The HP/Agilent 3562A is a dual-channel dynamic signal analyzer delivering time- and frequency-domain measurements from DC to 100 kHz. Built on FFT technology, it combines network analysis, spectrum analysis, waveform capture, transient analysis, and modulation demodulation in a single platform. The instrument achieves 80 dB dynamic range (or over 130 dB with automatic input ranging), ±0.15 dB amplitude accuracy, and ±0.5° phase accuracy. An integrated signal source generates random noise and sine signals up to ±10 Vpeak, making it ideal for characterizing electronics, mechanical systems, and electromechanical control loops without external stimulus equipment.
