The HP 35670A is a versatile FFT analyzer with built in source for general spectrum and network analysis, and for octave, order, and correlation analysis. Rugged and portable, it is ideal for field work, yet it has the performance and functionality required for demanding R&D applications. Built in source with optional analysis features optimize the instrument for analyzing and troubleshooting noise, vibration and acoustic problems, evaluating and solving rotating machinery problems, and characterizing control systems parameters.
