Producers & Engineers -The Datavideo VS-150 is a table top or rack-mounted instrument that displays HD/SD-SDI vectorscope, waveform, parade, and histogram information at the push of a button. You'll always know whether your color and luminance levels are consistent and within spec. The scope data can be easily displayed on a large separate HDMI or HD/SD-SDI monitor or in the HD/SD-SDI video stream.
