The second question is condition. In this case "As Is" "No Returns". We have done our best to describe the issues, but please ask questions before you bid. We view others with a passion for Test and Measurement as part of a very special community whether a hobbyist or Noble Price level Physicist and will do our very best to treat any buyer the way we would like to be treated ourselves. All we ask is you treat us fairly and we will always go the extra mile even beyond eBays requirements and our stated warranty to take care of any legitimate issue - whether a performance issue or simply not the instrument that best serves your needs. Again we encourage you to contact us before you bid with any question on the capabilities, condition, and perhaps most importantly if it is the right product to meet your specific needs. About Us: Ascent Concepts and Technology (ACT) and our new Phoenix Metrology Research Group is a few scientists and engineers involved in R&D of Time and Frequency as well as Voltage Metrology Instruments intended to bridge the ever widening gap between Quantum Standards and current State of the Art calibration and measurement instruments. Basically a bunch of Test and Measurement nerds. We find buying and selling equipment a nice compliment to our R&D work. "To be is to do" Socrates. "To do is to be" Jean-Paul Sartre. "Do be do be do" Frank Sinatra.......Proof of de-evolution? International Buyers: Our official policy is no international buyers, If we make an exception please be aware buyers outside the continental USA are purchasing strictly "As Is" "No Returns" with no warranty expressed or implied International buyers must arrange their own shipping.
