The portable R&S FSL18 spectrum analyser from Rohde & Schwarz meets the growing need for compact instruments in applications such WiMAX network installation and maintenance.

Weighing in at less than 8kg, the FSL18 delivers a unique combination of wide frequency range (9kHz to 18GHz) and large I/Q demodulation bandwidth (28MHz)—particularly for an entry-level instrument.

With a frequency range of 9kHz to 18GHz, the R&S FSL18 handles radar and microwave link systems as well as production tests on microwave components such as mixers and amplifiers.

Its large I/Q demodulation bandwidth plus the software capabilities of the R&S FSL family make it only instrument in its class to support the WLAN, WiMAX and W-CDMA standards.

Transmitter measurements for civil and military applications—from WiMAX and Satcom up to radar—can be performed easily. When equipped with the R&S FSL-K9 option, the R&S FSL supports the direct connection of power sensors from the R&S NRP family. This increases the accuracy of the measurements and eliminates the need for an extra power meter.

An overall measurement uncertainty of <1.2dB at 18GHz ensures precise results, even in the microwave range. In addition, the instrument's resolution bandwidths (RBW) from 1Hz to 10 MHz (20 MHz at zero span) provide high flexibility for analysing pulse signals in both the frequency and time domains.

For production applications, the R&S FSL18 is a cost-efficient solution with a wide range of functions. Its measurement speed of 80 sweeps/s in the zero span (including all data transfers) ensures high throughput.

The frequency list mode allows engineers and technicians to perform measurements with up to 300 analyser settings using a single remote-control command.

The instrument also features power measurements with channel filters in the time domain and a fast frequency counter with a resolution of 0.1Hz at a measurement time of less than 50ms.

The R&S FSL18 is now available from Rohde & Schwarz.
