Logic analyzer is an instrument that collects and displays the digital signal from the system under test. It's mainly used for timing judgment and analysis. Unlike the oscilloscope with many voltage grades, it has only two grades (Logic "1" and Logic "0") but can provide better accuracy, much more data and more complicated measuring methods. Features: The kit includes a logic analyzer with 20P cable, 9P cable, 2P cable, 20 connectors, a 1.5m USB 2.0 cable, a software CD and an user manual. The input voltage range is -50V to +50V, with adjustable threshold of -4V to +4V. Compatible with various level standards: 5V TTL, 5V/ 3.3V/ 3.0V/ 2.5V/ 1.8V/ 1.5V/ 1.2V/ 0.9V CMOS and etc.. USB 2.0 data transmission, real-time upload of sampling data to the computer, the higher the sampling rate, the less the channel number. The sampled data can be exported to the format of txt, csv, bin, etc., the decoding data display supports the format of Binary, Decimal, Hexadecimal, ASCII, ASCII & Hexadecimal. Multiple measuring functions in the computer software; linkage between waveform window and analysis result window for convenient data checking and analysis. Exquisite plastic casing, sturdy and durable, compact size and lightweight, easy to carry. Note: 1. The logic analyzer and the computer have the common GND. It it's connected to not isolated inverter equipment, frequency-changing equipment or 220V/ 380V direct power supply equipment, the logic analyzer or even the computer may be destroyed 2. Size and color may be slightly different due to manual measurement and different light conditions. Thank you for understanding.
