The '''Tektronix 11A81''' is a 3 GHz single-channel amplifier plug-in for [[ | The '''Tektronix 11A81''' is a 3 GHz single-channel sampler/amplifier plug-in for the [[11403A]] and the [[CSA404]]. | ||
The 11A81 receives an "acquisition strobe" signal from the mainframe, and samples the input signal. | |||
The sampled signal is fed to the mainframe, where it is digitized and displayed. | |||
This architecture allows the 11A81 to provide higher bandwidth than the 11k plug-in to mainframe signal path. | |||
Development of the 11A81 was managed by [[Murlan Kaufman]]. | |||
A [[165-2448-00]] (U950) diode bridge IC is used for over-voltage protection. | |||
A [[165-2392-00]] (U650) H2392 sampling bridge performs the sampling. | |||
