To record your digital and analog signals, just press start. You can fill your entire computer’s memory with data so it is easy to capture lengthy or rare events.
Every Logic device can be customized to capture data the way you want. You can select how long to record, specify how bandwidth is allocated between digital and analog recording, select which channels to record, and even make the LED your favorite color
When you have billions of data points to display, it is important that getting around in all that data is a zippy experience. Effortlessly zoom in and out with the scroll wheel, and navigate left and right by dragging the data where you want it.
For basic measurements, just place your mouse near something interesting. The software will figure out the rest and display the relevant measurements. You can show different measurements by right-clicking.
The software can start recording automatically when it finds a simple pattern you specify. You can trigger on digital edges and pulses as well as analog voltages and pulses. After you collect your data, you can search for more events this way too.
Most digital communication uses a particular protocol that specifies how information is transferred. The Logic software has protocol analyzers that can automatically decode SPI, I2C, serial, 1-Wire, CAN, UNI/O, I2S/PCM, MP Mode, Manchester, Modbus, DMX-512, Parallel, JTAG, LIN, Atmel SWI, MDIO, SWD, LCD HD44780, BiSS C, HDLC, HDMI CEC, PS/2, USB 1.1, Midi – or create your own with the SDK.
Once you have decoded your data with a protocol analyzer, you can search through all these decoded results by just typing what you are looking for – the software will jump right to the spot where it happened.
In the software, you can add unlimited bookmarks, which remember what you were looking at; timing markers, which can measure the time between events; and measurements, which annotate the waveform with parameters like width, frequency, RMS voltage and duty cycle.
Sometimes you will need to do something pretty custom with your data, so you’ll be happy to know it is easy to export it in a variety of formats, including a text csv file or Matlab m file.
If you need to automate the Logic software, you can control everything over a simple TCP socket using virtually any programming language. Learn more.
Have a rare or proprietary protocol you would like to have Logic decode? You can with our Analyzer SDK. Learn more.
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, we currently have two SDKs available. The Automation API lets you control the Logic Software from your own application. The Protocol Analyzer SDK lets you create your own protocol analyzer plugins.
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.
