R&S®FSMR Measuring Receiver All-in-one calibration of signal generators and attenuators Product Brochure | Version 04.00

R&S®FSMR Measuring Receiver At a glance The R&S®FSMR measuring receiver has been specially designed to handle the measurement tasks involved in the calibration of signal generators and fixed or adjustable attenuators. The R&S®FSMR combines the functionality of several instruments in one and is capable of calibrating all vital parameters of a signal generator. The R&S®FSMR offers full spectrum analyzer functionality, e.g. for measuring harmonics or phase noise. The base unit does not provide for image frequency rejection in the range above 3.6 GHz since the YIG filters normally used for this...

Level calibration – precise, ­repeatable and easy Excellent linearity and level stability The linearity of the R&S®FSMR is almost exclusively determined by its high-quality A/D converter and the limits of traceability of calibration. Modules and components on which drift (YIG filter) or nonlinear level response (­ rystal c filter) may occur are switched off during level ­ alibration. c As a result, the R&S®FSMR features linearity values equal to or even better than those of the present industry standard. After warmup, the R&S®FSMR offers excellent level stability. This allows measure­ ents...

Easy operation for level calibration over a wide level range To perform measurements over the full level range of conventional RF ­ enerators, e.g. from –130 dBm to +10 dBm, g it is necessary to switch the built-in RF attenuator of the R&S®FSMR or the IF gain as required. The R&S®FSMR eliminates any level errors that may ­ ccur as a result of o range switching by calibrating the adjacent range ­ rior to p switchover. As a result, the user can benefit from the in­ strument‘s high linearity of 0.01 dB + 0.005 dB deviation per 10 dB across the entire level range. Level calibration is carried...

Direct connection of power sensors for accurate power measurements Power sensor module with integrated power splitter The absolute power and the reference power are measured with high accuracy by a power meter. The power meter can be connected to the generator output or operated in parallel with the analyzer input via a power splitter. The R&S®FSMR automatically corrects the power splitter's frequency response and insertion loss based on an internally stored correction table. Control of all functions incl. power meter from front panel or via IEC/IEEE bus or LAN The R&S®FSMR controls the...

Modulation and a ­ udio analysis made easy The R&S®FSMR features a complete, integrated modulation and audio analyzer for the AM, FM and φM analog modulation modes. Audio parameters are measured either on the ­ emodulated signal or on the signal applied to the d audio input. This means that no extra instrument is required for calibrating modulation settings and the modulation generator. Various audio filters, deemphasis functions and detectors are ­ vailable for audio analysis. This makes it easy to pera form residual FM measurements, for example. The R&S®FSMR not only displays the...

Versatile, ­highperformance ­spectrum analysis Full-featured spectrum analyzer Calibration labs handle a variety of measurement tasks. These tasks often require a spectrum analyzer featuring a wide range of functions and excellent allround performance. The R&S®FSMR includes as standard a spectrum a ­ nalyzer that meets these requirements and, with the YIG filter option fitted, provides image frequency rejection up into the microwave range. The built-in spectrum analyzer of the R&S®FSMR offers functionality and performance equivalent to that of the R&S®FSU spectrum analyzer. Full choice of...

The R&S®FSMR-Z2 attenuation calibration kit is used to calibrate the level ­inearity of the R&S®FSMR as described l in the R&S®FSMR performance test (included in the manual). The attenuation calibration kit enables calibration laboratories to recalibrate the level linearity of the R&S®FSMR by themselves. The kit is PTB-calibrated and consists of the following: ❙❙ 3 × 6 dB attenuators ❙❙ 2 × 10 dB attenuators ❙❙ 2 × 20 dB attenuators ❙❙ PTB calibration certificate Attenuation calibration kit with case. Attenuation calibration kit for verifying the R&S®FSMR linearity. Rohde & Schwarz R&S®FSMR...
