Hantek 6022BE Digital Oscilloscope Portable PC Based 2 Channels 20MHz USB Oscilloscopes

Hantek 6022BE PC Oscilloscope as of 2022-10-11Findings so far on the properties of the device.The face of the product shows the two input channels in a lovely colored green for channel one and blue for channel two on the silk screening, however, when connected to the PC can only display the same trace color for both channels. Would be nice having different trace colors on the screen as well not just on the silk screening of the face plate.Second, it states +/- 35 volts AC/DC on the silk screen face plate. Well, that is not entirely true. 35 volts is ONLY when used with the 10X setting on the probe, otherwise it will be only 3.5 volts RMS in the X1 position before it shows clipped on screen. So the max. AC voltage would be 35 x 2.82 for 98.7 V p-p on this product using 10x probe setting. Any further will start to have internal diodes conduct and show clipped waveform on the screen. Keep this in mind when using with large power amplifiers, high voltage power supplies, etc. You may need to build an external attenuator if subjected to greater voltages or alternative probes with greater attenuation ratios.I received my unit with a USB cable with twin ends on one end of the A side, and single B side as normal B hookup to the device. I don’t know why two A connectors are needed since it appears to work with a single A cable. My thoughts were that for other models, it may be due to the added current requirements from USB ports. I don’t believe it has to do with communication speeds for data flow. So now I am using my unit with my own 7 foot cable to have greater distance to the other side of my bench.Every now and then, I have noticed when I enabled the data output window to see the measured parameters that the control panel screen would be such that I can’t get to the top of the screen back to setting the time base of the horizontal window. It would only show about have the blue knob and I would have to restart the program to reset the issue. Probably a bug in the code.Another thing I have noticed with this product is that after it has been running for a period of time it on occasion will just freeze and you would have to either restart the software and other times physically unplug the USB cable and reinsert it to get the software to recognize the scope is present. I don’t know why this happens, but I have noticed this the other day as I was using it throughout the day. It must have locked up on me 3 or 4 times which is strange in my view.Another issue with this product is that I can’t see phase angle measurements either in the output window or with the screen. I can see the offset wave forms but not the actual numeric values of the waves displayed. Would be nice to see phase angle measurement values on the screen as my old Tektronix would display. That been said, also the ability to scroll the horizontal time line to see history of the captured events. And also, when it comes to viewing things such as rise time on the screen, well, you can’t really magnify this to see much detail if any to my findings so far. I played with the different time bases to try and see how much you can see the slope of the wave but just can’t magnify the slope. Also, when it comes to triggering, you can’t enter a value that you would want to trigger manually, you can only use the mouse and drag an arrow cursor to the approximate area. If I don’t have a mouse to drag the curser, I can’t use the up or down arrow keys on the keyboard. With my Tektronix, I can with the knob use fine and course tracking options to be more precise in setting the voltage parameters. This also goes for the horizontal and vertical cross hair options, none to fine tune the areas of interest only your mouse dragging abilities.Another issue that is annoying is the FACT that so far any measurements that take longer than one second for the sweep would only show a fractional amount of the screen traced when you increase the time period setting. Example, if I selected a time of 100 millisecond for ten horizontal divisions, then it takes one second before you get anything drawn on screen which is fine and the full screen captured content is displayed. However, if the time is set greater than one second, for example, 10 seconds per div., now it only shows you the first division of the ten divisions in the horizontal grid traced and 9 of them nothing, blank. This is not good at all. I posted pictures of this event to show my point here. So basically what I am saying is that for slow timing events that take longer than one second to accomplish can not be properly displayed on this instrument. I can do the same experiment with my Tektronix and have no issues to actually watch and see the full trace sweep being plotted out perfectly. This was one of the reasons why I wanted this product to do timing discharge curves on capacitors now realizing that it is not performing in doing a full horizontal trace on the screen. My Tek. only can do 10 seconds / div. so when I seen 5000 seconds on this product, I was impressed. Now I see that my Tek is actually beyond this product for this matter but limited to only 100 seconds but 10 times better than this product for the actual proven operational working time base parameters.For things like AC ripple riding on a DC rail, you would most likely add your own DC blocking capacitor tor your probe to see the AC ripple content. Not a big deal if that is what you are trying to measure.The main reason why I purchased this product was that my old Tektronix was acting up from time to time and I did not want to spend large on a new scope since I can’t see the point anymore spending so much on buying technology that now is throw away for the most part. So this product costed me $79 plus shipping for slightly under $100 dollars which I was prepared to accept along with any losses over time out of the warranty period. I am sure that it will be fine for the warranty period and beyond for now.So far the good things about this product are,1. No noisy FAN’s, totally silent, absolutely GOLDEN!2. Compact, takes very little space, not in your face.3. For BASIC general purpose signal content acquisitions, works fine overall.4. I can easily do a screen capture or print out of the data and send it off.5. Probes have relatively good length leed lengths, plastic should be a bit firmer.I gave this product 3 out of 5 stars for the reasons mentioned above. If your time base shows numbers in the software claiming sweep times from 1 nano second to 5000 seconds and does not live up to this in reality, then, it is not truly living up to it's functions as a true instrument for what it should be doing. The instrument should perform all of it's software and hardware rated functions as per the parameters offered to the end user for the product otherwise it is not a true representation of it's true operational functions.

Good as a low cost scope, good for most troubleshooting. Also easy to be portable, working with your laptop PC or Android phone. -all very good for the dollars! Note it's a low voltage device max 35 volts in, DC coupled only. 350V with 10x leads. I added a small capacitor between 2 BNC connectors for an inline AC coupler. The software app. as supplied on the CD does not work with Windows 10. My install sequence was: Download the app and the latest driver from the Hantek website.-You need the new driver, it has a Win10 version in it. Was a .rar file, need a .rar unzipper to extract the files, save where you can find it again. Install the app. Running it with the 6022 connected you see no trace. To find the driver you need to update, with the 6022 connected go to devices in Windows. In the USB area see unknown hardware or it may say Hantek. Open that one up, right click to get to update driver, select browse to find another on your PC, go to where you saved the driver just downloaded, and load it. Then it works.

Ni siquiera prende el Led inidicando que esta prendido

So, this is a 60-something Oscilloscope. Do not expect a professional unit.But it is great for electronics-hobbyist, to understand what is going on, to see audio signals and to test amplifiers, filters, switching power supplies, and so on...Most probably you will have to calibrate it (mine came with a 20 mV offset).Also, stable triggering is a little bit of a painForget about the SW, look for Open-hantek and download the open-sw version.This is a great unit if you mainly want to "play" and do not want to invest twice the money on a Pico unit

This is good entry level PC based scope. The probes it comes with are good quality as far as probes go and the software, although basic, seem to work well. Make sure the specs are within what you’re testing. If you’re looking for a scope for automotive diagnostics, I’d recommend spending a few more bucks and getting the Hantek 8ch automotive scope. You get a LOT more for just a little bit more money
