COMES AS SHOWN! Acquired from a closed research lab which was recently closed, but equipment was still in use up until closure! High cost, high value equipment for a fraction of the new /replacement price. No accessories including standard power cord/cable. Due to the nature of vintage electronics, sold as is for parts or repair! No guarantees, no returns! May work perfectly or may need repair, we just do not know. 1. We are surplus equipment dealers and do not have the ability or knowledge to test equipment for functionality beyond plugging it in and describing what we observe as best we can.
