Capture Time Signal length that has been captured
Welcome to the V5GTF measurement application
Understanding the display information
Frame Count Number of frames that have been captured
Selected Subframe Subframe considered in the signal analysis
Consecutive CC Meas Number of component carriers that are measured; the numbers in paren-
theses indicate the number of component carriers that are analyzed in a single capture
Example: 8 (3 / 3 / 2) means that 8 component carriers are analyzed in three consecutive data captures. The first two data captures analyze the first 6 component carriers (3 CCs each), while the last data capture ana­lyzes the last 2 component carriers.
The channel bar also displays information on instrument settings that affect the mea­surement results even though this is not immediately apparent from the display of the measured values (for example transducer or trigger settings). This information is dis­played only when applicable for the current measurement. For details, see the R&S FSW getting started manual.
Window title bar information
The information in the window title bar depends on the result display.
The "Constellation Diagram", for example, shows the number of points that have been measured.
Status bar information
Global instrument settings, the instrument status and any irregularities are indicated in the status bar beneath the diagram. Furthermore, the progress of the current operation is displayed in the status bar.
Regarding the synchronization state, the application shows the following labels.
●
"Sync OK" The synchronization was successful. The status bar is green.

3 Measurements and result displays

The V5GTF measurement application measures and analyzes various aspects of a V5GTF signal.
It features several result displays. Result displays are different representations of the measurement results. They are either diagrams that show the results as a graph or tables that show the results as numbers.

Measurements and result displays
Performing measurements

3.1 Selecting result displays

Access:
The R&S FSW opens a menu (the SmartGrid) to select result displays. For more infor­mation on the SmartGrid functionality, see the R&S FSW Getting Started.
In the default state of the application, it shows several conventional result displays.
●
Capture Buffer
●
EVM vs Carrier
●
Power Spectrum
●
Result Summary
●
Alloc ID vs Symbol x Carrier
●
Constellation Diagram
From that predefined state, add and remove result displays as you like from the Smart­Grid menu.
Remote command: LAYout:ADD[:WINDow]? on page 90

3.2 Performing measurements

By default, the application measures the signal continuously. In "Continuous Sweep" mode, the R&S FSW captures and analyzes the data again and again.
●
For I/Q measurements, the amount of captured data depends on the capture time.
In "Single Sweep" mode, the R&S FSW stops measuring after it has captured the data once. The amount of data again depends on the capture time.
14User Manual 1178.6327.02 ─ 06
Page 15
R&S®FSW-K118 /-K119
Refreshing captured data
You can also repeat a measurement based on the data that has already been captured with the "Refresh" function. Repeating a measurement with the same data can be use­ful, for example, if you want to apply different modulation settings to the same I/Q data.
For more information, see the documentation of the R&S FSW.

3.3 Selecting the operating mode

Access: [MODE] > "Multi-Standard Radio Analyzer Tab"
The V5GTF application is supported by the Multi Standard Radio Analyzer (MSRA).
In MSRA operating mode, only the MSRA primary actually captures data. The applica­tion receives an extract of the captured data for analysis, referred to as the application data. The application data range is defined by the same settings used to define the signal capture in "Signal and Spectrum Analyzer" mode. In addition, a capture offset can be defined, i.e. an offset from the start of the captured data to the start of the analysis interval.
Measurements and result displays
Selecting the operating mode
If a signal contains multiple data channels for multiple standards, separate applications are used to analyze each data channel. Thus, it is of interest to know which application is analyzing which data channel. The MSRA primary display indicates the data covered by each application by vertical blue lines labeled with the application name. The blue lines correspond to the channel bandwidth.
However, the individual result displays of the application need not analyze the com­plete data range. The data range that is actually analyzed by the individual result dis­play is referred to as the analysis interval.
The analysis interval is automatically determined according to the Capture Time you have defined. The analysis interval cannot be edited directly in the V5GTF application, but is changed automatically when you change the evaluation range. The currently used analysis interval (in seconds, related to capture buffer start) is indicated in the window header for each result display.
A frequent question when analyzing multi-standard signals is how each data channel is correlated (in time) to others. Thus, an analysis line has been introduced. The analysis line is a common time marker for all MSRA secondary applications. It can be posi­tioned in any MSRA secondary application or the MSRA primary and is then adjusted in all other secondary applications. Thus, you can easily analyze the results at a spe­cific time in the measurement in all secondary applications and determine correlations.
If the marked point in time is contained in the analysis interval of the secondary appli­cation, the line is indicated in all time-based result displays, such as time, symbol, slot or bit diagrams. By default, the analysis line is displayed, however, it can be hidden from view manually. In all result displays, the "AL" label in the window title bar indicates whether the analysis line lies within the analysis interval or not:
●
orange "AL": the line lies within the interval
●
white "AL": the line lies within the interval, but is not displayed (hidden)
15User Manual 1178.6327.02 ─ 06
Page 16
R&S®FSW-K118 /-K119
●
no "AL": the line lies outside the interval
For details on the MSRA operating mode, see the R&S FSW MSRA documentation.

3.4 I/Q measurements

Access: [MEAS] > "EVM/Frequency Err/Power"
You can select the result displays from the evaluation bar and arrange them as you like with the SmartGrid functionality.

I/Q measurements
Capture Buffer
The "Capture Buffer" shows the complete range of captured data for the last data cap­ture.
The x-axis represents time. The maximum value of the x-axis is equal to the Capture
Time.
The y-axis represents the amplitude of the captured I/Q data in dBm (for RF input).

Page 17
R&S®FSW-K118 /-K119
A green bar at the bottom of the diagram represents the frame that is currently ana­lyzed.
A green vertical line at the beginning of the green bar in the capture buffer represents the frame start. The diagram also contains the "Start Offset" value. This value is the time difference between the frame start and capture buffer start.

