Analyzer Type
2147 are portable FFT analyzers for
acoustics, electroacoustics and vibration measurements.
Their light weight and water-protected cabinets make them
especially well suited for use in the field, yet their
measuring capabilities easily match those of a laboratory
instrument. The analyzers feature 2048 sample transform size
(801 lines), real-time zoom, advanced cursor functions, and
a frequency range to 25.6 kHz in single-and (for Type(
2148)
dual-channel operation.
The analyzers are operated by means of user-interactive
menus. This enables you to quickly become familiar with the
use of the
Analyzer. Access to a system of on-screen help
pages provides you with information about the use of the
menus at any time and in any place.
A large internal non-volatile memory, together with back-up
disk storage facilities, make the
Analyzer a powerful
data-gathering device. The IEEE 488 and RS-232-C interfaces
allow data-processing and external control.
