The Type 53C is a dual-trace plug-in for [[500-series scopes]]. | The '''Tektronix Type 53C''' is a dual-trace plug-in for [[500-series scopes]]. | ||
It was [[introduced in 1954|introduced]] along with the [[531]] and [[535]] mainframes in 1954. | It was [[introduced in 1954|introduced]] along with the [[531]] and [[535]] mainframes in 1954. | ||
It is very possibly the first dual-trace scope or plugin ever. | |||

the | In the 53x scopes (Tek never documented its performance in the 540's), its bandwidth is 8.5 MHz, and like most letter-series plug-ins, its maximum vertical sensitivity is 50 mV/div. | ||
bandwidth is | Unlike the Type [[A]] and Type [[B]], the Type C had the ability to invert the signal before display. | ||
Type 53C was replaced by Type 53/54C in [[introduced in 1956|1956]] when the [[541]] and [[545]] were introduced. | |||
The Type 53/54C's bandwidth is 24 MHz in those scopes. In [[introduced in 1959|1959]] it was replaced by [[CA|Type CA]]. | |||

At 15 tubes, the Type 53/54C and Type CA have the highest tube count of any letter-series plug-in. Each channel consists of a [[6AK5]] cathode-follower driving a [[12AU6]] differential pair | |||
which drives a [[6AU6]] differential pair. | |||
The two channels converge on a [[12AT7]] cross-coupled cathode-follower. | |||
Four more tubes, a [[6AL5]] and three 12AT7's, comprise a logic circuit which determines which channel drives the output at any given moment. | |||
The options are A, B, CHOPPED, and ALT. | |||
