Thestrengths of this family of instrumentsare easy operation, sturdy housing, andlow weight. In addition, a built-in tracking generator and an integrated VSWRbridge enable you to perform DTF measurements on cables. You can use theseanalyzers to check antenna installationssuch as found at base stations and toanalyze the spectrum for interference.The instruments even display antennamatching in vector format in a Smithchart.The functionality of the R&S FSHmatches that of conventional lab instruments. Each instrument is equippedwith an RMS detector for precise powermeasurements, channel power measurements, and burst power measurements in the time domain, plus anAM/FM audio demodulator, versatilemarker functions and a port for connecting a power sensor. An increasingly important application is EMF analysis: The R&S FSH has been combinedwith an antenna and software to createa separate test system for this purpose –the new R&S TS-EMF [2].how from one instrument to the next.R&S FSH3 GHz/6 GHz handheld spectrum analyzer for mobile usein service and installationR&S FS300 Economical 3 GHz spectrum analyzer for universal applicationsin service and productionR&S FSPMedium-class spectrum analyzer up to 40 GHz for most laboratoryapplications, service and measurement tasks in productionSpectrum analyzer with highest dynamic range up to 50 GHz forR&S FSUlaboratory applications and for production when dynamic rangerequirements are highR&S FSQSignal analyzer with integrated spectrum analyzer up to 40 GHz(corresponding to the R&S FSU) and up to 120 MHz I/Q demodulation bandwidthFIG 1News from Rohde & Schwarz30Analyzers from Rohde & Schwarz.Number 182 (2004/II)

GENERAL PURPOSESpectrum analyzersFor all RF tasks – theR&S FS 300In addition, integrated complex measurement and analysis routines significantly speed up measurements. Thisincludes the List mode, which enablesyou to perform an entire series of measurements at various frequencies anddifferent settings by using a singleremotecontrol command. By using thisfunction together with many differentkinds of channel filters, the R&S FSPoperates like a very fast, accurate andselective power meter. You can alsouse the R&S FSP’s Fast ACP function tomeasure adjacent channel power withchannel filters in the time domain. Inaccordance with the selected standards,the analyzer tunes to different channelfrequencies one after the other, whereit measures the power in the predefinedmeasurement time using the channel filters specified for each frequency.Compared with conventional integration methods, performing measurements with the channel filters is approx.10 times faster. The VCO synthesizer concept makes frequency switching so fastthat total measurement time is hardlyaffected.The R&S FS300 is a compact, universaland economical spectrum analyzer withproperties previously found only in moreexpensive instruments [3]. The maximum permissible signal level is 33 dBm(2 W), which is more than most modernmobile phones are capable of, for example. This means low risk of destructionif power that is too high is unintentionally applied. For remotecontrol operation,this instrument relies on the widely usedUSB interface, eliminating the need foran IEC/IEEE bus card in the remote controller.Medium-class instrumentsredefined – the R&S FSPThe R&S FSP is far more that just theright analyzer for general applications inthe laboratory, in service and in the field.It is also the fastest RF spectrum analyzer currently available [4]. This makesit of particular interest for use in production and manufacturing. The followingbenchmarks show its enormous speedpotential.Both high measurement speed and intelligent analysis routines shorten testtimes and increase throughput, yieldinghighly effective production. Reliabilityis another major concern in production.Instruments must hold up well duringcontinuous operation. The optional electronic attenuator ensures high reliability. It can even cope with the largest ofswitching cycles without experiencingwear.Its sweep rate in manual operation –i.e. the number of possible sweeps persecond, including all processing timeand return time – is 100 sweeps/s inzero span. This is faster than is necessary even for adjustment purposes.This high speed is useful, for example, if averaging over a large number ofsweeps is necessary.The remaining functionality, which ison par with any high-end instrument,makes the R&S FSP the ideal analysistool in development if an extremely highdynamic range is not required, for example in the development of mobile phones.When it comes to application-specificfirmware, the R&S FSP is also comparable to the R&S FSU and R&S FSQ. Forexample, firmware is available for mea-A common benchmark in remotecontrol operation is the sweep rate whentransmitting all trace data via the IEC /IEEE bus. Capable of up to 80 sweeps/sin zero span and up to 55 sweeps/s forspans 10 MHz, the R&S FSP is probably today’s fastest analyzer.News from Rohde & Schwarz32Number 182 (2004/II)suring code domain power on 3GPP/WCDMA, cdma2000 or TD-SCDMA signals, for measuring the signal parameters of GSM or EDGE signals, and evenfor measuring EVM on WLAN signals inaccordance with IEEE802.11a.The analyzer is optimally suited for usein the field since its weight is very lowfor an instrument of its class. With theoptional battery power supply, it canalso be battery-operated.High-end for any requirement –the R&S FSUThe primary difference between the highend Spectrum Analyzer R&S FSU [5]and the R&S FSP is that the R&S FSUoffers an expanded dynamic range andRF performance, right up to the limit ofwhat is feasible. This is evident in itsphase noise, intermodulation propertiesand 1 dB compression point. In the frequency range around 1 GHz and up to2 GHz, which is important in mobile communications, it reaches a TOI of typically 25 dBm to 27 dBm. These values arewell in line with many high-end communications receivers. With a 1 dB compression point of 13 dBm, it can measure signals with a power of up to 5 dBm at an RF attenuation setting of0 dB, i.e. without impairment of the displayed average noise level. This factorand the instrument’s excellent phasenoise of –160 dBc (1 Hz) at 10 MHz fromthe carrier allow the R&S FSU to measure spurious emissions even on GSMor WCDMA base stations with minimumuse of filters. There is no need for expensive, tunable notch filters.Another example of the advantages ofits high dynamic range is its capability to measure adjacent channel poweron a 3GPP WCDMA signal. Its value of77 dB for a four-carrier signal is sufficiently different from the values commonly encountered in base stations and
