I've heard about these new-fangled Oscilloscope things for a while, so I finally bought one... from 1946! This is about the smallest, simplest, and cheapest scope I've ever seen, so I figured it'd be a good starter for someone like me who has never touched one before!
This is a Philco Junior Scope. It uses vacuum tubes, has a tiny CRT display, and only has 7 controls. I was able to do a couple interesting things with it, like evaluate power bank inverters and look at audio waveforms.
I'm looking for recommendations for a next step in my oscilloscope journey! What should I look for? What features are vital and which are unnecessary? What can I do with one that would help me with the type of projects I do? Suggestions are welcome!

In my lab we use an oscilloscope to do gamma ray spectroscopy with scintillators. Basically the peak voltage reached by the photomultipler is proportional to the energy of the gamma ray and I scan each waveform output by the trigger for the peak and also integrate over the signal. A good oscilloscope and handwritten software can replace an entire data acquisition crate if one is good enough. And the robustness of the data by having a full waveform allowed me to remove noise signals since they have a different shape and timing. Oscilloscopes are awesome!

If you decide you want to try a more advanced scope but still a bit retro - I have two Tektronics scopes from the 70s or 80s. Still analog. Now-defunct local company NCS/Scantron engineers used them to diagnose their scanner products. If you want more info let me know. I never got around to learning and I would be happy to pass one or both on for free to someone who will use them.

My first oscilloscope was a (1947!) TekTronix 512. I had never seen anything so beautiful. I was 13, and my dad brought it home from the electronics department of the museum where he worked. This was around 1976, so that scope should itself have been in a museum! But it was useful to me for many years after that. Weighed about 30kg as I recall. I used it for debugging my first 8080 computer build, and a number of other projects. Anywhere were you have electronic signals other than DC, an oscilloscope can help you check them to make sure they're doing what you expect. Modern scopes are often multi-channel, have "cursors" for measuring voltage and frequency, have various trigger modes, etc. No electronics lab in the last 70 years has existed without a 'scope or three on-hand.

One of the main uses for an oscilloscope is to take measurements in the analog domain. Even digital oscilloscopes tend to be showing you what's going on with analog signals. But there's a couple of things you need to take measurements. 1) the scope needs to be calibrated, and 2) you need a graticule, which is an overlay of grid lines over the display. With these features, you can set the horizontal sweep to some calibrated value, say 5ms/div. In such a case, the grid lines are 5ms each and you can, for example, see what time elapses between interest points in the input waveform, such as the peaks of sinewaves. Also, vertical grid lines and vertical calibration allows you to measure signal amplitudes, as the vertical amplifier should have volts/div settings, so you can set it to .1 v/div and count grid lines between the bottom and top of a waveform in order to see what the signal's amplitude is. Trigger circutry was developed by Tektronix in I think the 1950s, so earlier scopes aren't going to have trigger circuits, though they may have synchronization circuts that accomplish a similar function but more crudely. Trigger circuits allow you to cause the horizontal sweep to wait until the input signal gets to a certain value, and makes it easier to see less frequent signals, or pick trigger points on more complex signals in order to stabilize the display.

I studied electronics in the 1980's and they said the same thing about digital multimeters. A multimeter or scope is a tool. I want to see the voltage or the waveform of what I am testing or troubleshooting, the sooner/easier the better. Nothing was lost in a digital multimeter that could automatically set the scale and show you the voltage vs. having to manually select a scale and then look at an analog meter and try and decipher what scale to look at and what voltage you were measuring.

@@RingingResonance I agree with at least two Chanels. I don't see a sharp cutoff at 50 MHz, it depends on application. 100 kHz is good for simple audio and mechatronics systems. 10 MHz is good for most slow digital serial communication slow Can busses, some IF circuits in radios, most switchmode power supplies and motor drives. 50 MHz is better, can be used in more systems and gives better confidence in that the measurement captures all relevant transients. Faster digital circuits or rf circuits require higher bandwidth sometimes in the GHz. For general use I consider 10 MHz to be minimum, 100 MHz good, higher bandwidth if you have special needs and the budget. There are some cheap 8 Channel 100kHz USB scopes that seem useful but then it is maybe more a data logging system than an oscilloscope.

