The Keysight 16822A is a 68-channel portable logic analyzer that combines logic analysis, pattern generation, and probing in a single instrument for digital system debugging and validation. Its 15-inch color touchscreen display and deep memory architecture enable comprehensive signal capture and analysis across multiple acquisition depths. The analyzer supports both synchronous state analysis and asynchronous timing analysis, with selectable memory configurations from 1 M to 32 M samples per channel.
