Logic analyzer Saleae Logic 8 & Logic Pro 8 & Logic Pro 16

I. Specification of Logic signal analyzer Saleae Logic 8 & Logic Pro 8 & Logic Pro 16

Logic analyzer Saleae Logic 8 & Logic Pro 8 & Logic Pro 16 is an 8 channel and 16 channel logic analyzers with each input dual purposed for analog data recording.

This Logic analysis equipment connects to a PC over USB and uses the Saleae Logic Software to record and view digital and analog signals.

It operates by sampling a digital input connected to a device under test (DUT) at a high sample rate. These samples are recorded to a sample buffer, and at the end of the capture, the buffer is displayed in the software for review.

Logic analyzers are great for debugging embedded applications. In the most common case, a developer working on firmware for a microcontroller will write code to communicate with another component, possibly using protocols like serial, I2C, or SPI.

To verify the functionality or to diagnose errors in the firmware, a logic analyzer is connected to the digital IO used for communication and records the activity during testing. The recording is then shown on the display so the user can view the actual behavior of the firmware, and compare that with the expected behavior to narrow down and identity the source of the issue – or verify that the operation is correct.

II. Logic analyzer Saleae Logic 8 & Logic Pro 8 & Logic Pro 16 - Debug hardware like a pros

Protocol decoders:

• Effortlessly decode protocols like SPI, I2C, Serial, and many more. Leverage community created analyzers or build your own low-level or high-level protocol analyzer.

It just works:

• 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.

Trigger and Search:

• 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.

 

Measurements:

• Verify behavior instantly with measurements wherever you point your mouse. You can even create your own measurements or use ones from the community.

SDK, Extensions and Community:

• Take on any comms challenge by creating your own low-level protocol analyzer, high-level protocol analyzer, or measurement. And if you like, you can easily share your extension with the Saleae community.

III. Craftsmanship in the design of Saleae Logic 8 & Logic Pro 8 & Logic Pro 16 Debugging Tools

Machined aluminum:

• 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.

Metal finishing:

• 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.

RGB LED:

• 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.

Low-jitter ADC clock:

• The low jitter of the ADC sampling clock assures the SNR is not degraded.

FPGA:

• 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:

• PCB assembly is performed by assembly partners in Fremont, California. Logic 8 is 8-layer, and Logic Pro 8 and 16 have, well, more layers than that.

Dual-Use inputs and Signal integrity:

• 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.

ADC:

• 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.

Anti-aliasing filters:

• 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.
