Specifications
This section contains tables that list the specifications for the VITS100 NTSC
VITS Inserter. All specifications are guaranteed unless noted “typical.”
The performance limits in this specification are valid with these conditions:
HThe VITS inserter must have been calibrated/adjusted at an ambient
temperature between +20_ C and +30_ C.
HThe VITS inserter must be in an environment with temperature, altitude,
humidity, and vibration within the operating limits described in these
specifications.
HThe VITS inserter must have had a warm-up period of at least 20 minutes.
