Fuse Change in HP33120A Function Generator

Simple post. Most of the function generators that we have here are fitted with a fuse holder that allows us to quickly swap out busted fuses. This one in particular however is not.




Changing the fuse in this one is about just as simple except you have to take it apart before you can change it out. I just thought it would be neat to show the guts of the function generator.

The photo below and to the left is just the new fuse in the sockets. It looks like a goofy looking resistor.

The photo to the right is measuring the resistance of the old busted fuse. It's measuring 6-ish Megaohms which doesn't make for a very good fuse.
