CHECK OUT THE WIKI The purpose of the wiki is mainly to allow you to find information on instruments, either from either
- The model number
- The function(s) listed below. Some instruments have multiple functions - for example, the 4195A is a VNA, spectrum analyzer and an impedance analyzer. Therefore the 4195A is listed in multiple categories

Re: HP 141T Power Supply Help Needed
At about 1.30am, the fan slid out enough to access the mosfet pins. A little tweaking and in next power up I see way more sane voltages on the transistors. 23.5v is gone. 1.5v to the driver base etc.

Re: Keysight customer support policy
I have had bad results as far as leakage with Duracells, but Ray O Vac has been far worse. Once they are 2 or 3 years old, there is a serious risk of them leaking in the package. Mallory Duracells
