VIT-700 Series VITS Inserters Low cost Vertical Interval Test Signal (VITS) inserter for either NTSC and 525 Y/C video formats, or PAL and 625 Y/C Video Formats
VITS Signals include FCC, NTC7, CCIR and UK National Interval Test Signals. Also features the Philips Ghost Cancelling Reference Signal.
The VIT-700G Vertical Interval Test Signal Inserter gives you the cost-effective capability to insert reference signals in all phases of video production and routing. The VIT-700G provides NTSC insertion test signals for evaluating video quality in operational applications. VITS sets include FCC, NTC7 and the Philips Ghost Cancelling Reference (GCR) signal for both transmission and routing. The VIT-701 ITS inserter provides the PAL Insertion Test Signals. The VIT-700G/VIT-701 Inserters allow full utilization of the Magni WVM Series' automated measurement and monitoring capabilities during video production and routing or for on line testing.
