The Rohde and Schwarz FSL-K91 is a software option for WLAN transmitter measurement for IEEE 802.11a, b, g, j.

The excellent price/performance ratio, the compact size, and the capability to be remote-controlled make the R&S FSL an ideal WLAN tester in production. The R&S FSL's analysis and evaluation capabilities, which enable measurements beyond the scope of the standard, make it indispensable for applications in development and troubleshooting. Functions, operation, and remote control commands are essentially identical to those of the R&S FSQ signal and spectrum analyzer with the R&S FSQ-K91/-K91n option.
