The '''Tektronix 455''' is a 50 MHz dual-trace solid-state portable oscilloscope. | |||
It is functionally similar to the [[453]] and can be seen as its successor. | |||
The 455 makes extensive use of integrated circuits and is smaller and lighter than the 453. | |||

==Internals == | |||
The final stage of the 455 vertical amplifier employs a differential pair of triple-stacked NPN transistors. | |||
The purpose of the stacking is to get higher voltage swing and to eliminate the need for a heat sink. | |||
The 455 uses a linear power supply. | |||
Triggering is done with [[155-0121-00]] chips, one per channel. | |||
