If there were Golden Globe awards for KZfaq content then this video would be my nomination. This channel is a treasure chest of concise and pertinent information delivered in the most professional and informative way possible. Many thanks to Mr Alan Wolke from the U.K.

Just got an analog scope as a gift from my school since they were throwing It away really helpful video

This is one of the most concise and accurate explanations I've seen of these triggering features. I'm sending this to people who didn't have such good teachers.

5 year engineering degree, and I am just learning how oscilloscopes work now.... THANK YOU

I've had my 2246 for a while now and just twisted knobs and pushed buttons until the scope gave me a stable signal. Now I can twist knobs and push buttons with more confidence. Thanks so much for the time you put in these videos.

Been using 'scopes for years and always wondered what the trigger AC/DC coupling was about. Thank you so much. I missed a few lectures back there somewhere in the mists of time. Really appreciate this channel.

Man, that is one CLEAN old Tek!

Now that I have a working 465 scope I had to watch this video again. Very helpful at learning those trigger controls.

I just found this tutorial and I had just recently purchased an Oscope on eBay. The scope has these controls which I did not know how to use until now. Thanks for sharing your knowledge!

Again, another exemplary refresher. Thanks! Tom

Thanks for making this. I was playing with these controls the other day. Looking at the decay of a hand clap through a condenser mic. It's amazing how slow the time domain had to be set to see the whole thing. I'm learning much from you!

Absolutely great video. Never understood triggering so clearly.

I never understood what the "hold" function did on my Philips scope. Perfect way to explain it. Thank you!

Well done video, and gained some new knowledge about triggering. Thanks.

Excellent tutorial on the triggering functions. I'm going to go watch the rest of your scope videos now, as I'm reaquainting myself with a scope after being away from EE too long. I picked up an '87 2225 off eBay and I'm hooked!

Same here done all the labs during Electrical & Electronic Eng degree course and forgot how triggering works! Thanks for this great explanation

WOW thanks alot i been searching all over the internet for this!!!!. got my first oscilloscope an old trio kenwood 15mhz!!!, was fiddling around without knowing much.., after watching this it all makes sense thank you!!!!!!!!!

Best advanced tutorial! Awesome!

Great video! I had a tektronix 2246a giving to me by my uncle and I'm trying to figure this thing out... Your video helped a lot! Thanks

Well done. Good presentation. Thanks for sharing.

This video gave me a good idea on how the triger controls work on my tek 2245 Thank you

Thank you for all your scope vids.

As a complete 'scope newbie, this was absolutely invaluable. Thanks very much indeed.

Thanks you have the best vidoe out there. great job.

Very informative tutorial. Thanks !

Thank you very much for this! I recently saved a really sweet Tek 7904 from someone's basement and am trying to learn how to use it properly, and (coming from no EE background whatsoever) this is super helpful and explains a lot for me.

Very very interesting video, really useful

Electrical Engineers Make The BEST TEACHERS when it comes to Learning Electronics!!! I Should Know,,All I had Was Electrical Engineers Teach Me Electronics at College, They have an uncanny ability to teach at all Levels!! Thank You Alan for teaching at such a easy to understand level!!!

This is very helpfull. You sound very intelligent and made alot of sense. Thank you very much.

Another Great Video,,,,Thanks Alan!!!!

Yes. This (among others you have) was the best scope tutorial I have ever seen as well. I would love a copy of the "Scopes for Dopes" video. I have thought I knew how to use a scope for about 12 years, but of course there is a veritable inifinity of measurements that can be made, that I have yet to learn how to make. Best 73.

I just picked up a 466, my first analogue 'storage' Tek. This video is really helpful, my other scope is a basic model that does not have all these features.

excellent material, thank you for that.

Thank you for the video, really useful!

i really appreciate you going into the details about the different types of triggering. I was having a really hard time figuring out why I couldn't get 1 Hz waves to show up on my scope. I really appreciate you spelling out the 'low frequency' cutoff for the AC triggering. (Tektronix 2225)

Thank you for sharing your experience with a CRT scope. While I do have and use digital scopes, it's important to me to still practice the foundational understanding of measurements. Your video helped me to better understand the various control aspects that I was not clear on, as well as (couple) the functions of the digital models.

Great Video! Thank you so much! I'm happy I can apply this to my digital scope: I got the same controls :)

Awesome video. Thanks again

Good review of the basic controls.

Great Alan, Another well explain scope controls, Even I may know what they are it was good to hear them again and pickup refresh The old memory lol.Your very easy to understand and very explainable to what you mean , and of course showing is even Better Trig Hold Learn . Good Job Alan Tks 73's dale

Great video sir

Excellent video and very helpful Thanks.

Great video Thank you very much

Very clear and helpful, just got a rehabbed and calibrated 2465 in the shop.

