If you get the "Sorry, the file cannot be displayed. There seems to be a technical issue ..." error when trying to view an image, a workaround is to click on the cog icon in the upper right side of the media viewer, and then select "Disable Media Viewer". We are aware of the problem and are looking for a solution.
The Tektronix 2642 "Personal Fourier Analyzer" is an FFT-based signal analysis instrument.
It contains a 16-bit arbitrary signal generator (0.5-200 kHz) and. two (optionally four) input channels with 12-bit (optionally 16-bit) ADCs followed by a 32-bit floating point FFT unit (up to 4K samples).
The 2642 has no operator controls, it is driven by PC software thorugh its RS-232 interface.
