Would anyone have a spare "Input Sensitivity" knob from either a 3580A spectrum analyzer or 3581A wave analyzer that has been removed from a parter unit?
I have experienced a rather surprising issue where the decal applied to the back of the clear skirt has started to disintegrate and fall off.? I applied a slight mist of fixative to hold the remaining characters in place but it was not compatible with the thin applique as much as had been expected.? For now everything is barely hanging on.
My 3580 was purchased in nearly new condition from a equipment rental agency years ago and I hate to see things like this happen to such a good unit.
Thanks,
Greg
