R&S®FPL1000 The Spectrum Application (RF Measurements) Measurements and Results 7.2.6.1 About the Measurement The Spectrum Emission Mask (SEM) measurement defines a measurement that monitors compliance with a spectral mask. The mask is defined with reference to the input signal power. The R&S FPL1000 allows for a flexible definition of all parameters in the SEM measurement.
R&S®FPL1000 The Spectrum Application (RF Measurements) Measurements and Results Example: For example, in Figure 7-22, "31 < P < 39" is indicated as the used power class is defined from 31 to 39. Figure 7-22: Spectrum Emission Mask result displays In addition to the graphical results of the SEM measurement displayed in the diagram, a result summary is displayed to evaluate the limit check results (see also "Limit Lines in SEM Measurements" on page 294).

R&S®FPL1000 The Spectrum Application (RF Measurements) Measurements and Results Limit Lines in SEM Measurements For the R&S FPL1000, the spectrum emission mask is defined using limit lines. Limit lines allow you to check the measured data (that is, the trace results) against specified limit values. Generally, it is possible to define limit lines for any measurement in the Spectrum application application using the LINES function.
R&S®FPL1000 The Spectrum Application (RF Measurements) Measurements and Results Limit check type Pass/fail criteria Limit line definition "Relative with function f(x)" If the power exceeds both the absolute and the relative limits, the check fails (see Relative limit line functions below) Defined by the maximum of the absolute or relative start and stop limit values for each range. Thus, the start or stop point of the limit range, or both, are variable (since the maximum can vary).
R&S®FPL1000 The Spectrum Application (RF Measurements) Measurements and Results Although a margin functionality is not available for the limit check, a margin (threshold) for the peak values to be displayed in the Result Summary can be defined. (In the "List Evaluation" settings, see "List Evaluation (Results Configuration)" on page 313). Fast SEM Measurements To improve the performance of the R&S FPL1000 for spectrum emission mask measurements, a "Fast SEM" mode is available.
R&S®FPL1000 The Spectrum Application (RF Measurements) 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.

R&S®FPL1000 The Spectrum Application (RF Measurements) Measurements and Results 7.2.9.1 About the Measurement With this measurement it is possible to measure the harmonics easily, for example from a VCO. In addition, the total harmonic distortion (THD) is calculated. For measurements in the frequency domain, the Harmonic Distortion measurement starts with an automatic search for the first harmonic (= peak) within the set frequency range.
R&S®FPL1000 The Spectrum Application (RF Measurements) Measurements and Results As shown in Figure 7-29, the level of the 2nd harmonic drops by 20 dB if the level of the fundamental wave is reduced by 10 dB. Figure 7-29: Extrapolation of the 1st and 2nd harmonics to the 2nd harmonic intercept at 40 dBm The following formula for the obtainable harmonic distortion d2 in dB is derived from the straight-line equations and the given intercept point: d2 = S.H.I – PI (1) where: d2 = harmonic distortion S.H.
R&S®FPL1000 The Spectrum Application (RF Measurements) Measurements and Results ● Select an RF attenuation which is high enough to measure the harmonic ratio only. The maximum harmonic distortion is obtained if the level of the harmonic equals the intrinsic noise level of the receiver. The level applied to the mixer, according to (2), is: At a resolution bandwidth of 10 Hz (noise level -143 dBm, S.H.I. = 40 dBm), the optimum mixer level is – 51.5 dBm.

R&S®FPL1000 The Spectrum Application (RF Measurements) Measurements and Results 7.2.10.1 About the TOI Measurement If several signals are applied to a transmission two-port device with nonlinear characteristic, intermodulation products appear at its output at the sums and differences of the signals. The nonlinear characteristic produces harmonics of the useful signals which intermodulate at the characteristic.
R&S®FPL1000 The Spectrum Application (RF Measurements) Measurements and Results Figure 7-30: Intermodulation products Ps1 and Ps2 The intermodulation product at fi2 is generated by mixing the 2nd harmonic of useful signal PU2 and signal PU1. Tthe intermodulation product at fi1 is generated by mixing the 2nd harmonic of useful signal PU1 and signal PU2.
R&S®FPL1000 The Spectrum Application (RF Measurements) Measurements and Results Figure 7-31: Dependency of intermodulation products on level of useful signals The useful signals at the two-port output increase proportionally with the input level as long as the two-port is in the linear range. A level change of 1 dB at the input causes a level change of 1 dB at the output. Beyond a certain input level, the two-port goes into compression and the output level stops increasing.
R&S®FPL1000 The Spectrum Application (RF Measurements) Measurements and Results Intermodulation-free dynamic range The "Intermodulation-free dynamic range", i.e. the level range in which no internal intermodulation products are generated if two-tone signals are measured, is determined by the third order intercept point, the phase noise and the thermal noise of the signal analyzer. At high signal levels, the range is determined by intermodulation products.

