I have my Hameg dual trace 30 MHz scope, this one will replace it, i think.... but as i said, mostly a 20 - 30 MHz dual trace is what we use most.
This Hitachi is of a totally different plane, overkill for what i mostly use the scope for.
I'll first have a twirl with is and see how i like it ;)

Hello.
I use an old Motorola service monitor that had a Telefunken CRT scope in it and was converted to LCD, giving me the example I needed to understand how this works.
Now there are a lot of projects out that allow you to build your own with everything from a TV to a computer.
Old scopes are plentiful and cheap if you look.
And, the conversion of the R-2200D service monitor is so totally cool!.
The original CRT was the entire section of the thing, front to rear.
The replacement LCD is but the very front section and is supplied with its own battery.
Battery for the service monitor itself was going bad and so I was provided with a pigtail and bracket to mount a common lead acid pack inside the battery box, much cheaper and the battery life is now unreal, 10 hours is not a problem.
I got the service monitor much the same way, from helping move stuff around.
Nice catch, Cor. We are all jealous.

All the world’s a stage, but obviously the play is unrehearsed and everybody is ad-libbing his lines. Maybe that’s why it’s hard to tell if we’re living in a tragedy or a farce.
Hello.
Go to the batlounge, there you will find not only pix, but an explanation of how the conversion works.
The R-2200 service monitor is a nice service monitor but the CRT is NLA, and everything is done with the screen.
If you follow the directions to the letter you will have a good conversion, any changes and you are on your own.
The board that is referred to is a copy of a board intended for just this application, replacing a CRT with an LCD in a scope.
I do not know much more than what is in the documents provided.
There are dozens of plans on converting a TV to an oscilloscope and plenty more on doing this with an LCD display.
Note that there is a very good reason that the R-2200 scope supply is isolated from the unit B+ proper, do not try to change this portion of the original wiring, the unit needs this isolation!
Give me a link. I've seen lots of stuff for converting computer monitors and TVs to LCD screens but I've yet to find any info on anyone who's successfully converted an oscilloscope.

Hello.
What I have was installed by a shop down in Juarez Mexico a few years ago and is sold as a kit to convert a CRT display scope to LCD, a complete package.
But there are now dozens of the same out.

Some on the batlabs were asking me about this and I have no answers, both in that I did not do the conversion, and that it was a kit that simply is installed.
There is one phillips video IC on the board and a few transistors but little more.
Again, this product is a commercial package, follow the directions and it works, except I was not the one following the directions.
As usual, the link doesn't prove your point. Don't you ever get tired of that game, Hajji Rudi?

Hello.
What kind of point is there to prove?
The LCD display is treated as any video display on this thing.
And, as I have written, I do not know how it works, it was a kit that was not installed by me.
Unplug the standard computer video connector from the board and plug in a computer monitor, CRT or LCD, and as long as the sync is good it works.
Unplug the computer monitor and plug the display back in and it is back to square one.
Again, this is a kit, one of several that are very much available on the market today.
The LCD display is something that happens to fit and is of the ratings needed that was surplus.
The prior LCD display was a bit smaller so I replaced it with one that fills the entire area.
That is the full extent of what I know about it.

I made a quick piccie.
Don't mind the rest of the trash, i know i need to clean up my working room....
There was also a Konig meter and lots more DVM's etc, but not enough place to put it up for the picture.
