Featuring 3MHz analog bandwidth, a maximum sampling rate of 16MS/s, and support for decoding communication protocols such as I2C, SPI, UART, and CAN, it is suitable for electronics development, embedded systems debugging, and digital circuit troubleshooting.
Product Description
The LHT00SU1 Virtual Oscilloscope and Logic Analyzer is a compact, PC-connected test instrument designed for electronics engineers, technicians, students, and hobbyists. It integrates multiple measurement and signal-analysis functions into a single USB device, providing a practical solution for testing analog waveforms, analyzing digital signals, and troubleshooting communication interfaces.
The oscilloscope function offers a maximum analog bandwidth of 3MHz and a maximum sampling rate of 16MS/s. Its specified analog input voltage range is -10V to +10V, making it suitable for observing low-frequency signals in electronic circuits within the instrument's operating limits.
The integrated 8-channel logic analyzer captures digital signals and supports protocol decoding for I2C, SPI, UART, SMBus, I2S, CAN, 1-Wire, PS/2, parallel communication, and other listed protocols. This makes the LHT00SU1 useful for debugging microcontrollers, development boards, embedded systems, and digital communication interfaces.
Beyond waveform and logic analysis, the device provides additional functions including data logging, voltage measurement, frequency measurement, frequency generation, PWM control, I2C control, and pulse or edge counting, depending on the available software functions.
The LHT00SU1 connects to a computer through a USB 2.0 High-Speed interface. Compatible software allows users to view, capture, and analyze signals on the computer screen, making the device a space-saving alternative for basic electronic testing and development tasks.

Important Usage Notes
The LHT00SU1 is intended for low-frequency analog measurements and digital signal analysis. Its 3MHz analog bandwidth is not suitable for applications requiring a high-bandwidth oscilloscope.
The analog input range of -10V to +10V is different from the digital input range of 0V to 5.3V. Always observe the specified input limits and grounding requirements when connecting the device to a circuit.
Although CAN protocol decoding is listed as supported, this does not establish that the device includes a dedicated CAN transceiver. A suitable CAN signal connection and compatible decoding software may be required.
The two analog input channels should not be assumed to support simultaneous sampling, because the published specifications identify only one sampling channel.
