The Tektronix 11402A is a 1 GHz digitizing oscilloscope built on a modular mainframe architecture that accepts 11000-series plug-in modules for flexible signal acquisition and analysis. This instrument captures up to eight input channels with configurable sampling—300 MHz bandwidth across all eight channels, 600 MHz across six channels, or 1 GHz across three channels—making it well-suited for multi-channel transient and repetitive signal measurement in laboratory and production environments.
