Logic Pro 8 (Black) - Saleae 8-Channel Logic Analyzer

Product Information

Now if I could only find a decent USB 2.0 oscilloscope. I think though, that that’s one realm where I still need a real device, perhaps with a decent USB transfer and control interface. 250MS/sec+, 2+ channels, 600V+ and decent triggering options (say an external trigger that I provide with the logic analyzer?) wooddragon48 has updated components for the project titled 3D Printed Repeating Crossbow/Sling Shot Pistol.

The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source signal analysis software suite that supports various device types (e.g. logic analyzers, oscilloscopes, and many more). Big DNL spikes caused by an apparent mismatch between capacitors used in simulation and production, James Adams confirms. Raspberry Pi confirms there is a hardware flaw in the RP2040 ADC. Refer to the RP2040 datasheet build-date: 2021-11-04, build-version: 150df05-clean, sections “4.9.3. ADC ENOB”, “4.9.4. INL and DNL”, and in-datasheet errata “RP2040-E11”.[1] Logic analyzers take the guess work out of debugging inter-chip communication. If you can’t see what’s going on, the best you can do is guess about the problem. When a project won’t work, 99% of the time we can solve the problem immediately by looking at the signals with a logic analyzer. Without it, there’s no easy way to know what’s happening.

We really like the profiles that decode most common serial protocols; 1-Wire, I2C, SPI, and asynchronous serial. CAN and other protocols will be added eventually.

Cross-platform. Works on Linux, Mac OS X, Windows, FreeBSD, OpenBSD, NetBSD, Android (and on x86, ARM, Sparc, PowerPC, ...). Broad hardware support. Supports many different devices (logic analyzers, oscilloscopes, multimeters, data loggers etc.) from various vendors. The Logic records 8 channels at 24MHz. The Windows software has useful features, and there’s an SDK if you want to write your own apps. Linux and Mac versions are under development. We really like this logic analyzer, and plan to use it to illustrate future articles. We also tried the 1-Wire decoder with a DS2431 EEPROM. The software identified the 1-Wire reset command, and the 1-Wire ‘search rom’ command (0xf0).ericwertz – if you need to look at 50mhz digital data, then 100Mhz sampling is not nearly enough. Nyquist theory is meaningful for analog analysis, and is a limitation that applies directly to the highest frequency pure sine wave component of the signal – exclusive of phase. Digital analysis is very different. You could barely represent a square wave sampling at Nyquist, and thus would get virtually no timing information from the resulting waveforms. You’ll need to sample 4-10 times your bus rate to get meaningful timing information. There are Differential Non-Linearities [2] and Integral Non-Linearities [3] caused by mis-matching of on-die ADC capacitors. Ian – re other products: I don’t want to post a commercial for anyone, so I won’t mention my favorite by brand name. Just do a google search for “logic analyzer”. There’s about a zillion products in this price range out there these days. File format support. Supports various input/output file formats (binary, ASCII, hex, CSV, gnuplot, VCD, WAV, ...). When it debuted, the Logic was so popular that it was hard to buy one. It’s now widely available, and Saleae gave us one to try. Read our review below.