EVM vs Carrier
The "EVM vs Carrier" result display shows the error vector magnitude (EVM) of the subcarriers. With the help of a marker, you can use it as a debugging technique to identify any subcarriers whose EVM is too high.
The results are based on an average EVM that is calculated over the resource ele­ments for each subcarrier. The average subcarrier EVM is calculated over the com­plete radio frame.
The x-axis represents the center frequencies of the subcarriers. The y-axis shows the EVM in % or in dB, depending on the EVM Unit.

Remote command: Selection LAY:ADD ? '1',LEFT,EVCA Query (y-axis): TRACe:DATA? Query (x-axis): TRACe<n>[:DATA]:X? on page 108
EVM vs Symbol
The "EVM vs Symbol" result display shows the error vector magnitude (EVM) of the OFDM symbols. You can use it as a debugging technique to identify any symbols whose EVM is too high.
The results are based on an average EVM that is calculated over all subcarriers that are part of a certain OFDM symbol. The average OFDM symbol EVM is calculated over the complete radio frame.
The x-axis represents the OFDM symbols, with each symbol represented by a dot on the line. Any missing connections from one dot to another mean that the R&S FSW could not determine the EVM for that symbol.

4 Configuration

V5GTF measurements require a special application on the R&S FSW, which you acti­vate using the [MODE] key on the front panel.
When you start the V5GTF application, the R&S FSW starts to measure the input sig­nal with the default configuration or the configuration of the last measurement (when you have not performed a preset since then). After you have started an instance of the V5G application, the application displays the "Meas Config" menu which contains func­tions to define the characteristics of the signal you are measuring.

Selecting the V5GTF mode
The "Mode" selects the V5GTF link direction you are testing. FDD and TDD are duplexing methods.
●
FDD mode uses different frequencies for the uplink and the downlink.
●
TDD mode uses the same frequency for the uplink and the downlink. Note that the V5GTF standard only supports TDD mode.
Downlink (DL) and Uplink (UL) describe the transmission path.
●
Downlink is the transmission path from the base station to the user equipment. The physical layer mode for the downlink is always OFDM.
●
Uplink is the transmission path from the user equipment to the base station. The physical layer mode for the uplink is always OFDM.
The application shows the currently selected V5GTF mode (including the bandwidth) in the channel bar.

Remote command: Link direction: CONFigure[:V5G]:LDIRection on page 122
Carrier Aggregation
Carrier aggregation has been introduced in the V5GTF standard to increase the band­width. In those systems, several carriers can be used to transmit a signal.
You can configure up to 8 component carriers for measurements on contiguous and non-contiguous intra-band carrier aggregation (the carriers are in the same frequency band). Each carrier has the same bandwidth of 100 MHz.
The application provides the following capture modes.
●
"Single": Each configured component carrier is captured consecutively by an indi­vidual data capture buffer.
●
"Auto": The R&S FSW determines how many component carriers it can capture in a single measurement
If you select "Auto" mode, the R&S FSW captures as many component carriers as it can in a single measurement and captures the rest in subsequent measurements. The maximum number of component carriers it can analyze in a single capture depends on the available bandwidth (with the optional 500 MHz bandwidth, for example, it can ana­lyze up to 5 carriers in a single capture).
When all required measurements are done, the R&S FSW shows the results for all component carriers.
Configuration
Physical signal characteristics
Basic component carrier configuration ← Carrier Aggregation
You can define the characteristics of the CCs in the table in the "Carrier Configuration" panel (in the "Signal Characteristics" dialog box). Depending on the "Number of Com­ponent Carriers", the application adjusts the size of the table. Each line corresponds to a component carrier.
●
The "Center Frequency" defines the carrier frequency of the carriers.
●
Each carrier has a bandwidth of 100 MHz.
●
For all component carriers, the R&S FSW also shows the "Frequency Offset" rela­tive to the center frequency of the first carrier. If you define a different frequency offset, the application adjusts the center fre­quency accordingly.
Note that the actual measurement frequency differs from the carrier frequencies: the application calculates that frequency based on the carrier frequencies. It is somewhere in between the carrier frequencies.
The R&S FSW shows a preview of the current carrier configuration in a diagram at the bottom of the dialog.
30User Manual 1178.6327.02 ─ 06

When the defined carrier configuration is not supported by the application, a corre­sponding error message is displayed. This can be the case, for example, if the carriers occupy a bandwidth that is too large.
Features of the I/Q measurements ← Carrier Aggregation
For measurements on component carriers, results are shown for each component car­rier separately. The layout of the diagrams is adjusted like this:
Configuration
Physical signal characteristics
●
The first tab ("All") shows the results for all component carriers.

Physical settings of the signal
Physical settings describe the basic structure of the signal you are measuring. The "Channel Bandwidth" of a V5GTF signal is always 100 MHz with a normal "Cyclic
Prefix". The physical settings also show the sample rate, FFT size, the occupied bandwidth
and number of occupied subcarriers in the signal.

The dialog box also provides an overview of the current structure of the radio frame as a comma-separated list. Each character corresponds to a subframe, "S,a,a,a,a", for example means that the first subframe is a synchronization subframe, and all other subframes are subframe type a.
Selecting the "Configure" button opens the radio frame configuration tab where you can customize the radio frame structure according to your needs.
The physical layer cell ID is responsible for synchronization between network and user equipment. It identifies a particular radio cell in the V5GTF network. The cell ID is a value between 0 and 503.
For automatic detection of the cell ID, turn on the "Auto" function (downlink only). Remote command:

