+The '''Tektronix Type K''' is a 30 MHz amplifier plug-in for [[500-series scopes]].
-Max sensitivity is 50mV/div, and bandwidth in a [[545]] is 30MHz.
+Type 53K/54K was designed by [[John Kobbe]], and [[introduced in 1955|introduced in March 1955]] along with the [[541]]/[[545]]. In August of 1955, just five months after introduction, it was renamed Type 53/54K, and in 1959, when the 541A/545A mainframes came out, it got its final name, Type K. It was dropped after 1970, with [[L|Type L]] replacing it.
-Type 53K/54K was [[introduced in 1955|introduced in March 1955]] along with the 541/545.
+The name was deliberately chosen to be halfway into the alphabet.  Slow plug-ins would use A-J and fast ones L-Z.  This idea never went anywhere.
-At that time, it was the only plug-in that could utilize the
-new mainframes' speed; the redesigned Types [[A]], [[B]], and [[C]]
-weren't ready until August 1956.  In August 1955, just five months
-after introduction, it was renamed Type 53/54K, and, in 1959,
-when the 541A/545A mainframes came out, it got its final name, Type K.
-It was dropped after 1970.
-Type K was the fastest of the single-channel plug-ins.

-and did not exceed it until Type [[1A1]] in 1964.
-Earlier single-channel plug-ins had two inputs and a
-switch to select between them, making it convenient
-to probe two test points at once.  The Type K design
-could not tolerate the extra stray capacitance,

+At the time of introduction, it was the only plug-in that could utilize more than half of the new mainframes' speed − the [[A|Type A]], [[B|Type B]], and [[C|Type C]] upgrades weren't ready until August 1956.

+Type K was the fastest of the single-channel plug-ins, and the first plug-in to use [[T-coil|T-coils]].  Tek did not equal it until [[L|Type L]] in 1957, and did not exceed it until [[1A1|Type 1A1]] in 1964.
+Earlier single-channel plug-ins had two inputs and a switch to select between them, making it convenient to probe two test points at once.
+The Type K design could not tolerate the extra stray capacitance, and the feature was dropped, never to return.
+(Exception: the [[7A16P]], which has two input connectors and provides the ability to select which one is fed to the amplifier.)
+Late versions had a [[BNC connector]] instead of a [[UHF connector]].
+Types K and [[G]] are the only letter-series plug-ins
 where the Gain vernier is not concentric with the step attenuator.
