A logic analyzer is a device that lets you watch digital signals in your electronics project. Unlike an oscilloscope, its not good for measuring analog signals — but also unlike an oscilloscope, you can track 16 signals at time! So its a good complementary tool. This logic analyzer plugs into a computer and has easy to use cross-platform software. This makes it small, portable and inexpensive. If you ever have to to debug SPI, i2c, serial, CAN, 1-wire, Manchester, biphase or other digital protocols, this tool is essential!
Speedy 100MHz Logic samples each channel at up to 100 million times per second! The sample rate is flexible and based on number of channels: Sample 2 channels at 100MHz, 4 channels at 50MHz, 8 channels at 25MHz, or all 16 channels at 12.5MHz. A large fraction of practical, real world applications run at less than 10MHz, and Logic is ideal for these.
16 Channels Logic16 has 16 inputs — it can monitor 16 different digital signals at once. For many modern microcontroller-based designs, this is plenty.
10 billion samples Logic can save as many as 10B samples, letting you capture even the most elusive events. No more dealing with frustratingly small sample buffers.
1.8V logic welcome Works with 1.8V to 5.0V logic levels
Comes complete Start debugging within 5 minutes of opening your new Logic; everything is included: An ultra-flexible 22AWG 64/40 wire harness, 18 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)
Enclosure We love well made tools. That’s why we make Logic16’s case out of custom CNC machined aluminum and make sure its anodized surface is finished to perfection.
Protection Logic’s inputs are protected against over-voltage 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.
Worry free Logic16 comes with a 2-year warranty direct from the manufacturer as well as email support

Threshold Setting 1 (for 1.8V to 3.6V)
Input Low Voltage: <= .7V
Input High Voltage: >= 1.4V
Threshold Setting 2 (for 5V)
Input Low Voltage: <= 1.4V

Over-voltage protection to +/- 50V. Not meant for continuous operation outside -0.9V to 6V.
ESD protected per CE requirements
180Kohm || 7pF (typical, approximate)
Maximum Input Bandwidth
25MHz square wave
Tolerant of simultaneous switching on up to 8 channels at all voltages.
Note that unused inputs may exhibit crosstalk if left floating. If desired, unused inputs can be disabled.
Pulse-width measurement: +/- 10ns @ 100MHz, +/- 20ns @ 50MHz, +/- 40ns @ 25MHz, +/- 80ns @ 12.5MHz
Maximum Sample Rates
100MHz when using 2 channels, 50MHz when using 4 channels, 25MHz when using 8 channels, and 12.5MHz when using 16 channels. 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.
Available Sampling Rates
100MHz, 80MHz, 50MHz, 40Mhz, 32MHz, 25MHz, 16MHz, 12.5MHz, 10MHz, 8MHz, 6MHz, 5MHz, 4MHz, 2MHz, 1MHz, 500KHz, 250KHz
Up to 10B samples. Absolute maximum depends on data compressibility, available RAM and operating system. 10B samples assumes reasonably high compressibility.

Safety & Equipment Protection
Logic16 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 Logic16) 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.
For other DUTs, isolation can typically be achieved through the use of a dedicated isolation transformer (such as those made by Tripp-lite).
When using USB powered DUTs, special care should be taken to avoid connecting USB sourced power to Logic16’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.
