The HP 3561A is capable of spectrum and network analysis, waveform recording, and 1/3 and 1/1 octave analysis.
It also features a high accuracy of ±0.15 dB, 80 dB dynamic range and full alias protection, and band selectable zoom analysis for 640 µHz resolution.
Incorporates internal non-volatile memory which will store 2 traces and 6 states.
Other Info:
The Agilent HP 3561A is a low frequency, high performance dual channel dynamic signal analyzer. The 3561A displays include a three-dimensional spectral map and time waveforms.
The Agilent HP 3561A incorporates a 40K 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 HP 3561A 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 640 µHz. 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 Agilent HP 3561A displays time waveforms similar to oscilloscope displays. A 40 K 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. The HP Agilent 3561A is a versatile, single channel, real time spectrum analyzer with applications in electronics, vibration analysis, and acoustics
