The 3561A is a low frequency, high performance dual channel dynamic signal analyzer. Displays include a three-dimensional spectral map and time waveforms. The 3561A incorporates a 40 k sample time buffer for later measurements and allows for acoustic measurements with its FFT-synthesized 1/3 and 1/2 octave measurements, together with the built-in analog A-weighted filter.
The analyzer also has a built-in tracking generator for stimulus-response measurements . With built-in waveform math, magnitude and phase measurements are possible. Digital processing is used to provide ultra-narrow resolution bandwidths up to 640uHz. Digital processing also speeds up measurements; a measurement with 1 Hz resolution requires only a 1.5 second sweep.
In addition to spectrum measurements, the 3561A displays time waveforms similar to oscilloscope displays. A 40k sample time buffer captures transients for examination in the time domain or analysis in the frequency domain. The HP 3561A is also an excellent analyzer for acoustic testing.
