This high sampling speed, coupled with its 10M general applications, makes it possible to handle various scenarios with ease. Additionally, the device has overpressure protection, which ensures that it functions safely during the operation. One of the most significant advantages of the USB logic analyzer is its ability to choose sampling rates from 24 MHz to 25 kHz, making it highly versatile for different applications. The data upload is in real-time, making it easier to analyze signals as they occur. The device comes with a set of 10 colored DuPont lines, a high-quality USB-MINI line, and a host logic analyzer, making it a complete package.
Principle of Work:
The principle of work for a USB logic analyzer is relatively simple. It is designed to capture digital signals and convert them into a form that can be analyzed by a computer. The device works by connecting to a computer via USB and capturing signals through its input channels. The USB logic analyzer is designed to work with different digital signals such as UART, I2C, SPI, and CAN, among others. When connected to a digital device, the logic analyzer captures the signals transmitted by the device and converts them into a format that can be analyzed by the computer. The device then sends the captured data to the computer in real-time, allowing for real-time signal analysis. The USB logic analyzer works by sampling the digital signals at a specific rate, depending on the application. The device can sample at different rates, depending on the required accuracy and speed of the signal analysis. Once the data is captured and converted into a format that can be analyzed by the computer, the software can then be used to analyze and interpret the signals. The USB logic analyzer software allows users to set up trigger conditions, which help to filter out unwanted data and only capture specific signals of interest. This feature is particularly useful for hardware debugging and signal analysis, as it allows for accurate and targeted analysis of specific signals.
Pinout of the Module:
- USB: This is the main connection that allows the logic analyzer to communicate with a computer. It is used for both data transfer and power supply.
- Input channels: CH0-CH7 logic analyzer typically has multiple input channels, which are used to capture digital signals from the device being analyzed. The number of channels is 8 in this specific model.
- Ground: In order to capture accurate signals, you have a ground pin or terminal that can be connected to the ground of the device being analyzed.
The USB logic analyzer can be used for a variety of applications, including digital circuit testing, microcontroller development, firmware debugging, and signal analysis for communication protocols like UART, SPI, and I2C. It can help to identify issues in data transfer and signal timing, making it useful for electronics engineers, computer hardware technicians, and hobbyists working on electronic projects. The high sampling rate and real-time data upload make it suitable for high-speed signals and time-critical applications. The overpressure protection feature ensures safe operation and protects the device from damage due to voltage spikes.
