Excellent video Darren. I always have that thought whenever im capturing data of "have i got too much time on the screen" or "have i got enough sampling power to see what i want". I find it a balancing act that comes naturally over time as you get used to using the equipment and capturing more waveforms
i love how you make things quite simple to understand and will start viewing your other videos, as i just retired and had bought a autel scope and needed to get educated a bit!!!
Thank you so much for this video. I now know why my Snap-On scope is so terrible. Both the Verus Edge and the Zeus have a sample rate of 6 MS/s for single-channel, and 1.5 MS/s for four-channel use. I'm watching for the Pico 2405A to become available again.
Great Video Darren :) Glad to see topics like these discussed on you tube..... Being an automotive engineer myself, i have always felt there should be more videos about diagnostics using tools like oscilloscope and picoscope ! Hope to see more videos from your channel. I just had one comment on todays video, you should have also discussed about nyquist criteria for avoiding anti aliasing when selecting a sample rate.
Glad you enjoyed the video. What commodities do you look after in Automotive Engineering? Regarding the aliasing, I suppose this would be apparent on very low spec scopes on higher frequency repetitive signals; can you think of any common examples? Would be good to make a more detailed video covering this topic and being able to replicate aliasing will help get the message across. Thanks for the feedback! 👍
@@MechanicMindset My work involves control design for engines. Regarding aliasing, i am not sure how you can replicate it for demonstration on a vehicle. Generally, we see it during downsampling of very fast changing signals, one of such can be any pressure signals in the car where you would see some high frequency noise folding into the lower frequency domain.
Excellent info! Thanks so much. You mentioned in the video sometimes you might take the car on a road test. Will the pico scope actually record data for a long period of time like that? I was thinking that it would record up to 32 frames and then start recording over itself. Are there any settings I need to make so that it will record for a long period of time? Sorry if my questions are kind of dumb. I'm still relatively new to this.
No, great question! You can increase the time setting per division. So you could actually record for hours or even days. You can then zoom in after, but the quality does reduce over longer time, there are only so many samples that can be taken. Keep an eye out here, I have some PicoScope training online coming soon!
Great explanation! Thank You! Your videos have enhanced my understanding so much about these 2204 scopes. May I make a request? How about a video of when you use the drop down to choose a lead (A or B), there is a box for selecting bits. What Bit setting is best for what application?
Glad you are enjoying the video! Ok I will add it to the list. This is for vertical resolution and I do t think there are many automotive applications where we need to adjust this setting. I have played with it before, it didn’t enhance anything from what I could tell 👍
Loving the 2204A videos, Darren. The one thing that confused me was the s/div option in the software. I was always under the impression that that just changed the display output in the software itself so you could see more or less information depending on how big you want it on the screen (but the amount of information coming from the scope was the same depending on the sample rate chosen), but from the way you explained it, that actually changes how much information the scope provides to the PC as well? Like the s/div is directly linked to the sample rate?
I have a pico scope 3423 from 2007 it’s 4 channel the sampling rates are 20MS/s for one channel and 5 MS/s if using 4 channels this was a top of their range back then I bought the full kit wasn’t cheap never really used it your video has peeked my interest got it out of the box last weekend had a look at some ignition waveforms still working great downloaded the pico 6 automotive software works with that ok but I guess for the price I should really get the 2204 far superior a big leap in 14years
Awesome! I’ve not used that before. I’ve used the 4423, the first Automotive scope I think and that’s still good today. What’s the vertical resolution on yours? You might be interested in the training I’ve just launched 👍 www.mechanicmindset.com/diagnostic-coach
@@MechanicMindset 12 bit resolution will have a look at your training I attended a pico training course in 2007 when I purchased the 3423 and to be honest it was to short and to intense plus there was guys there that were already using scopes went over my head to be honest.
