Working fine Tek 2440. Last calibrated (and maintained) April 14th 2014. If you need/want fresher calibration, I can take it to ebay seller '2465b', aka Alex Schonfeld. but you'll have to pay $150 more (for his cal fee), but these scopes rarely drift out of cal in just 1 year. Last cal (a year ago) included replacing lithium batteries which reside inside 2 NVRAM ICs.   Will include power cord, instructions on a CD (not pictured), and 2 Tek P6133 150MHz 10:1 probes with readout encoding (shown; faster probes can be found on ebay, but even 300MHz probes won't show more than about 100MHz nicely unless 6" alligator grounding path is shortened. Best hi-freq fidelity is obtained when a 50ohm source is driving inputs thru 50 ohm cable(s) and the scope's 50 ohm termination(s) engage). Scope runs on 115 or 230 volts. Cosmetics are all around excellent.   This is a 300MHz digital storage scope, from around 1990, which seems some refer to as the end of the repairable scope epoch. Serial # is B013908. It is guaranteed to work correctly, or you can return it within 14 days for refund. My $800 price is miniscule (1/15th) compared to what it cost new, and less than what you'd pay others for a guaranteed good one (but slightly more than you'll pay for one begging for repairs while pretending not to).      Posted with eBay Mobile
