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.
