The logic analyzer is a waveform test device similar to an oscilloscope. It collects specific signals and displays them to developers using graphics or data statistics. Developers use these graphical timing signals to analyze hardware or software errors according to the protocol. Logic Analyzer is an essential device in design. 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 the logic analyzer to solve problems is very fast. Plug the DuPont cables into the logic analyzer interface one by one. After the DuPont cables are inserted, they are divided into 2 rows. The top row of 5 logic analyzers corresponds to the screen printing on the left side of the shell, and the lower one row corresponds to the screen printing on the right. 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. When the logic analyzer works at 24M, the USB device not only needs to provide a 24M communication rate, but also need to ensure that other devices occupy USB resources before the 4 buffers are filled. For these reasons, the logic analyzer cannot always work at the sampling frequency of 24M for a long time, depending on the computer performance, availability and latency of the USB bandwidth and other devices that occupy the USB drive. The normal operating voltage of the logic analyzer is below 5.5V, the voltage below 1.5V is considered low level, voltage between 1.5V and 5.5V is considered high level, the maximum voltage resistance is 7.5V, please pay attention to the test voltage. › See more product details; Product description Features: Digital Channels: 8 Input voltage range: -0.5V to 5.25V Input voltage: -0.5V to 0.8V Input voltage: 2.0V to 5.25V Works with 5V, 3.3V, 2.5V, 2.0V systems. Works with 1.8V but not recommended. Input impedance: 1 mOhm || 10 pF (typical, approximate) Crystal: +/-20ppm 24MHz Error/Accuracy: Pulse width measurement: +/- 42ns (at 24MHz) Suitable for single chip development, ARM system development, FPGA development. In order for your computer to maximize the sampling rate, you need to ensure the following conditions: 1. Make sure no other major programs record the CPU for a long time. 2. Make sure there is enough storage space, otherwise the computer does not have enough RAM to get the data of the logic analyzer. 3. Connect it as much as possible directly to the USB port of the computer instead of using a USB hub. 4. Try that other USB devices require less USB resources as much as possible. 5. If you want the logic analyzer to have enough power to increase the sampling frequency, use as much as possible. Package includes: 3 x Analyzer 3 x USB Cables 30 x Dupont Cables; Product description Features: Digital Channels: 8 Input voltage range: -0.5V to 5.25V Input voltage: -0.5V to 0.8V Input voltage: 2.0V to 5.25V Works with 5V, 3.3V, 2.5V, 2.0V systems.
