Rohde & Schwarz WLAN IEEE 802.11 True MIMO Tx measurement (software license)
The R&S®FS-K91 WLAN IEEE 802.11 True MIMO Tx measurement software license (part number 1211.1447.02) enables comprehensive transmitter measurements for IEEE 802.11a/b/g/n/ac/ax (Wi-Fi 4/5/6) signals with true MIMO capability on supported Rohde & Schwarz signal and spectrum analyzers. This option provides advanced analysis features such as EVM, constellation diagram, spectrum mask, and spectral flatness for up to 8x8 MIMO signals. It supports both single and multi-user MIMO, allowing detailed insight into the performance of each spatial stream. The software is designed for R&S®FSV, R&S®FSVA, R&S®FSW, and compatible analyzers, facilitating compliance, development, and troubleshooting tasks for WLAN devices. The license is delivered electronically and requires a base instrument with the appropriate firmware version.
