Tests must be performed at the same locations each time and are performed repeatedly in a 24-hour period in order to make comparisons between test periods. At each test point, electrical tests must be made on at least eight channels for a 450 MHz system or higher the size of Santa Ana's (Santa Ana is now a 750MHz system). Subjective picture quality observations were made on all channels at each test point. In July, 2007 the City cable consultant, Communications Support Group (CSG), VP participated in Time Warner's warmest month tests. Mr. Newell Whitfield, Consulting Engineer oversaw the latter part of these tests (less the 24-hour tests). Field tests were done in two consecutive days starting on July 26th , 2007 by Time Warner and were completed on July 27th, 2007. Actual measurements performed on both days were taken by representatives of Aldephia Cable and witnessed by Mr. Whitfield. Observations were made at the system Headend and at 5 locations through out the distribution system. This year is the second round of three years of testing newly chosen test points. A decision will be made to select five new test points that will continue to represent a full span of the city beginning in 2009. The same test points are typically chosen for performance consistency on an annual basis for 3 to 5 years. It was the request of the city to begin choosing alternating new test points every 3 years. The test locations chosen are located on end of lines and at geographical extremities of the cable system, which means, complete test point coverage that encompasses the entire city. A map is attached for a visual of the areas covered for this years test point locations. Participants in initial meetings with Mr. Whitfield on July 26th from Time Warner included Mr. Cliff Bridges, Technical Operations, Mr. Junior Lopez, Sweep Technician, and Jesse Foster, Headend Engineer.
