Agilent/Keysight 54201D

The Agilent/Keysight 54201D is a two-channel digitizing oscilloscope built for waveform acquisition, analysis, and logic state monitoring. It delivers 300 MHz repetitive bandwidth and 50 MHz single-shot bandwidth through dual 200 MS/s digitizers, enabling precise capture of analog signals alongside advanced logic triggering on up to 27 channels. The instrument combines conventional oscilloscope triggering with specialized logic probe capabilities, pre-trigger viewing, and multiple display modes - infinite persistence, envelope, and average - making it suitable for mixed-signal applications requiring both analog and digital insight.

Technical Specifications

• Repetitive Bandwidth: 300 MHz


• Single-Shot Bandwidth: 50 MHz
