Test description Measure the insertion losses from the SCLPA output to the duplexer antenna port. The test setup is shown in Figure 12 . Test Limitations Test Results and Concilusions System 1: The transmit path insertion loss for alt 8 channel siots of each of shelves 1 and 2 met the above specification across the 0.3 to 2000 MHz bandwidth. Between 824 MHz and 849 MHz, the insertion loss is larger than —96.2 dB. The responses for all 8 slots of both shelves 1 and 2 are very similar to Figure 14. System 2: The transmit path insertion loss for all 8 channel siots of each of shelves 1 and 2 met the above specification across the 0.3 to 2000 MHz bandwidth. Between 824 MHz and 849 MHz, the insertion loss is larger than —95.9 dB., The responses for all 8 siots of both sheives 1 and 2 are very similar to Figure 14. System 3: The transmit path insertion loss for all 8 channel siots of each of shelves 1 and 2 met the above specification across the 0.3 to 2000 MHz bandwidth, as shown in Figure 14. Between 824 MHz and 849 MHz, the insertion loss is larger than —96.9 dB. The dotted line in Figure 14 shows the frequency masks for the specs and Appendix D. Other systems: Please see "Appendix D" for more results in 3 Email reports. Page 32 June 7,1996— —Issue 1.0— — Release AUG 11 1999 15:05 403 232 4051 PACGE .06