You can find portable analog, solid state scopes with more advanced features like triggering modes and muliple channels made by companies like Tektronix. Make sure the seller confirmes that if it runs on a battery pack it hasn't leaked since the 80s. I recommend sticking with analog for beginners as digital scopes only really teach you about menus (also if you overload and break it with the signal it's at least possible to repair unlike most digital scopes).

Think of an oscilloscope as the next step up from a voltmeter, or a voltmeter that graphs over time. You can even use one as a voltmeter, but I've only done that in a pinch when I misplaced my meter. I couldn't recommend getting an old scope these days, given what you can get in a cheap modern scope. Your projects keep intersecting with territory where a scope can paint a picture rather than giving you a number and a picture can be worth more than 1000 words when describing what a circuit is doing. The important part here is that you apparently understand a scope is in your future. Lol. I recently picked up a portable 170 MHz bandwidth unit from Owon which is more useful than any scope I had in the 80s, but the cheap desktop units today can't be beat.

I have a cheapo 2 channel usb scope and it has helped me a lot. So many things happen faster than a voltmeter can react, and without a scope it will be invisble to you. When something isn't working I put the scope on it and I often see things I didn't even expect - bad regulation, ringing, noise from another part of the circuit... It's great. But since it needs a computer it isn't very portable.

yeah, thats where they shine. a voltmeter gives you an idea, but really does not tell you what's happening. if you have found a USB scope useful, I would recommend getting your hands on an actual bit of hardware. my rule of thumb, buy a cheap one first, if that is useful or you break it from use, then you can justify spending some money. call me oldschool, but I like my knobs n dials. SDR and a USB scope (which is sister technology), is great if you know exactly what your looking for. but having a bank of knobs you can navigate without looking at whilst keeping your eye on the screen and hunting is fantastic. someone in the flight sim community aught to get in bed with an SDR guy. A bank of dials, once you get used to them, is am incredibly snappy user interface.

NAWWWW, that thing is SO CUTE! Like most complex things, there is alot of knobs and switches that you generally dont use. unless you reallly need to. I wouldnt think a 1940's unit would be the best thing to learn on however. in the age of digital, LCD 'CROs', the big old analogue ones can be had pretty cheap. and I think they look way cooler. Its bulk never bothered me, as I prefer my monitor higher up, so I just replaced the stack of yellow pages with the CRO... Some things I find a scope most useful for: if you have a dodgy PSU, It can read just fine on a multimeter (and the feedback circuit). but if you have bad regulation or a fussy SMPS, it can make noise on your power which can cause all sort of havoc. weird glitchy results, strange intermittent faults, that sort of thing. your multimeter might show a perfect 5v, but the PSU is actually trash (probably a bad cap or diode). If your dealing with Serial data, a 'Digital Storage Oscilloscope, DSO' can be really handy, it will capture and store the waveform, so you can 'scrub' through it like a video editor, and often compare multiple channels. invaluable if your questioning 'is my widget actually putting out valid data?' can quickly show you if your signal may be inverted, a lower/higher voltage than expected, not a clean waveform, that sort of thing. the really clever ones can actually interpret ASCII or other encoding. Very useful if your trying to get thing A to talk to Thing B. Obviously measuring frequencies. of course there are digital widgets that can do that, but that meat potato between your ears can do alot of post processing and work out exactly what you want to look for. ie, you can pretty easily see multiple frequencies at once, and just measure the one that you want. If your trying to get filters to work, invaluable. or any other resonant circuit for that matter. And the obvious application, they look COOL. When I was an electronic tech, when I first started I clawed out an old tektronics Scope from under the stairs and over the years it became part of my battlestation. It took about 30min to warm up enough to give accurate readings, and some of the knobs were alligator clips. Id wired the whole desk into one main switch, so PSU, Iron, Scope, PC monitor, audio amp, was on one RCD protected circuit (so I could pop breakers without knocking over the whole business... mostly... they didnt like that). Get in, hit the lights and workstation, make a coffee, have some banter, figure the days plan, and by then it was cooking. but I didnt want to turn the CRO off, cos it always gave weird results when cold. so I just hooked it up to the HiFi system and let it dance along to the music. Milkdrop is cool and all, but a CRO just Groovin' in the corner of the room. thats just cool (even if there was a very practical reason)

Great choice for a first scope given the vintage factor, but it appears to need a re-cap and recalibration. The response looks pretty out of linear. That shows you the most basic of basic and when you want more, there are so many good, cheap scopes these days. Anything from Owon, or Rigol, or Siglent will do you great when you want a more advanced unit.

