Product Specification

4.6. Test method :

4.6.1.Insertion loss at 1004Hz :

4.6.1.1. Description :

CPF120A

For each of the test loops specified in 4.3, and using the test set-up shown in Figure

2 .the insertion loss from the source to the termination shall be measured with and

without the splitter / ZHP combination inserted.The increase in insertion loss at

1004Hz on any of the test loops , due to the addition of the splitter / ZHP , shall be less

than specified in Table 1.