Love it just got a similar scope today it is a tektronix 465m ocillscope so far I like it

This, and the part about delayed timebase, taught me so much about using my ancient 454a, without having to work through the several hundred pages of instruction manual :)

damn, I wish the scope I use at work was that clean!!! Great vid man, vary well explained.

Well explained, thanks!

That was really helpful. Thanks.

Another great compact pracktical video for the young(old) players.

Definitely thumbs up, thanks!

Very Clear. Thank you

Interesting and applicable

Thank you very much !

Good tutorial!

@w2aew oh yes! I've always been curious about practical real-world applications of the x-y function on the timebase knob. I saw some in your other videos - but more demos please. Also, the rear of my 2465A have ch2 sig out, A gate out, step/auto ext switch, B gate out and ext. Z axis IN. These are a mystery to me. Would love vids about these! thx.

Thankx mahn!! really helpfull....

Thank you!

@w2aew ohhhhhhhh. Thanks! (I screwed around with knobs and stuff and fiked my trace). Also, knowing what BW limit does will come in really handy, I've needed that feature before and didn't know I had it.

Nice. Im in my first year of EE and my first lab is on the oscilloscopeBK Precision 2121

@w2aew Watched the Basics video. Pleased to finally meet you, Mr. Wolke!

Best tutorial ever. If you ever make a Osciloscopes for Dummys DVD consider me a buyer

I love your videos and review them regularly. I was wondering if you have, or have ever used the Heathkit curve tracer. I would really like to see a video of that. Bob

On the tektronix 465, is it normal for the trace to be pretty thick? (like about 3mm). Also, what does the astigmatism knob do?

The time center button is closed and the T = 2 us. The trigger is set at automatic. I setted the coupling to ch1 instead of normal and I got a steady trigger. Thanks for your answer.

@w2aew sorry, (I'm a n00b) but what does the BW limit do? (I have been wondering that for a while now

Nicely done! 73...

Thank you thank you thank you

High end digital scopes have special triggering functions like to trigger on specific events like glitches, especific widths periods, intervals,logic patterns, etc, besides Yokogawas do you know of any other analog scope that can do that?

Seems my old Tektronix 468 may have finally reached its end of days. I've had some minor issues with the buttons and knobs for the past year or so, but nothing insurmountable. Yesterday however, the old workhorse refused to boot-up. The fan came on, and the "beam find" dot indicates the CRT screen is working... but otherwise it appears dead. Any suggestions for a quick fix before I inter this fine machine in the oscilloscope grave yard? Could it just be a blown fuse or something? I apologize for my ignorance. I'm not really knowledgeable enough to attempt a proper diagnoses. Kinda feel like five-year old kid with a flat tire.

When using the Oscope ch#1 to measure waveforms on the circuit under test, mostly the probe will use the frequency of the waveform as the trigger? What other frequencies or pulse waveforms can you use as a trigger for circuits under test? For digital circuits in order for the oscilloscope to be in sync you have to use the clock frequency as the trigger. I'm not sure what other types of circuits under test would use different frequencies/waveforms or pulse waveforms in order for the oscilloscope to display stable waveforms. Can you think of what type of applications of circuits that use different triggering frequencies that the oscilloscope don't sync up unless you use the external trigger.

Excellent video - I always learn something new about using my scope. 73 de Mike N5JKY

very good just bought a used 466 textronix

THANKS VERY MUCH

This was super helpful. My Tek 5440 has lost its trigger function on the 5B42 timebase and diagnosing it seems impossible without at least understanding how and why each of the trigger controls work. Now if you could just guide me the my diagnosis too!

Thanks!

I don't know the first thing about O'copes but I found your video very interesting and informative. I want to learn how to operate one. Does it take a long time to learn how to use one? There is one for sale just like the one on your video and I am interested in buying it. And hopefully I can learn how to use it so I can find out the problems on my stereo and reel to reels, one has the right channel that is out and the other does not record.Cheers/Rob

Thinking about picking up a isolation transformer after seeing Dave Jones pointing out potential pitfalls of not using one. What do you think? In a previous comment your response gave me the impression that you rarely use one. I understand what a iso transformer does and how it works, I am just curious if you think its worth getting one to protect both yourself and your scope? Thanks, Ken

@w2aew Thanks. By the way, what are your thoughts on the job market for EEs now and the income they make ? I had a dilemma to study to be either EE or a ChemEng. But i chose this because of the wide span of options it has to offer.

Thanks, nice video. I have a Tek 453 here that I am trying to learn how to use. Checking alignment on a signal generator soon. 73 Paul AA1SU

thank you

Do u have any videos on using single sweep and average mode simultaneously?

