For EMC immunity testing, output VSWR is generally not a critical parameter, provided it remains within reasonable limits. In practice, EMC test levels are calibrated using the forward power, making the power meter more important than the generator’s output VSWR. Also more important than output VSWR are RF performance characteristics such as fast rise time and monotone RF signal generation. The RadiGen series RF signal generators deliver outstanding performance, with rise times up to 10× faster than conventional signal generators and pure, glitch-free RF carrier generation. These features enable faster, more accurate, and more reliable EMC immunity testing.
