Rohde & Schwarz FSL18 Spectrum Analyzer

Manufacturer: Rohde & Schwarz
Model Number: FSL18
The R&S FSL is a lightweight and compact spectrum analyzer that is ideal for a large number of applications in development, production and service. Despite its compact size, it offers functions typical of high-end spectrum analyzers, with an excellent price/performance ratio. The R&S FSL is the only instrument in its class that features a tracking generator up to 6 GHz and can demodulate I/Q signals with a bandwidth of up to 28 MHz. In addition, this instrument has excellent documentation and networking capabilities with a Windows Embedded operating system, a standard LAN interface as well as a standard USB host interface.
