1. Well, I am in northern Germany and Keysight has an Office in southern Germany, so may be 700 km away
-Shipment is usually UPS or FEDEX
2. I send them an email and get a RMA usually the same day
3. I don't think I ever bought equipment directly from them, except repair parts. Usually I buy Keysight equipment from:
- Distributor in Germany
- Keysight eBay store
- Used from around the world
4. No personal contact to the German Keysight office
We also used to have very good support in Germany for FLUKE, KEITHLEY and TEKTRONIX, up to like 10 years ago.
That has changed so much to the worst ever experience, since they all merged and centralized everything.
The last time I needed help with a Tektronix scope, I did not even get an answer form the support team in Germany.
