Hantek Digital Oscilloscope
Third, on our list is the Hantek Digital Oscilloscope, which functions as a multimeter and an oscilloscope. The oscilloscope’s parameters are balanced in the channel mode. For the Dual Channel mode, it reaches a max speed of 35 MHz, making it one of the faster devices in its department.
The Hantek Digital Oscilloscope is perfect if you’re on a budget. For instance, it is comfortable, but it doesn’t have a rotating knob to help select menu parameters and control the signal trigger. However, users start to get used to its device’s push-button control, which ensures better mobility once its in use.
Software is needed if you want your oscilloscope to work well, and the DSO Analyzer helps you register measurement parameters with the assistance with a computer. Thus, giving you more accurate readings that you can share, save, and utilize when using this device.
Its memory depth is one thing that makes it superior to competing brands. The single band channel holds 32k memory, and 16k memory is for the dual-band channel. So you’ll have enough memory to keep multiple data sources within reach.
The Hantek Digital Oscilloscope has over 6 hours of battery power, making it great for daily use. Think that’s enough? It comes equipped with two channels with a 2GS sample rate through each of them. Thus, improving the accuracy of your readings, with the help of this oscilloscope.Check Price