So if I understand correctly, what your saying is if both the scope and DUT (both grounded with a 3 prong plug) are plugged into the same grounded power strip for example, an isolation transformer is not needed because both are connected to a common ground?

thanks a lot

Dear Sir, I have an analog Tektronix scope 465 facing problem. I want sent you the screenshot of the scope to guess the problem from which section. Is there any possibility to send you the picture of the screen? Or any other option. Thanks in advance

Awesome vid. Though, I'm confused as to why I'd use NORM triggering when displaying both channels in CHOP or ALT mode. Just picking whichever channel is being displayed at that time seems like it would just make the triggering random.

i have mine looking at 12.6V from a step down transformer hooked up to 120V (wall outlet) but its not a perfect sine wave. when i switch to measure the signal coming from the wall, its not a perfect sine wave either, what could be wrong?

Does the Owon SDS7102 or another new oscilloscope facilitate the triggering process?

This machine is ready for museum

Hi, I have a question on the grounding schemes in scopes. In case of an Analog scope is the scope ground connected to the safety ground? So if we try to measure an isolated load (without safety ground connection), is the load being grounded via the scope? I have many follow up questions related to the isolated scope and isolated probes etc. Would be great to see a video on this topic if you dont mind. I came across a webinar from Teledyne lecroy "Probing in Power Electronics What to Use and Why". They mentioned it is not safe to use passive probes in many applications.

enjoyed the video. I have the Tektronix 465B and I am in the process of calibrating it. The manual specifies the use of a time mark generator specifically the Tektronix 184. These are almost impossible to get hold of here in the UK, do you know a modern equivalent that I could use?any help from anybody would be greatly appreciated.

I just came across your video series and I love them. I do have a question and it has to do with, in some videos where you are scoping small signals there’s an complete absence of high freq fuzz and genuine high freq interference, spikes, bursts and misc spuria flying through your scope’s display (i.e. cellphone, Wi-Fi - yours or a neighbor’s, cordless phone, active Bluetooth, etc.). When I’m scoping low-level signals on a device or proto board at home I have to contend with what’s “real” and what’s in the air. How do you avoid this airborne trash in your tutorial setups? I have a ~$300 dual-trace + storage Hantek scope and I see all kinds of annoying RFI/EMI stuff. Is it a matter of spending the bucks for something that’s much better as in quiet?

@w2aew It has one 6121 that came with it and was looking for another. Maybe I can find one NOS but will probably get a new model passive probe from Tek. The Digital Storage portion is fun to usel. I just wish I could find the option 10 GPIB or even option 12 RS-232 serial interface. Tek had an old DOS serial comm program to pull data off of it in the support section. I'll probably be wishing for a long time on those options though. I joined a Tek users group too. Thanks.

Right now I have a Leader LBO-523 scope. Not a bad scope for one that I picked up a state surplus store 20+ years ago for $35. I would love to be a scope pilot behind a Tektronix 465. Is this, or what is your favorite scope for all practical purposes? Thanks for the great video!

whats you sugestion TEKTRONIX 2440 2 channel 500 MS/s digital oscilloscope good bad? looking to buy thanks

@nlimchua I would appreciate a video to show practical applications for the following controls: Add, Invert, GPIB(gen.purpose interface bus) and the purpose of a button on my 2465A that says, "INIT@50%". thx!

I've always been curious about many of the controls that come with Tek scopes and the manuals just don't explain them as clearly as you do. Your digital SA video is good too but I'm suffering from info overload! Wish they weren't too expensive so I could have hands-on like you do. B^)

Thank you very much. I wanted to ask your opinion about two scopes. I'll ask the shorter version of the question first. TDS3054 & TDS3034 which one is good enough for a repair shop? Long version: I found a TDS3034B for a very good price. It comes with four probes manuals. But I been looking for a TDS3054B Cuz I was told by others tds3054B is the scope I should get. But I don't have the knowledge yet to know if I need the capabilities or the extra bandwidth of a TDS3054 in the future repairs. Learning how to use scopes is an ongoing project right now. At the moment I have a 100MHz scope w/ 2 probes & component tester. I am trying to get a repair lab going in the shop to complement the field service work that I do full time. The boards I will work on are out of medical and dental equipment or really any boards... CNC machine pcbs,, sterilizers, x-ray boards, chair or table controllers....motor controls, some industrial PC boards..... I can get a tds3034B for 1/2 of what the TDS3054B are going now. Which scope do you think is best for the repair work without over doing it.

Hi,just a small question: Can i use 475 200mhz crt in a tek 475A 250mhz? Or change the vertical atenuator array in the same order? Or all that in the inverted order? Thank you.

Excellent video. Great job! I have a digital Tek TDS1002B since 2008 and I'm happy with it. Recently I run into the opportunity of buying one of this used Tek 465 (not the B version) for $150. Is it worth buying and having it nowadays?