4.3 Test scenarios

Configuration
Test scenarios
Access: "Overview" > "Signal Description" > "Test Models"
Test scenarios are descriptions of specific V5GTF signals for standardized testing of DUTs. These test scenarios are stored in .allocation files. You can select, manage and create test scenarios in the "Test Models" dialog box.
User defined test scenarios
User defined test scenarios are custom signal descriptions for standardized measure­ments that you can save and restore as you like. To create a custom test scenario, describe a signal as required and then save it with the corresponding button. The R&S FSW stores custom scenarios in .allocation files.
If you do not need test scenarios any longer, you can also delete them. Remote command:
Save: MMEMory:STORe<n>:DEModsetting[:CC<cc>] on page 123 Restore: MMEMory:LOAD:DEModsetting[:CC<cc>] on page 123
Test scenarios for carrier aggregation
When you measure component carriers, you can describe each component carrier separately and save or restore the scenario for each carrier in the corresponding tab ("CC<x>"). Single carrier scenarios are stored in .allocation files.
For easier handling of multiple carriers, however, you can also store the descriptions of all carriers in a single file. To do so, configure all component carriers as required and save the test scenario in "All CCs" tab. Multiple carrier test scenarios are stored in .ccallocation files. The advantage of this method is, that you do not have to restore a scenario for each component carrier, but can do so in a single step.
The .ccallocation files contain the frequency information of the signal. Remote command:
Save: MMEMory:STORe<n>:DEModsetting:ALL on page 123 Restore: MMEMory:LOAD:DEModsetting:ALL on page 122

For the other subframes, the R&S FSW repeats the pattern of the subframes you have configured, including the xPDSCH allocation configuration or xPUSCH allocation con-
figuration.
Note that you can always apply a special configuration to subframes 0, 4, 15, 25, 29,
40. After you have selected the number of configurable subframes, you can define the
characteristics of each subframe in the subframe configuration table. Each row in that table shows the characteristics of one subframe.
The last column in the table ("Repeated Subframe No.") shows the number of the sub­frame which the subframe configuration is based on.
Example:
You have entered "5" in the "Configurable Subframes" field. Thus, you can edit the first 5 subframes in the table (the others are grayed out and unavailable for editing). The configuration of the first subframe (0) is fix (sync or unused). You configure the other four subframes to carry data. This would result in the following pattern:
sync - 1 - 2 - 3 - 4 This pattern is repeated in the other subframes: sync - 1 - 2 - 3 - 4 - 1 - 2 - 3 - 4 - 1 - 2 -
3 - 4 etc. (exception: subframe 25). If you configure subframe 4 to carry the ePBCH, the pattern would look like this: sync -
1 - 2 - 3 - ePBCH - 1 - 2 - 3 - 1 - 2 - 3 etc.
Configuration
Radio frame configuration
Copying subframes
If several subframes in the radio frame have the same configuration, the easiest way is to configure one subframe and "Copy" that configuration (including the allocation con­figuration) to other subframes.
When you copy a subframe, the "Copy" button indicates which subframe is in the clip­board (for example: "Paste (SF 1)". You can then apply that configuration either to a selected subframe or all subframes:
●
"Paste" applies the copied configuration to the selected subframe. A selected subframe is highlighted in blue.
●
"Paste to All" applies the copied configuration to all other subframes.

Configuration
xPDSCH configuration (downlink)
The xPDSCH (Physical Downlink Shared Channel) primarily carries all general user data. It therefore occupies most of the resource elements in a radio frame and is pres­ent in most of the subframes used for downlink transmission.
Each downlink subframe consists of one or more (user) allocations. Each allocation, in turn, can have a different size and transmission characteristics (modulation, power etc.). The subframe configuration table provides an overview of all allocations used in the corresponding subframe and allows you to configure each allocation individually. Each row in the configuration table corresponds to one allocation.
If there are any errors or conflicts between allocations in one or more subframes, the application shows the corrupt subframe in the "Conflict" column of the table. Conflicts are highlighted red if an error occurs. In addition, it shows the conflicting rows of the configuration table.
Before you start to customize the allocations of a subframe, you should define the
number of subframes you want to have in the radio frame. The application supports the
configuration of up to 50 subframes.

Precoding
The precoding scheme selects the method by which the data is mapped to antenna ports.
The following precoding schemes are supported.
●
"None" Turns off precoding.
●
"Transmit Diversity" Turns on precoding for transmit diversity (several antennas transmit a single layer data stream to reduce transmission errors).
●
"Spatial Multiplexing" Turns on precoding for spatial multiplexing (several antennas transmit different data streams to increase data rate).
For precoding schemes "Transmit Diversity" and "Spatial Multiplexing", the xPDSCH is always transmitted on two layers. If you apply no precoding, you can select the number of "Layers" on which the xPDSCH is transmitted.
For all precoding schmes (including no precoding), you can select the antenna ports on which the xPDSCH is transmitted. The antenna ports available for xPDSCH transmis­sion is fix. In case of a two layer transmission, the xPDSCH is transmitted on a combi­nation of two (predefined) antenna ports.

UE Specific Reference Signals
Each xPDSCH or xPUSCH allocation can carry reference signals specific to the user equipment: the demodulation reference signal (DMRS) and the phase noise compen­sation reference signal (PCRS).
Both reference signals are affected by the parameter "Scrambling Identity" n
scid
. This
parameter has an effect on the sequence generation of the reference signals as defined in V5G.211. The value is either 0 or 1.

DMRS configuration ← UE Specific Reference Signals
The V5G standard (V5G.211) defines two methods by which the DMRS sequence can be calculated. You can select the method with the "Sequence Generation" parameter. The sequence is either calculated with the "n_ID^DMRS" variable (a pseudo-random seed value). Or, if the higher layers provide no value for n_ID^DMRS, the sequence is generated based on the cell ID with the "n_ID^Cell". n_ID^Cell has the same value as the cell ID.
You can define the power with which the DMRS is transmitted as a value relative to xPDSCH (on the downlink) or xPUSCH (on the uplink). By default, its power is 6 dB higher than the xPDSCH or xPUSCH.
Note: The sequence generation method is always the same for both the DMRS and the PCRS. If you select "n_ID^Cell" for either, the R&S FSW automatically selects the method for the other, and vice versa.

