The Tektronix 549 is the only storage scope that takes a letter-series or 1-series vertical plug-in. It was | The Tektronix 549 is the only storage scope that takes a letter-series or 1-series vertical plug-in. | ||
It was [[introduced in 1966]] and discontinued in 1972. The vertical -3dB bandwidth is 30MHz. | |||
Like many Tek scopes from the period, it uses a mix of transistors and tubes. For example, consider the buffer amplifier in the 549, whose purpose is to interface the high-impedance output of the plug-in with the low-impedance of the 200 nanosecond delay line in the 549. | Like many Tek scopes from the period, it uses a mix of transistors and tubes.
