The '''Tektronix Type D''' is a differential amplifier plug-in for [[500-series scopes]].

~~It has~~ high gain~~, and~~ the bandwidth depends on the gain, ranging from 2 MHz at 50 mV/div ~~and up,~~ to 300 kHz at 1 mV/div.

Type D was the first high-gain plugin for the 500-series.

The bandwidth depends on the gain, ranging from 2 MHz at 50 mV/div to 300 kHz at 1 mV/div.

There are two axes of sensitivity setting: a decade attenuator in front of a gain switch.

This scheme would be reprised in Type [[W]].

It displays the difference between two input signals, with a common-mode rejection ratio of 10,000. It has

six tubes, on a shock-mounted subchassis to avoid microphonics.

Type D was [[introduced ~~in 1954|introduced]]~~ with the [[531]] and [[535]] in [[introduced in 1954|1954]] as Type 53D.

Along with Types [[A]], [[B]], and [[C]], Type D was introduced with the [[531]] and [[535]] in [[introduced in 1954|1954]].

It was briefly renamed ~~Type~~ 53D/54D in 1955 with the introduction of the [[541]] and [[545]],

and then quickly ~~renamed Type~~ 53/54D.

At the time it was called Type 53D.

~~Its name was then shortened~~ to ~~Type~~ D in 1959 with the introduction of the 5xxA scopes.

It was briefly renamed 53D/54D in 1955 with the introduction of the [[541]] and [[545]],

Its ~~last~~ year was 1968~~, having~~ been superseded by ~~the constant-bandwidth model~~ [[1A6]].

and then quickly changed to 53/54D, shortening to just "D" in 1959 with the introduction of the 5xxA scopes.

Its final year in the catalog was 1968; it had been superseded by Type [[W]] and then [[1A6]].

[[K]], [[L]], and [[T]] are tied for longest production life, at 16 years.
