Testor AV

4k UHD 12G-SDI or 4x 3G-SDI Audio & Video Test Signal Generator. With AV Synch Analyzer functionality

Datasheet Quickreference


The greenMachine Testor is a multi-format video and audio test signal generator plus audio/video delay analyzer and measurement tool. This is the ideal solution for the verification, troubleshooting and alignment of AV systems either in the field as a portable device, or rack mounted with network control in a studio installation.

The greenMachine Testor has two primary modes of operation:
Single Channel 4k/UHD: Single link or quad-link (2SI) 12G-SDI
Quad Channel 3G: Four independent 3G-SDI channels

The green Machine Testor includes a library of industry standard test patterns which includes SDR static patterns, HDR static patterns, and dynamic (moving) patterns. All patterns can be customized with logos and text overlays if needed. You also have the ability to upload your own custom design test patterns.

The powerful AV delay analyzer and measurement tool allows for the precise measurement of the audio/video delay in 64 simultaneous channels of embedded audio in a 12G signal (or 16 channels in 3G). Simply feed the Testor pattern output into the signal path to be analyzed and then back into the Testor input. The results are shown graphically in LynxCentraal to visually identify early or late timing with a precise AV delay measurement of each audio channel.
