R&S FSL18 spectrum analyzer
Featuring a frequency range of 9 kHz to 18 GHz, the R&S FSL18 can perform measurements on microwave systems. This includes 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 R&S FSL family, the new spectrum analyzer is the only instrument in its class to support the WLAN, WiMAX and WCDMA standards.
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 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 <1.2 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 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 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.
