Portable FFT Analyzer
CF-3200/CF-3400 |
|
|
Compact & High Quality
|
The CF-3200/CF-3400 portable FFT analyzer provides on-site
precision measurement and analysis of sound and vibration that is both efficient
and hassle-free.
Its compact and lightweight attachér""""-case form makes it easy to transport
to and around the site. Such features as the battery/AC-powered operation
and built-in sensor amplifiers, mean that there are virtually no limitations
on the location for analysis.
There is also a wide choice of application software available for the analyzer,
which support a variety of measurement tasks. These include tracking analysis
to evaluate the dynamic characteristics of rotary machines and engines,
measurement of natural frequencies using frequency-response functions, precision
diagnosis and field balancing of factory equipment, and real-time octave
analysis that has proved very effective in sound analysis. |
