Can you set the input impedance on the x-e model?

Ironically it looks like another piece of software called Logic Pro.

If you have an 1104x-E, you can hack it to achieve 200mhz. It has the exact same hardware as the 1204x-E. The only drawback is the lack of ability to update the firmware. When they figure out fast/live web control, I'll undo the hack because I only needed it to check a 315mhz remote signal. It can read above 300mhz fairly well for a stock 100mhz scope. Regular firmware updates will keep hardware hackers at bay. I hack my own stuff just for kicks.

Awesome video! Thanks so much! I just bought one of these models used and your video was key to my decision. 73

What is the MAX II chip??????

At that point, in that day, it was easier just to write the machine code on paper….

wrong too many times to count. Slow down, write down you script, edit it, and pass it by someone who knows engineering. This was too embarrassing to watch

Excellent Video, Thank You. I had just ordered one prior to watching. This will definately Suit my Purposes ⚡🙏⚡

memory from cheerios? i don't remember! but it's in the wash! good luck pal !

Bought one just before the pandemic. Used it a couple times, shut it off and let it rest on my desk shelf ever since. Went to use it 2 months ago and it won't do anything! Seems that it is locked in the "ARMED" mode and won't let any control buttons work. Any suggestions?

Brilliant!

I recently built a 4 X 4, 16 bit plane of magnetic core memory as a demonstration and works very well. I have 1500 cores so I might make a stack of either 4 or 8 bit words and go from there.

VHDL/FPGA dev here, would be cool to use this for microcontrollers! Thanks!

your videos are fantastic

yes it is

i like it

the small 10-pin

tanks a lot

well done

Great video sir! Would this be a good product to test speakers like tweeters, mids and woofers? I have about a thousand I need to check for sound. If so, how loud would the test be? Thank you.

I was a maintenance man on the NORAD SAGE Computer system (IBM ANFS/Q7). The largest (physical) computer ever built. When they finally shut down the SAGE systems in the 1980s I managed to snag a piece of the ferrite core memory, which I have displayed in my hime office to this day. As an aside, Hollywood bought some of the components of the old SAGE systems for use in TV and movies. I've seen the maintenance consols in shows like the Six Million Dollar Man, Battle Star Galactica and even one episode of Columbo. In the movie Austin Powers, there is a console that housed the long range radar input channels that can bee seen in the background in Dr Evil's hideout.

too far,,, zoom in,,, even on 65 inch tv

Metric??!!

The point that most folk miss is that you rarely actually NEED to know a voltage accurately. If you are making or repairing an amplifier or some digital circuit and you adjust the power supply until your meter says 5.00000 volts, but due to meter error, in fact it's 5.05 volts, does it really matter? Very rarely, particularly if you use the SAME METER to measure other voltages in the circuit. And that's a 10% error! Most DMMs, even the cheap ones, will be far more accurate than 10%. Engineers spend a lot of time COMPARING voltages. Is the voltage at point X higher than that at point Y, when it should be lower? If you compare two voltages that are supposed to be the same and one of them is a little high, you're probably going to say "Well, I guess that's near enough". But if one is half the value of the other, then the response is "Looks like we've got a problem here". What is important is REASONABLE consistency, repeatability and linearity. If you measure two voltages, one of which is half the other, then it's often important that the meter gives two readings that are in the correct ratio, i.e. 2-1 within a reasonable deviation. We happily work with 1% resistors or worse, we measure voltages on analog oscilloscopes by counting graticule markings (10% if you're lucky) etc. and our circuits usually work just fine. Clearly, there are times when absolute accuracy is vital, but most engineers rarely if ever work on such projects. The rest of the time, owning a meter with umpteen figure accuracy is just a matter of pride - like owning a new car - a nice to have, but not essential to get the job done. And of course, just because a meter has 5 digits, doesn't mean it's accurate - precision and accuracy are different things.

As hobbist, does it really matter if the 3rd or 4th numbers after point not accurate?

Shaving with a dollar store razor vs lawn mover when you can...🤣

Oddly enough you made me remember that I have actually encountered the same problem with a poorly laid out PCB and fast logic IC transitions you described. It must be quite a common one by the looks of it. But we did not redesign anything, instead we ended up using a somewhat dirty trick to overcome the issue. When I undrstood what was going on the board I decided to just cut the traces right near the output pins of the ICs and inserted 470 ohm 0402 resistors in order to just confirm that it would fix the issue. And of course combined the capacity of the traces it was well enough to slow the signal down and pretty much eliminate any of the "ringing". The proper way would be to correctly redesign the board with modern components and technology in mind but it was a very old and obsolete soviet era digital device with very limited use so we wanted to get over it with as little time and effort as possible so we just documented my "solution", added the pads for the resistors and called it a day. If you have an excessivly high performance logic output then it is not a problem to slow it down. Going the other way though is nowhere near that easy.

Amazing!

Any new giveaways? Trying to score an oscilloscope and times are trying here in NY >.< hope all is well!

Where is a rise time improver? How can I make it?

goood

Great advice

Really Informative

Great advice

feels good

After looking over specs of some models, and partially based on this review, I bought one of these and just received it. I have about a half century of electronics experience and appreciate how easy this is to use in spite of the vast number of capabilities it has. (Far more than the number of physical controls would suggest.) On anything like this, there is a tradeoff between the number of controls to slather onto a front panel and the number of menu driven choices with soft keys and/or arrows and such. I think this has a very good balance. I have used a great many models of test equipment over the years and believe that you shouldn't have to make a career out of trying to learn how to use this or that generator or scope or whatever. That with basic knowledge of what you want out of something, it should be easy to, without ever looking at a manual, quickly do what you need to do. This has the "easy to use" I prefer.

Good idea on the "rise time improver". It reminds me of something VERY funny in one of the National Semiconductor data books probably back in the 1970's. I forget the IC numbers, but one was titled "Fast Buffer" with a specification of a 1,000 Volt/uS slew rate. The next page had the title, "Damn Fast Buffer" with a 6,000 Volt/Us slew rate. Back then, you sure didn't expect to see that word in a data book.

For you true experimental nerds out there, here is a very cheap way we made an "arbitrary waveform generator" in a college class. We took a regular analog CRT style oscilloscope and made a cone shaped black hood over the screen with a photocell at the other end of the cone. So, the photocell "saw" the light of the dot going across the screen. The output of an amplifier controlled by the photocell is then fed to the Y axis of the scope. We could cut a paper mask in any shape we wanted and affix it to the front of the Oscilloscope screen. We adjusted the gain of the amplifier so that about a half of the oscilloscope dot showed. If more than half a dot showed, the amplifier output would lower. If less than half a dot showed the amplifier output would increase. So, this was a closed loop control system that would try to maintain a half dot showing. Whatever free running sweep frequency we used produced an output with the waveform shape we had cut out of a piece of paper.

This was excellent! Where can I find a bit more details about that awesome DIY probe?

Uhmm.. subscribed.

Fantastic tool. Doesnt replace a scope but should be rhought of as just as critical

Llegue tarde para el sorteo :S

thats cool

Me 23 years old and I prefer 1950's scopes 🤣🤣🤣

the only question i have is what is the load.... seems to me that could be a mismatch in the line... but... well...is cheap. for sure need a filter

Conferences like this are money grabbing bs. "Registration Fee All Access Pass $290" !!!

Looking forward to hearing from you and the other participants 👍😀

i would like to know who these people in the video are :)
