With scalar transmission option, scalar measurements can be made between 1-port ShockLine™ MS46121A VNAs in either one-to-one or one-to-many configuration, offering solution for testing cable and filter transmission properties in manufacturing and education environments. In one-to-one setup, up to 2 scalar transmission measurements can be made in parallel using 4 channels. One-to-many configuration allows one MS46121A to serve as source that is connected to up to 3 VNAs that act as receivers.
