Saleae Logic - PC based Logic Analyzer

Logic’s inputs are protected against overvoltage conditions via current-limiting resistors and ultra-low-capacitance diode clamps. A resettable fuse protects the USB ground return line to augment the USB host’s existing protection.

Inputs

  • 8 Inputs
  • Voltage Range: -0.5 to 5.25V
  • Input Low Voltage: -0.5 to 0.8V
  • Input High Voltage: 2 to 5.25V
  • ESD and over-voltage protection
  • Logic threshold not adjustable
Sample Rate & Depth
  • 24MHz Maximum Sample Rate
  • 200M+ samples, absolute limit depends on system ram

The limit compare mode provides pass/fail indicators to quickly show if a test passes or fails to help eliminate mistakes, especially for results that are close to the limit.

5.5 digit resolution Measure volts, ohms and amps with a basic V dc accuracy of 0.015%. Frequency measurements Save cost and bench space by replacing a multifunction DMM and counter with one instrument.

DC leakage current measurements Make sensitive low current measurements with 1 nA resolution. Dual display Measure two different parameters of the same signal from one test connection. PC Connectivity Easily connect to a personal computer using RS-232 or USB.
