Page 85 ® The Spectrum Application R&S Measurements and Result Displays Only the signal to be measured should be visible in the diagram. An additional sig- nal would falsify the measurement. ● Define a sufficient resolution bandwidth. The resolution bandwidth should be between 1 % and 4 % of the channel band- width.
Page 86 ® The Spectrum Application R&S Measurements and Result Displays The R&S FPC opens an input field to define the channel bandwidth. 3. Enter the channel bandwidth you need. Note: The minimum channel bandwidth that you can set is 2 kHz at a span of 1 kHz.
Page 87 ® The Spectrum Application R&S Measurements and Result Displays It uses a resolution bandwidth of 1 MHz, a video bandwidth of 1 MHz and the peak detector. After finishing the automatic measurement, the R&S FPC sets the optimal reference level. Changing the span Usually, the span that the R&S FPC selects yields optimal results.
Page 88 ® The Spectrum Application R&S Measurements and Result Displays move down one position, so that the present frame is always on top of the diagram. Therefore, the sequence of frames is chronological. Selecting the spectrogram result display 1. Press the "Meas" key to open the measurement menu. 2.
Page 89 ® The Spectrum Application R&S Measurements and Result Displays The spectrogram result display is filled with new lines until you change a measure- ment setting. When you change a setting (for example the center frequency), the spectrogram clears and starts to fill again. 4.
Page 90 ® The Spectrum Application R&S Measurements and Result Displays ● Two arrows (one up, one down) indicate that the spectrogram area displayed is somewhere in the middle of the available history. ● A single up arrow in the upper right corner of the spectrogram indicates that the lowest line of the spectrogram represents the end of the history buffer.
Page 91 ® The Spectrum Application R&S Measurements and Result Displays Therefore you can adjust the color map to the overall shape of the signal you are mea- suring. Let us say, for example, that the signal has an amplitude range of about 30 dB with the maximum amplitude at about -80 dBm and the minimum amplitude at about -120 dBm.
Page 92 ® The Spectrum Application R&S Measurements and Result Displays The changes however, still do not show signal differences in detail. The only thing that happened is that the colors have shifted, in the example to purple, because the color that corresponds to the reference level has shifted from red to purple. All other colors that are part of the color scheme are still unused, because the spectro- gram level range is still the same (100 dB).
Page 93 ® The Spectrum Application R&S Measurements and Result Displays The best way to display a spectrogram is therefore to reduce the level range until the lowest signal part is mapped to the lower end of the color map and the highest signal part to the upper end of the color map.
Page 94 ® The Spectrum Application R&S Measurements and Result Displays 4. Select the "Save" softkey to store the spectrogram. Now that you have saved the spectrogram, you can replay it any time you want. The number of spectrograms that you can store on the R&S FPC internal memory depends on the other datasets that are currently on the R&S FPC.
Page 95 ® The Spectrum Application R&S Measurements and Result Displays 2. Select the "Time Line <x>" menu item. The R&S FPC opens an input field to define the position of the corresponding time line (T1 or T2). 3. Position the time line by entering a number or moving it with the rotary knob.

Page 98 ® The Spectrum Application R&S Frequency Configuration When you select the center frequency with the rotary knob or the cursor keys, the dis- tance of each step that you take depends on the span. With the rotary knob, the small- est possible step is a pixel.
Page 99 ® The Spectrum Application R&S Frequency Configuration 14.3.2 Frequency Span The span is the frequency range that the measurement covers. You can measure the full frequency range of the R&S FPC, or a smaller part of it. The span also defines which frequency information is displayed in the measurement diagram - the span is the frequency range around the center frequency...
Page 100 ® The Spectrum Application R&S Frequency Configuration Defining a start and stop frequency Defining a start a stop frequency is best suited for example for measurements on har- monics or signals whose exact frequency is unknown.

Page 110 ® The Spectrum Application R&S Bandwidth Configuration 14.5.1 Resolution Filter The resolution filter (or IF filter) is a 3 dB bandpass filter located in the IF path of the analyzer. Its bandwidth determines how well individual spectral components can be separated from each other in frequency domain measurements.

