R&S Develops Handheld Spectrum Analyzer for Field Maintenance of Base Stations
Rohde & Schwarz, a leading manufacturer of test & measurement, communications and broadcasting equipment, has developed a rugged, lightweight and portable spectrum analyzer that provides complete and efficient field measurements. Ideal for maintaining or installing transmitter systems, checking cables and antennas, and assessing transmitted signal quality, the FSH4 and FSH8 Series 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 W-CDMA, CDMA2000, and 1xEV-DO, the FSH provides a complete “All-In-One” solution for today’s field maintenance needs.
The R&S FSH4/8 portable spectrum analyzer checks signal quality in the spectral and time domain using channel power and pulsed signal measurements. The spectrum analyzer measures spurious emissions of a mobile radio base station using the spectrum emission mask (SEM) function. Spurious emissions can interfere with adjacent transmit signals, resulting in reduced signal quality and lower data rates.
“The FSH Series provides the most important analysis functions that an RF service technician or an installation and maintenance team needs to solve daily routine RF measurement tasks,” said Rich Pieciak, Product Manager at Rohde & Schwarz. “Further, the FSH family supports all important LTE measurements, from single input, single output (SISO) to 4x4 multiple input, multiple output (MIMO) transmissions.”
In addition, the portable FSH family delivers spectrogram analysis of intermittent faults, distance-to-fault measurements on cables and one-port cable loss measurements. The FSH Series spectrum analyzer also measures antenna matching, tests power amplifiers using full two-port vector network analysis, and provides for a number of RF power measurement modes. The FSH Series can also serve as a highly accurate RF power meter up to 67 GHz when coupled with NRP power sensors from Rohde & Schwarz. Utilizing the FSH Series power sensors, the FSH models are also capable of simultaneously measuring the output power and matching transmitter system antennas under operating conditions up to 120 W and normally eliminate the need for any extra attenuators.
