- Dave answers a beginner forum question on why the Rigol DS1054Z oscilloscope does not show the intended vertical Volts/Div setting he expects.
A trap for young and old players alike.
1X and 10X probes, and auto probe interfaces.

I have been watching your videos for almost 3 years now. I'm happy to report that not only I understand most things being talked about in the videos, I also know them thanks to you Dave. Thank you for your service to the community.
thekaduu Glad to hear, thanks for the support.
EEVblog now thanks to you I speak Australian.
Dave, I loved the video editing where the link and preview to the other videos were on the screen of the scope. Little details like that are what makes your channel top notch.
Nice touch with the video editing, showing the older videos "playing" on the oscilloscope screen!
EEVblog Just fixed my first "bad cap" monitor. So proud of myself! Thanks for the great instructional videos, Dave! :)
The editing quality of this video jumped out at me, it was very pleasant to watch. Reminiscent of one of those old school-room videos about scopes.
FFcossag I've actually changed something subtle in the rendering. Motion should be sharper.
To make it easier to notice that the switch on the probe is one way or the other simply use a marker and place a dot on one side of that recess where switch is. That way if the switch is moved one way it will cover up that dot, while when it is the other way that dot will be visible.
thank you for really taking the time to explain everything with much detail for us who arent familar )))
Thanks mate, Great video as always
Loved it. Im going to get some better probes also, Thanks.
Good stuff, cheers!
Nice video. The number of times I have been fault finding and checking voltages only to find I have X10 selected.
Just got mine today! Already falling in love with it. Considering I was coming from a donated Analog Hung Chang 20Mhz Scope thats considerably older than me, it's a breath of fresh air.
Sir Why Ah, the old Hung Chang! The college lab scope of choice back in late 80's...
Thanks Dave
No annotations but its in the video details. Great vid.
On the MDO3000, the compensation data is unique per channel and probe combination. If you move a probe from channel 1 over to channel 2 for the first time it's not going to be compensated. You need to perform the autocompensation once for every channel/probe combination.
thanks Dave !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
excellent video, great explanation, can you do more videos on how to use the various features on that Rigol DS1054Z scope. thanks mike
Thanks
Nice Piezo electric effect at 10:30!
Steven G I've got a video on that! ua-cam.com/video/KFCRB4d991E/v-deo.html
That bugger caught me out when I bought my DS1054Z because, it defaults to 10x which is weird, but even after setting it to 1x, it always changed back to 10x and caught me out again, because again, by default, the scope is set to restore factory defaults every time you power on the scope, so you probably want to change that option as well
arcadeuk Are you sure it defaults back to 10X every time it boots? That sounds wrong.
I can confirm after testing, that it does default to 10x, if you have the scope set to reset settings on power on
Dave, you forgot to add annotations.
Arnoldas Sarnauskas Damn!
I have a 4 million year old cossor scope, no fancy settings, just remember the 10 million ohm probe is on :-)
Setting a probe to x10 means that you have to multiply by 10 the readout because the probe attenuates the measured signal by 20dB before feeding it to the scope.
ppdan Not unless you set the software to 10X in which case you don't have to do the math it does it for you.
I always wondered why "cheap" scopes without the "auto sense" don't permanently display the multiplier on screen.
For example on the Rigol DS1054Z there is enough room in the bottom bar to show the "x10" or whatever setting next to the "V/div".
Even experienced users can sometimes be fooled by this, although it'll probably only last a few seconds (has happened to me : "why is that reading so high ... aw yes, nevermind")
woaaa you got youtube on the rigol screen :O @9:30
Dave please design a differential probe or suggest a open source one for low frequncy usage, they so dam expensive.
Good video!
***** Use two probes, subtract one channel from the other. Poor mans diff probe.
EEVblog Lots of differebtial isolation devices will help back you up on that. The energy harvesting bias supply for getting the measurement domain centered on 0 then becomes the bigger challenge...that or testing one's coax bonding for EMI rejection.
EEVblog Doesn't look like much exist, kickstarter anyone?
***** THAT...would be really useful. Many options come to mind.
Mrpsychotehpyro Imagine the possibilities! freaking hell ! c'mon people someone out there? do it! do it! you can do it!
