Information
The Type
1564-A Sound and Vibration
Analyzer, Figure 1-1,is
a portable instrument for the frequency analysis of voltages
having components between 2.5 cps and 25 kc. The high input
impedance of the
Analyzer permits the direct connection of
piezoelectric transducers for the analysis of high- level
acoustical spectra. For low levels, the
Analyzer can be
operated in conjunction with a sound-level meter or a
vibration meter. Designed for either manual or automatic
tuning, the
Analyzer can be used with a graphic level
recorder, such as the General Radio Type 1521, to produce
continuous plots of level as a function of frequency.
