HP 3569A Hand-held Realtime Dual-Channel Dynamic Signal Analyzer

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 conditioning is not required. Built in pink and white noise sources provide a convenient source for reverberation time and stimulus/response measurement.

Documentation and Analysis
The HP 3569A measurements can be printed on HP DeskJet or HP LaserJet printers, or HP-GL plotters via RS-232. Stored data can also be transferred to a computer via RS-232 and is compatible with Hewlett-Packard's SDF (Standard Data Format) which allows data transportability to other Hewlett-Packard dynamic signal analyzers and third-party analysis packages. An optional utilities package (Opt 550) simplifies data transfer to PCs; it includes special tools for programming and for use with the HP 95LX palmtop PC.
