This item is a Tektronix TDS754D Digital Phosphor Oscilloscope (DPO) in excellent cosmetic and working condition. The original cathode ray display has been replaced with a flat panel LCD display upgrade. These oscilloscopes typically have problems with the old cathode ray displays gradually fading out and becoming unreadable as they age. With the installed LCD upgrade, the display will remain sharp and bright for the life of the instrument.

This oscilloscope is fully functional and passes all the built-in self tests. It seems to be pretty accurate as far as displaying the correct amplitude, time, and frequency information, but it probably needs a calibration to guarantee accuracy to the published specifications. There is no calibration sticker on this unit and I have no idea when it was last calibrated. I have had it in my lab as a backup scope for the past several years, and have used it so little I think it is time to pass it on to someone else that will get more use out of it.

The oscilloscope comes with a snap-on front panel cover and a power cord. Anything else shown in the photographs is not included with this auction.

Note: The LCD display upgrade on this unit uses the external VGA port that is normally available on the rear of the TDS754D oscilloscope, so this external display feature is no longer available on this oscilloscope.

DIGITAL PHOSPHOR OSCILLOSCOPE (DPO)

DPOs capture, store, display, and analyze, in real-time, three dimensions of signal information: amplitude, time, and distribution of amplitude over time. The benefit of this new third dimension of information is an interpretation of the signal dynamics, including instantaneous changes and the frequency of occurence displayed in the form of quantitative intensity information. The resulting information-rich display enables the user's eye to integrate the subtle patterns and variations of actual signal behavior.

DPOs also offer enhanced color grading to display historical information that has been acquired over time. This allows an extremely powerful visual display where colors show relatively how often random events occur, which is especially useful for communications mask testing.
