Don, There is a Lemo USA Inc., somewhere in Santa Rosa, Ca. I do not think there is any manufacturing there, that must be a Swiss variation on the theme of Tekintag (Tektronix International AG). They

Now that you mention it (and I thought about it earlier but I don;t remember enough to hold an intelligent conversation) we were given the analogy that the screen was like a multitude of small

There was actually a storage tube prior to 1961. The first F-4 Phantom II was flown in 1958 and the radar scope was a DVST (Delayed Vision Storage Tube). The image would pretty much stay on the screen

Sorry for the confusion Lynn. I was referring to your description of the mechanical polarizer lens used to dim the display. Rotating one of the lens to control the light attenuation is analogous to

I checked with my copy of Pete Keller's book, "The Cathode-Ray Tube Technology, History and Applications". He says write-through capability was added to the T4014 in 1978. And, "Color write-through

Lynn, What you describe is also how liquid crystal displays work, except the LCD material is what rotates the light. The latter is controlled by an applied voltage, with the LCD material sandwiched

Just to add from Pete Keller's book, "The Cathode-Ray Tube Technology, History and Applications", he refers to the "Anderson bi-stable, direct-view, storage tube developed by Robert Anderson of

Hi Dean, I think the two color DVST came later (post 1976-77). When I first saw the 4081, it was green on green, as were the Battlestar Galactica shots (sorry, don't have either the pilot movie or the

I believe the manufacturer of the 4 pin plug Dean refers to is LEMO in Switzerland. Beautifully machined metal parts (reminds me of a fine watch) and gold contact pins. Pulling on the outer shell

I think there were two versions, with the 4052/4 version accounting for the increased speed and taking advantage of non-store which IIRC did not exist on the 4051. Definitely no orange write-thru. I

Just off the subject of the compatability of 5000 vs. TM500 plug-ins, I can't remember if I mentioned my modification of a 5CT1N curve tracer to work in a TM500 power module. After careful research

The TM500 and 5000 plug-ins are compatible only in their mechanical housing. The card keys will prevent you from swapping the plug-ins. 5000 plugins are fully dependent upon the mainframe for their

Don, I remember the little thrusters and dust kick-up. I thought it was the 4054 that had the write-thru and didn't remember about the 4081 (glad to finally get that model number!). The write-thru was

The main reason tek made the low bandwidth 5100 series (also identifed as D10/D11/D12, etc.) was to service the biomedical/research community, that needed high sensitivity and low speed, and often had

I am also a newcomer to the community. I bought my first TEK in september. I needed a differential amplifier for triboelectric cable noise measurements and an oscilloscope for it. Budget was tight and

Hi Lynn, Comments below: Lynn Lewis wrote: I don't even have a good guess on this one. I'm with you. I think the best buy seems to be TM506's if the prices you quoted are accurate. No I guess I don't

I wish I could help with the power supply problem. I bought a 7704 that works great and a 7704A (from Ron Kovac) that has some problems. I know the HV circuit works, however, because the readouts show

My guess is that the 503's and 504's are more portable. I have two 503's and one 5006 (506 on steroids!!). I don't think the 5xx plug-ins fit the 5000 series, but I may be wrong. I understand that the

I never owned anything made by Tektronix in my life until December. Now I have 6 scopes and a bushel of plugins. I have two questions, the answers to which are probably obvious to you guys but not to

I have one of those, too, and would like to be able to use it with some of today's pc's running Linux, or even Win98. Anybody know of a program that will handle that? I used to write real neat letters
