Page 69: Measurements And Result Displays
Configuration", on page 90. 9.2 Measurements and Result Displays The R&S FPC1000 allows you to measure a signal in the frequency domain or the time domain. You can also equip the R&S FPC1000 with optional extended measurement functions like ACLR or OBW measurements. These measurements provide settings and tools for special measurement tasks.
Page 70 The measurement in the frequency domain is the default measurement mode. Time domain measurements In the time domain, the R&S FPC1000 analyzes the characteristics of a signal at a par- ticular frequency over time. The span during time domain measurements is 0...
Page 71 Other signals in the frequency spectrum don't show in the results. When measuring the spectrum within a channel, the R&S FPC1000 uses a resolution bandwidth that is small compared to the channel bandwidth. It then determines the total power of the channel by integrating the results on the trace.
Page 72 The span is always coupled to the channel bandwidth (span = 1.2 to 5 x channel band- width, depending on the channel bandwidth). When you change the channel band- width, the R&S FPC1000 automatically adjusts the span, but not the other way around. 9.2.1.2 Configuration Access: "Meas"...
Page 73 If the measurement is not according to the selected standard anymore (for exam- ple if you change a parameter), the R&S FPC1000 shows a blue dot in front of the standard display. User Manual 1178.4130.02 ─ 02 北京海洋兴业科技股份有限公司（证券代码：839145）...
Page 74 R&S FPC1000, even if the trace is within the measurement diagram. To prevent an overload, measure the occupied bandwidth with the largest resolution bandwidth possible using the peak detector. If you set these parameters, it is not possible for the trace to exceed the reference level.
Page 75 You can define a percentage between 10 % and 99 %. Numerous standards require an occupied bandwidth of 99 %. After entering the channel bandwidth, the R&S FPC1000 automatically selects the measurement parameters so that you can attain the best result.
Page 76 1. Press the "Meas" key to open the measurement menu. 2. Select the "% Power Bandwidth" menu item. The R&S FPC1000 opens an input field to define the power percentage. 3. Enter the power percentage the measurement requires. The R&S FPC1000 now displays the occupied bandwidth graphically in the trace window and numerically above the trace window.
Page 77 If the measurement is not according to the selected standard anymore (for exam- ple if you change a parameter), the R&S FPC1000 shows a blue dot in front of the standard display. Defining the reference level reference level is the power level that the R&S FPC1000 expects at the RF input.
Page 78 A third dimension shows the amplitude for each frequency by mapping different colors to every power level. The color the R&S FPC1000 assigns to a power level that was measured depends on: ●...
Page 79 You can see that the spectrogram result display fills up, as each sweep adds an additional line to the spectrogram. When you are in single sweep mode, the R&S FPC1000 does not add a line to the spectrogram until you initiate the next single sweep.
Page 80 1. Press the "Meas" key to open the measurement menu. 2. Select the "Full Screen" menu item. The R&S FPC1000 now uses the full diagram area of the screen for the spectro- gram. The number of lines in the spectrogram and therefore the displayed time period more than doubles.
Page 81 9.2.3.2 Color Definition Colors are an important element of the spectrogram. The R&S FPC1000 provides vari- ous features to customize the display for the best viewing results. Selecting a color scheme The first and most obvious way to adjust colors is to select a different color scheme.
Page 82 In the example, the reference level should be at about -80 dBm. 4. Enter the reference level you need. The R&S FPC1000 now shifts the reference level of the spectrogram to the value you have entered. Note that the spectrogram reference level does not affect the...
Page 83 6. Therefore, set the level range to 40 dB to cover the complete level range of the sig- nal. As the level range is now adjusted, the R&S FPC1000 is able to map its complete color range to the level range of the signal.
Page 84 Note: You can also use the "Auto Range" menu item to adjust the displayed level range. In that case, the R&S FPC1000 selects a level range that best suits the cur- rently measured signal.
Page 85 To find a particular point in time and display the corresponding spectrum, you can use two time lines. When you enter the playback mode, the R&S FPC1000 displays two time lines in the spectrogram. Both time lines (T1 and T2) correspond to an absolute time value, whose position refers to the most recent time frame (top of the diagram).