@@kevinpalmer7452 Cool, that’s good! 2204 is only 8bit. Might be worth hanging on to the one you have for a bit. Learn how to stretch its capability, then you will appreciate the upgrade and what the extra specs are buying you. I’m no salesman but the course I made explores all aspects of Pico 😂👍
@@MechanicMindset I know its crazy people like to take advantage of guys tryin to train and become a better Mechanic or tech there is some great content from guys like yourself on youtube a lot of crap to . thanks again
Excellent video and presentation. I don’t know your name and would like to so I can address you properly. Your videos are extremely helpful to me. You bring it down to level that anyone knew to scopes can truly grasp and understand. Thanks buddy for sharing your knowledge 😊 Artie sorry if I would of read your about info I would have known your name is Darren. Guess it pays to read. Now onto the other videos
Hi. thanks for taking the time to explain this as ive always tryed to understand it. Just one question- When sample rate is increase a lot to say 100ms and you then get more information on the captures does this then reduce the number of frames you capture or overall time??
Hi mate, sample rate doesn't affect the amount of screens that are recorded. But if you increase the time setting, you should probably increase sample rate too. it all depends on what you want to do really. If you want to zoom in, more than likely you will want to increase the sample rate
Actually, my mistake in reading the sample rate could reduce the waveform buffer. Looks like it depends on which scope you have as to how it is affected 👍
Great question, I don’t think you can directly You can change the buffer length which will spread the maximum samples over more time giving less sample rate. I’m need to do more research on Hantek but I think that’s how it works. Thanks!
I think you have still left some confusion, since at the beginning of the video you are referring to samples per second, but when you are making adjustments, the sample rate is per screen, not per second. If it was samples per second, the resolution would be the same regardless of the zoom factor of the time axis. Perhaps I don't explain it so well either, but I reckon you (Darren) know what I mean.
Yes I see what you mean; I think I was trying to explain in its simplest form. There is an added layer to this too because the sample rate changes based on your time selection and maximum desired waveform buffer; all based on the oscilloscope memory. It can get quite deep 😅. It’s made somewhat simpler in Pico 7 with the option to prioritise sample rate or waveform buffer
@@MechanicMindset the cat phone. No idea what it is but I do know I am waiting for Elon Musks pi phone. Signal from above crystal clear and not having to pay THREE mobile for their pony service. Thats a good thing. Signals not flying through us is also good. Never been a believer of radio masts
Hi, yeah I will have a look in to it. The serial decoding feature is quite simple to use. What is not so simple is obtaining the manufacturer information that can be used to decode that data in to information safe for humans 😂. I suppose that’s what the live data in diagnostic software helps us achieve. I’ll have a dig 👍
First of all great explanation 👍 Could you please tell me if it's worth buying the 2205A which is 200 msps over the 2204A? Do you think it's worth the extra money?
Hi, if you want to do lots of captures at a higher time (I.e 200ms/div) and then zoom in then yes - it would be a bit better. ‘Real time’, for example a CAN capture at 50us/div, there no real difference. If you want to spend a bit more, go for 2405A, 4 channels and specs like 4425A! 👍
Potentially yes, if you wanted to do a lot of zooming on longer recordings. Spend a little more again and you can get 2405 with 4 channels plus the extra samples 👍
Thank you sir, what do you think about an automotive oscilloscope that has 10 Mz bandwidth, 40 Ms/s sample rate to analyse can bus fast canbus, and all car's sensors. It's AVL DiTEST SCOPE 8400.
Does this tie into the buffer? I was always under the assumption that higher sample rates used more of the buffer, thus less screen recordings you could get. Is that correct?
I think there is a relationship between time base and sample rate. The scope automatically enters a slow sample mode over 200ms (this can be changed in preferences). The buffer can actually be increased to 255!
The main difference is an increased frequency & sample rate plus the option for 4 channels. Higher sample rate is better - this 2204A lacks clarity for certain tests but is great for most. Hope that helps
@@MechanicMindset What I meant was what is the purpose of having a different frequency? I see there are 5 different frequencies you can choose from. I’m going to pick up the one from your affiliate link. Great channel you have. Thanks!
