Signal and spectrum analyzer analyzes IEEE 802.11ac WLAN signals

ROHDE-SCHWARZ FSW-K91ac option provides an integrated demodulation bandwidth of 160 MHz, enabling the R&S FSW signal and spectrum analyzer to record and demodulate the full bandwidth of a WLAN signal in line with IEEE 802.11ac. The error vector magnitude (EVM) is an important measure of the modulation quality. The IEEE 802.11ac standard requires an EVM of –32 dB for 256QAM modulation. To accurately measure this parameter, the T&M equipment itself must have a very low EVM, such as the R&S FSW with an EVM of less than –45 dB.
