N9330A is a handheld, easy to use, battery operated cable and antenna tester for field installation and maintenance. It measures return loss, SWR, cable loss and distance-to-fault test functions for wireless service providers (WSPs), Aerospace & Defense customers, TV & Broadcasting customers and contractors for these markets.

The electronic calibrator automatically enables three-status (open, short and load) calibration for the N9330A with one connection. Compared to a mechanical calibrator, the electronic calibrator improves field calibration efficiency by a factor of two to three.
