The Rhode & Schwarz FSH4 and FSH8 are ideal for maintaining or installing transmitter systems, checking cables and antennas, and assessing transmitted signal quality.

The Rhode & Schwarz FSH4 and FSH8 facilitate complete and efficient field measurements. These rugged, lightweight, and portable spectrum analyzers are ideal for maintaining or installing transmitter systems, checking cables and antennas, and assessing transmitted signal quality (see the figure). They check signal quality in the frequency and time domains using channel power and pulsed signal measurements.

The analyzers can demodulate and analyze all signal bandwidths up to 20 MHz that are defined in the Long-Term Evolution (LTE) standards from single-input single-output (SISO) to 4x4 multiple-input multiple-output (MIMO) transmissions. They also can demodulate and analyze signals of the 3GPP WCDMA, CDMA2000, and 1xEV-DO standards as well.

Furthermore, they can measure the spurious emissions of a mobile radio basestation by 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 portable FSH family delivers spectrogram analysis of intermittent faults, distance-to-fault measurements on cables, and one-port cable loss measurements. The analyzers also measure antenna matching, test power amplifiers using full two-port vector network analysis, and provide for a number of RF power measurement modes.

These devices additionally can serve as highly accurate RF power meters up to 67 GHz when coupled with NRP power sensors from Rohde & Schwarz. Utilizing the FSH series power sensors, the FSH models can simultaneously measure the output power and matching transmitter system antennas under operating conditions up to 120 W and normally eliminate the need for any extra attenuators.
