The '''Tektronix 7A24''' is a 400 MHz dual-channel vertical plug-in for [[7000-series scopes]] with (fused) 50 Ω [[BNC]] inputs. It is the fastest multi-channel plug-in available for the 7000 series. Unlike most other plug-ins, it does not offer AC input coupling. | |||
A single-channel version was planned as the [[7A25]] but did not make it into production. | |||
The 7A24 would typically have been used in [[7834]], [[7844]] or [[7854]] mainframes. | The 7A24 would typically have been used in [[7834]], [[7844]] or [[7854]] mainframes. | ||