The PCRS is a reference signal for phase noise compensation that you can transmit in a xPDSCH or xPUSCH allocation.
If the PCRS is present (turned on), you can define various properties of that reference signal.
●
The "Rel Power (to xPDSCH)" defines the power with which the PCRS is transmit­ted. The value is a power level in dB relative to the power of the xPDSCH alloca­tion it is transmitted on.
●
The "Rel Power (to xPUSCH)" defines the power with which the PCRS is transmit­ted. The value is a power level in dB relative to the power of the xPUSCH alloca­tion it is transmitted on.
●
The "Antenna Ports" selects the antenna port it is transmitted on (60 or 61, or 60 and 61). Antenna port assignment is only possible on the downlink.
●
The "Sequence Generation" selects the method by which the PCRS sequence is calculated. The standard (V5G.211) defines two methods: "n_ID^DMRS" and "n_ID^Cell". In the latter case, the value is the cell ID.
Note: The sequence generation method is always the same for both the DMRS and the PCRS. If you select "n_ID^Cell" for either, the R&S FSW automatically selects the method for the other, and vice versa.

xPBCH and BRS Configuration
The physical broadcast channel (xPBCH) carries the broadcasting message. It always shares the symbol it is transmitted in with the beam reference signal (BRS), which serves two purposes.
●
It is the demodulation reference signal for the xPBCH.
●
It contains information for the UE about which beam that the base station trans­mits.
The xPBCH and BRS are always transmitted on subframes 0 and 25. The symbol(s) you can use for the transmission of the BRS and the xPBCH is arbitrary. Select the "Configure" button to open another dialog box that allows you to assign the BRS and xPBCH to any symbol of subframe 0 and 25 ("On" = xPBCH uses the corresponding symbol, "Off" = corresponding symbol is unused.
The list in the "Reference Signal" dialog box shows which symbols are currently occu­pied by the BRS and xPBCH.

CSI Reference Signal Configuration
The channel state information (CSI) reference signal is used to estimate the properties of the signal propagation channel from the base station to the user equipment. This information is quantized and fed back to the base station.
It can be transmitted in OFDM symbol 12 (antenna ports 16 to 23) and in the last OFDM symbol 13 (antenna ports 16 to 31).
You can define the "Power" of a CSI reference signal resource element relative to the power of the BRS.
The "N_ID^CSI" parameter defines the initial (seed) value by which the reference sig­nal sequence is generated.

ePBCH DMRS Configuration
The extended physical broadcast channel (ePBCH) is a channel that carries system information for initial cell attachment and radio resource configuration. If present, it is transmitted either in subframe 4 or 29 (the complete subframe is reserved for ePBCH in that case) and is mapped to antenna port 500 or 501.
In addition to the ePBCH information, several resource elements are reserved for the ePBCH demodulation reference signal (DMRS) which is used to demodulate the ePBCH.
The ePBCH uses the transmit diversity "Precoding" scheme (several antennas transmit a single layer data stream). You can also turn off precoding ("None").

4.9 Control channel configuration (downlink)

Access: "Overview" > "Signal Description" > "Advanced Settings" > "Control Channel"
The physical downlink control channel (xPDCCH) carries scheduling assignments like the control information (DCI) required by the UE to receive and demodulate data suc­cessfully. The xPDCCH demodulation reference signal (DMRS) allows the UE to demodulate the xPDCCH successfully.
The xPDCCH is transmitted in the first or the first two OFDM symbols of a subframe. There are several resource element groups (xREG) reserved for the reference signal and the xPDCCH control information. An xREG is a group of resource elements within an OFDM symbol that indicates a specific location in that symbol. Each OFDM symbol has 16 xREGs.

xPDCCH Configuration
The xPDCCH is located either on the first or the first two OFDM symbols in a data sub-
frame. In both cases you can allocate a xPDCCH to any of the 16 xREGs in that sym-
bol: When you select the "Configure" button, the R&S FSW opens another dialog box that allows you to select the xREGs you would like to allocate the xPDCCH to ("On" = xPDCCH occupies the corresponding xREG, "Off" = xREG is unused).
You can define the "Power" of xPDCCH resource elements relative to the power of a common resource element.
As defined by the V5GTF standard, the xPDCCH uses the transmit diversity "Precod­ing" scheme (several antennas transmit a single layer data stream). You can also turn off precoding ("None").
The V5GTF standard (V5G.211) defines two methods by which the DMRS sequence can be calculated. You can select the method with the "Sequence Generation" parame­ter. The sequence is either calculated with the "n_ID^DMRS" variable (a pseudo-ran­dom seed value). Or, if the higher layers provide no value for n_ID^DMRS, the sequence is generated based on the cell ID with the "n_ID^Cell". n_ID^Cell has the same value as the cell ID.

Antenna port mapping (downlink)

4.11 Antenna port mapping (downlink)

Access: "Overview" > "Signal Description" > "Ant Port Mapping"
Antenna ports are not physical antennas, but rather are a logical concept. Each antenna port carries certain signal components (= physical channels) that should be transmitted under the same conditions. Physical channels can be transmitted on a sin­gle antenna port, or on several antenna ports. Each antenna port in turn can be map­ped to one of the physical antennas. Typically, one physical antenna combines several antenna ports. However, one specific antenna port can also be transmitted on more than one physical antenna.
The "Ant Port Mapping" dialog box allows you to map the antenna ports used by the various physical channels defined in the V5GTF standard to one or two layer configu­rations.

In spectrum analyzers, passive analog mixers are used for the first conversion of the input signal. In such mixers, the LO signal is coupled into the IF path due to its limited isolation. The coupled LO signal becomes visible at the RF frequency 0 Hz. This effect is referred to as LO feedthrough.
To avoid the LO feedthrough the spectrum analyzer provides an alternative signal path to the A/D converter, referred to as the direct path. By default, the direct path is selected automatically for RF frequencies close to zero. However, this behavior can be disabled. If "Direct Path" is set to "Off", the spectrum analyzer always uses the analog mixer path.

Defines the center frequency of the signal and thus the frequency the R&S FSW tunes to.
62User Manual 1178.6327.02 ─ 06

Frequency Stepsize ← Signal Frequency
In addition to the frequency itself, you can also define a frequency stepsize. The fre­quency stepsize defines the extent of a frequency change if you change it, for example with the rotary knob.
You can define the stepsize in two ways.

