Here, let me fix that link:

http://whites.sdsmt.edu/classes/ee320/labs/XYZs_of_Scopes.pdf

Actually the course documentation is quite nice, although homework, exams and labs are not linked:

http://whites.sdsmt.edu/classes/ee320/


In any event, the one I linked is updated, maybe for better or for worse, some material seems to be gone but other material was added.

Sorry to the rest for getting temporary OT.

@ez24,

Not sure what you are doing when inserting urls, you just need to type it and the forum will convert it to the right thing.

Your link is probably hand edited and is doing this:
Code: [Select]
[url=http://[url]http://whites.sdsmt.edu/classes/ee320/]
[url]http://whites.sdsmt.edu/classes/ee320/[/url][/url]

Instead of this:
Code: [Select]
[url=http://whites.sdsmt.edu/classes/ee320/]http://whites.sdsmt.edu/classes/ee320/[/url]

And they are not clickable the way you are doing it, just type the url like this:
Code: [Select]
http://whites.sdsmt.edu/classes/ee320/

And the forum software will format it right for you.

Edit: Works!  why is there a "link" button - 2nd from right 2nd row  -  looks like a page over the globe ??

thanks for the advice  (I thought it was because I used a 4 letter word once)

Another thing - in Preview my old links work - again thanks

This topics has been covered in a few different videos, but is requested so often by my channel subscribers that I put a dedicated video together.  It reviews and demonstrates why properly compensating your 10x probes to *your* scope is so important, and why a probe with a much higher BW than your scope might not be suitable (and can lead to a poorer frequency response than a lower BW probe).

Rather than generic o-scope tutorials (which have their place), where can I find a good Noob tutorial on the DS1054Z scope specifically?  You know, something which covers all about it, but from a noob perspective.  Is there such a thing?

Regardless, I *am* grateful to those who posted the more generic videos, as at the moment that may be all there is.

I second this.   In some of Dave's videos I cannot see his right hand (the controls).  Since this scope is so popular seems like a good Noob tutorial on the DS1054Z would be a hit.   I would like to see one that covers all the features.

So lets cross our fingers.

Buy this Demo Trainer Board:

http://www.tequipment.net/Rigol/DS6000-DK/Analog-Demo-Board/?b=y&v=7906

Or at least go through the manual:

http://www.tequipment.net/assets/1/26/DS6000DemoBoard_UserGuide_EN.pdf

And/or the demo guide:

http://www.tequipment.net/assets/1/26/DSDemoGuide_022014.pdf



I think for those that make YT money - this would be a good idea to use on YT videos using the DS1054Z

Thank you so much for all your videos which are extremely informative. Your choices of what things to cover are really good.

Is there any one in the uk that has an old scope they might donate to me I could probably stretch to spending about 50 pound depending where it is at I would be so grateful I am a welder fabricator by trade so if any swaps could be done would nice pls contact me

Has any one got an old scope they would donate or sell I could afford around 50 pounds I'm in as Dave says the old dart England I would be so grateful I'm a welder by trade so pos I could do a trade if you want anything making

I recently delivered a presentation to the NJ Antique Radio Club that reviewed how to use an analog oscilloscope, and then showed how to use the scope to view the signals inside a classic "all american five" type of tube/valve AM radio.  Please note that the audio is not perfect - there is a "demonstrator" radio playing in the background, but it isn't too obtrusive.  The first 50 minutes is the "short version" of the class that led off this thread, and the last 30 minutes is looking at signals inside the demonstrator radio.

HI w2aew,

I tried to apply your video on 2 different frequency signal measurement on a DSO but "failed".
I'm using a Rigol SDG-2042x to create the 15Mhz and 1.5Khz signal to a Rigol DS1054Z. Whatever acquisition I choose from it's either displaying the correct frequency of the lower one or the higher one when adjusting time-base of course. Can it be that this Rigol just calculates the frequency based upon the screen result and not the memory?

It certainly sounds like the sample rate of the waveform data isn't sufficient for both input frequencies simultaneously.  This is either because the measurements are made on the displayed points and not the acquired points, or that the acquired points don't have sufficient sample rate at the slow timescale settings.  I don't know if the memory/acquisition settings in the Rigol give you the ability to change this or not, I've never used one before.

Hey, I understand your comment and remote observations. I did try to tweak the settings on the scope but without any resolve. I can change the acquisition settings but the on-screen frequency display just is not correct... hmmm

Aha.... I found there is a Frequency Counter, not a soft-menu item from the whole selection, which you can switch on and then reveals the frequency on the top-left hand corner. This is then Spot-On!!!  :) :) :) :)

Very nice, I like the alternate take though. (at the other club, easier to see and hear, though the guy mumbling near the mic was off-putting[just a personal annoyance])
Now I need some digital scope education, like how much storage should i look for for practical use cases, and what to do with bus-interpreter features(I2C, can, etc)

Deep memory mainly becomes an issue when you need long term captures of high frequency signals, where you need both long waveform times and high sample rate. How often do you need that? Depends on what you do. The scope on my bench has 20M record length. Most of the time I have it set to 10k record length. Occasionally I'll dial it up to 100k or 1M, but this is rare.

As for bus decode and triggering, this depends on what you're working with, and if you need to see the decode on your scope or have a need to trigger on a specific command. Note that there are inexpensive digital logic analyzers that can do decode on these various busses too.

The good news is that the luxuries of deep memory and bus decode/triggering are available in scopes and instruments that won't completely break the bank anymore.

Another thank you note from someone who has (I think...) watched every video you've made -- thanks Alan!

I'm in the software biz, but (a long time ago) they did teach me electronics as an undergrad -- including using a 20 MHz single-trace scope with all lettering in cyrillic. I wish I'd paid more attention back then... youth is wasted on the young!

Anyway I found your channel with your excellent video on I-Q signals and mixing. Another great video -- all of your videos are excellent, not just the scope ones. Keep up the good work!
Returning to electronics after a 25 year break.
