BK Precision 2559 Digital Storage Oscilloscope 300MHz 2GS/s 4 Channel USB LAN
Used see photos. Tested, all channels working. Does not include test probe or power cable.
One knob is missing, it is the upper left "select" knob. Still works fine if you just turn the pot by hand. Also the display has a defect on the left-hand side and is somewhat dim, but still works. See photos for details.
