The Leader LV5750 is a new paradigm in portable digital testing. This multiformat HD-SDI and SD-SDI monitor features a color XGA (1024 x 768) LCD screen waveform monitor for signals. SDI inputs support auto detection of twenty standard formats. Selected SDI input signals are reclocked and output to an active serial output. Complete digital processing of SDI signals enables highly accurate measurements. Test modes include waveform, vector, picture, audio, and status displays with time code. Displays and sub-displays can be viewed in various combinations side by side or as a four in one multi-display. A composite signal conversion converts SDI component signals into pseudo-composite waveform or vector for NTSC or PAL. Vector shows chrominance difference signals in vector format with the amplitude settable as variable, IQ-MAG, or x5 times. Line selection with strobe of the same line can be displayed in picture, waveform, vector and data dump with values in hex or binary notation eases analysis. Complete protocol test and analysis functions are provided. Variable vector gain includes onscreen readout for optimizing digital camera CCU set up with Chroma Du Monde chip charts.
