Handheld Spectrum Analyzers Ease Remote Basestation Maintenance

For maintaining or installing transmitter systems, checking cables and antennas, and assessing transmitted signal quality, the FSH4 and FSH8 Series lightweight and portable spectrum analyzer can also demodulate and analyze all signal bandwidths up to 20 MHz that are defined in the LTE standard.  Coupled with demodulation and analysis of 3GPP WCDMA, CDMA2000, and 1xEV-DO, the FSH provides a complete solution for today’s field maintenance needs. The FSH4/8 checks signal quality in the spectral and time domain using channel power and pulsed signal measurements. It measures spurious emissions of a mobile radio base station using the spectrum emission mask (SEM) function. In addition, the FSH family delivers spectrogram analysis of intermittent faults, distance-to-fault measurements on cables, and one-port cable loss measurements. ROHDE & SCHWARZ INC., Columbia, MD.
