Agilent/Keysight 16518A

The Agilent/Keysight 16518A is a 16-channel expansion card that extends logic analyzer capability for timing and state analysis of complex digital systems. This module operates at up to 1 GSa/s for synchronous state analysis across multiple channels and delivers 250 ps timing resolution, making it essential for design verification, debugging, and signal integrity validation in digital hardware development.

– Technical Specifications

• Channels: 16 channels per module
• Timing Resolution: 250 ps across up to 40 channels; 500 ps across up to 80 channels
• Synchronous State Analysis: Up to 1 GSa/s across up to 80 channels
• Maximum Trigger Sequencer Speed: 500 MHz
• Channel Skew: ±250 ps
• Memory Depth: 64K; doubles in half-channel timing mode
• Clock Frequency Range: 20 MHz to 1 GHz (periodic clock required; selectable edge)
• Setup/Hold Time: 750/750 ps across pods (unadjusted); 350/350 ps with manual adjustment; add 0.5 ns for single-clock multi-edge; add 1.0 ns for multi-clock multi-edge
• Data Valid Minimum Time: 2.25 ns when triggering on data faster than 500 MHz

– Key Features

• One timer/counter and one occurrence counter per trigger sequence level
• Pod-based architecture supporting flexible channel expansion
• Half-channel timing mode doubles available memory depth
• Selectable clock edge (positive or negative) for synchronization flexibility

– Typical Applications

• Digital system timing and state capture during development and verification
• Protocol and signal integrity debugging across multiple clock domains
• Hardware validation requiring sub-nanosecond timing resolution

– Compatibility & Integration

The 16518A requires the Agilent 16517A 16-Channel, 4 GHz Logic Analyzer High-Speed State and Timing Module and is compatible with the 16700 Series and 16500C (discontinued) mainframes in the 16517/18A slot.
