If you were a marketing guy, you would see that bit of data, and discourage the suits from wasting resources on a logic analyzer group. As I said earlier, John and I started Tektronix-Logic-Analysers,

I'm pretty sure I didn't say they were *totally* useless ;-) Just not all that useful most of the time. Mine would come off of the shelf more if it was more useful to use it, than to use other ways. W

I am co-owner to Tektronix-Logic-Analyzers, and it just never lit. I don't recall there being more than a couple of pictures to transfer over to groups.io, so it was deemed not worth the cost. Everyth

You are aware that the polarity marker on tantalum capacitors is always the "+" terminal, right? -Chuck Harris David Kuhn wrote:

The 11801C specifically calls on the calibrator to be 250ps risetime. I'm sure that I got the information about the 25ps risetime calibrator being an option from one of you on this group. Maybe Leo? I

I'm pretty sure that the 20ps calibrator is an option available on the entire series, and standard to none. -Chuck Harris Reginald Beardsley via groups.io wrote:

From what I remember, one special option of the 11801 came out with a calibrator that was half of the S26 TDR head. It has a 20ps calibrator. It can be recognized by its gold APC-3.5 connector... wher

It is important that you remember your 11801 is not an ordinary digital storage scope: It is a sampling scope. Sampling scopes do their magic by taking small samples of hundreds, or even thousands of

That is an IEC connector.... just not the type you are used to. It is known as a Mickey Mouse connector because of the profile. -Chuck Harris Jim Ford wrote:

Jeff, I think if you explore this further with your customer, you will find he doesn't have a 485 at all, but rather has one of the similar looking scopes, the 453, or 454. -Chuck Harris Michael W. Ly

Once tek got out of the introductory 7504, and other sub 100MHz models, they boosted the 7000 series 4 slot frames up to 200MHz minimum. I don't think they could have achieved a large screen model CRT

When you are tweaking the 2465's vertical amplifier networks to perfect the transient response, you can get into an area where the pulse looks very nice and flat, with few ripples, but, if you do a qu

Exercise 05 only tells you the number of hours the scope has been run since its last calibration. Most calibration houses follow tektronix's lead, and reset this value to zero during calibration. P6-1