Page 155 ® Analog Demodulation R&S Bandwidth Configuration Selecting the demodulation bandwidth The demodulation bandwidth (DBW) determines the frequency range around the cen- ter frequency that is demodulated. It is not the 3 dB bandwidth of the filter but the use- ful bandwidth which is distortion-free regarding phase and amplitude. Basically, the demodulation bandwidth should be as narrow as possible to improve the S/N ratio.
Page 156 ® Analog Demodulation R&S Bandwidth Configuration Selecting the FM broadcast time The FM broadcast time parameter selects the time constant of the deemphasis filter. This deemphasis filter is commonly used in FM broadcasting to improve the S/N ratio.

Page 196 ® Remote Control R&S Remote Control Basics 19.1.4.1 Syntax for Common Commands Common (= device-independent) commands consist of a header preceded by an aster- isk (*), and possibly one or more parameters. Table 19-1: Examples of common commands *RST RESET Resets the instrument.
Page 197 ® Remote Control R&S Remote Control Basics Case-insensitivity Upper case and lower case notation only serves to distinguish the two forms in the manual, the instrument itself is case-insensitive. Numeric Suffixes If a command can be applied to multiple instances of an object, e.g. specific channels or sources, the required instances can be specified by a suffix added to the command.
Page 198 ® Remote Control R&S Remote Control Basics Optional mnemonics with numeric suffixes Do not omit an optional mnemonic if it includes a numeric suffix that is relevant for the effect of the command. Example: Definition:DISPlay[:WINDow<1...4>]:MAXimize <Boolean> Command: DISP:MAX ON refers to window 1. In order to refer to a window other than 1, you must include the optional WINDow parameter with the suffix for the required window.

According to SCPI, this unit is represented by the PCT string. Example: HCOP:PAGE:SCAL 90PCT Special Numeric Values The following mnemonics are special numeric values.
Page 200 ® Remote Control R&S Remote Control Basics Example: Setting command: HCOPy:DEV:COL ON Query: HCOPy:DEV:COL? Response: 1 Text Parameters Text parameters observe the syntactic rules for mnemonics, i.e. they can be entered using a short or long form. Like any parameter, they have to be separated from the header by a white space.
Page 201 ® Remote Control R&S Remote Control Basics Table 19-2: Syntax elements The colon separates the mnemonics of a command. The semicolon separates two commands of a command line. It does not alter the path. The comma separates several parameters of a command. The question mark forms a query.
Page 202 ® Remote Control R&S Remote Control Basics 19.1.4.5 Structure of a Command Line A command line may consist of one or several commands. It is terminated by one of the following: ● <New Line> ● <New Line> with EOI ● EOI together with the last data byte Several commands in a command line must be separated by a semicolon ";".
Page 203: Command Sequence And Synchronization

® Remote Control R&S Status Reporting System 19.17 Status Reporting System The status reporting system stores all information about the present operating state of the instrument, including errors that have occurred. The R&S FPC stores this informa- tion in the status registers and in the error queue. You can query the contents of the status registers and the error queue via a remote control connection.

Page 355 ® Remote Control R&S Status Reporting System Usage: Event STATus:QUEue[:NEXT]? This command returns the earliest entry of the error queue and deletes it. Positive error numbers indicate device-specific errors, negative error numbers are error messages defined by SCPI. If the error queue is empty, the error number 0, "No error", is returned.
Page 356 ® Remote Control R&S Status Reporting System Parameters: <SumBit> <numeric value> (integer) Range: 0 to 65535 STATus:OPERation:PTRansition <SumBit> This command controls the Positive TRansition part of the OPERation register. Setting a bit causes a 0 to 1 transition in the corresponding bit of the associated regis- ter.
Page 357 ® Remote Control R&S Status Reporting System The ENABle part allows true conditions in the EVENt part of the status register to be reported in the summary bit. If a bit is 1 in the enable register and its associated event bit transitions to true, a positive transition will occur in the summary bit reported to the next higher level.
