The R&S FSH18, with a frequency range of 10 MHz to 18 GHz, is perfect for field applications including testing of microwave signals, field strength measurements and signal monitoring.  FSH18 comes in the same size and weight as the R&S FSH3 and R&S FSH6 handheld spectrum analyzers. 

The R&S FSH18 can characterize signals of radar stations, air traffic control systems, satellite systems, and microwave links – and simultaneously detect interfering signals. With its long battery operating time of up to three hours and robust design, it is especially valuable for outdoor use. Since it only weighs 2.5 kg, it can be easily carried over longer distances and also on difficult terrain. The R&S FSH18 can also be used in the lab for general measurement tasks up to 18 GHz. Moreover, the R&S FSH models are the only handheld spectrum analyzers worldwide that are able to perform high-precision terminating power measurements as well as directional power measurements by means of external power sensors, thus eliminating the need for an additional power meter during field applications.

Like the R&S FSH3 and R&S FSH6 models, the R&S FSH18 excels with high measurement accuracy of up to 1.5 dB. In addition to a resolution bandwidth of 100 Hz to 1 MHz, the R&S FSH18 features an inherent noise of typically –148 dBm at a bandwidth of 1 Hz in the range between 3 GHz and 6 GHz. Its simple menu-based operation and predefined measurement functions such as for channel power, electric field strength, and carrier/noise ratio (C/N) make it easy to use.
