I have a 3457A which does not get a lot of use, but it has not been calibrated for years, and I need to get it calibrated as I need to make some measurements of greater accuracy than usual. The 3457A is scheduled to go to Keysight a week from today. I'm wondering if its best to keep it powered up until then, to let the reference stabilize somewhat. Or it is a bit late for that now?
I have asked Keysight to change the battery - I'm led to believe that Keysight will do that as part of the calibration unless the battery is particularly expensive. When I last looked, I could not find a suitable battery in the UK, and those in the US could not be shipped here. But that was a few years ago, so maybe things are different.
