Tektronix 040-0413-00 is a modification kit for the 560 series timebase models 67, 2B67, 3B1, 3B3, and 3B4 for compatibility with 3L5 and 3L10 spectrum analyzer vertical plug-ins. This mod enables the sweep signal to pin 18 of the plug-in interlace to drive the sweep oscillator in the spectrum analyzer. This mod adds a resistor to the sawtooth cathode follower to drive the signal to pin 18 via a coax cable.