At the end of the clip it looks like audio from the mic or it's radio on the scope.
Lucky me that on my probes they warned me to check that the scope is in sync.
You might point out that some scopes read the probe and automatically when the gain on the probe is changed.
Andy Bushnell I spoke before I heard the whole video.
On the right to the timescale knob. Use the Force button :)
pvc988 Only for people named Luke.
Dave thanks for the tip as I notice that and sure enough set the probe Bingo done deal lol Question Dave I need to know HOW to set my view calulations , FREQ,Vpp,Avg on the screen at the bottom so they will be there at startup ..Yes I have the DS1054Z You can email the answer if you wish . 73's
Hating the switch on the cheaper probes, you have always one probe lying somewhere with the wimpy switch accidentally set to 1X and you wonder why your values are off.
Can't click on the videos you're talking about at the end. No link.
Hi Dave, i'm a recent subscriber and am loving your channel. Do you have a video that covers "servicing / inspecting" electronic items?...perhaps when one has just bought a secondhand item and want's to clean / inspect the item for peace of mind before putting it into full time use....many thanks for a great channel.
Ian Muggeridge Not in the general sense, no. It's going to be quite specific to the type of product.
interesentingly the DS1052E shows "volts/div at limit" when i try to zoom in "too much". this is more describing than the generic message "parameter limited".
maybe the software developers favored this generic message cause it easier to implement and thinking "well an engineer knows what this means"
Yeah, if you don't know what knob you're turning, you shouldn't be touching expensive equipment.
please based on your knowledge which one should i buy the hantek DSO4102C or the rigol DS1102Z
Hi Dave,
How does this Rigol DS1054Z compare to the New . . .
GW Instek GDS-1054B Digital Storage Oscilloscope, 4-Channel, 1 GSa/s Maximum Sampling Rate, 50 MHz, 10M Maximum Memory Depth for Each Channel ?
Really appreciate your reviews & tech knowledge !
I have a rigol 1052, how accurately does it measure voltage?
SirArghPirate As good what the datasheet spec says. Scopes are usually only a few percent accurate.
Good for price
Can I measure AC voltage of 230 Volt RMS with this rigol oscilloscope, thank you
+EEVblog Hey I just got to Australia :) took 55 hours :(
Are you in adalaide or sydney
Yepp :) because they not give You a nice decent 1:1 probe! They just packed 1:10 cheap. Because of the frequency bandwith lower on cheap 1:1 probes.
Wouldn't it be possible to actually see the noise on an analog oscilloscope with a high speed camera? Would probably make for some interesting footage
masat87 I tried that in one of videos using a long exposure.
masat87 Lol, you should probably watch the video he linked to where he does exactly that...
masat87 Probably not. Chances are that the analog signal processing system will aready limit the bandwith in a way that prevents most of the noise from ever reachign the screen. Additionally - the phosphor of the screen is usually of a type that exhibits a considerable afterglow - therefore any fast noise that was not caught by the electronics will be integrated into a slight halo around the trace, but not distinct patterns....it is an optical low pass, if you will, designed to present a more readable trace from a slow or erratically moving beam
TheHue's SciTech I watched that (although a while back), but the effect of the long exposure was different from what I imagined for the high speed camera.
How does that 1GHz probe get power internal battery or some kind of circuitry that takes the power off that 1 connector
Jeremiah Lowe It doesn't need power, it's just a regular "passive" probe. Only "active" probes need power. 1GHz is as high as passive probes 10X divider probes can go.
Didnt know that Im a beginner just got my first scope 3 days ago from a college its an old AN/USM-281 unbranded analog scope the guys at Morehead college gave it to me
Rigol VS Tektronix... It is really funny.
ok dave what prob would you use for a cheap oscilloscope
trigg99 The one that comes with it.
what is my problem, I measure a signal with 21 volts, but when I want to take a closer look, the message Parameter limited comes up. 20 volts is the end and the signal is not visible. Vertical parameters limited. what am I doing wrong? Signal is only visible in Auto mode and at 5V per division. Can someone help me?
