Informations

Dual Channel Portable Signal Analyzer Type 2148 and Portable Signal 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.
