Dear Dave,

Out from behind the rack rather than from the woodwork.
The 8642A Signal Generator has holes in the top and bottom covers- I have allowed 1U above and below for air intake- is this unnecessary?

As with everything else, use judgment. If there are vents, either they were there for good reason or they were specified in error, like someone being too paranoid. I don't have any 8642As, but if I did, I would err on the side of caution and leave that gap as you have.

I have 2 of these 8642A stacked on top of eachother on my shack table. They are both "feet-less", being ex-rackmount units. Never any problems with temperature rising too much. Mind you, these generators are MILspeced, max speced ambient temp is 50degrees C.
I gave up on working in my shack during last years heatwave, ambient was like 37C or so. The HP's could not care less.
