The Tektronix 7011-S is a spectrum analyzer plug-in module that extends the measurement capabilities of Tektronix 7000-series oscilloscope mainframes. Installed into a compatible 7000-series mainframe, it transforms the oscilloscope platform into a spectral analysis instrument capable of examining signal frequencies and their respective amplitudes across the frequency spectrum. The module integrates directly into the modular bays of 7000-series mainframes, leveraging the platform’s infrastructure to deliver detailed frequency-domain analysis.