Включи делитель на щупе
I am trying to see an intermittent signal (such as me touching and untouching a test point) and can't figure out how to do it. I want the scope to show 0v as a line across the screen, but when i very briefly tap the oscope probe to 12v, it shows the jump and then goes back to showing the 0v line when not touching. I want to see a jump that remains after my brief touch is not touching anymore. So like if I touch 12v 5 times in 10 seconds, i will see the 0v line interrupted by 5 brief 12v spikes.
But I have tried for what seems like an eternity of trigger options, run/stop,auto set, normal set (auto set turned off), sec/div, and I don't remember what else. No luck.
I can get it set so the line jumps to 12v, but as soon as I disconnect it, the line goes back to 0v. No history. Can someone explain to me how to do this. I have a 2 channel DOS (Hantek DSO5072P).
Wish i could find a cheap analog oscilloscope... been hunting on ebay for about 5 months and haven't been lucky yet.
course unfortunately have a limited budget due to being disabled.
been keeping eye out on Tek 2215 2225 analog scopes for basic circuit testing.
qoaa I think sellers are asking too much for them. I bought 2 Hitachi scopes from eay, expect to pay around $100 for a 60MHZ scope. I have a V-650F.
Try to buy one that is shown powered on with a trace showing. Most sellers don't know how to test them so they usually list them as is.
Bri G. thanks!
I do have a mentor, he's a retired air force, and has masters in electronic engineering. He's been helping me as I run into questions, problems, confusion. I have a good multimeter, but he says I need an analog scope. That I should start with an analog and so I can see what my build is really doing, and learning about phases, 90/180 out of phase situations.
He's a fan of Tektronix and for a beginner he recommended either 2215 or 2225 to save money but his advice is don't go over $100 for those 2 models.
He deliberately wants me to stay analog and simple as I'm a novice. I'm a ham operator so I knew the basic equations, but now I'm putting it into practice and also have books home studying theory.
Thanks for reply, it does seem many scopes on eBay are overpriced. One listing I laughed, a guy said he got scope free from store that went out of business that was gonna dumpster it. He knew nothing of it, it was a tek 2215, it powered on but no probes, as is starting bid $300. I was like wtf?! :-P
qoaa I have 2 Hitachi scopes, was going to give one away, it's old but works really well, will include a probe with it. All you have to do is pay for shipping.

tim a Retractable hook tip
my Rigol DS1054z 00.04.03 sp1 board 0.1.1 its one week old, 2-4 2016
i have used all the web generators i can find, nothing wokrs, do the scope have to set up first? anything on the motherboard needs changed? it my scope too new for the hack to work? any help would be appreciate
thanks
Randie
interesting.. lol, I've been doing the division in my head, didn't know there was a software function to do it for you. doh! >.
EvilPlagueDoctor There you go!
what is an oscilloscope even used for? I'm just starting out in electronics and i could use some help.
+HalfSpeedMastering thanks for the help.
Guys, silly question, and I know the answer is probably 'no', but can the multi-function knob on the Rigol 1052e be changed so that turning it clockwise scrolls DOWN the menu options instead of up? I keep turning the knob the wrong way when going up and down in the menus... I'd like to reverse it cos it seems backwards to me. Thanks.
ForViewingOnly No option to customise the controls like that.
ForViewingOnly Hmm, clockwise is typically thought as UP, and counter clockwise as down.
EEVblog OK, thanks Dave.
Richard Smith Yeah, I think my brain is just having problems with this on the scope. This is the only device I own where a rotary knob is used to go up and down a menu!
ForViewingOnly I'm dyslexic, so I never know the right way instinctively, and have to refer to my dominate hand everytime, so I can understand how frustrating that might be if its opposite of your expectations though :)
Slovakia!
Thats all i have to say
This is not exactly related to this video, that I enjoyed much, but a question I have for you EEV is:
What is your suggestion for a voltage generator (or combination of devices) that generates Low to high frequency voltage of different wave types like Sine/Square/...and so on, (up to 1GHz or more) sufficiently variable up to 600-W output max 120-V and 5-A ? ...Thanks for all your videos.
second!
well the video could happily end at 2min mark
I would not like to probe 1kV...
nice job de wb8idy
