content: I have an opportunity to pick up a Tek 11401 o-scope with a couple of useful plugins for a "reasonable" price, but I'm having some issues figuring if it's a good idea. I don't seem to be able to find any good objective discussions of how good these scopes are relative to other options (e.g. Tek 7k). I've got an 16700 logic analyser with a 16534a o-scope board, so I'm not desperate for a scope. I do mostly digital electronics below 250MHz (usually below 100MHz).Does the hive mind have any opinions on the following:Can anyone who actually has an 11000-series give an opinion?How does it stack up relative to the competitors (like 7k and 5k)?Apparently, it can use 7k plugins. Can it use any plugins, or are there some select list (that I can't seem to find)There's a sorta-kinda implication that there are "special" probes required for the 11k? Can you use "generic" probes or do you have to hunt down some unobtainium 11k specific probes.Many thanks for your guidance.

content: I am debating the same issue 7k vs 11k. I have the want for a high speed analog scope and am debating which model. I have two 7603 scopes so in some way I am already on the 7k path. The 11k series seem a little awkward, no?Last night I was checking the modulation envelope on a signal generator and it took a fair amount of screwing around to get the expected waveform. This was on a 3054b which is a decent scope. I also used my tds 784 with instavu and that took some triggering fitness as well.

content: Hey,I have both 7000 series and 11402 and the DSA602.What would I suggest?Go with the 7000 series.And get a newer 50 -100 mhz digital scope as soon as you can afford it for the storage and replay abilities.I have 7854 with storage but it is not the same as a modern digital scope with long playback.11000 series actually the one I am using is DSA602 is just too fing big and heavy, it sits under my desk most of the time.I mean big and over 80 lb.Has good features like seven auto measurements, self calibration but it only records a screen at a time.I purchased about 10 various 7000 plugins, which you will be able to find for as little as 25 dollars.The 7000 series is an easy to use analog scope system.Lots and lots of plugins are available.and everyone has great documentation available for each plugin.The 11000 series is impossible to find schematics or specific service manuals.I had an 11402 fail just 2 weeks after purchase and after 2 months of trying to find good data gave up and bought another unit. Wasn't worth my time to repair when a whole mainframe as it can be had for $100 without plugins.Actually people are almost giving all the 7000 and 11000 series away.Fixing an 11000 unit is not as rewarding as fixing the 7000 series.I am using the 7000 as a differential amp, as an XY scope for my curve tracer, as a 400mhz analog scope, some use them as spectrum analyzer. they are very versatile real time scopes.The 11000 series is not real time and mostly needs a continuous signal.Also the units are fairly voltage sensitive. some plugins have less than 10 volt maximum at the BNC.

content: A definitive list of what is available 7000 series..http://www.barrytech.com/tektronix/tek7000/tek7000scopes.htmlAlso 11000 Series:http://www.barrytech.com/tektronix/tek11000/tek11000scopes.htmlYou don't need special probes for 11000 but they did make probes especially for the 11000 that relay info to the main board.
