Debugging that just works. Stable, easy to use, and fully cross platform, Logic 2 makes it dirt simple to capture, visualize, and search your signals.
Explore your board-level comms interactively with Live Trigger on Protocol and Protocol Search. Unlike a scope, all your traffic is being recorded — you can always stop and analyze exactly what happened and why.
Verify behavior instantly with measurements wherever you point your mouse. You can even create your own measurements or use ones from the community.
We really care about this stuff. And we think that when you get Logic in your hands, you’ll be able to tell. Click the circles to learn more about what goes into Logic.
Every Logic starts as extruded 6061 T6 aluminum plate. It is then precisely machined with a 3-axis CNC mill, using four different setups and seven different solid carbide tools.
The machined enclosure is cleaned and then textured with a light glass bead blast to give it a uniform, elegant look. Next the part is anodized, brightened, colored and sealed. This is the finish quality you would expect from pro-audio equipment or a new MacBook.
Choose your favorite color to customize your Logic. The brightness is controlled by PWM, and we’ve RC-filtered the PWM so the LED does not contribute any measurable degradation to your signals.
The low jitter of the ADC sampling clock assures the SNR is not degraded.
Logic 8, Logic Pro 8 and Logic Pro 16 feature the Xilinx Spartan 6 FPGA,which interfaces to the ADC, digital inputs, and USB bridge. The FPGA also has the capability of performing over 5 billion DSP operations per second (over 10 billion on Pro 16). When you use more analog channels than can be streamed over USB at once, we need to filter and decimate that data in the FPGA – reducing the bandwidth without introducing aliasing. Logic Pro 16 produces analog data at a rate of 9.6Gbit – that’s a lot of data to process in real time!
PCB assembly is performed by our assembly partners in Fremont, California. Logic 8 is 8-layer, and Logic Pro 8 and 16 have, well, more layers than that.
To provide optimal signal integrity with a flying lead test probe, each input has a dedicated ground wire. In most situations, users can leave extra grounds disconnected. In addition, on Logic 8, Logic Pro 8, and Logic Pro 16, each input can be configured to be an analog input, a digital input, or both at the same time.
Logic 8, Pro 8, and Pro 16 all have 8-channel ADCs. (Pro 16 has two.) Logic 8 has an analog sample rate of 10MS/s at 10-bits, and Logic Pro 8 and Pro 16 sample at 50MS/s at 12-bits. For Logic Pro 16, this is an awesome 9.6Gbit of data which must be handled by the FPGA. When you use more channels than USB can handle, the FPGA filters and decimates the data in real time so that the resulting signal does not exhibit any aliasing from frequencies above the new bandwidth.
An anti-aliasing filter prevents frequencies higher than the Nyquist frequency from being sampled. Any frequency content higher than Nyquist will result in aliasing, which, generally speaking, makes it impossible to compute an accurate FFT. Filters can have an adverse effect on both gain and phase so this must be carefully accounted for.
When you receive your Logic, it will come in a custom neoprene zippered case, and include a USB cable as well as the test clips (two test clips for every input) and test probes you need.
Depending on your location and the type of shipping selected, your order will ship from our offices in California or a warehouse in the US, Canada, Europe, or Japan.
Not exactly, no. However, it could be much better than an oscilloscope for many applications – especially applications where a microcontroller is interacting with an analog signal in some way, such as reading an analog voltage or controlling an analog voltage.
Logic is not a good fit for the following applications: signal integrity work, high-bandwidth analog signals, small voltages at high resolution (such as less than 100mVpp), or analog voltages outside the range of 0-5V (Logic 8) or -10V – 10V (Logic Pro 8, Logic Pro 16).
Yes, the new software updates are backwards compatible with the original Logic and Logic16!

The first Logic was sold to Chip on June 3rd, 2008. Since then we've sent thousands of Logics all over the world and have gotten some pretty nice feedback. Things are going well!
'Say-lee-ay'. It's just a made up word we came up with a long while back; among other things we went through the periodic table for ideas, and we're pretty confident it was based on Selenium.
