The initial family [[introduced in 1969|introduction in 1969]] consisted of the 90 MHz [[7504]] and 150 MHz [[7704]] mainframes, | |||
and no less than 13 plug-ins − the [[7A11]] FET-probe amplifier, [[7A12]] dual-channel amplifier, [[7A13]] differential comparator, | |||
[[7A14]] current-probe amplifier, [[7A16]] singles-channel amplifier, [[7A22]] differential amplifier, [[7B51]] and [[7B70]] | |||
delaying timebases, [[7B50]] and [[7B70]] delayed timebases, [[7S11]]/[[7T11]] sampling system, and the [[7M11]] delay line. | |||
While the original [[7504]] and [[7704]] mainframes were short-lived, the series lasted until the early 1990s, | |||
with some of the original plug-ins like the [[7A22]] or the [[7S11]] remaining in production throughout. | |||
