Product Description

System Overview & Key Capabilities

High-Speed Timing
12.5 GHz (80 ps) Timing Zoom with up to 2.5 GHz/5.0 GHz full/half-channel timing analysis.
Deep Memory Capture
Up to 128 Mb/256 Mb deep memory to capture widely spaced anomalies and isolate root causes.
15-Inch Touch Display
Large color touchscreen enables rapid navigation through expansive bus systems and signals.
State Evaluation
1.4 Gb/s transmission rates with 700 MHz status clock frequencies and concurrent eye waveforms.

Configuration & Analysis Details

  • Channel Architecture: 34 channels, 350 MHz state speed, 12.5 GHz timing zoom, 2.5 GHz timing, and 2 MB standard memory depth.
  • Connectivity & Storage: Integrated LAN, high-speed USB 3.0 ports, and an integrated detachable SSD drive ensure rapid transfer and secure storage of extensive data volumes.
  • Trigger Sequencer: Integrated 1.4 GHz trigger sequencer guarantees high-speed trigger event captures.
  • Timing Analysis (Asynchronous Sampling): Full-/half-channel timing up to 2.5 GHz/5.0 GHz records signal activity at ultra-high resolution. 256K memory depth alongside a 12.5 GHz (80 ps) timing zoom allows focused trigger event scrutiny.
  • Status Evaluation (Simultaneous Sampling): Automated threshold and sample placement adjustment ensures exact measurements on high-speed digital buses, coupled with concurrent eye waveforms across channels.
  • Expandability & Upgrade Path: Compatible with single-ended and differential general-use and application-focused probes (sold separately). Adaptable architecture supports field upgrades (use 16861AU to upgrade an existing 16861A).
  • Standard Package Contents: Logic analyzer unit, keyboard, mouse, accessories case, and power line.
