EEVblog #187 - Tektronix TDS2024C Oscilloscope Teardown

Dave tears down the Tektronix TDS2000 series TDS2024C DSO, what's inside?
And he can't help but rant about the sample memory size and compare it to the venerable TDS210 from 1997 or so...

@vladimirFNX Unusual body colour usually means flameproof - these are designed to open without catching fire under fault conditions

I was glad to see the tear-up sequence at the end where you put everything back together. All too often do I pull something apart only to find pieces of it on my bench days, even weeks later. Thanks for the video!

@Th3Su8 Yeah, for basic use, it's OK. But that's what they have the cheaper 1000 series for. The 2000 series needs more memory to make it price/feature competitive in today's market. It doesn't cut the mustard I'm afraid.

@heroineworshipper Sony Vegas just does it. Stupid limitation of only x4 speed increase though, I usually do x10 for teardown, so had to cut out some footage.

16:08 that empty expansion header is a carryover from the 2005 model with a extension module (GPIB/RS-232 & parallel output for printing screen data)

@yanava I mentioned that the DPO/MSO 2000 is a different beast and has the memory.

@vladimirFNX I believe that the colors depend on the manufacturer and possible it may indicate an inductor vs a resistor on some units. Usually physical size will indicate wattage.

Wow! Amazing to see a 68000 in a modern device! I have actually programmed those processors, in DIP form, the size of a slice of bread! :)

Love to hear you rant as usual! Keep it up!

@Mtaalas They didn't give it to me to review, so they don't get a say in it :->
Why did they put out a 2.5K sample memory scope, the same as their circa 1997 model? I don't know, maybe they thought they could be lazy and get away with it?...

[nodariel]

Neat video. Your macro shots are looking excellent.

[ThSu]

Nice tear down. I agree with another comment. It would be nice to see a tear down of an older analog scope. On a side note. My employer provided me with a TDS2002C. Basically the same as the one you have there but with only 2 channels. It's decent enough for my work though like you mentioned, it would be nice to have more memory.

Our school uses these oscilloscopes. I like them better than other brands. Easy to use once you get used to it.

[electronicengineer]

Concerning the knobs, It would be my opinion that this scope was Designed for Manufacturing not the User, using the same knob size lowers the unit cost. This scope is a classic out-sourced component device; Screen, power-supply, etc. About the only thing original is the Textronix ASIC board which was modified from the original 1000 series. More and more device are becoming software built machine. This keeps the hardware design cost down.
Nice video. Thanks again,

@jdesbonnet I'll be getting an old Tek 2225 soon, and yes there will be a teardown.

[Afrotechmods]

Haha yeah I noticed the same thing when I was shopping for a new scope. Even my old Tek from the 80s had 4k.

[EEVblog]

@ivaneduardo747 Yep, I agree, the new intro sucks. I'm using Sony Vegas to edit now, and it doesn't have the same cartoon effect. I'll have to still use VideoStudio to just do the cartoon intro effect. More effort, but probably worth it.

[EEVblog]

@ivaneduardo747 Yes, it would be a completely custom designed for Tek.

[mikeselectricstuff]

@Bushougoma Because anyone who owns a scope ought to be able to resolder a new one.Sockets can be unreliable.

[EEVblog]

@abraxalito Could be! Not a fast beast by any stretch... I'm sure the old TDS210 was MUCH faster?

[EEVblog]

@tearabite It was hardly a review, just a few comments on the basic layout.
