Agilent/Keysight 16822A

The Keysight/Agilent 16822A is a portable logic analyzer that integrates 68-channel signal capture with 48-channel pattern generation in a single instrument. Built around a 15-inch color touchscreen display, it delivers both state and timing analysis for digital system validation across complex designs. The analyzer captures signals at up to 450 MHz synchronous sampling and 4 GHz asynchronous timing zoom, with acquisition memory selectable from 1 M to 32 M depths.

Its pattern generator operates at 300 MVector/s with 16 M vector depth, enabling device substitution, circuit initialization, and full-speed functional testing without external hardware. Signal integrity analysis runs simultaneously across all channels via eye diagrams, accelerating fault identification on high-speed buses. Threshold adjustment spans -5 V to 5 V in 10 mV increments with automated setup for single-ended measurements.

The instrument connects via 10/100 Base-T LAN, six USB 2.0 ports, and standard 40-pin logic analyzer probes, with one PCI and one PCI Express x1 expansion slot for future instrumentation integration. Windows XP or Windows 7 compatibility supports Keysight's native logic analyzer software stack.
