Insertion Loss Measurement Methods

From Anritsu Company
 

 
Transmission feed line system performance plays an important role in wireless network coverage. Insertion loss measurement is one of the critical measurements used to analyze transmission feed line installation and performance quality. This application note explains how Site Master is used to measure cable insertion loss with different test methods and how to predict the maximum allowable cable insertion loss through manual calculations. In wireless communication systems, the transmit and receive antennas are connected to the radio through coaxial cable and/or waveguide transmission lines (Figure 1). Insertion loss measures the energy absorbed by the transmission line in the direction of the signal path in dB/meter or dB/feet. Transmission line losses are dependent on cable type, operating frequency and the length of the cable run. Insertion loss of a cable varies with frequency; the higher the frequency, the greater the loss.
