Take the pain out of debugging your embedded systems with a Saleae Logic analyser.

Logic is a logic analyzer used to record, view, and measure digital signals. In addition, Logic currently has 17 different protocol analyzers including serial, I2C, SPI, CAN and many more. Logic can sample each of its 8 channels at up to 24MHz and can record up to 10 billion samples.

  • 4 inputs (1 supporting analog sampling)
  • 12MS/s sample rate (6MS/s for analog)
  • 8-bit ADC
  • Max digital signal 3MHz
  • 2.5 - 5.5V logic levels
  • USB 2.0

The world's best logic analyser, now with analog.

Voltage range

Logic accepts voltages from -.5V to 5.25V, and has standard CMOS thresholds of .8V for logic low, 2.0V for logic high. Input impedance is approximately 1MΩ paralleled by 10pF (see more specs)

Comes complete

Start debugging within 5 minutes of opening your new Logic; everything is included: An ultra-flexible 22AWG 64/40 wire harness, 9 high-quality micro-hook probes, a USB cable (2 meter mini-B to A), and a nice carrying case. Download the software from our site (see software)


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.


We love well made tools. That’s why we love that Seleae make Logic’s case out of custom CNC machined aluminium and make sure its anodized surface is finished to perfection.

Worry free

Logic comes with a 2-year warranty. If your Logic stops working for any reason, Saleae will ship you a replacement at no cost, anywhere in the world. As with any other question or issue, just drop them an email (, and they’ll take care of you.

Top-notch support

Email Seleae anytime. From how to use Logic, to the technical details of your particular application, to what major to choose in college. They'll try to be as helpful as they can.
