Page 32: Measuring Signals In The Vicinity Of Noise
R&S FSP Getting Started Measuring Signals in the Vicinity of Noise If the intermodulation products of a DUT with a very high dynamic range are to be measured and the resolution bandwidth to be used is therefore very small, it is best to measure the levels of the useful signals and those of the intermodulation products separately using a small span.

Page 34 R&S FSP Getting Started Measuring Signals in the Vicinity of Noise Impact of the video bandwidth The displayed noise of a Spectrum Analyzer is also influenced by the selected video bandwidth. If the video bandwidth is considerably smaller than the resolution band- width, noise spikes are suppressed, i.e.
Page 35: 1Measurement Example - Measuring The Level Of The Internal Reference Generator At Low S/N Ratios
R&S FSP Getting Started Measuring Signals in the Vicinity of Noise RMS detector For each pixel of the trace, the RMS detector outputs the RMS value of the IF enve- lope for the frequency range assigned to each test point. It therefore measures noise power.
Page 36 R&S FSP Getting Started Measuring Signals in the Vicinity of Noise Press the RF ATTEN MANUAL softkey and enter 60 dB. The RF attenuation indicator is marked with an asterisk (*Att 60 dB) to show that it is no longer coupled to the reference level. The high input attenuation reduces the reference signal which can no longer be detected in noise.

Page 38: Noise Measurements
R&S FSP Getting Started Noise Measurements 2.4 Noise Measurements Noise measurements play an important role in spectrum analysis. Noise e.g. affects the sensitivity of radio communication systems and their components. Noise power is specified either as the total power in the transmission channel or as the power referred to a bandwidth of 1 Hz.
Page 39 R&S FSP Getting Started Noise Measurements Conversion to other reference bandwidths The result of the noise measurement can be referred to other bandwidths by simple conversion. This is done by adding 10 · log (BW) to the measurement result, BW being the new reference bandwidth.
Page 40 R&S FSP Getting Started Noise Measurements Determining the noise figure: The noise figure of amplifiers or of the R&S FSP alone can be obtained from the noise power display. Based on the known thermal noise power of a 50 Ω resistor at room temperature (-174 dBm (1Hz)) and the measured noise power P the noise noise...

R&S FSP Getting Started Measurements on Modulated Signals 2.5.3.3 Measurement Example 3 – Measuring the Modulation Spectrum in Burst Mode with the Gated Sweep Function Since transmission systems compliant to IS136 use a TDMA method, the adjacent channel power must also be measured in burst mode. An IS136 TDMA frame is divided into 6 time slots.

Page 67 R&S FSP Getting Started Measurements on Modulated Signals Optimum Level Setting for ACP Measurements on W-CDMA Signals The dynamic range for ACPR measurements is limited by the thermal noise floor, the phase noise and the intermodulation (spectral regrowth) of the R&S FSP. The power values produced by the R&S FSP due to these factors accumulate linearly.
Page 68: Amplitude Distribution Measurements
R&S FSP Getting Started Measurements on Modulated Signals To measure the R&S FSP’s intrinsic dynamic range for W-CDMA adjacent chan- nel power measurements, a filter which suppresses the adjacent channel power is required at the output of the transmitter. A SAW filter with a bandwidth of 4 MHz, for example, can be used.
Page 69 R&S FSP Getting Started Measurements on Modulated Signals Set the APD softkey to ON. The R&S FSP sets the frequency span to 0 Hz and measures the amplitude probability distribution (APD). The number of uncorrelated level measurements used for the measurement is 100000. The mean power and the peak power are displayed in dBm.
Page 70 R&S FSP Getting Started Measurements on Modulated Signals 4. Bandwidth selection If the amplitude distribution is measured, the resolution bandwidth must be set in a way that the complete spectrum of the signal to be measured falls within the bandwidth. This is the only way of ensuring that all the amplitudes will pass through the IF filter without being distorted.

R&S FSP saves for each sweep the smallest of the previously stored/currently measured values in the trace memory.
Page 114 R&S FSP Instrument Functions Analyzer Mode This low average value is usually corrected in noise power measurements by a 2.5 dB factor. Therefore the R&S FSP offers the selection of linear averaging. The trace data are delogarithmized prior to averaging, then averaged and logarithmized again for display on the screen.

Page 175 R&S FSP Instrument Functions Analyzer Mode Measurement of Occupied Bandwidth An important characteristics of a modulated signal is its occupied bandwidth. In a radio communications system for instance the occupied bandwidth must be limited to enable distortion-free transmission in adjacent channels. The occupied bandwidth is defined as the bandwidth containing a defined percentage of the total transmitted power.
Page 176 R&S FSP Instrument Functions Analyzer Mode ADJUST REF The ADJUST REF LVL softkey adjusts the reference level of the R&S FSP to the measured total power of the signal. The softkey is activated after the first sweep with the measurement of the occupied bandwidth has been completed and the total power of the signal is thus known.
Page 177 R&S FSP Instrument Functions Analyzer Mode Some of the measurement specifications (e.g. PDC, RCR STD-27B) require mea- surement of the occupied bandwidth using a peak detector. The detector setting of the R&S FSP has to be changed accordingly then.

R&S FSP Instrument Functions Analyzer Mode TOI MKR CALC The TOI measurement is based on positioning the markers 3 and 4 onto the position SRCH of the calculated intermodulation products. The accuracy of these frequency calcula- tions depend on the precision of the two carrier frequencies found with peak search. The softkey TOI MKR CALC SRCH allows to switch between the calculated marker position (CALC) and perfoming a local peak search near the expected frequencies (SRCH) instead of the faster position calculation.

Page 194: 9Measuring Spurious Emissions
R&S FSP Instrument Functions Analyzer Mode 4.5.13.9 Measuring Spurious Emissions All real amplifiers also generate unwanted RF products outside the assigned fre- quency band. These spurious emissions are usually measured across a wide fre- quency range, for example from 9 kHz to 7 GHz. The analyzer settings are specified for each frequency range.
Page 195 R&S FSP Instrument Functions Analyzer Mode The frequency range where measurements are actually performed is set by the start and stop frequency parameters of the R&S FSP; these parameters are independent of the sweep ranges. It is thus possible to define sweep ranges for a measurement task that can be stored and reloaded and to quickly and easily set the frequency range to be actually measured by means of two parameters;...

Input signals in the wanted sideband that are converted by means of the set harmonic are displayed in both traces at the same position on the frequency axis.
Page 351 R&S FSP Instrument Functions LO/IF ports for external mixers - Option R&S FSP-B21 Tolerance for the comparison of test sweep and reference Since the LO frequency is displaced downwards in the reference sweep, the conver- sion loss of the mixer may differ from that of the test sweep. The reasons for this are the LO output power of the R&S FSP varying with the frequency and the non-ideal characteristics of the mixer.

Queries cause data to be provided for output on the GPIB, e.g. for identification of the device or polling the marker.
Page 372 R&S FSP Remote Control – Basics Structure and Syntax of the Device Messages The commands used in the following examples are not in every case implemented in the instrument. Common commands Common commands consist of a header preceded by an asterisk "*" and one or several parameters, if any.
Page 373 R&S FSP Remote Control – Basics Structure and Syntax of the Device Messages Some key words occur in several levels within one command system. Their effect depends on the structure of the command, that is to say, at which position in the header of a command they are inserted.
