TDS3000B Series Digital Phosphor Oscilloscopes Adapt to Wide-Ranging Video Measurement Needs
A Tell-All Tool for Video Troubleshooting:
Many video engineers have remained loyal to analog oscilloscopes, believing the gradations on an analog display are the only way to see certain video waveform details. The TDS3000B has the same information-rich display as an analog oscilloscope, but with much more detail. Tektronix DPO technology provides a live display that captures anomalies while providing the intensity-graded vision you need to interpret the waveform. Both patterns and one-time events are easy to see and understand. With up to 500 MHz bandwidth and four inputs, the TDS3000B family provides ample performance for analog and digital video use. The TDS3000B is compact and light enough to meet field requirements as well as design and evaluation needs on the engineering bench. Two optional video modules add easy-to-use, video-specific measurement and display tools to the TDS3000B DPO series.
