A Digital Storage Oscilloscope (DSO) for under $70.00

The Hantek 6022BE  Digital Oscilloscope is a fully functional Digital Storage Oscilloscope (DSO) priced at less than $70.00. This unit is designed to operate with a personal computer which greatly reduces the cost of manufacture by using the Computer Screen as the display and the keyboard as the function controls.

The Hantek 6022BE  oscilloscope features a 20 Mhz bandwidth with a 48 MSa/sec sampling rate, which is suitable for general electronics use. This provides sufficient capability for viewing a multitude of waveforms encountered in design, servicing, and educational environments.

Although this model does not have external triggering c

apabilities, it does not limit the usefulness since Channel 2 could be used as an external trigger input. The oscilloscope features various trigger modes and settings, including auto, normal and single.

Even though this is a low cost unit, it still features various mathematical operations that may be performed on the waveforms applied to the two channels. The operations available are Addition (CH1+CH2), Subtraction (CH1-CH2 or CH2-CH1), Multiplication (CH1 * CH2), Division (CH1/CH2 or CH2/CH1), and Fast Fourier Transform (FFT). The FFT operation is useful for observing the frequency content of the waveform.

The Hantek 6022BE  Digital Oscilloscope was found to be easy to use and included features not normally found on units in this price range. The unit performed at or better than the published specifications through all of the available functions. If higher Bandwidth is required, Circuit Specialists offers models ranging from 20 Mhz up to 200 Mhz.
