Thanks Eddie. I have the 924S version of this scope. I just used it to check a motor drive board I built and its portability was great because I'm working with a tricky 65 lb., 8 hp brushed motor so it was tough to drag it around. I like it, I've had it about a year as my backup scope. It's not really important when a video comes out. Maybe someone is just thinking about this scope so they do a search. Well maybe yours was the first or last, it still adds to the info people are looking for. Hope your ankle is better.
This video is welcome, even if delayed. On the scope comparison video even just the paper numbers are fun, but actually seeing the scopes in action is even better. P.S. I own the 924S which is the top of the line in this series of Rigol scopes. It includes a signal generator and can do a Bode plot. I love its best vertical resolution of 0.2mv/div (at 12 bits!). I do wish it sampled a bit faster, like the rival Siglent's 2GSa/s, but in truth for my audio electronics I don't really need that.
Great review and summed up nicely. I personally own Rigol products and find the value exceptional. The price for performance is excellent, and the reliability has been excellent as well.
@@MrDoneboy Great scope! Unfortunately when I started I didn't have the money. Now that these modern scopes are here (of which I have one) buying an old analog one would just be for nostalgic reasons. Would I ever use it for real? ;-)
Thanks for the video ... Just recently bought this scope and would consider myself just above a 'novice' LOL . I agree that an 8 inch screen would help plus I find the display to be a bit dim ... I'm sure my 62yr old eyes don't help . The USB powering was a big selling point for me . Over all I am happy with my purchase . Looking forward to a more extensive hands on review .
Thanks for this great feedback!! What about the USB power made you like that? Was it for the isolation from Ground? Is there anything in particular that you would like me to show in the review?
@@KissAnalog I like the isolation and the portability with possibly using a PD source. One less thing to worry about with safety or destroying something . Just seeing someone with more experience than me getting around the features of the scope is something I always keep my eyes out for . Mostly using it for hobby electronic repairs and troubleshooting and education . Thanks again .
I have a DHO804 and really like it. Nice score Eddy. * I saw there is a fella out there that designed a battery pcb that uses the vesa mount and completely isolates the scope! Also, with the right adaptor and a keyboard you can get the wifi working!
Here are my gripes with this scope: 1 - It's two times louder than my two computers, so I wan't to turn it off, but then 2 - it takes almost 1 minute to boot, so I have to keep it on. 3 - it gets a bit hot 4 - 12 bits doesn't help much when zooming-in a stopped waveform. You can zoom in the centre, but close to the top/bottom edge it simply clips the image even thought it already has the undistorted samples. You have to stretch the time base forth and back to get it unclip the image. 5 - single trigger in 1s/div setting hardly ever triggers. It has a huge time window in which you can't trigger it, and you can't know when. 6 - Two extra knobs, are often assigned a function that is already covered by other knobs, instead of helping you to adjust more settings faster. 7 - Trigger threshold/sensitivity is not adjustable. If a signal gets smaller than 1/2 of a division, it doesn't trigger anymore though there is plenty of resolution left. 8 - A bit slow responsiveness together with a bit too small screen, doesn't make it fun to use, despite a very nice sturdy design of the case. I didn't use this scope long enough to know, if I could get used to it, or if it would get frustrating to use by a beginner. I'm still using DS1052E for most measurements, it turns on fast, and it is quiet enough (I've replaced a fan) to keep it turned on.
Never too late...I'm still trying to catch up...at 71, I'm afraid I don't have enough time to catch it all :) About a year ago, at your recommendation, I bought the Pico 2206B MSO. Really not a winner in my book, yeah usable but the selection/menu system seems to have been designed by engineers who have never used a scope and have no idea of usability. It also suffers from what I consider a poor display...after years of looking at CRT scopes the LED screen of a computer just doesn't react the same way phosphor does when scanned with an electron beam. (The jaggies on the trace drive me f'ing bananas!) So I have almost decided to part ways with the Pico and move on to something more integrated that looks like a traditional scope and the Rigol with 12 bit input may be the thing. Of course, it too seems to suffer with endless menus and usability issues but at least it has front panel controls for the commonly used controls...input sensitivity, time base, and trigger. Thanks for the look at the scope.
Thanks for this feedback! You are right - the CRT (analog) scope screens from Tektronix and HP were pretty nice - but there was no way to save those waveforms except to take a Polaroid :) Building those CRTs was an art and expensive - so those days are gone. I think the Pico is nice as you can use the larger screen on your laptop or monitor. The screens today are much nicer and I have gotten very use to them. I like the manipulation of the capture rates and such that make analyzing signals so much better today. The Rigol or any bench scope will look like an old bench scope albeit lighter and not near as deep;) But the screen is still going to be an LCD type - but just smaller (7" in the case of this new Rigol).
