Industry’s Fastest Timing Capture with Deep Memory — for Fast Digital System Debug

The Keysight Technologies, Inc. 16850 Series portable logic analyzers offer the highest performance, with deep, high speed timing and state measurements, combined with the applications and usability your digital development teams need to debug their modern systems — and at a great price.

The logic analyzer’s timing and state acquisition gives you the power to:

  • Observe timing relationships far away from the trigger point using 2.5 GHz (400 ps)/5 GHz (200 ps) full/half channel timing with up to 128 M samples
  • Measure more precise timing relationships in the vicinity of the trigger point using 12.5 GHz (80 ps) Timing Zoom (256 K samples)
  • Find anomalies separated in time with memory depths upgradable to 128 M
  • Probe a variety of technologies with single-ended and differential attachment options with the highest signal integrity
  • Buy what you need today and upgrade in the future. 16850 Series logic analyzers come with independent upgrades for state speed and memory depth
  • Sample synchronous buses up to 1400 Mbps data rates accurately using eye scan to automatically adjust threshold and setup/hold
  • Easily track problems from symptom to root cause across several measurement modes by viewing time-correlated data in waveform/chart, listing, inverse assembly, source code, or compare display
  • Identify potential signal integrity issues on high data rate signals by observing an analog view of all input channels via logic analyzer probing with “eye scan”
  • Set up triggers quickly and confidently with intuitive, “simple,” “quick,” and “advanced” triggering options
  • Time correlate and import oscilloscope/mixed-signal traces into the logic analyzer Waveform window for even greater system insight

Automate measurement setup and quickly gain diagnostic clues

16850 Series logic analyzers make it easy for you to get up and running quickly by automating your measurement setup process. In addition, the logic analyzer’s setup/hold window (or sampling position) and threshold voltage settings are automatically determined so you can capture data on high-speed buses with the highest accuracy. Auto Threshold and Sample Position mode allow you to...

  • Obtain accurate and reliable measurements
  • Save time during measurement setup
  • Gain diagnostic clues and identify problem signals quickly
  • Scan all signals and buses simultaneously or just a few
  • View results as a composite display or as individual signals
  • See skew between signals and buses
  • Find and fix inappropriate clock thresholds
  • Measure data valid windows
  • Identify signal integrity problems related to rise times, fall times, data valid window widths

Identify problem signals over one hundred channels simultaneously

As timing and voltage margins continue to shrink, confidence in signal integrity becomes an increasingly vital requirement in the design validation process. Eye scan lets you acquire signal integrity information on all the buses in your design, under a wide variety of operating conditions, in a matter of minutes. Identify problem signals quickly for further investigation with an oscilloscope. Results can be viewed for each individual signal or as a composite of multiple signals or buses.

Seamless oscilloscope integration with View Scope

Easily make time-correlated measurements between Keysight logic analyzers and oscilloscopes. The time-correlated logic analyzer and oscilloscope waveforms are integrated into a single logic analyzer waveform display for easy viewing and analysis. You can also trigger the oscilloscope from the logic analyzer (or vice versa), automatically de-skew the waveforms and maintain marker tracking between the two instruments. View Scope allows you to perform the following more effectively:

  • Validate signal integrity
  • Track down problems caused by signal integrity
  • Validate correct operation of A/D and D/A converters
  • Validate correct logical and timing relationships between the analog and digital portions of a design

Programmability

You can write programs to control the logic analyzer application from remote computers on the local area network using COM or ASCII.

The COM automation server is part of the logic analyzer application. This software allows you to write programs to control the logic analyzer. All measurement functionality is controllable via the COM interface.

The B4608A Remote Programming Interface (RPI) lets you remotely control a 16850 Series logic analyzer by issuing ASCII commands to the TCP socket on port 6500. This interface is designed to be as similar as possible to the RPI on 16700 Series logic analysis systems, so that you can reuse existing programs.

The remote programming interface works through the COM automation objects, methods, and properties provided for controlling the logic analyzer application. RPI commands are implemented as Visual Basic modules that execute COM automation commands, translate their results, and return proper values for the RPI. You can use the B4606A advanced customization environment to customize and add RPI commands.
