Latest EMC measurement software “EPX/RE” leading the Accelerated Time Domain Scan feature a success The “EPX/RE”, completely new radiated emission measurement and evaluation software enables highly reliable EMI measurement without missing any noise, which is achieved by embedding in its auto measurement sequence the Accelerated Time Domain Scan feature, an optional feature for Keysight Technologies’ N9048B PXE EMI receiver. The measured noise data are also quite effective for taking countermeasures against noise as you can analyze the behavior of noise in relation to frequency but also in time sequence.
