Tektronix is Grrreeaatttt!!!
Isn't free speech a wonderful thing? I followed the Tek thread with
interest and am wondering if the whiners actually: 1. Have a use for instruments of this caliber 2. Know how to use them properly I have used Tektronix instruments for almost 30 years now, and don't know how I could have got along without them. Most of my work has been in commercial radio and television. The manuals are written incredibly well, and I have received assistance from tech support on devices more than 25 years old. Try that with Hitachi, Leader or Phillips or Sony. And I could still get parts for them! I reflect with fondness on repairing a device like a waveform monitor, more than 20 years old, and finding a small coil of silver solder on the chassis in a place that was designed for it, tucked neatly in its own "home." Tek has used silver solder for decades now...they have always known it makes a better solder joint...and they want their stuff to keep on working, 24/7 for years and years. So they put their money where their mouth is, and provide the end user with what they consider to be a lifetime supply (for that instrument) of the stuff. And now I hear that they desroy their own equipment so they can sell more new stuff?! Baloney. I think I am hearing from people who not only do not understand that "you get what you pay for," but have no use for the quality and accuracy of the products they are complaining about. Merry Chirstmas and Happy Holidays to all. de WA2AFD |

@juno.com says... And now I hear that they desroy their own equipment so they can sell more new stuff?! Baloney. You're wearing rose-colored glasses. They absolutely do destroy older equipment via the trade-in "bounties" collected by resellers such as Tucker. This is no secret in the industry. That doesn't make them evil, and it doesn't make them "suck", but it does (IMHO) demonstrate a lack of respect for the engineering ethos and tradition that made the company great, while taking perfectly good equipment out of the ham/hobbyist community forever. You could divide the T&M equipment world into two categories: stuff like logic analyzers and signature analyzers that's pretty much doomed to obsolescence the minute the first pilot build rolls off the production line; and gear like oscilloscopes and spectrum analyzers that still serves its original purpose decades after it's out of production. HP, for instance, made a lot of great test equipment, but a lot of it fell into the first category and nobody misses it much. For most of its life, Tektronix focused on the second category: scopes, spectrum analyzers, video monitoring equipment. In this regard, Tek's main competition is themselves, which is a problem for them. Whether I'm a hobbyist or a pro, I can (and do) use an old 2430A DSO and 2467 analog scope to do just about anything I could do with a new $6K TDS3034B. That means that it's not really in Tek's best interest to support their customers in their efforts to keep the old gear alive. I think I am hearing from people who not only do not understand that "you get what you pay for," but have no use for the quality and accuracy of the products they are complaining about. If you actually read the thread, you'll see that folks aren't complaining about the *products* as much they are the company's support policies and decision-making strategies. Yes, it sucks that they no longer honor Howard Vollum's lifetime warranty on 535 power transformers. It sucks that I can't get a replacement U800 for my 2467. It sucks that they sold the chip foundry to a bottom-feeding IC company known for promising the moon and delivering press releases. But Tek is what it is. They still make good scopes, even if they aren't worthy of the kind of adoration from the engineering community that they used to enjoy. And their legal department is actually pretty enlightened when it comes to granting permission to reproduce out-of-print T&M manuals and documents. -- jm ------------------------------------------------------ http://www.qsl.net/ke5fx Note: My E-mail address has been altered to avoid spam ------------------------------------------------------ |

Isn't this where -- at least in the software arena -- the idea of maintenance contracts comes in? Granted, the average hobbyist is typically not going to buy into such a plan, but I would imagine most of Tek's sales are to companies that would be willing to pay, e.g., 10-30% of the original equipment cost per year for a guarantee that the equipment will be repaired free of charge if it breaks. The new equipment is so much software-based as well these days that Tek could also consider changing for software upgrades -- although personally I'm quite happy that TDS3000 software upgrades are free! I am going to get myself a nice 2465B or perhaps a 2467 after finish school and find myself a Real Job again -- in a sense those scopes seem like the pinnacle of pure-analog scope development and even if they are only good to 400MHz, there'll continue to be plenty of designs that can be serviced by such scopes for years to come. It sucks that I can't get a replacement U800 for my 2467. Ah, but wasn't someone mentioning that some third party is making compatible replacements? It was supposedly very expensive, but if one person can do it, surely others can as well -- and will, once there's some demand. Look at the old computers such as the Commodore 64 -- these days people enjoy not only completely emulating them in software (doesn't applies to scopes, obviously) but also building equivalent pieces of hardware in FPGAs (e.g., the Commodore One). ---Joel Kolstad |

