Agilent/Keysight 1671D

The Agilent/Keysight 1671D is a benchtop logic analyzer built for debugging and characterizing digital circuits and embedded microprocessor systems. This 102-channel instrument captures signal activity across state and timing domains, enabling engineers to isolate timing violations, protocol errors, and hardware faults in complex digital designs.

– Technical Specifications

• Channels: 102
• State Analysis: 100 MHz on all channels
• Timing Analysis: 125 MHz on all channels; 250 MHz on 1/2 channels
• Memory Depth: 64K samples (all channels); 128K samples (1/2 channels, timing mode only)
• Minimum Detectable Glitch Width: 3.5 ns

– Key Features

The 1671D operates in both state and timing acquisition modes, allowing you to monitor signal relationships at the clock edge or measure asynchronous glitch activity with nanosecond resolution. The 3.5 ns glitch detection capability resolves transient anomalies that escape slower instruments. Dual memory configurations optimize capture depth based on channel count and analysis mode.

– Interfaces & Storage

Internal hard drive provides persistent mass storage for capture data and instrument configurations. A 3.5-inch high-density floppy drive supports DOS and LIF file formats for portable data exchange. LAN connectivity via 10Base-T and 10Base-2 connectors enables remote control and network-based data transfer.

– Typical Applications

Logic analysis of microprocessor debug signals, verification of bus protocols, timing correlation across multiple clock domains, and transient fault isolation in embedded systems.
