The Type 585 is a 100MHz oscilloscope introduced by Tektronix in 1959 and made through the 1960's. The 585 uses 80-series plug-ins, which look like 1-series and letter-series plug-ins but are electrically different, primarily in the impedance of the signal interface between the plug-in and the scope. The Type 81 adapter allows the use of letter-series and 1-series plug-ins in a 585. The 585 has tunnel diode triggering and, like many Tek scopes, a distributed amplifier for vertical deflection. A Type 585A also exists.