I've seen lots of older 'scopes and other gear at the Tektronix company surplus store, mainly 7000 and 11000 series. I would be curious to know how much really is destroyed, and how much makes it into the store's inventory. Perhaps someone who actually works for Tektronix could comment? -- Dr. Anton Squeegee, Director, Dutch Surrealist Plumbing Institute (Known to some as Bruce Lane, KC7GR) kyrrin a/t bluefeathertech d-o=t c&o&m Motorola Radio Programming & Service Available - http://www.bluefeathertech.com/rf.html "Quando Omni Flunkus Moritati" (Red Green) |

It takes me 20 minutes to figure it out every time I turn it on, but I assume that's just because I don't turn it on frequently enough. There's another reason. For a long time, scopes were designed by engineers who used scopes daily, as their main tool. It wasn't any trick at all for them to select features that were useful, and operation that was intuitive. These days, the features are decided mainly by marketers and upper level managers, few of whom ever spent any time actually using a scope. They're implemented by software engineers, most of whom don't have the slightest idea what a scope does or how to use one. Consequently, we can look forward to a future of instruments that will be harder and harder to use and understand, and won't have the feature set the user really needs. I'll give you just one example, from the development of one of the first highly digital lines of scopes. A mock-up had been created out of some computer pieces, a display unit, and bits of this and that, so the engineers could get a sense of how the new instrument was to use. I sat down at the bench, and the first thing I did was to adjust the horizontal position. I turned the (only) knob clockwise, and the trace moved to the left. "Oh," I said to the software engineer who had implemented most of the functions, "I see you've got that backward, but that's easy enough to fix." "No," he said, "that's how I intended it to work. It's logical: the delay increases when you turn the knob clockwise." Pointing out to him that, logical or not, it would throw a barrier in the way of every person who ever used the instrument, had absolutely no effect on his certainty that his way was best(*). (And, yes, I would have made the exact same argument that turning the knob to the right *should* move the display to the left if the instrument were a spectrum analyzer.) In this case, the project manager was a former analog engineer, and he overruled the software engineer. But these days, most management positions are filled with people who have seldom or never actually used a scope, so more and more counter-intuitive, clumsy, and useless features are showing up. Get used to it. (*) In the '60's, when I was a technician, every place I went would have a bunch of Tek scopes and one or two HPs. The HPs were just fine, except that HP had insisted on making their own user interface. Where a Tek scope would use a knob, they'd use buttons, and so forth, and the controls were all put in different spots. We'd swear if we got stuck with using one of the HPs, since it would take so long to figure out where the needed control was and which way to turn it or which button to push. So no one ever recommended buying an HP -- we all wanted Tek scopes -- and as much due to familiarity as anything else. Then the Japanese scopes came on the market. Y'know what? The knobs and other controls were not only in exactly the same places as on Tek scopes, they were even the same shape and color. We could pick one up and begin using it right away. Y'know what else? Tek took a real beating from the Japanese scopes, way worse than they ever did from HP. Roy Lewallen, W7EL Tek, 1974-80, 1984-95 |

