content: Lecroy promised refresh of WaveSurfer 3000 series.Here it is:http://teledynelecroy.com/oscilloscope/wavesurfer-3000z-oscilloscopes/wavesurfer-3014zhttps://www.mouser.com/catalog/specsheets/teeldyne_wavesurfer3000z.pdfIn a nutshell, deeper sample memory (from 10MS to 20MS per ch), allegedly faster processor, and capacitive touchscreen....All in all, nice but nothing much....Waiting for a review...Regards to all.

content: I often wondered why Peak detect wasn't available in these and SDS3000 models like it is in all the other models that Siglent make.

content: Quote from: CustomEngineerer on April 11, 2018, 10:42:09 pmI don't think so. (He's already been seen browsing this thread.)Why ?Since WS3k and SDS3k were a collaborative effort by LeCroy and Siglent it might seem LeCroy didn't want/need Peak detect capabilities as it's not part of their offerings line up anyway.Maybe they think trigger capabilities, Persistence and colored intensity grading negate the need for Peak detect.

content: Display is 30% bigger then competitive offerings? what about R&S 3000 series? Guess they just count out whoever meets or exceeds their claims and they can all be true.

content: i'm sorry but 3014z is so... rigol-ycapacitive screen is a must if you ever used this scope, faster processor is a must too but how fast is faster? they need a very fast upgrade.. i see no new options so for now, meh. newest R&S are far more interesting i'm afraid

content: Quote from: maginnovision on April 12, 2018, 12:55:29 amAFAIK R&S RTB2000 and RTM3000 have the same 10.1" screen (with a high resolution). The price point will be interesting though. I think the RTM3000 is more expensive and the RTB2000 'only' goes to 200MHz.BTW: agreed on the missing peak-detect!

content: OK, my bad. Still with 1M Ohm only inputs getting 300MHz bandwidth is kind of wishfull thinking. Over 100MHz I rather use probes with a 50 Ohm interface towards the scope otherwise you don't really know whether what you see on the screen is due to the probe or due to the circuit.

content: I wonder... where does the update come from? I suppose it's siglent that updated the hardware? Because i know that lecroy doesn't care for this segment or they would release something that can actually compete with keysight and (now) r&s

content: I'm actually curious what will SDS5000X bring to the table... And don't say bugs, cause new products from A brands are also full of bugs lately.Rushed, rapid time to market product release schedules are everybody's problem.All of the 3000 series scopes from A brands are waay too expensive for what they give.Advanced math and triggers and basic serial protocols triggers and decode must be free on a 4000 USD 100MHz scope...Also, there is not a peep from Rigol as to where are they going from here...Their 4000, 6000 series is outdated and should be seriously upgraded to keep up with what is happening..Just hackability is not enough it this segment...

content: Quote from: JPortici on April 13, 2018, 06:30:01 amPossibly but the SDS3k webpage indicates it's still 10M/ch and there is also the chance that FW has freed up memory as V2 FW did in SDS2k models by doubling available memory from 35 to 70Mpts without HW changes.Maybe just with SDS5kX models not far away Siglent are keeping LeCroy on board with a tweaked WS3000 knowing SDS5kX will outperform it and instead of having to share worldwide sales in this segment Siglent can have a full slice of the action to themselves. They've got a better and stronger distribution network than they did when SDS/WS3k was first released.Interesting times.

content: Quote from: 2N3055 on April 13, 2018, 06:58:21 amTrue but the A-brands seem to be better at fixing them within a reasonable time frame and it usually are bugs which are much harder to spot.

content: Quote from: nctnico on April 13, 2018, 08:39:58 amExplain that to RTB2000... 😁Big companies also have very formal and rigid change management systems. So in reality, they are also very slow, despite professional effort.If you want very stable product, old platforms are that, stable (Keysight 3000 series is good example).They all need few years to make it very good. These devices are incredibly complex for anybody.Dont't get me wrong, I'm cautiously sceptical and don't expect miracles.But likes of Siglents and Rigols are getting slowly there. This new generation that will come out soon will probably be game changer..For instance take a look at Siglent SDS1104X-E. Out of the box that thing is more useful than stock DSOX3014T. DSOX3014T has no serial decodes and triggers, it has no 500uV/div front end etc. As a general purpose mixed signal troubleshooting tool it is miles better than scope 4 times it's price. Same can be said for some excellent GW Instek machines. Hell, even Rigol DS1000Z with it's very basic implementation of triggers and decodes will do something in a pinch. And on DSOX3014T set of basic decodes and triggers costs more than any of these scopes.And now take SDS1104X-E, and make it much better specs, bandwidth and such... And price it right... And than wait a bit until it stabilizes, software wise..RegardsSinisa

content: Quote from: 2N3055 on April 13, 2018, 10:35:10 amNot always. Keysight usually comes up with a test version to fix the most urgent problems quickly. The same goes for GW Instek. But yes, official release cycles are longer. Still there is a huge difference between how well firmware gets tested. Rigol and Siglent are pretty bad at testing firmware before releasing.