Page 86 4. Press the "Marker" key. The R&S FPC1000 activates a marker and sets it on the peak level of the currently displayed spectrum. 5. Use the rotary knob or the cursor keys to move the marker on the x-axis to the fre- quency you want to analyze, or enter the frequency directly with the number keys.
Page 87: Frequency Configuration
Regarding the frequency information, a typical measurement task does not require you to measure the characteristics of the complete frequency range supported by the R&S FPC1000. Instead, it is usually sufficient to measure the characteristics of a limi- ted frequency range only.
Page 88 The R&S FPC1000 opens an input field to define the center frequency. Tip: When you press the "Freq" key, the R&S FPC1000 automatically opens an input field to define the center frequency. If the input field is inactive, you can open it with the "Center Freq"...
Page 89 The R&S FPC1000 adjusts the step size accordingly. If you set the step size to 10 % of the span or to the center frequency, the R&S FPC1000 sets the step size internally. Manually defining the step size opens an input field to define the step size.
Page 90 The span is the frequency range that the measurement covers. You can measure the full frequency range of the R&S FPC1000, or a smaller part of it. The span also defines which frequency information is displayed in the measurement diagram - the span is the...
Page 91 The R&S FPC1000 already comes with an assortment of channel tables that you can use without doing anything. If you want to test transmission standards that are not lis- ted, you can also create your own channel tables with the "Channel Table Editor"...
Page 92: Amplitude Configuration
In addition to measuring the frequency of a signal, the other main function of a spec- trum analyzer is to measure level characteristics of the signal. The R&S FPC1000 provides several settings that have an effect on the way the level is measured and how level values are displayed.
Page 93: Reference Level
If you need an input impedance of 75 Ω, you have to connect one of the supported matching pads to the RF input. When one of the supported matching pads is connec- ted, you can change the input impedance. The R&S FPC1000 in that case automati- cally considers the conversion factor.
Page 94 The R&S FPC1000 opens an input field to define the reference offset. 4. Enter the required reference level offset. The R&S FPC1000 adjusts the position of the trace and scale of the y-axis as you apply the changes. A blue dot in front of the "Ref:" label in the status bar indicates that a level offset is active.
Page 95 The R&S FPC1000 adjusts the position of the trace accordingly. 9.4.2 Measurement Sensitivity The R&S FPC1000 provides several ways to improve (control) the sensitivity of a mea- surement. RF attenuator The internal RF attenuator is a hardware component to control measurement sensitiv- ity.
Page 96 FPC1000 Amplitude Configuration 2. Select the "Attenuator" menu item to open the attenuator menu. 3. The R&S FPC1000 provides several attenuation modes. ● "Manual Att <x> dB" Defines the attenuation manually in 5 dB steps. The range is from 0 dB to 40 dB.
Page 97 The preamplifier allows you to detect even weak signals. ● The preamplifier reduces the noise figure of the R&S FPC1000 and thus increases its sensitivity. Thus, it is recommended to use the preamplifier for measurements that require a high sensitivity.
Page 98 DUT and RF input of the R&S FPC1000. You can create and edit transducer factor with the R&S InstrumentView software pack- age and then transfer them into the internal memory of the R&S FPC1000. Each trans- ducer factor can consist of up to 1000 reference values.
Page 99 ● W/m2 The unit dB does not change the unit set on the R&S FPC1000. It can be used, for example, to compensate for frequency-dependent loss and gain at the input of the R&S FPC1000. The units dBμV/m and dBμA/m convert the output power of an antenna into electric or magnetic field strength.
Page 100: Bandwidth Configuration
If the unit of the transducer is dBμV/m or dBμA/m, this unit is also used for the R&S FPC1000 level display. This means that both the level axis of the diagram and the level at the marker position are assigned the unit of the transducer. If dBμV/m is selected as the transducer unit, a switch to absolute level indication in V/m is possible.
Page 101 "RBW: Manual" Opens an input field to select one of the available bandwidths. If you enter a bandwidth that the R&S FPC1000 does not support, the R&S FPC1000 rounds to the next available bandwidth. Refer to the data sheet for more information on available resolution bandwidths Note that you have to select the 200 kHz bandwidth manually with the number keys.
