The Hantek DSO2D10 is a budget 2-channel oscilloscope with 100 MHz bandwidth and a built-in function generator. The DSO2D10 features decoding and trigger options like I2C, SPI, UART/RS232 and CAN, which is a nice plus for an oscilloscope in this price range. A unique feature is that there is no fan in the oscilloscope, so it makes almost no noise.
Thanks to a sample rate of 1 GSa/s and a memory depth of 8 Mpts you can easily work with this oscilloscope. There are also USB connections available for exporting measurement results to the PC or to a USB memory stick. There is also a voltmeter to measure AC and DC voltages up to 300 VRMS.
