Aside from offering convenience, hand-portable spectrum analyzers are increasingly providing higher performance and an impressive feature set. The 9102 handheld spectrum analyzer, for example, can now operate at frequencies up to 7.5 GHz. The 9102 flaunts a minimum resolution bandwidth of 1 kHz. It has a dynamic range of 70 dB. The analyzer features a displayed average noise level (DANL) of –117 dBm. Among the instrument's many options, voltage-standing-wave-ratio (VSWR) and distance-to-fault (DTF) measurements support antenna installation and verification. In addition, the tracking-generator option enables cable measurements in the field. An electromagnetic-field (EMF) option performs radiation measurements of base stations and broadcast stations. The handheld spectrum analyzer also performs antenna measurements and scalar network analysis. For this analysis, it provides amplifier gain over frequency or filter characteristics. The applications covered by the 9102 handheld spectrum analyzer with the 7.5-GHz frequency extension include signals in the 5-GHz unlicensed band.
