摘要:
Various aspects of the R3681, a test tool for analyzing spectrum and broadband modulation, are discussed. The R3681 features an average noise level of -156 dBm/Hz, 26-dBm typical third-order intermodulation distortion and a 142-dBm dynamic range. It is found that optional wireless local area network (WLAN) software allows the R3681 to perform orthogonal frequency division multiplexing (OFDM) analysis.
