Basic Oscilloscope 101

[1fornone]

Thanks for posting this. I just got a 'scope and have been teaching myself how to use it

[AllAmericanFiveRadio]

Thanks 1fornone

I have analog and digital volt-ohm meters, capacitor meters, current meters, watt and SWR meters, and more. But if I was limited for some reason, that I could only have one item of test equipment. it would be an oscilloscope.

A very useful tool when properly aligning a tape deck or location distortion in an audio circuit.

[BadChizzle]

That... Was fun!

I'm hoping to get an O scope this year.

Thanks for the awesome video!!

[AllAmericanFiveRadio]

Thanks BadChizzle

Good, you will find it very useful.

Where are you feeding the signal into the oscilloscope? I don't see anything hooked up to it.

[AllAmericanFiveRadio]

Upper left corner is the input.

Almost as good of a deal here. TEK 2230 DSO on the factory matching rolling cart with front cover and manuals for 78 dollars. It was at an industrial liquidator. I went in there initially to get a deal on an office chair. The Tek was off to the side with some projector equipment. Who uses projectors anymore? I asked about it and the salesman said the EKG is $100 but it doesn't work. I rolled it over to a power outlet and plugged it in. Read the manual and got it to POST, it showed all good.

Rick,

As usual, great job, my friend. I really like that o'scope. I was leaning toward a Leader scope when the Tek 465 fell into my lap for $60.00. It was a deal I couldn't refuse.

Terrific job on the demo. Will there be a "Basic Oscilloscope 201"...like how to utilize the time base to determine frequency? This piker could stand a quick refresher.

Regards,

John

Thanks joernone

Hey John,

That's a very nice oscilloscope too. I just happened upon this one.

Regards,

Rick

@joernone Tektronix 465? Thanks, Sorin

[joernone]

@SorinG2010,

Yes.

I wish I could find an 'scope, a good one but cheap, maybe second hand. It would help a lot with my amplifier projects.

[AllAmericanFiveRadio]

Thanks CoolDudeClem

I got this one from a flea market.

[BadEditPro]

Fantastic video... Watching the IF really gives an excellent visual representation of what's going on with AM. :) JC

[TubeShortwaveRadio]

Thanks BadEditPro

Thanks JC,

Usually when I'm troubleshooting I do not change the Time Base very much because I have been using an oscilloscope for many years. So for this video I wanted to make clear these functions and what they mean, for people who have not used an oscilloscope much or not at all.

Hi Rick. Thanks for another GREAT video!

[AllAmericanFiveRadio]

Thanks wolfhawg

Very well put together video, succinct and methodical. Thank you.

Have you a preference for analogue scopes over digital, and if so for what reason?

[AllAmericanFiveRadio]

Thanks APublicDomain

[K0W0O0N0]

Your explanations are great!

Thank you for that...

Cheers....

Thanks for this, excellent,very understandable, and i take this

chance to thank you for all the other wonderful video,

we have learnt a lot from you, thankyou very much.

The first time I used an oscilloscope in college, I thought I would break it by turning the knobs the wrong way. After becoming confident enough to use it, I pressed the power button to switch it off and it slid backwards off the shelf and crashed to the floor! It never worked again, the poor thing.

[AllAmericanFiveRadio]

Thanks jimbobg65

Gravity!

[FelixTheHouseFreak]

Excellent just excellent, thank you!

Rick, you did an excellent job with this video. Were you inspired to make it after I made mine about raster scanning? :)

I have a few questions about the scope. How are two traces shown on the screen at once? How does the sawtooth oscillator for the time base have such good linearity and frequency range? Does this scope have a z-axis input and is it invertible? This would be a good scope for a TV converter circuit like I made because of the screen shape.

Very easy to follow and understand.

[AllAmericanFiveRadio]

Thanks CameramanLink

That and several requests to do more basic stuff. It does not have a z-axis but it does have a high quality oscillator for the horizontal.