These days, the features are decided mainly by marketers and upper level managers, few of whom ever spent any time actually using a scope. They're implemented by software engineers, most of whom don't have the slightest idea what a scope does or how to use one. Consequently, we can look forward to a future of instruments that will be harder and harder to use and understand, and won't have the feature set the user really needs. I'll give you just one example, from the development of one of the first highly digital lines of scopes. A mock-up had been created out of some computer pieces, a display unit, and bits of this and that, so the engineers could get a sense of how the new instrument was to use. I sat down at the bench, and the first thing I did was to adjust the horizontal position. I turned the (only) knob clockwise, and the trace moved to the left. "Oh," I said to the software engineer who had implemented most of the functions, "I see you've got that backward, but that's easy enough to fix." "No," he said, "that's how I intended it to work. It's logical: the delay increases when you turn the knob clockwise." Pointing out to him that, logical or not, it would throw a barrier in the way of every person who ever used the instrument, had absolutely no effect on his certainty that his way was best(*). (And, yes, I would have made the exact same argument that turning the knob to the right *should* move the display to the left if the instrument were a spectrum analyzer.) In this case, the project manager was a former analog engineer, and he overruled the software engineer. But these days, most management positions are filled with people who have seldom or never actually used a scope, so more and more counter-intuitive, clumsy, and useless features are showing up. Get used to it. (*) In the '60's, when I was a technician, every place I went would have a bunch of Tek scopes and one or two HPs. The HPs were just fine, except that HP had insisted on making their own user interface. Where a Tek scope would use a knob, they'd use buttons, and so forth, and the controls were all put in different spots. We'd swear if we got stuck with using one of the HPs, since it would take so long to figure out where the needed control was and which way to turn it or which button to push. So no one ever recommended buying an HP -- we all wanted Tek scopes -- and as much due to familiarity as anything else. Then the Japanese scopes came on the market. Y'know what? The knobs and other controls were not only in exactly the same places as on Tek scopes, they were even the same shape and color. We could pick one up and begin using it right away. Y'know what else? Tek took a real beating from the Japanese scopes, way worse than they ever did from HP. =================== Roy , Tnx for your interesting comments. What surprises me is that ,as you highlighted , ergonomics no longer seem to be important in scope development. Whereas in other industrial activities and product design ,industrial designers pay a lot of attention to ergonomics. Perhaps it is that modern scopes (and similar equipment) are designed by nerds for nerds. It also adds to the perception that one has to be a 'specialist' to operate and use this type of equipment ,which I fear is an ever increasing element of modern marketing . A 'KISS' approach apparently does NOT bring in the $$$. Frank GM0CSZ / KN6WH This message sent a second time due to an earlier omission in the last line Please note the added word : NOT |

Bill and Dave saw the value but were committed to doing other things for their near future and suggested he start his own firm, giving him some advice along the way." Well, I have no "un-named" sources, only the named ones. For two interviews with Howard Vollum, co-founder of Tektronix, try: http://www.infoage.org/oh-howard-vollum.html Infoage is concentrating on the Signal Corps labs, most notably Camp Evans, NJ (outside of Fort Monmouth) which became the "Evans Laboratories," an adjunct of Fort Monmouth (along with Coles and Squires labs outside of the Fort in the 1950s). Vollum spent some service time at Camp Evans after overseas work on radar in Great Britain. Vollum's interviews consist of one in 1955 and another in 1980. There's some more at: http://www.ohsu.edu/vollum/about.htm There's also archive material from EE Times and several Tektronix collector's web pages. I don't find any reference to Hewlett-Packard, but more on the rivalry with Allen B. DuMont and his oscilloscope company. My own acquaintence is first with the 511AD model in 1954 while in U.S. Army and becoming a supervisor on microwave radio relay equipment. As far as I can recall, the sweep trigger of the 511 is little more than a Schmitt Trigger circuit which was rather common in pulse circuitry of the 50s. All of the first Tektronix scopes had regulated power supplies which enabled the stability of the vertical sweep to give true volts-per-graticule-marking information and for the sweep rate to be calibrated with some precision. Whether in service and maintenance or engineering design, the true information on the trace is more important than whether or not the sweep trigger is fancy (which it was, again, stable to use repeatedly thanks to the regulated HV supplies). Add to that the "unblanking" of the CRT while in sweep (blank screen during retrace) and the display is quite natural and easy to use. Having used a number of different instruments and scopes, I can't agree with the "standard control arrangement" comments. Each and every instrument has, to me, ALWAYS had some differences which required attention to the bell and whistle control lay-outs. This got worse by the 1970s when more and more function controls were added to the front panels and the sizes of controls got smaller and smaller. My fingers remained the same size...it got ridiculous with the pointy little "keys" of the optional 7000 series (?) plug-in for writing things on the CRT face...and the plug-in "spectrum analyzer" modules from a company that Tektronix acquired. Given the rather totally different function controls of today's DSOs, it boils down to everyone needing to understand their instruments FIRST before trying to use them. Ain't no such thing as "standard control arrangements" when the controls don't apply to newer functions. Len Anderson retired (from regular hours) electronic engineer person |

I know that I often pull the 20 MHz bandwidth limit switch on my 465B, just to quiet down the noise, and I actually have a 10 MHz scope which is still extrememly useful. It's nice to know that the extra bandwidth is there, but for almost any servicing job (TV, radio, CD, DVD, audio...) 50 MHz is way more than enough. - ----------------------------------------------- Jim Adney Madison, WI 53711 USA ----------------------------------------------- |
