CF-7200 Portable FFT Analyzer
Noise analysis procedure
To perform noise analysis by using the AC out terminal of the sound level meter, operate unit calibration to enable reading
the same unit as the sound level meter. This document describes the simple calibration method using the CAL signal [1
kHz, 94dB] from the sound level meter. This document also describes the simple method of power spectrum averaging
measurement, octave display, and 3D display. The unit calibration in this document, the analog output of the sound level
meter is connected to the CH1 of the CF-7200 and the level range is selected as 100 dB.
Throughout this document, the name of any soft key on the screen will be presented in square brackets (e.g., [MAIN]), and
the name of any operation button on the panel will be enclosed by single quotation marks (e.g., 'START'). In the text, "key"
means a soft key on the screen and "button" means an operation button on the panel.
