Agilent/Keysight 54825N

The Agilent/Keysight 54825N is a 500 MHz benchtop digital oscilloscope engineered for signal analysis, troubleshooting, and design verification across electronics testing applications. Built around a four-channel architecture with 2 GSa/s simultaneous sampling, the instrument delivers 700 ps rise time and 8-bit ADC resolution for accurate waveform capture. An analog-like front panel paired with Windows-based graphical interface accelerates measurement workflows, while advanced triggering modes - edge, pulse width, window, serial protocol, video (NTSC/PAL), and user-defined - enable capture of complex transients as narrow as 500 ps.

The 50,000 waveforms/second acquisition rate supports high-speed repetitive signal characterization. Vertical sensitivity spans 1 mV/div to 5 V/div across 1 MΩ input impedance. Twenty-four stored measurement procedures, drag-and-drop waveform measurement, and onboard math/cursor tools streamline analysis.

The high-resolution color display renders complex signal detail clearly.
