    Note: The 5SP7 cathode ray tube has 2 independently aimed electron guns
    ,
    that can each draw different traces simultaneously
    .
    The '5' means it has a 5" diameter screen, the 'S' denotes the type, and the 'P7' means it has radar-style
    long persistence phosphor
    that glows bright blue briefly and fades to a
    yellowish color lasting 1.5 seconds before going dark.
