A lot of test equipment products have the "port" for the standard
notebook security cable (I think Kingston originated it, but there are
plenty of knock-offs floating aboot).

Ah, you mean "Kensington". A brand-name that's become a standard.

They look very feeble to me. I never tried yanking on one to
destruction, but I find it hard to believe it wouldn't simply
snap the T-piece off the lock.

Sun Microsystem's desktop kit used to have a small (1cm) cube
of metal on the back with two holes drilled through the center.
One hole allowed you to screw the cube to the rear case (the
back of the hole was a smaller diameter to be clamped by the
screwhead). The other hole allowed you to pass a steel cable
through the cube, which when fitted, covered the screwhead so
you can't unscrew the block. I think the block fitted in a
slight recess in the case so you couldn't twist the block
itself to try and unscrew it (a locknut would do the same
if there was no matching recess).

Yes, I'm sure you could yank hard enough and pull the cable out of the
equipment. This was designed to secure laptops, not spectrum analyzers.
If you yank the Kensington cable hard enough to pull it free from a
laptop you will destroy the laptop case and likely some of the
electronics inside. If the bench equipment is made anything like the
stuff I've seen from HP and Tek, it would just enlarge the hole the
cable fits in and do little other damage.
