The DSC Labs Combi DX-1 Test Target (ColorBar / GrayScale) is a rear-lit test chart designed for calibrating the color and resolution on your video camera. It features 6 primary vector colors, 11-step crossed grayscale, Center 700 mV (100 IRE) white chip and 2 true black chips. In addition, it also includes hyperbolic resolution wedges up to 1200 TV LPPH (15 MHz) and calibration data.
You can use the Combi DX-1 Test Target as a precision optical signal generator that produces waveform and vectorscope displays similar to standard electronic test signals. In addition, it can be used to align multiple cameras using the chart's color patches. The chart can be used for aligning different types of lighting such as quartz, HMI and fluorescent. It also features a maximum tolerance level of 5 CIE LxUxV units and an RMS maximum of 2 units.
