I recieved this piece of equipement as a gift, and it was used briefly as a spectrum analyzer only. I don't have the instructions, or original box. It was working the last time I used it, which was probably 2 years ago. Sold as is. Is in good shape, a few scratches here and there and it is dusty. Continental US only, paypal only, any questions just ask.
