Keysight / Agilent / HP 16950A Logic Analyzer Module

The Keysight/Agilent/HP 16950A is a 68-channel logic analyzer module engineered for high-speed digital system debugging and verification. It delivers timing analysis up to 4 GHz with 250 ps resolution, state analysis to 600 MHz, and selectable memory depths from 256 K to 64 M. The module integrates into Keysight 16900 Series mainframes and scales to 340 channels across five modules, supporting both single-ended and differential signals with threshold adjustment from -3 V to 5 V in 10 mV increments.

Compatibility & Integration The 16950A interfaces with Keysight 16900 Series mainframes and maintains backward compatibility with discontinued 16700 Series and 16500C platforms. Multiple modules combine within a single mainframe, defaulting to the lowest memory depth in the set. The module works alongside other 16700 Series logic analyzer cards (16753A, 16754A, 16755A, 16756A) in multi-card configurations.