Page 102 Automatic adjustment of the sweep time In its default mode, the R&S FPC1000 automatically adjusts the sweep time when you change the resolution bandwidth. This ensures that the settling time required for the selected resolution filter is properly taken into account.

Page 104 R&S FPC1000 adjusts the measurement time accordingly. In the time domain (span = 0), the R&S FPC1000 shows the video voltage over time. The horizontal axis becomes a time axis that starts at 0 s and ends at the measure- ment time that you have selected.
Page 105: Trigger Configuration
A measurement starts when the voltage of the video signal exceeds a certain level. When you select the video trigger, the R&S FPC1000 opens an input field to define the trigger level that the video signal must meet or exceed. The video trigger level is a percentage of the diagram height (0 % to 100 %).

Page 107 R&S FPC1000 evaluates and displays the measurement data differently. Selecting a trace The R&S FPC1000 can display up to two traces at the same time, each with a different configuration. Before you configure a trace, you have to select the trace whose attributes you would like to change.
Page 108 Memory Traces....................... 96 9.8.1 Trace Mode The trace mode determines the way the R&S FPC1000 writes or displays the trace or which results are displayed. Note that each time you select another trace mode, the R&S FPC1000 clears the trace memory.
Page 109 The only exception is when you change the scale of the x- axis - in that case, the R&S FPC1000 writes a new trace. The fact that the dis- played trace no longer matches the current measurement settings is indicated by an asterisk ( ) in the diagram.
Page 110 However, the bandwidth occupied by the signal to be measured should at least equal the frequency covered by a trace pixel or the selected resolution bandwidth (whichever is larger). Otherwise, the power the R&S FPC1000 shows is too low because there are spectral components within the frequency range covered by the pixel that do not originate from the signal you want to observe (e.g.
Page 111 9.8.3 Memory Traces Working with memory traces You can save the image of both traces to the memory of the R&S FPC1000 and later restore it, compare it to a live trace or apply trace mathematics. The memory trace has a different shade of color to distinguish it from the live traces.
Page 112: Marker Configuration
The R&S FPC1000 saves the selected trace. 3. Select the "Trace Math" menu item. The R&S FPC1000 opens a submenu to select mathematical operations to be applied to the traces. 4. Select the "Trace - Memory " or the "Memory - Trace " menu item.
Page 113 FPC1000 Marker Configuration The R&S FPC1000 has six markers, five of which can be used as either markers or delta markers. Markers show absolute values, delta markers show values relative to the first marker (marker 1 or "M1"). The first marker (reference marker) is always a nor- mal marker.
Page 114 Marker Search Ranges..................101 9.9.1 Marker Positioning You can position the markers on any trace point you like. The R&S FPC1000 also pro- vides some useful tools to position markers automatically. Positioning a marker 1. Press the "Mkr" key to open the marker menu.
Page 115 2. Select the marker or delta marker you want to remove with the corresponding "Marker <x>" softkey. The R&S FPC1000 selects the corresponding marker or delta marker. 3. Remove the marker or delta marker by selecting the corresponding softkey again.
Page 116 The R&S FPC1000 deletes all markers and delta markers. 9.9.2 Automatic Marker Positioning The R&S FPC1000 has several useful tools to position markers automatically (for example on a peak level) and tools that change instrument settings based on the cur- rent marker position.
Page 117 The R&S FPC1000 opens a submenu to configure search range 1. 4. Select the "Lower Limit ..." menu item. The R&S FPC1000 opens an input field to set the lower limit of search range 1. 5. Enter the lower limit of the search range you want to use.
Page 118: Marker Functions
(absolute or relative). To stabilize the noise power display, the R&S FPC1000 uses the pixel the marker is on and four pixels to the right and four pixels to the left of the marker pixel.
Page 119 With the frequency counter, however, you can get a more accurate result of the fre- quency that the marker is positioned on. If the frequency counter is active, the R&S FPC1000 stops the measurement at the marker position for a short time and measures the frequency using the internal reference frequency.
