Agilent Technologies, Inc. 35665A 2-Channel DC to 102.4 kHz
Feature:
Minimum Frequency: 0Hz
Maximum Frequency: 102.4kHz
The HP 3569A is a portable, battery-powered real-time frequency analyzer designed for onsite product-noise characterization,
including real time sound intensity analysis. Octave and 1/3-octave resolution measurements are made in real time. For tonal
measurements of single frequencies or narrowband signals, the optional FFT mode provides from 100 to 1600 lines of linear
frequency resolution for high accuracy.
The sound-intensity mode in the HP 3569A can be used to identify noise sources or measure sound power. Individual surface
areas are entered into a sound-power measurement table and sound-power is automatically calculated at the end of the
measurement. Sound-intensity probes are directly compatible.
Reverberation time analysis can be added as an option. An Integrated Electronics Piezo Electric (IEPE) and microphone input
mode can directly power accelerometers (with a 4 mA constant currant supply) and microphones so external signal
