content: OK, so i was on Amper Faire (www.amper.cz), and there were some new oscilloscope brands i´ve never heard of!The brands are Teledyne LeCroy and ROHDE & SCHWARZ. There was Keysight as well, where i nad my friend spent most of the time just playing with their oscilloscopesUnfortunately I don´t have money to afford it, so i can´t do a review, but i would like to see Dave what he´s gonna say on them...They do seem well quality, but only ROHDE & SCHWARZ scopes are touchscreen but they don´t have the zone triggering featureHave you heard guys about these brand of scopes or even have one of them?Anyways I really enjoyed the Faire

content: Teledyne Lecroy make the world's fastest oscilloscope (or so they claim,), and Rohd & Schwarz are a big name too. Along with Agilent and Tektronix, you've just named the big 4 high-end oscilloscope makers.

content: Both TeleDyne LeCroy and Rohde & Schwarz are two of the oldest and best known scope manufactures in the world (After the likes of Tektronix and HP/Agilent/Keysight).LeCroy have been around since the early 60's. I used LeCroy up to the late 90's and they were top end devices back then, but I've never tried their latest offerings.Rohde & Schwarz are even older, dating back to the 1930's and are also the company behind Hameg since 2005.McBryce.

content: Quote from: angelioto007 on March 26, 2015, 12:40:18 pmRohde & Schwarz (a German company) is has been around for over half a century, and are very well known for their signal generators and communications equipment. R&S bought the German manufacturer of low end scopes Hameg around 2005 and continued to sell their scopes under the Hameg brand (which is now replaced with the R&S logo), but R&S themselves only started making their own mid-range scopes around 2010 if I remember right.LeCroy is one of the pioneers of digital scopes, and essentially are to digital scopes what Tek was to analog scopes. If you want the fastest and most advanced scopes then it's usually LeCroy or nothing else. However, their low end scopes (WaveAce) suck.QuoteLeCroy has touch screen scopes since 2001, and all their scopes aside from the very low end (the crappy WaveAce) are touch screen scopes.

content: Quote from: Wuerstchenhund on March 26, 2015, 05:21:10 pmQuoting an OM ham: "R&S never made anything low end, ever."Well, okay, now with the acquisition of Hameg they actually do, but that's another story.Also, there are no vintage R&S scopes, because R&S distributed Tek stuff in Germany / central Europe. But you can often find (at least in Germany) Tek scopes with R&S Vertriebsgesellschaft (R&S distribution company) stickers on 'em.(And they're actually closing in on getting a century old. They're founded in '33, I think.)Regarding LeCroy, it's pretty safe to say that the majority of older DSOs that have a competitive feature set comes from LeCroy. High real time bandwidths and deep memory were actually there in the mid to end of the 90s... 9300, LC, LT series.

content: When I worked at Tektronix I was "brainwashed", mainly by marketing, into believing that Lecroy scopes were crap. Having never used one I took them at their word. My next job after Tek was with a company that used Lecroy scopes almost exclusively, and very quickly I was able to be "deprogrammed." The high end Lecroy scopes are great and offer a good user experience.

content: Quote from: tautech on March 26, 2015, 09:55:48 pmNot really. They have good scopes, but neither bandwidth nor performance are anywhere close to "high end".Quote from: nctnico on March 26, 2015, 10:09:34 pmThe same is true for Iwatsu. In fact, their scopes are pretty dated by today's standards.

content: YEW/Yokogawa scopes are more blown up (bandwidth wise) versions of their scopecorders / analyzers. Which are the best in the industry. (In fact, they essentially invented and innovated them. Just like LeCroy did on the other end of the bandwidth spectrum)The time-nuts might take an interest in their time analyzers, though. Not really on par with the best of the best but very high level anyways. Also, power analyzers.

content: The Iwatsu TS-81000 is interesting for its very high updating speed and persistence ability. Unlike other brands of "DPO"s, it uses a real CRT internally that it scans into a digital LCD display. Overall bandwidth is only 1GHz, which is not competitive for the price.

content: Quote from: angelioto007 on March 26, 2015, 08:40:13 pmThose scopes are pretty crazy. I actually saw one in person on Tuesday at OFC. The folks at the Lecroy booth had it set up to receive a 50 Gbit/sec bitstream. Lots of other really sweet gear at that conference, that's for darn sure.

content: Quote from: firehopper on March 27, 2015, 12:11:23 amProbably more a case of when you realize how much it costs you simply go elsewhere, as their RTO/RTM/RTE scopes are pretty expensive when compared with other big name brands. Considering that R&S is still pretty new in the mid-range/high-end scope business I'm not sure the pricing is really appropriate.

content: Quote from: dom0 on March 27, 2015, 09:27:58 amAlso, in the '70s, Tek had some "transient digitizers" with an internal storage CRT that was read out slowly into a digitizer. A short-lived technology, based on "scan converter" tubes.

These are also the only companies at the moment manufacturing scopes with a bandwidth of >10 GHz.And here are good starting points for your list:A list of oscilloscope manufacturers (devices with >100 MHz bandwidth):http://oscopes.info/market/3-oscilloscopes-products-and-suppliersA list of oscilloscope technology milestones:http://oscopes.info/basics/2265-oscilloscope-milestonesWe are still working on both lists.