Page 120 You can listen to the demodulated signal with the internal speaker or headphones that you can connect to the 3.5 mm headphone jack on the front of the R&S FPC1000. When demodulating an AM modulated signal, the R&S FPC1000 turns the video volt- age into an audible sound.
Page 121: Display Lines
The R&S FPC1000 opens an input field to define the demodulation time. 4. Enter the demodulation time you want to use. Note: The range is from 100 ms to 500 s. In the time domain, the R&S FPC1000 demodulates continuously. The demodulation time has no effect in that case.
Page 122: Limit Lines
1. Press the "Lines" key to open the lines menu. 2. Select the "Display Line" menu item. The R&S FPC1000 displays the display line as a blue horizontal line. It shows the vertical position (usually a level value) of the line in a table above the diagram area.
Page 123 Values that define the vertical characteristics are always level values in dB. If the scal- ing of the vertical axis is a linear one (units V or W), the R&S FPC1000 automatically switches to a logarithmic scaling after you turn on the limit line.
Page 124 6. Select one of the available files and confirm the selection with the "Load" menu item. The R&S FPC1000 displays the limit line. In the diagram area, the limit line is rep- resented by a red line whose shape depends on the limits If you have selected a limit line that is not compatible to the current diagram scale, the R&S FPC1000 displays a message that it cannot apply the selected limit line.
Page 125 As long as the signal does not violate the limit line, the R&S FPC1000 shows a "Pass" message in the measurement diagram. As soon as one single value (= one pixel) is outside of the limits, the R&S FPC1000 displays a "Fail" message in the diagram area.
Page 126: The Receiver Application
The receiver application measures the power level of a specific frequency or a custom- ized set of frequencies instead of sweeping over (parts of) the frequency spectrum. The R&S FPC1000 shows the results in result displays that have been designed for just such measurement tasks.
Page 127 Selecting fixed frequency measurements 1. Press the "Meas" key to open the measurement menu. 2. Select the "Fixed Frequency" menu item. The R&S FPC1000 shows the signal level measured at the current receiver fre- quency. 10.1.2 Frequency Scan Access: "Meas" > "Frequency Scan"...
Page 128 The space between the receiver frequencies is not considered in the measurement. The R&S FPC1000 shows the results for a frequency scan in a graphical result display. The horizontal axis in that display represents the frequency spectrum covered by the scan.

Page 159 It is recommended that you use the R&S VISA driver. You can get R&S VISA, includ- ing the documentation, from the Rohde & Schwarz internet pages. Resetting the R&S FPC1000 Manual operation is designed for maximum operating convenience. The priority of remote control, however, is the "predictability" of the device status.
Page 160 Remote Control FPC1000 Remote Control Basics 13.1.1.3 Protocols VXI-11 basics The VXI-11 standard is based on the ONC-RPC protocol which in turn relies on TCP/IP as the network/transport layer. The TCP/IP network protocol and the associated net- work services are preconfigured. TCP/IP ensures connection-oriented communication, where the order of the exchanged messages is adhered to and interrupted links are identified.

Remote Control FPC1000 Remote Commands of the Spectrum Application 13.9 Applications ......................179 INSTrument[:SELect] INSTrument[:SELect] <Application> This command selects the measurement application. Parameters: <Application> ADEMod Selects the analog demodulation application. DDEMod Selects the digital demodulation application. RECeiver Selects the receiver application.
Page 195 This command adjusts the reference level to the measured signal power. This automatic routine makes sure that the signal power level does not overload the R&S FPC1000 or limit the dynamic range by a too small S/N ratio. To determine the best reference level, the R&S FPC1000 aborts current measure- ments and performs a series of test sweeps.
Page 196 Note that the command only checks the parameters that are defined by the standard. Suffix: <n>, <m> irrelevant Return values: <State> R&S FPC1000 settings violate a standard configuration. R&S FPC1000 settings comply with the standard. //Query compliance to the standard currently in use Example: CALC:MARK:FUNC:POW:PRES '3GPP WCDMA.chpstd' CALC:MARK:FUNC:POW:PRES:CHEC?
