Keysight 3582A Spectrum Analyzer 0.02 Hz - 25.5 kHz

Agilent/Keysight 3582A offers outstanding value in a dual-channel, real-time spectrum analyzer that solves bench and systems measurement problems in the frequency range of 0.02 Hz to 25.599 kHz. Sophisticated LSI digital filtering combined with microcomputer execution of the Fast Fourier Transform (FFT) provides exceptional measurement capability and performance.

Unlike conventional dynamic signal analysis which extends from dc to some maximum frequency, the 3582A can ""zoom in"" to analyze any selected band of frequencies with dramatically improved resolution. The start or center frequency of the 5 Hz to 25 kHz band analysis spans can be adjusted in 1 Hz increments to cover the entire frequency range of the instrument. This provides resolution, representing as much as a 5000 to 1 improvement over conventional ""baseband"" analysis. With frequency ranges from 25 kHz down to 1 Hz full scale, the 3582A is extremely well suited to audio and sub-audio measurements.