When first switched on the DHO914 that I have smelt like hot electronics. The smell has mostly gone away. I measured the heatsink temperature using a thermcouple just resting against the fins (the holes in the back are a little too small to allow my surface probe to go through). The measurement was 36 degrees C in an ambient of 24 degrees C. So allowing for poor thermal conductivity between the heatsink and the thermocouple the temperature doesn't seem excessive. Possibly there is something else that is getting hot or perhaps it is out gassing of thermal gap pads causing the smell. I don't know.
Thanks for this feedback. I have heard that this has been a cause for concern - at least at first. It might be as you say - something that is just out gassing when new. This is a loaner - so the smell has gone away - if there was any. The fins of the heatsink have the fan on them, so you'd have to go to the other side to see a higher temp. But your measurement would seem to indicate that the heatsink is doing its job;) If it were too hot - say 30 degrees above ambient - then they would seem too small.
Yes - the size and DC power makes it more portable. However, a battery operated scope with larger screen like this one would make more sense I think: ua-cam.com/video/bFWJUmgs_8M/v-deo.html
Hi dude. Like many videos before, this is also great. My work is mainly related to the design and repair of audio devices, as well as electronic musical instruments. For now, I'm using an older analog Hammeg oscilloscope. For most jobs, it is sufficient, but I lack more precise measurements and some analyses, such as frequencies, bandwidth or distortions. It's a shame that there is no function generator and bodeplot. I also like that it has a separate grounding, so it can be used for switching the power supply without an isolation transformer. Do you think this Rigol is good enough for that purpose?
Have you tested any oscilloscopes that use an iPad as the display? I am looking for a small, portable, somewhat ruggedized o-scope for use in the field that will use an iPad as the display.
Great question! I think Picoscope is awesome as a USB scope, but one that works wireless on your ipad - Micsig is the best I've seen: ua-cam.com/video/bFWJUmgs_8M/v-deo.html
Power pack is "USB C standard". The scope runs on 12V. Can the USB power pack be plugged onto a mobile phone to then automatically deliver only 5V instead of 12V, or will it blow up the phone with 12V?
Title under video is wrong. This is not DHO812, this is DHO814 which have 4 channels. DHO802 and DHO812 have two channels. The best choice to buy is DHO804 with 70 MHz bandwith but with easy hack he can extend capability to 100 MHz like DHO814 scope and from 25 Mpts memory depth to 50 Mpts memory depth like DHO9xx series scope models have.
Thanks for catching that! Also, thanks for pointing out the hacks. I don't know how I feel about myself telling people about that. I think a person is OK doing whatever they want to do with something that is paid for, but I don't know if I should advertise that myself;)
@@KissAnalog Love your videos. I can't get over the fantastic oscilloscopes they have now days.....and relatively affordable. When I was in school we used a Tektronix 2235 and a newer model that I forget the number of. They were great but these new ones are just fantastic. Thanks for showing us models we might never see otherwise.
@@KissAnalog You need to turn Fine OFF then push the zero offset button and all will work as you will expect. At 24:29 you did just that had the Fine OFF and pushed to zero but then did not try to move the trace to see that it works correctly until after the calibration. Calibration has nothing to do with that problem. The step is 20mV so if you start from zero offset you will be able to set it to 1.50V and you can do 1.48V but you can not do 1.49V (what the auto set it to as that was the exact middle of the signal) unless you set it to Fine ON.
I did try that several times thinking that maybe I did the wrong sequence, but to no avail. I edited this out as I played with it for several minutes thinking that I just had it off grid using the fine adjustment. I tried the same on the second channel and it worked as expected. Maybe it was a fluke - but the cal is the only way I could get it back on grid.
With you not having a clue how that scope works, your review is impossible to follow and know anything about it. Apparently your not familiar with it at all. You would’ve benefited yourself and us, by doing some studying on it before just throwing it out without thought.

Hi Eddie, great video and amazing tutoring. Thank you so much.
Glad you liked it!
These scope are getting nicer and nicer. Remember the time we only had the trace on an analog scope to work with?
Yes, but my old Tek 2245A still kicks it!
I do remember that:) They have come a long way;)
When you have a tool that works - why change;)

USB-C PD Is multi-voltage/multi-current.
So it can work with all sorts of devices. Legacy USB was fixed at 5V
Great question. It seems that this power adapter does seem to be set to negotiate what voltage is wanted by the device.
My preference is a physically deeper, and heavier scope. It's annoying to reach up to a scope to connect a probe, and the scope "walks" away from you.
Thanks for this feedback! I think others might feel that way too. Some will like the compactness.
For me the compactness is a plus, I want to hang it using a VESA mount. Shouldn't walk away in that mode...

Sorry - this was just a box opening and first impressions. I'll see how the HDMI works when I do a full review.
Nothing to do with calibration the Fine needs to be OFF.