Reference Level
The reference level is the power level the analyzer expects at the RF input. Keep in mind that the power level at the RF input is the peak envelope power for signals with a high crest factor like V5GTF.
To get the best dynamic range, you have to set the reference level as low as possible. At the same time, make sure that the maximum signal level does not exceed the refer­ence level. If it does, it will overload the A/D converter, regardless of the signal power. Measurement results can deteriorate (e.g. EVM), especially for measurements with more than one active channel near the one you are trying to measure (± 6 MHz).
Note that the signal level at the A/D converter can be stronger than the level the appli­cation displays, depending on the current resolution bandwidth. This is because the resolution bandwidths are implemented digitally after the A/D converter.
The reference level is a value in dBm. Remote command:
Reference level: DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:RLEVel on page 183
Configuration
Amplitude configuration
Auto Level ← Reference Level
Automatically determines the ideal reference level. The automatic leveling process measures the signal and defines the ideal reference signal for the measured signal.
Automatic level detection also optimizes RF attenuation. Auto leveling slightly increases the measurement time, because of the extra leveling
measurement prior to each sweep. By default, the R&S FSW automatically defines the time for auto leveling, but you can also define it manually ([Auto Set] > "Auto Level Config" > "Meas Time").
The application shows the current reference level (including RF and external attenua­tion) in the channel bar.
Remote command: Automatic: [SENSe:]ADJust:LEVel on page 197 Auto level mode: [SENSe:]ADJust:CONFigure:LEVel:DURation:MODE on page 196 Auto level time: [SENSe:]ADJust:CONFigure:LEVel:DURation on page 196
Reference Level Offset ← Reference Level
The reference level offset is an arithmetic level offset. A level offset is useful if the sig­nal is attenuated or amplified before it is fed into the analyzer. All displayed power level results are shifted by this value. Note however, that the reference value ignores the level offset. Thus, it is still mandatory to define the actual power level that the analyzer has to handle as the reference level.

Attenuating the Signal
Attenuation of the signal becomes necessary if you have to reduce the power of the signal that you have applied. Power reduction is necessary, for example, to prevent an overload of the input mixer.
For a comprehensive information about signal attenuation, refer to the user manual of the R&S FSW.
The V5GTF measurement application provides several attenuation modes.
RF Attenuation ← Attenuating the Signal
Controls the RF (or mechanical) attenuator at the RF input. If you select automatic signal attenuation, the attenuation level is coupled to the refer-
ence level. If you select manual signal attenuation, you can define an arbitrary attenuation (within
the supported value range). Positive values correspond to signal attenuation and negative values correspond to
signal gain. The application shows the attenuation level (mechanical and electronic) in the channel
bar.

ence level. If you select manual signal attenuation, you can define an arbitrary attenuation (within
the supported value range). Positive values correspond to signal attenuation and negative values correspond to
signal gain. Note that the frequency range must not exceed the specification of the electronic
attenuator for it to work. The application shows the attenuation level (mechanical and electronic) in the channel

Preamplifier
If the (optional) internal preamplifier hardware is installed, a preamplifier can be activa­ted for the RF input signal.
You can use a preamplifier to analyze signals from DUTs with low output power. Note: If an optional external preamplifier is activated, the internal preamplifier is auto-
matically disabled, and vice versa. For all R&S FSW models except for R&S FSW85, the following settings are available:
Configuration
Amplitude configuration
"Off" "15 dB" "30 dB" For R&S FSW85 models, the input signal is amplified by 30 dB if the preamplifier is
activated. Remote command:
INPut<ip>:GAIN:STATe on page 185 INPut<ip>:GAIN[:VALue] on page 186
Input Coupling
The RF input of the R&S FSW can be coupled by alternating current (AC) or direct cur­rent (DC).
AC coupling blocks any DC voltage from the input signal. This is the default setting to prevent damage to the instrument. Very low frequencies in the input signal may be dis­torted.
However, some specifications require DC coupling. In this case, you must protect the instrument from damaging DC input voltages manually. For details, refer to the data sheet.
Remote command:
INPut<ip>:COUPling on page 185
Deactivates the preamplifier. The RF input signal is amplified by about 15 dB. The RF input signal is amplified by about 30 dB.
Impedance
For some measurements, the reference impedance for the measured levels of the R&S FSW can be set to 50 Ω or 75 Ω.
Select 75 Ω if the 50 Ω input impedance is transformed to a higher impedance using a 75 Ω adapter of the RAZ type. (That corresponds to 25Ω in series to the input impe­dance of the instrument.) The correction value in this case is 1.76 dB = 10 log (75Ω/ 50Ω).

Capture Time
The "Capture Time" corresponds to the time of one measurement. Therefore, it defines the amount of data the application captures during a single measurement (or sweep).
By default, the application captures 20.1 ms of data to make sure that at least one complete V5GTF frame is captured in the measurement.
The application shows the current capture time in the channel bar. Note that if you are using the multi-standard radio analyzer, only the MSRA primary
channel actually captures the data. The capture time only defines the V5GTF analysis interval.
Remote command:
[SENSe:]SWEep:TIME on page 188
Swap I/Q
Swaps the real (I branch) and the imaginary (Q branch) parts of the signal. Remote command:
[SENSe:]SWAPiq on page 188
Maximum Bandwidth
The maximum bandwidth you can use depends on your hardware configuration. (The following options are available for the choosing the maximum bandwidth:
160 MHz, 512 MHz, 1200 MHz.)
67User Manual 1178.6327.02 ─ 06
Page 68
R&S®FSW-K118 /-K119
By default, the application automatically determines the maximum bandwidth. When you select a maximum bandwidth other than "Auto", the bandwidth is restricted to that value. Otherwise, the signal may be distorted and results are no longer valid.
For more information about the maximum bandwidth, refer to the user manual of the R&S FSW I/Q Analyzer.
Remote command:
TRACe<n>:IQ:WBANd:MBWidth on page 189
Maximum Number of Subframes per Frame to Analyze
Selects the maximum number of subframes that the application analyzes and therefore improves measurement speed.
Reducing the number of analyzed subframes may become necessary if you define a capture time of less than 20.1 ms. For successful synchronization, all subframes that you want to analyze must be in the capture buffer. You can make sure that this is the case by using, for example, an external frame trigger signal.

