Of the current models, Saleae’s least expensive 8 line logic analyzer is $479 and the 16 line model is $1399. I purchased an original Saleae Logic 16 Analyzer for $299 and at the time that was kind of a stretch for my budget as I didn’t really expect to use it much (and honestly haven’t – maybe once or twice a year). I ended up at Saleae’s website to download new software, and, to make a long story short, I discovered that the current logical analyzer models are really expensive.
For these reasons, the logic analyzer cannot always work at the sampling frequency of 24M for a long time, depending on the computer performance, the availability and latency of the USB bandwidth, and other devices that are occupying the USB drive. If the logic analyzer works at 24M, the USB device must not only provide a 24M communication rate, but also must ensure that other devices occupy USB resources before the 4 buffers are filled.Before testing the signal, please connect the GND channel of the logic analyzer to the GND pin of the board, otherwise the measured data will be unreliable. The upper row of 5 logic analyzers corresponds to the silk screen on the left side of the shell, and the bottom one row corresponds to the silk screen on the right. After the DuPont cables are inserted, they will be divided into 2 rows. Plug the DuPont cables into the logic analyzer interface one by one.It can quickly locate errors, find and solve problems, especially when analyzing timing, such as 1wire, I2C, UART, SPI, CAN and other data, the application of logic analyzer to solve problems is very fast.
Logic analyzer is an indispensable device in design.
Developers use these graphical timing signals to analyze hardware or software errors in accordance with the protocol. It collects specified signals and displays them to developers through graphics or data statistics. Logic analyzer is a waveform test device similar to an oscilloscope.
