Microwave spectrum analyser

The portable microwave spectrum analyser, 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 claimed to be unique.

Featuring a frequency range of 9 kHz to 18 GHz, the instrument can perform measurements on microwave systems that include 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 of the family, the analyser is said to be the only instrument in its class to support the WLAN, WiMAX and WCDMA standards.

The low weight of \<8 kg and battery operation also make it suitable for mobile use. Transmitter measurements for civil and military applications — from WiMAX and Satcom up to radar — can be performed easily.

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 analysing pulse signals in both the frequency and time domains. For production applications, the FSL18 is a 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.
