Just a quick update on Keysight's customer service. I just called, since they never called me back.
Bottom line, they will not assist, period. I'm on my own, 60 days out of warranty.
They denied knowing anything about 'corrupt nand', said there is no service note, and there is no 'known defect' of that type with any model.
When I asked about paid repair options, they demanded to see my origianl invoice, depsite purchasing the scope from Newark, and registering it with them the day it arrived, and purchasing numerous options that Keysight had to process.
Never again. A $5000 paperweight they refuse to repair. For what it's worth, don't tell them you are an individual, you MUST be a company if you want decent customer service. The moment I told them I had no company name, this was my personal scope, their attitude immediately changed from eager to help to suspicion. What the hell happened to Keysight?
