Who says logic analyzers canʼt be beautiful? Saleaeʼs Logic USB Logic Analyzer packs a lot of punch in a small, anodized aluminum package.
- Monitors up to 8 channels
- Saves up to 10 billion samples
- Is multi-platform Windows, Mac or Linux
- Can export data in binary, VCD and CSV
- Supports I2C, Async Serial, SPI, 1-Wire, CAN, I2S, PCM, and UNI/O
Used by students, engineers and hobbyists, Saleaeʼs analyzers have been used for satellites, avionics, submarines, electric cars, and more.
And with the launch of the Saleae Logic 4, 8, Pro 8 and Pro 16 next month, recording, measuring, and annotating will be even easier.

The Logic Pirate is an inexpensive yet capable open source logic analyzer. For just 30 bucks it can sample 8 channels, 256K samples per channel, at a blazing (overclocked!) 60 MILLION samples per second! It’s designed to support the SUMP logic analyzer protocol on Jawi’s open source software that works on most platforms. [via dangerousprototypes.com]

Bob Davis has built an Arduino powered three Million samples per second six channel logic analyzer:
In the video below you can see what the live display looks like. He is using a 74 series decade counter to divide down a 10Mhz crystal so that he has some nice fast stuff to sample. He experimented with the coding style and found that by being a bit verbose with the instructions he was able to speed up the data collection by over 50%. This technique requires a bit more code space and doesn’t look as elegant as a nice tight loop but execution efficiency is the name of the game here.

ScanaPLUS is a robust, versatile and multi-application 9 Channels logic analyzer. It relies on the free ScanaStudio software to capture and analyze logic signals.
This logic analyzer will capture signals at a steady rate of 100 MSPS (Million Samples Per Seconds), whether you’re using 1 or all 9 channels. No compromises.
Thanks to its configurable and fully protected input stage, ScanaPLUS can be directly connected to RS232, to CAN or RS485 differential lines, or to tiny 1.2V logic signals!

A logic analyzer is a powerful debugging tool for capturing many digital signals at once and analyzing their timing relationships. Raj from Embedded Lab has posted a new tutorial that provides a quick overview of a logic analyzer tool and its uses in troubleshooting problems arising from timing violations and transients on microcontroller buses. He used the SCANALOGIC-2 educational kit from IKALOGIC to illustrate the concept of logic analyzer.

The Xprotolab is a combination of 3 electronics instruments: an oscilloscope, a waveform generator and a protocol sniffer. Now Portable
The Xprotolab is a combination of three electronic instruments: a mixed signal oscilloscope, an arbitrary waveform generator, and a protocol sniffer. The Xprotolab was awarded as one of the 100 Hot Products of 2011, by the EDN magazine. The Xprotolab has been featured in several other online magazines, such as Hack a Day. and Elektor.
The Xprotolab has been in development for several years, the hardware and firmware are stable. Now its time to put the device in an enclosure and add a rechargeable battery. The input connectors are going to be 3.5mm stereo audio plugs, and the logic port is going be a 0.1″ male pin connector. The pictures below are from a hand made prototype.

SCANALOGIC-2 EDU KIT (Educational kit) is a fun and educational kit allowing you to build a high performance logic analyzer at home! It’s an even lower cost equivalent to the SCANALOGIC-2 Logic Analyzer whose performances have been proved over the last 3 years. SCANALOGIC-2 EDU KIT is a 20 MHz, 256K Samples, 4 Channels logic analyzer that relies on a PC software (ScanaStudio) to visualise and analyze the captured signals.
