This is a used Tektronix 465 oscilloscope, that has been partially tested using the rear triggering port. Physically in great condition. Trace 1 works well, Trace 2 appears on screen, but there does not process the waveform. If there is a particular test you want me to perform, I have a signal generator. Just send me a message. I will update as I get more time to test it. Otherwise, sold as is
