Tests must be performed at the same locations each time and are performed <br />repeatedly in a 24-hour period in order to make comparisons between test <br />periods. At each test point, electrical tests must be made on at least eight <br />channels for a 450 MHz system or higher the size of Santa Ana's (Santa Ana is <br />now a 750MHz system). Subjective picture quality observations were made on <br />all channels at each test point. <br />In July, 2008 the City cable consultant, Communications Support Group (CSG), <br />VP participated in Time Warner's warmest month tests. Mr. Newell Whitfield, <br />Consulting Engineer oversaw the latter part of these tests (less the 24-hour <br />tests). Field tests were done in two consecutive days starting on July 24th , 2008 <br />by Time Warner and were completed on July 25th, 2008. Actual measurements <br />performed on both days were taken by representatives of Time Warner and <br />witnessed by Mr. Whitfield. Observations were made at the system Headend <br />and at 5 locations through out the distribution system. <br />This year is the third round of three years of testing newly chosen test points. A <br />decision will be made to select five new test points that will continue to represent <br />a full span of the city beginning in 2009. The same test points are typically <br />chosen for performance consistency on an annual basis for 3 to 5 years. It was <br />the request of the city to begin choosing alternating new test points every 3 <br />years. The test locations chosen are located on end of lines and at geographical <br />extremities of the cable system, which means, complete test point coverage that <br />encompasses the entire city. A map is attached for a visual of the areas covered <br />for this years test point locations. <br />Participants in initial meetings with Mr. Whitfield on July 24, 2008 from Time <br />Warner included Mr. James Jakel, Technical Operations, Mr. Carlos Contreras <br />and Jesse Rodriguez, Maintenance 11 Technicians, and Brian Lesnik and Mark <br />Mercado, Headend Engineers. <br />2.
