[volt-nuts] 3458a with 202: Slave Test Convergence (sigh)

[new]

I know that HP will (gladly?) take your sick 3458 and bring it up to current specs, followed by a calibration. Since my sick one is at engineering level 2 or 3.something, it must be like it was built in 1989 - the dates on some components.

Should I try to do any troubleshooting, or just send it to HP?  

Will they upgrade the current (aged and pretty much not drifting) boards?

Or do they take a good board from their stock and replace the current board with one that may be new and 'drifty'?

I have read here that there are some unlisted upgrades that they do, also.

The RAM batteries will be replaced also, right? 

The biggest positive I see is the ability to go on the service plan and never have to worry about a failure again after the 3458 is brought up to current standards.
