Abstract In response to the issues of the main standard devices being discontinued and the cumbersome calibration process in the calibration of video analyzers, based on virtual instrument technology and in the LabVIEW development environment, a video analyzer calibration device was developed using the M4i.6622-x8 arbitrary waveform generation card as the signal generation module.The basic parameters and distortion parameters of the video analyzer were calibrated.The calibration signal generation process for Lum level, Chrom level, Chrom phase video basic parameters and Tilt, 2T Pulse k-factor, C/L Gain and Delay, Lum NL video distortion parameters were provided.By experiment, the technical indicators can achieve: Lum level is ±0.2%, Chrom level is ±0.2%, Chrom phase is ±0.1°, Tilt is ±0.1%, 2T Pulse k-factor is±0.1%, C/L Gain is ±0.2%, C/L Delay is ±3ns, Lum NL is ±0.2%.The technical indicators are better than the TG2000 programmable video signal generator, meeting the calibration requirements of video analyzers.
