The Tektronix 160 series is a modular oscilloscope from the early 1960's. A 160 system typically includes a Type 160 power supply, a Type 360 indicator unit, and one or more of the 161, 162, and 163 trigger and sweep modules. Power connections are made behind the modules using cables that have octal connectors. Signal connections are made on the front, typically with banana plugs. The 160, 161, 162, and 163 use the ceramic strip and silver solder construction style that is prevalent in other Tektronix equipment of the era, such as the 500-series scopes. The Type 360 indicator unit contains its the CRT power supply and the vertical amplifier and is constructed using a single-sided printed circuit board.
