Hp - agilent 35665A dynamic fft analyzer w/ 5 options
Dynamic Signal Analyzers are instruments which process an input signal to give you various information about the signal (as opposed to an oscilloscope, which simply displays the input signal.) All Signal analyzers have an FFT mode, where they calculate and display the FFT (Fast Fourier Transform, which is an e_cient algorithm for _nding the frequency spectrum of a time domain signal.) This is what the HP3561A (on every lab bench) does. The HP35665A has an additional mode of operation called Swept Sine mode. In swept sine mode, the analyzer outputs a pure sinusoid which it sweeps in frequency. The analyzer then measures the amplitudes of the two input signals, divides them, and plots the result. If the source (the swept sine output) is connected to input #1 (in addition to the input of the circuit under test) and the output of the circuit under test is connected to input #2, then the analyzer e_ectively displays the frequency response of the circuit. The HP35664A is a vector signal analyzer, which means it measures both magnitude and phase, as opposed to a scaler signal analyzer which measures only magnitude. The HP Agilent 35665A, Dynamic Signal Analyzer, that provides measurement solutions in vibration, acoustics, and control systems.
The HP Agilent 35665A, Dynamic Signal Analyzer, options are computed order tracking, real-time octave, swept sine, curve fit and synthesis, arbitrary source, and Instrument BASIC.
