Performing cable loss (1 port) measurements 

The Cable Loss (1 Port) measurement quantifies signal loss through a cable or other device over a 
defined frequency range by range by connecting one end of the cable to the instrument measurement 
port and terminating the other end of the cable with a short, or leaving it open altogether. This
