The Tektronix 7854 is a 400 MHz mainframe oscilloscope with integrated analog and digital storage, microprocessor-based waveform processing, and GPIB control for signal analysis across research, production testing, and educational environments. It accepts Tektronix 7000-series plug-ins to extend measurement capability to 14 GHz in equivalent-time sampling mode, delivering 10-bit vertical digitization with 0.01 div resolution and storage for up to 40 waveforms at acquisition depths from 128 to 1024 points. Advanced triggering, onboard signal processing including averaging and mathematical operators, and programmable waveform computation make it suitable for complex signal characterization in RF, microwave, and digital domains.
