USB Logic Analyzer Device with USB Cable 5MHz 24MHz 8CH 8 Channel UART IIC SPI Debug Logic Analyzer Professional Microcontroller Device Network Analyzing Set for Ardu-ino FPGA ARM M100 SCM
Feature: Digital Channels: 8 Input voltage range: -0.5V to 5.25V Input Low Voltage: -0.5V to 0.8V Input High Voltage: 2.0V to 5.25V Works with 5V, 3.3V, 2.5V, 2.0V systems. May work with 1.8V but not recommended Input Impedance: 1Mohm || 10pF (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.Ensure that no other larger programs take up the CPU for a long time 2.Ensure that there is enough memory space, otherwise the computer will not have enough RAM to obtain the data of the logic analyzer 3.Connect directly to the USB port of the computer as much as possible, rather than through a USB hub 4.Try to make other USB-using devices take up less USB resources as much as possible 5.If you want the logic analyzer to have enough power to increase the sampling frequency, use other USB devices as much as possible Package includes: 1 X Analyser device 1 X USB cable 10 X Dupont cable
Product Features
- Logic analyzer is a waveform test device similar to an oscilloscope. It collects specified signals and displays them to developers through graphics or data statistics. Developers use these graphical timing signals to analyze hardware or software errors in accordance with the protocol.
- Logic analyzer is an indispensable 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 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 will be divided into 2 rows. 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. 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.
- 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. 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.
- The normal working voltage of the logic analyzer is below 5.5V, the voltage below 1.5V will be regarded as low level, the voltage between 1.5V and 5.5V will be regarded as high level, the maximum withstand voltage is 7.5V, so please pay attention to the test Voltage.
