The Agilent/Keysight 1663AS is a benchtop logic analyzer with integrated 2-channel oscilloscope capabilities, delivering simultaneous state and timing analysis for complex digital system validation. This dual-function instrument captures non-repeating events across 34 logic channels and 2 scope channels, supporting embedded systems, ASIC debugging, and processor-level analysis with time-correlated mixed-domain measurements on a single display.