@@pl5882 Ah, thanks for using the links 👍. The Pico Automotive kit is 20Mhz and 400MS/s. I reckon the 2405A looks like the Best Buy. 4 channels. 25Mhz. 500MS/s. Not sure if it is on Amazon though
Hi, you need an amp clamp that outputs a voltage signal. BNC is best, but you can get a 4mm/banana to BNC converter to use other types. The one you mention 210e doesn’t look like the correct type. Check out my links for cheap amp clamps that work 👍
So the ‘bits’ refer to the scopes ability to rise and create a smooth line (to replicate an analogue signal). Low bit rate scopes will have steps in the wave form. Hope that helps 👍
Mate I want to know something. Injectors voltage diesel renault captur when ignition is on engine off. Im reading 4.7 volts both wires. Cranking im still reading 4.7 on both wires. I thought should be 12v and cranking ground side 0 volts. Should i get 4.7 or 12v?
Hi, yes I have a video to show how although I don’t use it personally. For me it’s the same as Pico 6. You can import the probes if you wish to. Thanks for watching!
@@MechanicMindset okay, I'll look for it. I know there was one video showing how to get it to work with non "automotive" scopes, but as I recall, it seemed like something that likely wouldn't work long before pico fixed things. I saw you measure degrees, that's a big part of what I'd want. If it can make the markers for every 90 degrees, that would be do fine. Also, if you can create custom probes, that pretty much takes care of the rest.
@@tonyfremont Ah ok, you can measure degrees on the normal Pico software; no need for the Automotive version. Drag from the bottom right corner. You can download it and try it for free in demo mode 👍
@@MechanicMindset yeah, I was surprised when you showed the degrees already calculated. I was expecting you to start explaining the math for doing it by hand.
I'm waiting for u r New videos, in laptop display one option is there measurement we go that option it's tell some options like sensor, ignition, Diesel injector,cam,and Crank please kindly explain
Sorry I can’t make more! For your question, I think what you refer are ‘preset measurements’. It will set up the time & voltage for that certain component. It is a nice idea, I prefer to choose my own settings 👍
Hi, sorry if it wasn’t clear. If you increase the sample rate, you will get more clarity when zooming in over longer recordings. If it is lower, you will get the ‘triangles’
The memory spec also plays a part; it determines how many samples can be displayed. They are usually fine at fast time scales, but start flagging when you want a lot of time on the screen ie 10 seconds
I sometimes watch a video 2 or three times and I usually pick up more info this is one of those video. Basic as is maybe to some but very informative to me who never understood it's value.
@@dasouth1978 The time setting is per division. So when we set it to 200ms, that how much time is represented in each square, 10 squares on the screen left to right, so we get 2 seconds of data on the whole screen. Set it to 100ms, we get 1 second. The sample rate is separate from the time setting per division. It simply defines how many samples per second. Hope that helps
This is the most comprehensive explanation I have seen anywhere on sample rate; something many techs would do well to watch not just beginners. Very useful information. Thank you.
Glad it helps! It does get a bit more complicated when we start chains the time base and limiting the waveform buffers, but this covers the basics 👍

7:50 I guess you mean lowering the sampling rate will help taking longer recordings? The higher the sampling rate the more data is created.
Hi, sorry if it wasn’t clear. If you increase the sample rate, you will get more clarity when zooming in over longer recordings. If it is lower, you will get the ‘triangles’

Check out this video for a review on the PicoScope 2204A! ua-cam.com/video/1LBKtlpCj_4/v-deo.html
Snap on zues is 6 million samples and that pales in comparison to pico. It ok but not a clear pic
The memory spec also plays a part; it determines how many samples can be displayed. They are usually fine at fast time scales, but start flagging when you want a lot of time on the screen ie 10 seconds
I sometimes watch a video 2 or three times and I usually pick up more info this is one of those video. Basic as is maybe to some but very informative to me who never understood it's value.
@@mike-yp1uk It’s in the basics where masters are made 👌
6:40 200 miliseconds is 0.2 seconds & not 2 seconds.. Nobody spotted this after a week?
2 seconds on the whole page. 200ms/div x10 divisions = 2 seconds 👍
@@MechanicMindset so the samplke rate is per screen & not division?
@@dasouth1978 The time setting is per division. So when we set it to 200ms, that how much time is represented in each square, 10 squares on the screen left to right, so we get 2 seconds of data on the whole screen. Set it to 100ms, we get 1 second. The sample rate is separate from the time setting per division. It simply defines how many samples per second. Hope that helps
