The Tektronix TDS3032 Color Digital Storage Oscilloscope 300 MHz, 2.5Gs/s is one of the most portable Digital Phosphor Oscilloscopes (DPOs). Digital Phosphor Oscilloscopes have an intensity graded color display that provides information about the frequency of occurrence of signal amplitudes and widths. This helps the user locate and characterize waveform anomalies that can be elusive on traditional Digital Storage Oscilloscopes. The fast update rate of DPOs also makes it easier to capture and display infrequent waveforms or waveform variations. DPOs deliver a new level of insight that makes dealing with complex signals simple. DPOs display, store, and analyze, in real-time three dimensions of signal information: amplitude, time, and distribution of amplitude over time.