Trigger configuration

4.16 Trigger configuration

Access: "Overview" > "Trig / Sig Capture" > "Trigger"
A trigger allows you to capture those parts of the signal that you are really interested in.
While the application runs freely and analyzes all signal data in its default state, no matter if the signal contains information or not, a trigger initiates a measurement only under certain circumstances (the trigger event).
Except for the available trigger sources, the functionality is the same as that of the R&S FSW base system.
For a comprehensive description of the available trigger settings not described here, refer to the documentation of the R&S FSW.
Trigger Source...............................................................................................................68
Trigger Source
The application supports several trigger modes or sources.
●
Free Run

68User Manual 1178.6327.02 ─ 06
Page 69
R&S®FSW-K118 /-K119
●
External <x>
The trigger event is the level of an external trigger signal. The measurement starts when this signal meets or exceeds a specified trigger level at the trigger input. Some measurement devices have several trigger ports. When you use one of these, several external trigger sources are available.
●
I/Q Power
The trigger event is the magnitude of the sampled I/Q data. The measurement starts when the magnitude of the I/Q data meets or exceeds the trigger level.
●
IF Power
The trigger event is the level of the intermediate frequency (IF). The measurement starts when the level of the IF meets or exceeds the trigger level.
●
RF Power
The trigger event is the level measured at the RF input. The measurement starts when the level of the signal meets or exceeds the trigger level.
For all trigger sources, except "Free Run", you can define several trigger characteris­tics.
●
The trigger "Level" defines the signal level that initiates the measurement.
●
The trigger "Offset" is the time that must pass between the trigger event and the start of the measurement. This can be a negative value (a pretrigger).
●
The trigger "Drop-out Time" defines the time the input signal must stay below the trigger level before triggering again.
●
The trigger "Slope" defines whether triggering occurs when the signal rises to the trigger level or falls down to it.
●
The trigger "Holdoff" defines a time period that must at least pass between one trig­ger event and the next.
●
The trigger "Hysteresis" is available for the IF power trigger. It defines a distance to the trigger level that the input signal must stay below to fulfill the trigger condition.
For a detailed description of the trigger parameters, see the user manual of the I/Q analyzer.

5.1.2 Diagram scale

Analysis
General analysis tools
Access: "Overview" > "Analysis" > "Scale"
You can change the scale of the y-axis in various diagrams. The y-axis scale deter­mines the vertical resolution of the measurement results.
The scale of the x-axis in the diagrams is fix. If you want to get a better resolution of the x-axis, you have to zoom into the diagram.
The remote commands required to configure the y-axis scale are described in Chap-
ter 6.9.1, "Y-Axis scale", on page 197.
Manual scaling of the y-axis..........................................................................................73
Automatic scaling of the y-axis......................................................................................73
Manual scaling of the y-axis
The "Y Minimum" and "Y Maximum" properties define a custom scale of the y-axis. The "Y Minimum" corresponds to the value at the origin. The "Y Maximum" corre-
sponds to the last value on the y-axis. The scale you select applies to the currently active window.
You can restore the original scale anytime with the "Restore Scale" button. Remote command:
DISPlay[:WINDow<n>][:SUBWindow<w>]:TRACe<t>:Y[:SCALe]:MAXimum

5.1.4 Markers

Access: "Overview" > "Analysis" > "Marker"
Markers are a tool that help you to identify measurement results at specific trace points. When you turn on a marker, it gives you the coordinates of its position, for example the frequency and its level value or the symbol and its EVM value.
In general, the marker functionality of setting and positioning markers is similar to the spectrum application.
For I/Q measurement, the R&S FSW supports up to four markers, for frequency sweep measurements there are more. Markers give either absolute values (normal markers) or values relative to the first marker (deltamarkers). If a result display has more than one trace, for example the "EVM vs Symbol" result display, you can position the marker on either trace. By default, all markers are positioned on trace 1.
Note that if you analyze more than one bandwidth part, each bandwidth part is repre­sented by a different trace.
The R&S FSW also supports several automatic positioning mechanisms that allow you to move the marker to the maximum trace value (peak), the minimum trace value or move it from peak to subsequent peak.
The marker table summarizes the marker characteristics.

Markers in result displays with a third quantity
In result displays that show a third quantity, for example the "EVM vs Symbol x Carrier" result, the R&S FSW provides an extended marker functionality.
You can position the marker on a specific resource element, whose position is defined by the following coordinates:
●
The "Symbol" input field selects the symbol.
●
The "Carrier" input field selects the carrier.
Alternatively, you can define the marker position in the "Marker Configuration" dialog box, which is expanded accordingly.

6.2 Introduction

Commands are program messages that a controller (e.g. a PC) sends to the instru­ment or software. They operate its functions ('setting commands' or 'events') and request information ('query commands'). Some commands can only be used in one way, others work in two ways (setting and query). If not indicated otherwise, the com­mands can be used for settings and queries.
Remote control
Introduction
Irrelevant for the V5GTF application.
The syntax of a SCPI command consists of a header and, usually, one or more param­eters. To use a command as a query, you have to append a question mark after the last header element, even if the command contains a parameter.
A header contains one or more keywords, separated by a colon. Header and parame­ters are separated by a "white space" (ASCII code 0 to 9, 11 to 32 decimal, e.g. blank). If there is more than one parameter for a command, they are separated by a comma from one another.
Only the most important characteristics that you need to know when working with SCPI commands are described here. For a more complete description, refer to the user manual of the R&S FSW.
Remote command examples
Note that some remote command examples mentioned in this general introduction are possibly not supported by this particular application.

