Inter-System Multi-Order PIM Testing System

basic information
Product description
Inter-System Multi-Order PIM Testing System

Nowadays the network environment is more and more complicated, there’re various standards of the signals co-exist in the network optimization system, the consequence is inter-system PIM interference. 

The inter-system multi-order PIM testing system is to realize the inter-system PIM testing of passive components; it gives an effective method to evaluate the inter-system PIM performance of passive components, to
ensure and improve network connection of the indoor wireless distribution system.


Product Features
