For sale is a HP 8596E Spectrum Analyzer. Last calibration was done in Jan 2011. I purchased this and other spectrum analyzers from a lab at a bankrupt formerly leading RF enclosure company ETC Lindgren. This analyzer powers up, as you see, and seems to respond to buttons. I guarantee that it powers up, however, it is sold AS IS in all other respects, as I am not set up to evaluate and calibrate those spectrum analyzers. Shipping cost reflects double boxing and the resulting size.
