I would not bother starting this topic, if the customer whom reported his dissatisfaction about Rohde & Schwarz he was not a European (Ireland).
Unfortunately for him, I am much more aware of
Rohde & Schwarz past history as a company.
Rohde & Schwarz from the times of analog TV transmitting systems, the company was bonded as supplier of test equipment at government managed organizations (National Television / government owned or private owned TV stations).
While the company in the past decade, it did release a small number of models as consumer level Oscilloscope, the R&S management core policy,
this never changed.
https://www.eevblog.com/forum/testgear/why-you-should-think-twice-before-buying-a-rohde-schwarz-oscilloscope/Yes, any factory or a brand, it does deserve the right, to select the market which will deliver their products.
Consumer level? , B2B? Mixed?
Military industry only?
At 2025,
Rohde & Schwarz make it clear once more time, your only source for product support, this is the network of their authorized distributors.
Even if you simply need a Firmware update file, or even product documentation files.
Long story in short, especially when you are buying any
used R@S gear, you are all alone.
Rohde & Schwarz never gained in
Greece, any share of retail market.
They had only listed a telephone number, if some one cares to call them.
In conclusion, if you do not have an easy access in your location, with the network of their authorized distributors, then you better avoid them.
