Tektronix 5L4N spectrum analyzer 0-100 khz module and 5A18N dual trace oscilloscope module in Tektronix 5111 frame.  Very good condition, no major scratches or dents, paint and finish in very good condition.  Oscilloscope works both channels.  Spectrum analyzer is temperamental.  This instrument should be considered to need repair.  The tracking generator has output but does not display to the spectrum analyzer.  I would guess an input sensitivity issue on the spectrum analyzer but am not sure.  I have had the spectrum analyzer working as in the images, it is not at the moment.  I suspect a high resistance connection on an op amp or transistor. Almost all the transistors are socketed, easy to change but perhaps not the best design for long term reliability.   No International Sales please.
