Owon VDS1022I 25MHz USB PC Oscilloscope with MIT USB Isolation - Perfect for Electronics Testing, Circuit Debugging & Engineering Education

I both own and have used many digital and analog scopes due to my career as an engineer. However, I wanted an inexpensive scope that can be used with a PC for presentations. I bought a Hantek 6022BE for that purpose, and while it is very similar in features and performance to this OWON VDS1022i and nearly half the price, the software was not very good. The OWON was purchased based on positive reviews. I was not disappointed. While the features and performance are good for an inexpensive scope, the software is a big improvement to the Hantek. One example is the FFT feature, which I use, is pretty useless in the Hantek as it is displayed in a manner that does not make it easy to view or take readings. The OWON allows for a better display of the spectrum information and allows for easy measurement as well. Preset measurements, such as rms, rise time, etc., are much better with the OWON. The software allows for Printing, Screen Capture, and saving the data of the wave form(s) in a file with several popular formats to choose from.Now as an oscilloscope it has the advantages (easy to save and display data) and limitations (low bandwidth and waveform distortion near the the top end due to low sampling rate) of an inexpensive digital scope. The 25 MHz bandwidth is limiting, but the 100 MS/sec allowed for display of about 30MHz sinusoidal signals with minimal distortion. The record length is surprisingly limited at 5 kB. It comes with 2 basic 60 MHz, hard plastic, 1x/10x probes. [The Hantek's are a bit better.] It was relatively easy to setup with the software, documentation and drives included on a CD. You can download all the material from their website as well. The units gets it power directly through the usb connection on my laptop. However, it has an additional usb connector that can be plugged into a 5vdc power supply if you wanted to use it on an Android phone like the Hantek can with a proper adapter and software not included. It runs well on my 8 year old HP laptop (i7 with 8 MB)using the latest version of Windows 10.
