The R&SFSH4 and R&SFSH8 handheld spectrum analyzers from Rohde & Schwarz offer new functions for the installation and servicing of CDMA and Long-Term Evolution (LTE) mobile radio networks. In their basic configuration, these analyzers now can perform measurements in the spectral range. For example, they can detect spurious emissions and display the associated limit values. Thanks to their 20-MHz bandwidth, they also can be used to analyze LTE signals.

With two new software options, the R&SFSH-K46 and R&SFSH-K46E, they can analyze CDMA2000 signals as well. These options provide all the functions that service and installation technicians need to check the operationally relevant parameters of CDMA2000 basestation signals.

The R&SFSH-K46 option measures the power, determines the ratio of peak power to average power, and displays characteristic parameters such as the power in both the pilot channel (F-PICH) and the synchronization channel (F-SYNC), the carrier frequency offset, composite error vector magnitude (EVM), and rho.

The R&SFSH-K46E option has been designed for more in-depth analysis. It also can perform code domain power measurements, which provide the information needed for graphically displaying the powering all occupied and unoccupied channels, for example.

Additional new measurement functions have been incorporated into the base unit, including the ability to measure spurious emissions that might interfere with the adjacent transmit signal. Predefined masks for CDMA2000, WCDMA, TD-SCDMA, WiMAX, and LTE enable users to measure the spectrum emission mask quickly, with minimum operating effort. The gated sweep function makes it possible to display pulsed signals in the spectrum.

The R&SFSH4 and R&SFSH8 handheld spectrum analyzers from Rohde & Schwarz offer new functions for the installation and servicing of CDMA and LTE mobile radio networks.

Applications for LTE will soon become available, in addition to the applications for 1xEV-DO, 3GPP WCDMA, and CDMA2000.
