The Keysight 3588A is a spectrum analyzer for signal characterization across DC to 150 MHz. It delivers noise-floor sensitivity of −145 dBm typical and dynamic range exceeding 70 dB, making it suitable for precision spectral measurements in R&D, design validation, and manufacturing test. The instrument combines selectable resolution bandwidth (0.1 Hz to 1 MHz), variable video bandwidth filtering, and FFT-based analysis with marker peak search and trace operations including max/min hold and arithmetic functions.
