Hantek 2D42 - 2-channel portable 40MHz oscilloscope with signal generator

Description

Portable digital oscilloscope with built-in signal generator and multimeter. It features a 2.8" TFT LCD display with 320x240 pixel resolution and adjustable contrast. It has two measurement channels and features good performance, including 40 MHz bandwidth, 250 MSa/s sampling rate and 6K memory buffer. In addition, the oscilloscope offers a single-channel signal generator with waveform frequencies up to 25 MHz, which has the ability to generate sine wave, rectangular signal, triangular signal and noise. It also allows the device to be used as a multimeter to measure AC and DC voltage, AC and DC current, resistance and capacitance. It is powered by a built-in rechargeable battery and charged via a USB Type C connector. It is a useful measurement tool widely used in various fields such as communications, aerospace, embedded systems, computers, research and education.