I recently got an Agilent 54622D, it's a lovely digital scope with a green phosphor CRT. I don't have much experience with more recent scopes, but this one has really responsive input, the knobs feel like analog controls! They even have acceleration for doing large adjustments with a quick flick of the dial, and then more precise control when going slower. For me, the 16-bit logic analyzer has already helped me revive one ancient computer (an Apple IIe), so I find that quite useful as well.

Think of it as "ground" rather than the negative lead on a multimeter, so you'd connect it to mains earth and the positive to hot. It's also a safety precaution to prevent ground loops, because on most scopes the ground lead is directly tied to mains earth.

While this is a very interesting oscilloscope from a historic perspective that is still useful in some cases it is very limited compared to a newer model. The ability of a digital oscilloscope to capture events that don't repeat frequently is very useful in many cases, especially in projects that includes e.g. mechanical components. Given that you work on different projects at different locations I think a basic handheld oscilloscope with built in multimeter and signal generator would be good. I have an OWON HDS2102S that i find useful. The slightly slower OWON HDS272S cost about 150 usd and I think you would find it useful. It has some limitations but it works for many cases. Given that it is the size of a multimeter and contains a multimeter makes it likely that you have it with you when you need it. You get a better oscilloscope for the same cost if you go with a USB oscilloscope but then you need to bring a laptop and it is not as convenient. There is also cheaper handhold versions but they are often not as good.
@larslindgren3846
@larslindgren3846 Месяц назад
I think the main limitations of my Hds2102s is: Small screen and that settings are done through a menu system. But that is a direct consequence of the small form factor. Short memory, only 8000 points. Limits the ability to zoom in on the measurement after the event. Limiting if you want to look for glitches e.g. bad contact during a longer measurement. Much better than analog scopes but for a few hundred usd more or in some cheap USB oscilloscopes(using the Laptop memory) you get millions of measurement points in memory. 8000 points are enough for most use cases. The lack of serial decoding. You can check the signal quality of a serial comunication signal but not easily read the data. The lack of FFT, many other digital oscilloscopes can show the frequency content of a signal like a sdr can, is sometimes useful. Then lack of frequency sweep in the signal generator and the cumbersome menu system makes it slow to e.g. Measure the frequency response of a circuit at many different frequencies. In many cases it is enough to measure the step response instead. A few times it has given extremely noisy measurements but restarting the instrument have solved the problem. Probably something in the digital data processing that get stuck in a faulty state. Electric safety is probably significantly better than the cheapest scopes or the one you have but not as good as a high-end Fluke or similar. Unable to record/plot the multimeter measurements. Some handheld "oscilloscopes" uses the multimeter inputs instead of separate oscilloscope inputs. This make it possible to record current or resistance variations directly. These inputs are however much slower. It would however have been very easy for the manufacturer to add the ability to log the multimeter readings in addition to the oscilloscope functionality. I think this is reasonable limitations at this price point.

Cute little scope. I really like it. But without proper triggering it has very limited use. Also, it distorts too much to be useful for any kind of measurement. TBH, your typical, entry level, digital, desktop scope is about the same size and usually has 2 channels, 100-200 MHz bandwidth, all the crazy triggers and such, memory, FFT, protocol decoder, larger display and still costs very little (about 200 usd for a Hantek, OWON or something like that). Though, I still prefer to use analog one for certain applications, which include radio stuff. But proper analog scopes tend to be rather large and heavy.

If only we were all so realistic about stuff we all buy … 😂😂 That’s also a good way to limit clutter to some extent and spending . “Might get used once or twice as a novelty and then thrown in the back of the closet somewhere “ Thanks for the video and also keep saving things for parts .

