The DSC Labs Combi DX-1 Test Target (ColorBar / GrayScale + 4) is a rear-lit test chart designed for calibrating the color and resolution on your video camera. It features 6 primary vector colors + 4 skin tone patches, 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. The chart can be used to align multiple cameras using the color patches, and for aligning different types of lighting such as quartz, HMI, and fluorescent.
The Combi DX-1 Test Target features a maximum tolerance level of 5 CIE L*U*V units and an RMS maximum of 2 units. Designed for use with Ambi illuminator, the chart can also be used with other light boxes or spherical illuminators.