The level of a signal analyzer's intrinsic intermodulation products depends on the RF level of the useful signals at the input mixer. When the RF attenuation is added, the mixer level is reduced and the intermodulation distance is increased. With an additional RF attenuation of 10 dB, the levels of the intermodulation products are reduced by 20 dB.

R&S®FPL1000 The Spectrum Application (RF Measurements) Receiving Data Input and Providing Data Output RF Input Protection The RF input connector of the R&S FPL1000 must be protected against signal levels that exceed the ranges specified in the data sheet. Therefore, the R&S FPL1000 is equipped with an overload protection mechanism. This mechanism becomes active as soon as the power at the input mixer exceeds the specified limit. It ensures that the connection between RF input and input mixer is cut off.

R&S®FPL1000 The Spectrum Application (RF Measurements) Bandwidth, Filter and Sweep Configuration 7.6 Bandwidth, Filter and Sweep Configuration The basic bandwidth, filter and sweep settings that apply to most measurements are described here. These parameters define how the data is measured: how much data is collected internally and which filters are used. ● ● ● Impact of the Bandwidth, Filter and Sweep Settings.............................................390 Bandwidth, Filter and Sweep Settings..........
R&S®FPL1000 The Spectrum Application (RF Measurements) Bandwidth, Filter and Sweep Configuration rated is determined by the resolution bandwidth. Selecting a resolution bandwidth that is too large may make it impossible to distinguish between spectral components, i.e. they are displayed as a single component. Smaller resolution bandwidths, however, increase the required "Sweep Time" .
R&S®FPL1000 The Spectrum Application (RF Measurements) 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. However, the VBW is still considered when calculating the "Sweep Time" . This leads to a longer "Sweep Time" for small VBW values.
R&S®FPL1000 The Spectrum Application (RF Measurements) Bandwidth, Filter and Sweep Configuration 7.6.1.5 How Data is Measured: the Sweep Type In a standard analog frequency sweep, the local oscillator of the analyzer sweeps the applied signal quasi analog from the start to the stop frequency to determine the frequency spectrum. Alternatively, the analyzer can sample signal levels over time at a defined frequency and transform the data to a spectrum by Fast Fourier Transformation (FFT).
R&S®FPL1000 The Spectrum Application (RF Measurements) Bandwidth, Filter and Sweep Configuration In "Auto" mode, a medium-sized prefilter is used. 7.6.1.6 Which Data May Pass: Filter Types While the filter is irrelevant when measuring individual narrowband signals (as long as the signal remains within the RBW), the measurement result for broadband signals is very dependant on the selected filter type and its shape. If the filter is too narrow, the signal is distorted by the filter.
R&S®FPL1000 The Spectrum Application (RF Measurements) Bandwidth, Filter and Sweep Configuration 7.6.1.8 How Much Data is Measured: Sweep Points and Sweep Count By default, 1001 data points are determined in a single sweep. During the next sweep, 1001 new data points are collected, and so on. The number of sweep points defines how much of the entire span is covered by a single data point.

VBW) Recommended for pulse signals "Noise[10]" "Video Bandwidth" = "Resolution Bandwidth/10" Recommended for noise measurements "Manual" The coupling ratio is defined manually. The RBW/VBW ratio can be set in the range of 0.001 to 1000.
R&S®FPL1000 The Spectrum Application (RF Measurements) Bandwidth, Filter and Sweep Configuration For spectrogram displays, the sweep count determines how many sweeps are combined in one frame in the spectrogram; that is: how many sweeps the R&S FPL1000 performs to plot one trace in the spectrogram result display.

R&S®FPL1000 The Spectrum Application (RF Measurements) Trigger and Gate Configuration Trigger Source The trigger source defines which source must fulfill the condition that triggers the measurement.
R&S®FPL1000 The Spectrum Application (RF Measurements) Trigger and Gate Configuration Example: In the following example, the second possible trigger event is ignored as the signal does not exceed the hysteresis (threshold) before it reaches the trigger level again on the rising edge. On the falling edge, however, two trigger events occur as the signal exceeds the hysteresis before it falls to the trigger level the second time.
R&S®FPL1000 The Spectrum Application (RF Measurements) Trigger and Gate Configuration Drop-out times for falling edge triggers If a trigger is set to a falling edge ( "Slope" = "Falling" , see " Slope " on page 413) the measurement is to start when the power level falls below a certain level. This is useful, for example, to trigger at the end of a burst, similar to triggering on the rising edge for the beginning of a burst.

Remote command: TRIGger[:SEQuence]:IFPower:HOLDoff on page 663 Slope For all trigger sources except time, you can define whether triggering occurs when the signal rises to the trigger level or falls down to it. For gated measurements in "Edge" mode, the slope also defines whether the gate starts on a falling or rising edge.
R&S®FPL1000 The Spectrum Application (RF Measurements) Trigger and Gate Configuration To define an external trigger: 1. Connect an external device that will provide the trigger signal to one of the TRIGGER INPUT / OUTPUT connectors on the R&S FPL1000 (for details see the R&S FPL1000 "Getting Started" manual). 2.

