FFT on the Type 2250: Now and Why
To provide a narrowband solution in a timely release. The Type 2250’s High Resolution Touch Screen is ideally suited to
FFT Analysis techniques. Powerful DSP brings tremendous analysis capability
To replace the 2260 FFT application: BZ7208 a moderately successful application. Late/old tech A bit peculiar in some ways (e.g.: frequency spans and line spacing)
To bring vibration measurement capability to the 2250. Real units, including Velocity and Displacement
To give customers a tool for frequency based source identification Environmental, Building Acoustics & Product Noise & Vibration
Applications

2250 FFT offers incredible performance
Up to 6400 Line FFT! Which means…
You cover the complete 0-20KHz audible frequency span with high frequency resolution ~ 3 Hz
Providing the real benefit of simplifying the measurement process.
AND… coupled with zoom analysis you an unprecedented resolution in a hand held analyzer – 1/64 Hz (0.015625Hz)
Providing the real benefit of seeing the details like never before.
You can select from 100 to 6400 lines of analysis in a binary sequence (100, 200, 400, 800, 1600, 3200, 6400)
Because there are lots of times you don’t need all that data!
The Type 2250 FFT lets you pick the transform size to match the job!

Note: 2KHz Span 1600 Line FFT with expanded display
Zooming has never been more fun!
Touch and drag, select zoom and go!– The Type 2250 will automatically select the next wider frequency span.
– Un-zoom by clicking the X axis option

Type 2250 FFT gives you only good vibrations
Finally, an easy to use vibration meter. – The BZ7230 application gives you vibration measurement capability to
any Type 2250 (just add an accelerometer) and display results as Acceleration, Velocity or Displacement – in SI or US/UK units
Total Value, too
