FFT & CPB Analysis
Type 7700 is PULSE’s base software for FFT, CPB (1/n-octave) and Overall analysis with simultaneous measurement of exponential, linear, impulse and peak levels.
Type 7700 provides general noise and vibration testing using real-time, multichannel analysis as well as general R&D, noise and vibration analysis using several analyzers and multiple frequency spans simultaneously.
With user-definable measurement solutions, all your basic requirements, including data acquisition, measurement, analysis, calibration, post-analysis and reporting are convenient and manageable.
Powerful Analysis Capabilities
- Real-time measurements on 200+ channels
- Multi-analysis allows multiple analyses of the same input data, reduces test and reporting time, and ensures consistency of data, for example:
– Simultaneous FFT and 1/n-octave analysis of the same data
– Simultaneous analysis using several FFT analyzers with different properties such as frequency span, zoom, etc.
- Real-time signal analysis using the PC’s CPU. The standard package includes 75 PULSE beats, enough real-time DSP resources to perform:
– FFT analysis on 16 channels to 25.6 kHz bandwidth (0% overlap, 6400 lines)
– 1/3-octave analysis on 6 channels to 25.6 kHz bandwidth
- Powerful signal generator, providing a host of sine, random and user-definable waveforms (requires hardware module with generator support, see BU 0228)
- Tonality and prominence ratio calculations according to ECMA74 and ISO7779
- Reverberation time calculation
Easy-to-use Software
- Running on Microsoft® Windows® 2000, Windows® XP, and Windows® Vista operating systems, Types 7700/7770/7771 are the basis for an ever-increasing number of sound and vibration applications
- Easy first time setup through the use of dedicated, intelligent taskes
- Task-oriented user interface that guides a user through the measurement process step by step. Task views are easy to set up and customise for specific needs. They are the best way to switch easily between multiple display and settings windows
- Display manager eases management of displays and signals
- Data export in a variety of formats for use with external applications
- Linked with Microsoft® Word and Excel allowing fast, automatic report generation and post-processing
- Built-in VBA (Visual Basic® for Applications) allowing easy customisation of PULSE
- A comprehensive library of sample projects and technical literature
- IRIG-B time/data synchronization – ensures timestamp alignment between different types of IRIG-B enabled instrumentation using an encoded analogue channel
Auxiliary Parameter Logging
Measurement of auxiliary, pseudo-DC parameters with 12 channels of low-frequency (10Hz
sample rate) input channels that can be recorded along with the dynamic channels and used as logging or multi-buffer tags (available via LAN controller modules, see BU 0228).
