I wonder if the Siglent 7000 uses metal inserts in their bosses, or did they cheap out.
I would expect metal inserts are again used on the 7000 as they have on many Siglent products.
Based on the pics privately shared, you now know the chassis of the DSO is a major structural component but of course that also requires to be secured to the front panel.
While Defpom didn't do a full teardown of this SDS2104X Plus, you can see the brass inserts clearly.
I would have expected LeCroy to use inserts on all of their plastic parts as well. Maybe in the future Siglent will provided detailed photos of what the 7000 series plastics look like on the inside. For now, they appear reluctant to provide anything. I am not really interested in other products Siglent has to offer at this time. I will say that from physically handling the 3000, it seems solid. That's just a feeling and have yet to take one apart. Outside of the Chinese only help, and the little snag with "importing" to save waveforms to memory, I have not heard anything bad.
Maybe worse... seasoned MEs were fed up, left and were replaced by folks that would play ball with the new directives (at half the cost, probably). Also, procurement department was tasked to look for cheaper suppliers of molded (but more brittle) plastic.
At work I don't see a single LeCroy without any sort of visible mechanical problem: knobs missing, cracked sides, etc. They are already rather old, but contemporary equipment from other brands always look much neater. They surely have QA issues for a very long time.
We have a lot of Agilent TE from that same era and they have mechanically held up well. My old Wavemaster's front plastic cover cracked last summer when I removed the dust cover. From what others have told me, this is a common problem with the Wavemaster and WavePro.
I don't know anyone that has outfitted a lab with Siglent but would sure like to hear from companies who have. We currently have that cheap Arb (almost ended all future Siglent purchases) and a few 3000 DSOs. The DSO's UI and encoders are having zero problems. Such a contrast from that Arb that couldn't make one encoder work.
We have not talked about calibration or service yet. With the large US companies, this was never a problem. The other difference is when we typically decide to buy TE, the local sales will get involved and do a demo. With Siglent, we just buy something and try it.
