Tech Specs

Geometry and Weight

  • Length & Width: 1.7 in (43.2mm)
  • Thickness: .365 in (9.3mm)
  • Volume: 1 in3 (16.4 cm3)
  • Weight: .9 oz (25.5 gm)


  • Input voltage range: -0.5V to 5.25V
  • Input Low Voltage: -0.5V to 0.8V
  • Input High Voltage: 2.0V to 5.25V
  • Works with 5V, 3.3V, 2.5V, 2.0V systems. May work with 1.8V but not recommended.
  • ESD protected per CE requirements
  • Over-voltage protection to +/- 15V. Not meant for continuous operation outside -0.5V to 5.25V.
  • Input Impedance: 1Mohm || 10pF (typical, approximate)
  • Error/Accuracy: pulse-width measurement: +/- 42ns (at 24MHz).

Sample Rate & Depth

  • 24MHz. 16MHz, 12MHz, 8MHz, 4MHz, 2MHz, 1MHz, 500KHz, 250KHz, 200KHz, 100KHz, 50KHz, 25KHz; Note that achieving the highest sample rates requires low USB latency; this may not be achievable on all computers. Performance may improve with the removal of other USB devices, using a different USB host controller, or increasing the software's process priority.
  • 10B samples. Absolute max depends on data compressibility, available RAM and operating system. 10B samples assumes reasonably high compressibility.

System Requirements

  • Windows XP (32-bit)
  • Windows Vista (32-bit or 64-bit)
  • Windows 7 (32-bit or 64-bit)
  • Mac OS X 10.4 Tiger or higher
  • Linux: recent Ubuntu, Fedora, or openSUSE. Other distributions are likely to work but not specifically supported.
  • USB 2.0

Safety & Equipment Protection

  • For more detail, please see the section Safety & Equipment Protection near the end if the User's Guide
  • Logic may not be used with DUTs (devices under test) which are not electrically isolated from MAINS (i.e. wall power).
  • DUTs which are battery powered, or USB powered (from the same computer as Logic) are acceptable.
  • DUTs powered by AC adapters which have only 2 prongs, and do not have an earth ground connection (such as most "wall warts"), usually provide MAINS isolated power and are acceptable.
  • When using USB powered DUTs, special care should be taken to avoid connecting USB sourced power to Logic's ground, as this provides a short-circuit return path. While both Logic16 and USB ports are designed to survive a short circuit event, care should be taken to minimize its likelihood.
