ITEM DESCRIPTIONPICTURE IS ONE OF THE UNITS ON SALE ~ UNITS ARE IDENTICAL
* Four External VITS Inputs for Insertion of Teletext, Closed Captioning, Source ID, Etc.* Nonvolatile Memory to Maintain Selected VITS and Full Field Signal Configuration After Power Interruption* Signal Stored in Replaceable PROMs* The Accuracy and Stability of All-digital 10-Bit Sync and Signal Generation* RS-232 Remote Control Port
The 1910 Digital Generator is a state-of-the-art test signal generator designed for performance testing of NTSC video systems and equipment. The 1910 is especially suited where high accuracy and stability are required. It is also a VITS inserter (internal and external) with a full complement of signals that allow testing in studio, transmitter, production or research environments. Four external VITS inputs permit insertion of signals such as videotext, closed captioning, source ID, and other similar sources. These four inputs may be converted to four pulse outputs for use in a production environment.
Test signals are stored as 10-Bit digital words and converted to analog form by a 10-Bit precision DAC (with deglitching to reduce differential gain and differential phase) to ensure signal accuracy as well as long term stability and repeatability.
Since all signals are stored in replaceable EPROMs, changing needs and industry standards will not cause obsolescence.
Control and versatility of the 1910 are greatly enhanced by the use of its RS-232 control port. Most functions of the 1910 can be controlled, reconfigured and saved. This includes VITS and full field signal selection, matrix signal creation, and sequences.
