Logic16 - USB Logic Analyzer

Do you need big logic analysis in a small package? That's exactly what the Logic16 delivers. The Logic16 is a 16-channel USB logic analyzer with so much style it'll make your cell phone jealous. Simply connect it to your computer with the included USB cable, attach your test probes and install the Saleae Logic software and you'll be debugging in no time. Along with adding 8 more channels of signal capture, the Logic16 improves on its predecessor by expanding the hardware-side buffer for long captures at high speeds and adding support for 1.8V logic levels, as well as 2.0V, 2.5V, 3.3V and 5V (and the others in between).

Logic16’s inputs are protected against overvoltage conditions by a high DC impedance front end and ultra-low-capacitance diode clamps. A resettable fuse protects the USB ground return line to augment the USB host’s existing protection.

The Logic16 has a rugged, custom-machined aluminum enclosure and can be carried in the included zip-up carrying case (which is small enough to toss in your laptop bag). This is a great field diagnostic tool as well as a welcome addition to any workbench.

Weight: 2.6 oz

  • Logic16 (fully tested)
  • 2 x Ultra-Flexible Test Lead Set
  • 18 x Micro Hook Clips
  • USB A to mini-B Cable (2 Meter)
  • Custom Carrying Case
  • Input voltage range: -0.9V to 6V
  • Works with 1.8V, 2.5V, 3.3V, and 5V systems
  • Input Impedance: 180Kohm || 7pF (typical, approximate)
  • Max Input Bandwidth: 25MHz square wave

Logic16 - USB Logic Analyzer Product Help and Resources

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

4 Electrical Prototyping

Skill Level: Experienced - You will need to consult a datasheet for calculations to determine a components output format, linearity, and do a little math to get what you need. You will be using a datasheet or schematic beyond basic pinouts.

    I used my freeday bonus to purchase this. I'm an old (1980's) Navy ET and was used to high-end logic analyzers, oscilloscopes and other lab-calibrated equipment so I have to say I wasn't expecting much from the Logic16. I've kind of been out of the business for years and recently picked it back up as a hobby.

    I built a little shift register to binary count up 8 LEDs and hooked up the Logic16 to watch SER, RCLK, SRCLK and each of the Q outputs. Beautiful. Not only was the presentation very instructive (I have a good feel for how things work on the 74HC595 now) but the Logic16 actually decoded the serial input so I could see what count was being sent to the 595 and a clock later see that count show up on the Q outputs.

    I'm going to have a blast with this. Oh, and the guys at Saleae are great to work with. Thanks Sparkfun!

    I bought the Logic 16 right after it came out. It's a great piece of kit!

      I concur! I got one for Christmas and have already used it to help bring up a few LCDs on an Arduino. This is a well crafted and versatile tool, and I heartily recommend it.

    Just bought this and it's great. Highly recommended for debugging. The interface (on OSX anyway) is a little "toy" like and is missing some features I'd like, but for the money it's hard to beat. Great for debugging serial protocols etc. Debugging high speed stuff with this is a little tricky (2 ch at 100 MHz is the max it can do) so probably not great for fpga stuff, but it's workable. Definitely a recommended tool for the quiver.

      After playing with this for the past few days I'm frustrated. I want to love this product, but the software is super buggy (at least on the mac). Lots of crashes and lots of just annoying behavior. E.g. channels swapping data (so first you run in and channel 0's data is on channel 0. Then it crashes and channel 0's data is on channel 2). The guys at the company seem awesome and actually answer their phone(!!!). They tried to help out with a beta release. That release fixed one of my problems, but is super unstable (it's a beta) and crashes all the time. UGH....I want to love it, but they're making it difficult to do so....

    Sorry Sparkfun, being regular customer from 2010, i forgot to search this product here & ordered on the company website www.Saleae.com unfortunately, it was out of stock there. so, don't know when i will get it.
