiple measurements and thus being able to assess the strain on the surface being measured more accurately.
- 45°, 60° or 90° rosettes supported
- Freely selectable reference angle
- Wide range of strain and stress parameters calculated automatically
