But all require line power. The practical difference is the TC 1000 weighs less than 10 pounds. The Interview 7700 weighs 27 pounds, and the HP 4954A, Tekelek Chameleon 8000, and last Idacom box I used were 40+ pounds. The Hard Engineering analyzer -- I don't have a contact, sorry -- is truly portable, at barely two pounds, but still needs line power. General Datacomm makes a very small blue-plastic battery-powered portable with an LCD display, but it is in a class by itself for limited functionality and bad price/performance. What makes the Hard Engineering analyzer so valuable for field work is that all you need for remote operations is a dumb terminal -- not even a VT-100.)
