RFmx WLAN is application software that provides simple access to advanced optimization techniques such as multimeasurement parallelism and multi-DUT measurements. The result is fast, high-quality measurements that abstract the complexities of lower-level wireless standards and RF instrumentation. RFmx WLAN supports various OFDM physical layers in single transmit-chain configurations. It also supports making modulation accuracy, transmit power, and spectral emission mask measurements on OFDM and DSSS physical layer signals. RFmx WLAN is completely interoperable with all RFmx APIs.