R&S®FPL1000 The Spectrum Application (RF Measurements) Trigger and Gate Configuration Example: By using a gate in sweep mode and stopping the measurement while the gate signal is inactive, the spectrum for pulsed RF carriers can be displayed without the superposition of frequency components generated during switching. Similarly, the spectrum can also be analyzed for an inactive carrier. The sweep can be controlled by an external gate or by the internal power trigger.

R&S®FPL1000 The Spectrum Application (RF Measurements) Trace Configuration With logarithmic averaging, the dB values of the display voltage are averaged or subtracted from each other with trace mathematical functions. With linear averaging, the level values in dB are converted into linear voltages or powers before averaging.

R&S®FPL1000 The Spectrum Application (RF Measurements) Trace Configuration Frames are sorted in chronological order, beginning with the most recently recorded frame at the top of the diagram (frame number 0). With the next sweep, the previous frame is moved further down in the diagram, until the maximum number of captured frames is reached. The display is updated continuously during the measurement, and the measured trace data is stored.
R&S®FPL1000 The Spectrum Application (RF Measurements) Trace Configuration Tracking absolute time - timestamps Alternatively to the frame count, the absolute time (that is: a timestamp) at which a frame was captured can be displayed. While the measurement is running, the timestamp shows the system time. In single sweep mode or if the sweep is stopped, the timestamp shows the time and date at the end of the sweep.Thus, the individual frames can be identified by their timestamp or their frame count.
R&S®FPL1000 The Spectrum Application (RF Measurements) Trace Configuration Uses a color range from black over green to light turquoise with shades of green in between. Dark colors indicate low levels, light colors indicate high ones. ● Grayscale Shows the results in shades of gray. Dark gray indicates low levels, light gray indicates high ones.
R&S®FPL1000 The Spectrum Application (RF Measurements) Trace Configuration Example: In the color map based on the linear color curve, the range from -100 dBm to -60 dBm is covered by blue and a few shades of green only. The range from -60 dBm to -20 dBm is covered by red, yellow and a few shades of green. Figure 7-52: Spectrogram with (default) linear color curve shape = 0 The sample spectrogram is dominated by blue and green colors.
R&S®FPL1000 The Spectrum Application (RF Measurements) Trace Configuration Figure 7-53: Spectrogram with non-linear color curve (shape = -0.5) Markers in the Spectrogram Markers and delta markers are shaped like diamonds in the spectrogram. They are only displayed in the spectrogram if the marker position is inside the visible area of the spectrogram. If more than two markers are active, the marker values are displayed in a separate marker table.
R&S®FPL1000 The Spectrum Application (RF Measurements) Trace Configuration 7.10.2.2 Spectrogram Settings Access: TRACE > "Spectrogram Config" The individual settings available for spectrogram display are described here.

R&S®FPL1000 The Spectrum Application (RF Measurements) Trace Configuration To set a marker in the spectrogram 1. While a spectrogram is displayed, select the MARKER key. 2. Select a "Marker" softkey. 3. Enter the frequency or time (x-value) of the marker or delta marker. 4. Enter the frame number for which the marker is to be set, for example 0 for the current frame, or -2 for the second to last frame.
R&S®FPL1000 The Spectrum Application (RF Measurements) Trace Configuration To select a color scheme You can select which colors are assigned to the measured values. ► In the "Color Mapping" dialog box, select the option for the color scheme to be used. Editing the value range of the color map The distribution of the measured values is displayed as a histogram in the "Color Mapping" dialog box. To cover the entire measurement value range, make sure the first and last bar of the histogram are included.
R&S®FPL1000 The Spectrum Application (RF Measurements) Trace Configuration Example: The color map starts at -110 dBm and ends at -10 dBm (that is: a range of 100 dB). In order to suppress the noise, you only want the color map to start at -90 dBm. Thus, you enter 10% in the "Start" field. The R&S FPL1000 shifts the start point 10% to the right, to -90 dBm.

R&S®FPL1000 Troubleshooting Miscellaneous Troubleshooting Hints 3. On the remote channel performing the measurement, send the SCPI command ABORt to abort the current measurement and reset the trigger system. 4. If the R&S FPL still does not react to the remote commands, switch it off and back on. Ignored commands When a remote command attempts to define incompatible settings, the command is ignored and the instrument status remains unchanged, i.e. other settings are not automatically adapted.
R&S®FPL1000 Troubleshooting Miscellaneous Troubleshooting Hints Data capturing takes too long Particularly for FFT sweeps, the time required to process the data may be considerably longer than the time required to capture the data. Thus, if you only consider the defined sweep time, you may assume an error has occurred if the measurement takes longer than expected.
R&S®FPL1000 Troubleshooting Collecting Information for Technical Support If you want to apply the changed transducer values after recalling the save set you must force the application to reload the transducer file. To do so, simply open the "Edit Transducer" dialog box (see Chapter 6.3.6.2, "Transducer Settings", on page 148) and toggle the "X-Axis" option from "Lin" to "Log" and back.
