7854 FEATURES The TEKTRONIX 7854 Oscilloscope with Waveform Calculator combines the features of a high-performance plug-in oscilloscope with a waveform-oriented dedicated-function digital processor. The waveform processor provides equivalent-time sampled digitizing of waveforms to 400 megahertz equivalent-time bandwidth The processor can be operated from either keyboard (front-panel measurement keyboard or detachable Waveform Calculator keyboard) or remotely over the GPIB (General Purpose Interface Bus). Programming, consisting of a series of commands stored for later execution, is available to simplify measurements which must be repeated Editing and execution is controlled either from the Waveform Calculator or the GPIB