Most pre 70s only go up to about 1 or 3 mhz. I got an mid 90s HP 54610a that goes to 500mhz there about $250 on eBay. Mostly I use the HP to check other gears frequency. And the old one's are nice because there very hard to damage.

I had a very similar scope years ago in the 70's its great for making a Lissajous pattern I would take and hook up the X axis to the left stereo channel and hook up the Y input to the Right channel and watch the different patterns. have fun enjoy

Very nice. I recommend a scope with a trigger function. It is useful for hardware hacking in case you ever get into that so would be a good future proof. Having at least 2 channels is also helpful in case you for example want to see how a clock signal relates to another signal synced by it.

I highly recommend getting one of those Tektronix analog oscilloscopes, a Tektronix 545 for example. They work great, have a ton of value for the price and most importantly you will learn a LOT about how to use scopes with one of those. It would definitley suit you better than one of those cheap chinese mikrocontroller kit scopes, they're just a pain to work with, very limited in capabilities and you learn next to nothing using them.

Time domain reflectometry (measuring length of cables, checking for breaks or shorts) is my favourite oscilloscope use. Can be done with only a few components too. Might not work so good with your basic unit though! More info here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-z6UJPqQYzNc.htmlsi=Mr05jpKfy5hrZTut 8:00 - Maybe your mains actually does looks that ;-) I put my modern unit across the mains some time ago and that didn’t go well at all.

You need very long cables to do time domain reflectronomy on a 100 kHz scope like this. Minimum about 500 meters to resolve any reflections at all.

repairs. you can use it to check signal lines on your "i bought this but there is no manual" devices. and power. that particular system might not give you entirely accurate diagnostic values but typically the display is used for demonstrative diagnostics like "Yes, it IS wiggling up and down" or "No, it is tied to ground/pulled high" or as you have shown here "the shape of this signal is n over time" as opposed to more mathematical applications. Is a devices CPU actually starting up or is the device halted. Scope can tell you. Does the signal make it to the external plug or is the chip dead? Job for a scope. Are the logic levels roughly in a non insane ballpark or is something really obviously woefully wrong ( voltages just being held at some middling level, or lacking sufficient volatic deflection to register an edge )... Scope would be nice. And a bunch more. Mainy related around "I have NO CLUE what this device here even does / expects / transmits / insert any doing word here " It's like a logic probe, a multimeter, frequency counter, visual data analog, Lissajous figure generator. and assuming you have two channels phase meter, A spectrum analyzer, even just a "Time Interval Analyser" where you need to observes timing differences between signals. fancy ones are great for logging and complex channel maths blah blah - but a lot of the time just a quick and dirty visual way to see "ARE WE THERE YET?" is what 40 bucks got you

volatic = voltaic. my bad :) and strictly speaking voltaic means batteries were involved. but whatever. you get the drift. "Electric go brrrrr"

Gabe, That is a basic oscilloscope that you have. But, if you get a decent dual scan digital 100 Mhz scope from eBay, you will grow to love the thing. You can do a lot with a good scope. You can measure frequency, voltage, and a number of math functions for wave analysis.

Think of it as a voltmeter, with a very accurate clock. It just measures voltage over time. Edit: I have a 1980s Panasonic two channel analogue oscilloscope which is all yours if you pay for the postage. Unfortunately for you, I'm in the UK, and it would be cheaper for you to buy a brand new digital scope. It weighs a ton.

Adrians digital bacement does a few reviews of really cheep scopes that will be way more featured and useful for what you would want a scope for. Using i don't know exactly what you would use a scope for, as most of your radio projects can be captured with a sdr. But when you need it it's extremely useful. You can use a scope with fft to align antennas. I beleve it would be more useful if you where transmitting.
@larslindgren3846
@larslindgren3846 Месяц назад
I think most of the radio signals he receives are too high frequency for a budget oscilloscope. I think it would be useful for checking that DC supplies voltages are clean enough and troubleshooting circuits that control e.g. the motors that he uses to point the antenna dishes.
