Page 238 Small signals can be swamped by noise and therefore cannot be measured. For sig- nals that are just above the intrinsic noise, the accuracy of the level measurement is influenced by the intrinsic noise of the R&S FPL1000. The displayed noise level of a signal analyzer depends on its noise figure, the selected RF attenuation, the selected reference level, the selected resolution and video band- width and the detector.
Page 239 467). The traces of consecutive sweeps are averaged. To perform averaging, the R&S FPL1000 automatically switches on the sample detector. The RF signal, therefore, can be more clearly distinguished from noise. Figure 7-2: RF sine wave signal with low S/N ratio with an averaged trace 6.

Page 251 Therefore, the R&S FPL1000 provides a measurement for absolute and relative power in zero span. In the following example, the measurement is performed using a GSM burst.
Page 252 9. Measure the power during the deactivation phase of the burst by switching the trig- ger slope to "Falling" (TRIG > "Trigger/ Gate Config" ). The R&S FPL1000 initiates triggering in response to the falling edge of the burst. This shifts the burst to the left-hand side of the measurement diagram. The power is measured in the deactivation phase.

Page 296 313). Fast SEM Measurements To improve the performance of the R&S FPL1000 for spectrum emission mask mea- surements, a "Fast SEM" mode is available. If this mode is activated, several consecu- tive ranges with identical sweep settings are combined to one sweep internally, which makes the measurement considerably faster.
Page 297 ® The Spectrum Application (RF Measurements) R&S FPL1000 Measurements and Results Consequences When the "Fast SEM" mode is activated, the ranges for which these criteria apply are displayed as one single range. The sweep time is defined as the sum of the individual sweep times, initially, but can be changed.

Page 382 Reference level offset If the signal is attenuated or amplified before it is fed into the R&S FPL1000, you can define an (arithmetic) offset to the reference level so the application shows correct power results. All displayed power level results are shifted by this value, and the scal- ing of the y-axis is changed accordingly.
Page 383 Note, however, that the internal reference level (used to adjust the hardware settings to the expected signal optimally) ignores any "Reference Level Offset" . Thus, it is impor- tant to keep in mind the actual power level the R&S FPL1000 must handle, and not to rely on the displayed reference level.
Page 384 ® The Spectrum Application (RF Measurements) R&S FPL1000 Amplitude and Vertical Axis Configuration Depending on the type of measurement you must find a compromise between a low noise floor and high intermodulation levels, and protecting the instrument from high input levels. You achieve this best by letting the R&S FPL determine the optimum level automatically (see "...

These parameters define how the data is measured: how much data is collected internally and which filters are used.
Page 391 60 dB bandwidth to the 3 dB bandwidth (= shape factor). For the R&S FPL1000, the shape factor for bandwidths is < 5, i.e. the 60 dB bandwidth of the 30 kHz filter is <150 kHz.
Page 392 ® The Spectrum Application (RF Measurements) R&S FPL1000 Bandwidth, Filter and Sweep Configuration RMS/Average detector and VBW If an RMS or average detector is used, the video bandwidth in the hardware is bypassed. Thus, duplicate trace averaging with small VBWs and RMS or average detector no longer occurs.
Page 393 RBWs. Which sweep mode is appropriate for the current measurement depends on the span, RBW, VBW and "Sweep Time" settings. The R&S FPL1000 automatically selects the appropriate sweep type.

Page 438 Frequency resolution is further restricted by the RBW and sweep time settings. To determine the frequency of a signal point accurately without changing the sweep settings, the R&S FPL1000 is equipped with a signal counter. The signal counter sets User Manual 1178.3370.02 ─ 03...
Page 439 Signal counting can be performed explicitly at the current marker position ( "Signal Count" marker function), or implicitly by the R&S FPL1000 for certain functions. Signal counting is only possible while the instrument is not sweeping. Thus, to perform a signal count for a marker, the sweep is stopped at the marker position.
Page 440 ● Trace averaging: In the default setting, the R&S FPL1000 uses the sample detector for the noise function. With the sample detector, you can set the trace to "Average" mode to sta- bilize the measured values. When the RMS detector is used, trace averaging pro- duces noise levels that are too low and cannot be corrected.
Page 441 For span > 0, the measured values are averaged versus time (after a sweep). The R&S FPL1000 noise figure can be calculated from the measured power density level. It is calculated by deducting the set RF attenuation (RF Att) from the displayed noise level and adding 174 to the result.

Page 461 (not available for SEM) Calculates the root mean square of all samples contained in a sweep point. To this effect, R&S FPL1000 uses the linear voltage after envelope detection. The sampled linear values are squared, summed and the sum is divided by the number of samples (= root mean square).
Page 462 You can define the trace detector to be used for the individual traces manually, or the R&S FPL1000 can select the appropriate detector automatically. The detectors of the R&S FPL1000 are implemented as pure digital devices. All detec- tors work in parallel in the background, which means that the measurement speed is independent of the detector combination used for different traces.
Page 463 Max Hold The maximum value is determined over several measurements and displayed. The R&S FPL1000 saves the sweep result in the trace memory only if the new value is greater than the previous one. This mode is especially useful with modulated or pulsed signals. The signal spectrum is filled up upon each sweep until all signal components are detected in a kind of envelope.
Page 464 ® The Spectrum Application (RF Measurements) R&S FPL1000 Trace Configuration  Trace MeasValue  Trace Figure 7-48: Equation 1 Due to the weighting between the current trace and the average trace, past val- ues have practically no influence on the displayed trace after about ten sweeps.

R&S FPL1000 is blocked for further commands. In this case, you must interrupt processing on the remote channel in order to abort the measurement.
Page 860: Miscellaneous Troubleshooting Hints
Power levels for low frequency signals not correct By default, the R&S FPL1000 uses AC coupling for RF input. For very low frequencies, the input signal may be distorted with this setting. In this case, use DC coupling instead. To change the setting, select INPUT/OUPUT > "Input Source Config" > "Radio Frequency"...
