Digital Video Component Analyser VCA is designed to solve measurement problems in the digital studio, in operation and servicing as well as in the development of digital studio equipment. Combining the characteristics of a waveform monitor and an analyser and including all conventional display modes, the VCA is suitable for a great variety of measurements and so makes working with digital video signals easy. An optional remote control unit permits the VCA to be readily integrated into large measuring systems for comprehensive monitoring in the studio.
Main features
- To standards ITU-R601/656, SMPTE125M/259M, 8 bits, 10 bits, 625/525 lines
- Waveform display
- Numeric output of video data
- Analysis of data frame/contents
- Timing and level measurements
- Hardcopy of screen via external printer
- DTL analysis (optional)
- Remote control (optional)
Equipped with a digital-parallel and a digital-serial video input as well as SCOPE and MEASURE functions, VCA is capable of monitoring the digital video signal at all the transfer points of a digital TV studio. Measurement results are clearly displayed on a large-size monitor. Compared to the purely visual information obtained from an oscilloscope, VCA reads out precise measurement values. A graphic display facilitates evaluation of the results.
SCOPE functions
These functions allow waveforms and numerical values of the digital video signal to be analysed.
MEASURE functions
These functions are used for monitoring and measuring live signals and for measuring special test signals. In the SCOPE mode, too, two monitoring functions are active in the background for checking the sync frame. The results of measurements on live signals are shown on the ERROR RATE display or on a new type of HISTORY display.
