Saleae Logic 16 - 16-Channel USB Logic Analyzer
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

- Thickness: .39 in (9.8mm)
- Volume: 3.8 in3 (62.2 cm3)
- Weight: 2.6 oz (73.7 gm)
Input Voltages and Thresholds
- Input voltage range: -0.9V to 6V
- Works with 1.8V, 2.5V, 3.3V, and 5V systems
- 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
- Input High Voltage: >= 3.6V
- Over-voltage protection to +/- 50V. Not meant for continuous operation outside -0.9V to 6V.
- ESD protected per CE requirements

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.
- Automated testing against long pseudo-random waveforms at 1MHz and 25MHz, run at 1.8V, 2.5V, 3.3V and 5V.

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.
