The Agilent/Keysight 3588A is a high-performance spectrum analyzer for frequency-domain analysis spanning 10 Hz to 150 MHz. It delivers precise spectral measurements, scalar network analysis, and signal characterization through dual operating modes: traditional swept spectrum analysis and fast FFT-based narrowband zoom. The instrument combines amplitude accuracy better than ±0.4 dB with dynamic range up to 112 dB, making it suitable for audio equipment testing, telecommunications, and signal monitoring applications.