6.2.1 Conventions used in descriptions

The following conventions are used in the remote command descriptions:
●
Command usage
If not specified otherwise, commands can be used both for setting and for querying parameters. If a command can be used for setting or querying only, or if it initiates an event, the usage is stated explicitly.
●
Parameter usage
If not specified otherwise, a parameter can be used to set a value and it is the result of a query.
79User Manual 1178.6327.02 ─ 06
Page 80
R&S®FSW-K118 /-K119
Parameters required only for setting are indicated as Setting parameters. Parameters required only to refine a query are indicated as Query parameters. Parameters that are only returned as the result of a query are indicated as Return values.
●
Conformity Commands that are taken from the SCPI standard are indicated as SCPI con­firmed. All commands used by the R&S FSW follow the SCPI syntax rules.
●
Asynchronous commands
A command which does not automatically finish executing before the next com­mand starts executing (overlapping command) is indicated as an Asynchronous command.
●
Reset values (*RST)
Default parameter values that are used directly after resetting the instrument (*RST command) are indicated as *RST values, if available.
●
Default unit
The default unit is used for numeric values if no other unit is provided with the parameter.
●
Manual operation
If the result of a remote command can also be achieved in manual operation, a link to the description is inserted.

Introduction

6.2.2 Long and short form

The keywords have a long and a short form. You can use either the long or the short form, but no other abbreviations of the keywords.
The short form is emphasized in uppercase letters. Note however, that this emphasis only serves the purpose to distinguish the short from the long form in the manual. For the instrument, the case does not matter.
Example:
SENSe:FREQuency:CENTer is the same as SENS:FREQ:CENT.

6.2.3 Numeric suffixes

Some keywords have a numeric suffix if the command can be applied to multiple instances of an object. In that case, the suffix selects a particular instance (e.g. a mea­surement window).
Numeric suffixes are indicated by angular brackets (<n>) next to the keyword.
If you do not quote a suffix for keywords that support one, a 1 is assumed.
80User Manual 1178.6327.02 ─ 06
Page 81
R&S®FSW-K118 /-K119
Example:
DISPlay[:WINDow<1...4>]:ZOOM:STATe enables the zoom in a particular mea­surement window, selected by the suffix at WINDow.
DISPlay:WINDow4:ZOOM:STATe ON refers to window 4.

6.2.4 Optional keywords

Some keywords are optional and are only part of the syntax because of SCPI compli­ance. You can include them in the header or not.
If an optional keyword has a numeric suffix and you need to use the suffix, you have to include the optional keyword. Otherwise, the suffix of the missing keyword is assumed to be the value 1.
Optional keywords are emphasized with square brackets.
Example:
Without a numeric suffix in the optional keyword: [SENSe:]FREQuency:CENTer is the same as FREQuency:CENTer With a numeric suffix in the optional keyword:
DISPlay[:WINDow<1...4>]:ZOOM:STATe DISPlay:ZOOM:STATe ON enables the zoom in window 1 (no suffix). DISPlay:WINDow4:ZOOM:STATe ON enables the zoom in window 4.
Remote control
Introduction

6.2.5 Alternative keywords

A vertical stroke indicates alternatives for a specific keyword. You can use both key­words to the same effect.
Example:
[SENSe:]BANDwidth|BWIDth[:RESolution]
In the short form without optional keywords, BAND 1MHZ would have the same effect as BWID 1MHZ.

6.2.6 SCPI parameters

Many commands feature one or more parameters.
If a command supports more than one parameter, they are separated by a comma.
Example:
LAYout:ADD:WINDow Spectrum,LEFT,MTABle

● Block data............................................................................................................... 83
6.2.6.1 Numeric values
Numeric values can be entered in any form, i.e. with sign, decimal point or exponent. For physical quantities, you can also add the unit. If the unit is missing, the command uses the basic unit.
Example:
With unit: SENSe:FREQuency:CENTer 1GHZ Without unit: SENSe:FREQuency:CENTer 1E9 would also set a frequency of 1 GHz.
Remote control
Introduction
Values exceeding the resolution of the instrument are rounded up or down.
If the number you have entered is not supported (e.g. for discrete steps), the command returns an error.
Instead of a number, you can also set numeric values with a text parameter in special cases.
●
MIN/MAX Defines the minimum or maximum numeric value that is supported.
●
DEF Defines the default value.
●
UP/DOWN Increases or decreases the numeric value by one step. The step size depends on the setting. Sometimes, you can customize the step size with a corresponding command.
Querying numeric values
When you query numeric values, the system returns a number. For physical quantities, it applies the basic unit (e.g. Hz for frequencies). The number of digits after the decimal point depends on the type of numeric value.
Example:
Setting: SENSe:FREQuency:CENTer 1GHZ Query: SENSe:FREQuency:CENTer? would return 1E9
Sometimes, numeric values are returned as text.
●
INF/NINF Infinity or negative infinity. Represents the numeric values 9.9E37 or -9.9E37.
●
NAN
82User Manual 1178.6327.02 ─ 06
Page 83
R&S®FSW-K118 /-K119
Not a number. Represents the numeric value 9.91E37. NAN is returned if errors occur.
6.2.6.2 Boolean
Boolean parameters represent two states. The "on" state (logically true) is represented by "ON" or the numeric value 1. The "off" state (logically untrue) is represented by "OFF" or the numeric value 0.
Querying Boolean parameters
When you query Boolean parameters, the system returns either the value 1 ("ON") or the value 0 ("OFF").
Example:
Setting: DISPlay:WINDow:ZOOM:STATe ON Query: DISPlay:WINDow:ZOOM:STATe? would return 1
Remote control
Introduction
6.2.6.3 Character data
Character data follows the syntactic rules of keywords. You can enter text using a short or a long form. For more information, see Chapter 6.2.2, "Long and short form", on page 80.
Querying text parameters
When you query text parameters, the system returns its short form.
Example:
Setting: SENSe:BANDwidth:RESolution:TYPE NORMal Query: SENSe:BANDwidth:RESolution:TYPE? would return NORM
6.2.6.4 Character strings
Strings are alphanumeric characters. They have to be in straight quotation marks. You can use a single quotation mark ( ' ) or a double quotation mark ( " ).
Example:
INSTRument:DELete 'Spectrum'
6.2.6.5 Block data
Block data is a format which is suitable for the transmission of large amounts of data.
The ASCII character # introduces the data block. The next number indicates how many of the following digits describe the length of the data block. The data bytes follow. Dur­ing the transmission of these data bytes, all end or other control signs are ignored until
83User Manual 1178.6327.02 ─ 06
Page 84
R&S®FSW-K118 /-K119
all bytes are transmitted. #0 specifies a data block of indefinite length. The use of the indefinite format requires an NL^END message to terminate the data block. This format is useful when the length of the transmission is not known or if speed or other consid­erations prevent segmentation of the data into blocks of definite length.

