The SA-78 is a portable, powerful and sophisticated dual channel frequency analyser. FFT analysis (up to 1600 lines), the waveforms, transfer function between the two channels and coherence of the two channels can all be measured in situ with this small, battery-powered instrument. The dual channel BNC input makes it suitable for general signal analysis but it is particularly well suited to sound and vibration analysis (CCLD accelerometers are supported). With the waveform recording option installed the instrument can also store a 1 or 2 channel calibrated wav file.
