Agilent/Keysight 54846B

The Agilent/Keysight 54846B is a 600 MHz, 4-channel digital oscilloscope built for precision waveform capture and analysis in communications, aerospace, and automotive test environments. It delivers 8 GSa/s sample rate with configurable memory from 128 kpts to 2 Mpts per channel, 8-bit vertical resolution, and advanced triggering across eight modes including edge, pulse width, video, and pattern detection. The color LCD display supports variable persistence and intensity grading, while over 50 automatic measurements, FFT analysis, and waveform math functions enable rapid signal characterization.

Trigger jitter stays below 50 ps RMS.
