Which oscilloscopes have orange CRT monitors?

I have searched everywhere, but I cannot find that information. The LeCroy 9350A looks great, but I can't afford one.

I will always like the vintage Tektronix cool blue CRT's.

Who here has vintage oscilloscopes?

I'll bet my father still has one. He's a long retired electronic engineer. I remember and old CRT model sitting in his basement, along with an old tube tester and the largest collection ov vacuum tubes this side of Radio shack.

Went to school for electronics in 1960, worked in a TV repair shop about 12 years and only remember using one once. The guy I worked with showed me the shortcuts for servicing electronic equipment,and a lot of Oscilloscopes in repair shops were used about as much. Engenering would probably be a different story.

I have 2 vintage Tektronix oscilloscopes--one works and the other doesn't.

when I worked for Digital Equipment Canada as a tech many many moon ago, I was issued a Tek scope - I think it was a 475 - certainly analog back then and a dual trace if I remember

no longer have one but recently purchased and am using a Siglent SDS1104XE which is actually quite a nice little scope

I have an old US Navy one I bought used (green CRT, not orange) and a modern digital one.

Here's one like the one I have:



I use the Digital when I have a real need, the vintage model is just fun eye candy with/for my music gear.

There's a couple floating around my job. Blue Tektronix.

My HP 1222A, blue display.

Correct about the LeCroy digital scopes. These used a raster scan CRT, like an old computer terminal or display. Other CRT display that had a naturally orange-ish color were some of the radar displays, due to the very long persistence.
The color is dictated by the phosphor screen characteristics. The phosphor needs to have the correct decay time and intensity for the application. The classic Tektronix, or similar scope with the blue filter, actually have a green-blue light from the phosphor. Back in the day of photographic recording of scope traces,there was a blue phosphor that more closely matched the film sensitivity. These were somewhat difficult when viewed with the eye. Some special applications also have a whitish display.

Thank you all for the information.

I just bought a LeCroy LA302 100MHz 3-channel scope for home hobby use. Eventually I'll find a deal on a nice blue Tektronix and a newer digital scope.

I have three scopes. Two have CRT screens. The one I use is a Tek scope has a color LCD.

This followed me home. Been awhile since I've used a scope but chased many 1's and 0's around back in the 70's and 80's.

Had to travel with a Tektronix 465 under my seat all over the US. What a pain in the ass.

JAMES MILLEN Manufacturing Co., Inc. (USA)
Model:90915, made in 1956 had an orange screen

I was auditing stall yesterday and ran across this one being used. Last calibrated in 2000.



I personally use a PicoScope, USB O-scope. It's great for traveling overseas. I can pack my o-scope in my backpack.

Many years ago, at the second auto repair shop I worked in, the shop owner had an old Heathkit oscilloscope in the back room that his father had built from the kit.
It had a green CRT and I became fascinated with it.

I wound up using it a bit for testing primary ignition patterns. (This was back in the 80s and we were still working a lot with vehicles with old school ignition points.)

Fast forward 15 years and I had access to a Tek portable digital scope. I think it had a 3.5 inch screen.

I also wound up with some cheap 20 Mhz analog scope and a pair of Fluke scope meters. A 97 and 98.

The Fluke 97 was the most capable but the 98 was geared towards automotive.
