The portable R&S FSL18 from Rohde & Schwarz expands the company's product portfolio for spectrum analysis to meet the increasing demand for compact instruments in applications such as the installation and maintenance of WiMAX networks. For the entry-level class, its combination of wide frequency range and large I/Q demodulation bandwidth (28 MHz) is unique, according to R&S.

Featuring a frequency range of 9 kHz to 18 GHz, the FSL18 can perform measurements on a variety of microwave systems, including Radar and microwave link systems as well as production tests on microwave components such as mixers and amplifiers. Due to its large I/Q demodulation bandwidth and the extensive software capabilities, the new spectrum analyzer is the only instrument in its class to support the WLAN, WiMAX and WCDMA standards, claims the manufacturer.

The instrument's low weight (<8 kg) and DC/battery operation also make it ideal for mobile use in the field when no AC supply is available. Transmitter measurements for civil and military applications – from WiMAX and Satcom up to Radar – can be performed easily. When equipped with the FSL-K9 option, the FSL supports the direct connection of power sensors from the NRP family. This increases the accuracy of the measurements and eliminates the need for an extra power meter, explained the supplier.

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

For production applications, the 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, stated R&S. The frequency list mode allows engineers and technicians to perform measurements with up to 300 analyzer settings using a single remote-control command. Moreover, the spectrum analyzer features power measurements with channel filters in the time domain and a fast frequency counter with a resolution of 0.1 Hz at a measurement time of less than 50 ms.

The FSL18 is now available, said R&S.
