Agilent 3561A Dynamic Signal Analyzer
Rental
The 3561 A Dynamic Signal Analyzer performs spectral analysis and FFT synthesized 1/3 and 1/1 octave analysis with an 80 dB range. A spectral map as well as time-fixed waveform graphics are displayed in dynamic form, allowing for real-time adjustments. A built-in analog filter (A-weighted) comibined with the 3561A FFT-synthesized octave measurements and sample buffer provide high performance acoustic measurement in the low frequency range (125µHz to 100 kHz).
A tracking generator was also included in this signal analyzer's design for stimulus/response measurements. Agilent 3561A rental takes adavantage of digital processing for extremely narrow bandwidth resolution segments, high resolution, all done very quickly with relatively low sweep times.
