Rapid, high-precision, cost-effective signal investigations from 100 kHz to 3 GHz The R&S FSH3 is the ideal spectrum analyzer for rapid, high-precision, cost-effective signal investigations. It provides a large number of measurement functions and so can handle anything from the installation or maintenance of a mobile radio base station, through on-site fault location in RF cables to development and service - an extensive range of applications.

A large number of measurement functions enable the R&S FSH3 to handle anything from installation or maintenance of mobile radio base stations, through on-site fault location in RF cables to simple lab applications. Function keys and a simple menu structure make the R&S FSH3 easy to use. It offers the best RF characteristics and high measurement accuracy in this class of spectrum analyzers. The handheld spectrum analyzer R&S FSH3 also features 4 hours of continuous operation on battery power, rapid and easy data transfer to PC and an excellent price/performance ratio.

One application, the channel-power measurement function is for determining the power in a transmission channel specified by the user. After a few preliminary settings have been made, a single keystroke starts the R&S FSH3 's spectrum measurement inside the channel, using a resolution bandwidth that is small relative to the channel bandwidth.

The R&S FSH3 then integrates the measured values indicated by the trace to obtain and display the total power. All the settings required for the digital mobile radio standards 3GPP WCDMA, cdmaOne, CDMA2000 1x are predefined ready for use.

When the accessory Power Sensor R&S FSH-Z1 or R&S FSH-Z18 is fitted, the R&S FSH3 is transformed into a high-precision RF power meter with a maximum frequency of 8 GHz or 18 GHz. As with thermal sensors, the true RMS value of the measured signal is obtained over the whole measurement range irrespective of the signal waveform.
