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

• Time-Interval Accuracy: ±200 ps
• Logic Probe Organization: 3 pods, 8-bit + 1 parity bit + clock per pod

– Key Features

• Logic State Triggering: Up to 27 channels with missing and extra bit modes
• Logic Trigger Qualification: Parallel and serial trigger qualification capabilities
• Automatic Waveform Measurements: Parametric analysis with user-defined thresholds
• Waveform Math: Ch1+Ch2 and Ch1-Ch2 operations
• Display Modes: Infinite persistence, envelope, and average; auto-scaling of input signals
• Event-Based Holdoff: Trigger acquisition after a specified number of events
• Pre-trigger Viewing: Capture events before the trigger point

– Typical Applications

Mixed-signal debugging, logic state verification, serial protocol analysis, and embedded system characterization requiring simultaneous analog and digital signal observation.

– Compatibility & Integration

HP-IB (IEEE-488) interface enables full remote control and integration into automated test environments. Supplied with two HP 10017A 10:1 divider probes, three HP 10271A 10-bit state data probes, BNC adapter, and complete documentation.
