Sweep testing verifies system integration and antenna performance. It can also test the characteristics of a device across a range of frequencies. This convenient test demonstrates if an installation meets the required performance specifications.
Sweep testing is completed with two standard tests – return loss and insertion loss. Return loss measures the power transfer efficiency of the antenna at the cell site. The power that is returned needs to be lower, otherwise, the transmitter can be damaged. The insertion loss measures the amount of signal loss through a coaxial system. Line sweeping measures the signal losses and reflections of the transmission system and is important to be performed before PIM testing. It is important to perform a line sweep test before PIM testing to ensure the insertion loss and return loss data are at acceptable levels. This, in turn, assures that the PIM test signals actually reach the components at the highest possible signal level, offering a more accurate indicator of PIM performance.
Avalon Test Equipment carries a variety of sweep gear available to rent or purchase.
Avalon has Anritsu site masters in stock and ready to ship. We also offer Sweep Fundamentals Training that will prepare your crews for testing so you can Test With Confidence®.
