AI summary
A testing device is provided that evaluates the operating performance of radio frequency (RF) emitting devices such as a counter-unmanned aircraft system (C-UAS) device. The testing device allows an operator, with limited RF knowledge, to conduct testing on a C-UAS device and quickly verify functionality in any location with no data analysis. The testing device provides a simplified and portable method to test the RF output of devices such as C-UAS. Since C-UAS devices use RF power to disrupt their UAS target, the performance can be assessed by verifying the RF power level emitted by the C-UAS device. In order to do this the testing device measures and assesses the RF power levels in the bands that the C-UAS device emits radio frequency energy.