This command duplicates the currently selected channel, i.e creates a new channel of the same type and with the identical measurement settings. The name of the new channel is the same as the copied channel, extended by a consecutive number (e.g. "IQAnalyzer" -> "IQAnalyzer 2").
The channel to be duplicated must be selected first using the INST:SEL command.
Example:
INST:SEL 'IQAnalyzer' INST:CRE:DUPL
Duplicates the channel named 'IQAnalyzer' and creates a new channel named 'IQAnalyzer2'.
Usage: Event
INSTrument:CREate[:NEW] <ChannelType>, <ChannelName>
This command adds an additional measurement channel. You can configure up to 10 measurement channels at the same time (depending on available memory).
Parameters:
<ChannelType> Channel type of the new channel.
For a list of available channel types see INSTrument:LIST? on page 85.
<ChannelName> String containing the name of the channel.

<Position> New vertical or horizontal position of the splitter as a fraction of
the screen area (without channel and status bar and softkey menu). The point of origin (x = 0, y = 0) is in the lower left corner of the screen. The end point (x = 100, y = 100) is in the upper right cor­ner of the screen. (See Figure 6-1.) The direction in which the splitter is moved depends on the screen layout. If the windows are positioned horizontally, the splitter also moves horizontally. If the windows are positioned vertically, the splitter also moves vertically.

ABORt
This command aborts the measurement in the current channel and resets the trigger system.
To prevent overlapping execution of the subsequent command before the measure­ment has been aborted successfully, use the *OPC? or *WAI command after ABOR and before the next command.
For details on overlapping execution see Remote control via SCPI.
Note on blocked remote control programs:
If a sequential command cannot be completed, for example because a triggered sweep never receives a trigger, the remote control program will never finish and the remote channel to the R&S FSW is blocked for further commands. In this case, you must inter­rupt processing on the remote channel first in order to abort the measurement.

To do so, send a "Device Clear" command from the control instrument to the R&S FSW on a parallel channel to clear all currently active remote channels. Depending on the used interface and protocol, send the following commands:
●
Visa: viClear()
●
GPIB: ibclr()
●
RSIB: RSDLLibclr()
Now you can send the ABORt command on the remote channel performing the mea­surement.

Example:
Usage: Event
INITiate<n>:CONTinuous <State>
This command controls the measurement mode for an individual channel.
Note that in single measurement mode, you can synchronize to the end of the mea­surement with *OPC, *OPC? or *WAI. In continuous measurement mode, synchroniza­tion to the end of the measurement is not possible. Thus, it is not recommended that you use continuous measurement mode in remote control, as results like trace data or markers are only valid after a single measurement end synchronization.
For details on synchronization see Remote control via SCPI.
Suffix:

Example:
INITiate:SEQuencer:MODE <Mode>
Defines the capture mode for the entire measurement sequence and all measurement groups and channels it contains.
Note: In order to synchronize to the end of a measurement sequence using *OPC, *OPC? or *WAI you must use SINGle Sequence mode.
Parameters: <Mode> SINGle
SYST:SEQ ON
Activates the Sequencer.
INIT:SEQ:MODE SING
Sets single sequence mode so each active measurement will be performed once.
INIT:SEQ:IMM
Starts the sequential measurements.
Each measurement group is started one after the other in the order of definition. All measurement channels in a group are started simultaneously and performed once. After all measure­ments are completed, the next group is started. After the last group, the measurement sequence is finished.
CONTinuous
Each measurement group is started one after the other in the order of definition. All measurement channels in a group are started simultaneously and performed once. After all measure­ments are completed, the next group is started. After the last group, the measurement sequence restarts with the first one and continues until it is stopped explicitely.
*RST:
CONTinuous
SYSTem:SEQuencer <State>
This command turns the Sequencer on and off. The Sequencer must be active before any other Sequencer commands (INIT:SEQ...) are executed, otherwise an error will occur.
Parameters:
<State> ON | OFF | 0 | 1
ON | 1
The Sequencer is activated and a sequential measurement is started immediately.
OFF | 0
The Sequencer is deactivated. Any running sequential measure­ments are stopped. Further Sequencer commands (INIT:SEQ...) are not available.

6.6 Remote commands to retrieve trace data

● Using the TRACe[:DATA] command..................................................................... 100

6.6.1 Using the TRACe[:DATA] command

This chapter contains information on the TRACe:DATA command and a detailed description of the characteristics of that command.
The TRACe:DATA command queries the trace data or results of the currently active measurement or result display. The type, number and structure of the return values are specific for each result display. In case of results that have any kind of unit, the com­mand returns the results in the unit you have currently set for that result display.
For several result displays, the command also supports various SCPI parameters in combination with the query. If available, each SCPI parameter returns a different aspect of the results. If SCPI parameters are supported, you have to quote one in the query.
Example:
TRAC2:DATA? TRACE1
The format of the return values is either in ASCII or binary characters and depends on the format you have set with FORMat[:DATA].
Following this detailed description, you will find a short summary of the most important functions of the command (TRACe<n>[:DATA]?).
Selecting a measurement window
Before querying results, you have to select the measurement window with the suffix <n> at TRACe. The range of <n> depends on the number of active measurement win­dows.
For measurements on aggregated carriers, where each measurement window has subwindows, you have to select the subwindow first with DISPlay[:WINDow<n>][:
SUBWindow<w>]:SELect.
