I've got a rack of equipment that sometimes requires a special calibration where I need to lug over a signal generator. Of course the only ones we have available that go to the necessary frequency weigh like 50lbs. I've recently been eyeing a little gadget that costs about 1/10 or 1/20 the cost of the Keysight units, interfaces using USB oe Ethernet, and is about the size of a deck of cards. The accuracy isn't perfect on its own but that's what a 10MHz ref clock is for. It's amazing how far tech has come and it's amazing how much we are still paying for these dinosaur pieces of test equipment.
