Using Oscilloscopes to Test and Debug Analog HDTV Signals

Applikationsberichte

Today’s consumer electronic designers must be proficient mixed signal designers. Many devices have a combination of analog (audio, video) and digital (HDMI, DisplayPort) interfaces. A composite video input and/or output is still the lingua franca (working language) of consumer electronics video devices. If a device has one, and most do, it is an excellent way to quickly verify its correct operation, but you must have the right oscilloscope.

The 4000 X-Series oscilloscope’s 1 million waveforms per second update rate is able to plot all lines, creating an intensity graded image with details from the many different lines that are readily apparent. Color bursts, sync pulses, color bars and flat field are all visible. Lesser oscilloscopes may not keep up with the information available.
