Yes, of course! (Face palm!) I own a 437B power meter, a 11720A pulse modulator, a 5316A frequency counter, and two 11713A attenuator/switch driver boxes (one in use, and one is the parts mule), all 2 RU high. I haven't stuck them in the microwave rack in my garage yet because 1) I haven't decided if I want to take up rack space yet, and 2) I don't have the rack ears and hardware to put those half-rack width boxes together yet.

I was moving stuff around on the bench and accidentally yanked on the cable running between my only 11713A at the time and an 8494 or 8495 step attenuator, probably 9 months ago. Broke a pin off the Viking connector and rather than trying to find a new connector, I just bought another 11713A on ebay for about $40. Those things are cheap and available these days. So the one with the busted pin is now a parts mule.

Ah, another thing to know about 19 inch racks is the support angle brackets along the sides, although somebody partially covered the subject already. I didn't know anything about those until recently. Yes, heavy test equipment needs angle irons along the sides, bolted onto the side panels. Lightweight audio gear with limited depth, not so much. Rack ears are special angle irons that bolt onto the sides of the piece of equipment at the front, and then bolt onto the rack at both sides. For heavy TE, they only serve to keep the box from moving, but in the case of shallow, lightweight audio boxes, they could support the entire box. Rack ears may or may not be compatible with the handles that one would want to attach if just stacking TE on a bench or cart. HP gear does have handles and rack ears that work together, at least the 8566 spec an and 8530 sweep oscillator. Handy to keep the handles on there, should rearrangement be necessary.

HTH.
