The R&S ESW is equipped with a network interface and can be connected to an Ether­net LAN (local area network). Provided the network administrator has assigned you the appropriate rights and adapted the Windows firewall configuration, you can use the interface, for example:
To transfer data between a controlling device and the test device, e.g. to run a remote control program. See chapter "Remote Control".
To access or control the measurement from a remote computer using the "Remote Desktop" application (or a similar tool)
To connect external network devices (e.g. printers)
To transfer data from a remote computer and back, e.g. using network folders

4.5.1 Connecting the Instrument to the Network

Preparing for Use
Setting Up a Network (LAN) Connection
This section describes how to configure the LAN interface. It includes the following top­ics:
Chapter 4.5.1, "Connecting the Instrument to the Network", on page 35
Chapter 4.5.2, "Assigning the IP Address", on page 36
Note that only user accounts with administrator rights can configure LAN networks.
LXI
The R&S ESW supports the LXI core features. LXI gives you direct access to the LAN settings described below.
For further information on the LXI interface, refer to Chapter 14.4.4, "LXI Settings", on page 405.
There are two methods to establish a LAN connection to the instrument:
A non-dedicated network (Ethernet) connection from the instrument to an existing network made with an ordinary RJ-45 network cable. The instrument is assigned an IP address and can coexist with a computer and with other hosts on the same network.
A dedicated network connection (Point-to-point connection) between the instru­ment and a single computer made with a (crossover) RJ-45 network cable. The computer must be equipped with a network adapter and is directly connected to the instrument. The use of hubs, switches, or gateways is not required, however, data transfer is still performed using the TCP/IP protocol. You must assign an IP address to the instrument and the computer, see Chapter 4.5.2, "Assigning the IP
Address", on page 36.
Note: As the R&S ESW uses a 1 GBit LAN, a crossover cable is not necessary (due to Auto-MDI(X) functionality).
Risk of network failure
Consult your network administrator before performing the following tasks:
Connecting the instrument to the network
Configuring the network
Changing IP addresses
Exchanging hardware
Errors can affect the entire network.
► To establish a non-dedicated network connection, connect a commercial RJ-45
cable to one of the LAN ports.

4.5.2 Assigning the IP Address

Preparing for Use
Setting Up a Network (LAN) Connection
To establish a dedicated connection, connect a (crossover) RJ-45 cable between the instrument and a single PC.
If the instrument is connected to the LAN, Windows automatically detects the network connection and activates the required drivers.
The network card can be operated with a 1 GBit Ethernet IEEE 802.3u interface.
Depending on the network capacities, the TCP/IP address information for the instru­ment can be obtained in different ways.
If the network supports dynamic TCP/IP configuration using the Dynamic Host Configuration Protocol (DHCP), all address information can be assigned automati­cally.
If the network does not support DHCP, or if the instrument is set to use alternate TCP/IP configuration, the addresses must be set manually.
By default, the instrument is configured to use dynamic TCP/IP configuration and obtain all address information automatically. This means that it is safe to establish a physical connection to the LAN without any previous instrument configuration.
Risk of network errors
Connection errors can affect the entire network. If your network does not support DHCP, or if you choose to disable dynamic TCP/IP configuration, you must assign valid address information before connecting the instrument to the LAN. Contact your net­work administrator to obtain a valid IP address.
Assigning the IP address on the instrument
1. Press the [SETUP] key.
2. Press the "Network + Remote" softkey.
3. Select the "Network" tab.
4. In the "Network + Remote" dialog, toggle the "DHCP On/Off" setting to the required
mode. If DHCP is "Off", you must enter the IP address manually, as described in the fol­lowing steps. Note: When DHCP is changed from "On" to "Off", the previously set IP address and subnet mask are retrieved. If DHCP is "On", the IP address of the DHCP server is obtained automatically. The configuration is saved, and you are prompted to restart the instrument. You can skip the remaining steps. Note: When a DHCP server is used, a new IP address may be assigned each time the instrument is restarted. This address must first be determined on the instrument

itself. Thus, when using a DHCP server, it is recommended that you use the per­manent computer name, which determines the address via the DNS server (See "Using a DNS server to determine the IP address" on page 37 and Chap-
ter 4.5.3, "Using Computer Names", on page 38).
5. Enter the "IP Address", for example 192.0.2.0. The IP address consists of four
number blocks separated by dots. Every block contains a maximum of 3 numbers.
6. Enter the "Subnet Mask", for example 255.255.255.0. The subnet mask consists of
four number blocks separated by dots. Every block contains a maximum of 3 num­bers.
7. Select "Configure Network".
If you have entered an invalid IP address or subnet mask, the message "out of range" is displayed in the status line. If the settings are correct, the configuration is saved, and you are prompted to restart the instrument.
8. Confirm the displayed message ("Yes" button) to restart the instrument.
Using a DNS server to determine the IP address
If a DNS server is configured on the R&S ESW, the server can determine the current IP address for the connection using the permanent computer name.
1. Obtain the name of your DNS domain and the IP addresses of the DNS and WINS
servers on your network.
2. Press the "Windows" key on the external keyboard or the [CTRL + ESC] key com-
bination on your keyboard to access the operating system.
3. Select "Start > Settings > Network & Internet > Ethernet > Network and Sharing
Center > Connections: Ethernet".
4. In the "Ethernet Status" dialog box, select the "Properties" button.

7. On the "General" tab, select "Use the following DNS server addresses" and enter
your own DNS addresses.
For more information, refer to the Windows operating system help.

4.5.3 Using Computer Names

In a LAN that uses a DNS server (Domain Name System server), each PC or instru­ment connected in the LAN can be accessed via an unambiguous computer name instead of the IP address. The DNS server translates the host name to the IP address. This is especially useful when a DHCP server is used, as a new IP address may be assigned each time the instrument is restarted.

Page 39
R&S®ESW
Preparing for Use
Setting the Date and Time
Each instrument is delivered with an assigned computer name, but this name can be changed.
The default instrument name is a non-case-sensitive string with the following syntax:
<Type><variant>-<serial_number>
The serial number can be found on the rear panel of the instrument. It is the third part of the device ID printed on the bar code sticker:
For example, ESW26-123456
To change the computer name
1. Press the [Setup] key and then the "Network + Remote" softkey.
The current "Computer Name" is displayed in the "Network" tab.
2. Enter the new computer name.
3. Close the dialog box.

4.5.4 Changing the Windows Firewall Settings

A firewall protects an instrument by preventing unauthorized users from gaining access to it through a network. Rohde & Schwarz highly recommends the use of the firewall on your instrument. Rohde & Schwarz instruments are shipped with the Windows firewall enabled and preconfigured in such a way that all ports and connections for remote control are enabled.
For more details on firewall configuration, see the following Rohde & Schwarz White Paper:
1EF96: Malware Protection Windows 10
Note that changing firewall settings requires administrator rights.

4.6 Setting the Date and Time

Users with administrator rights can set the date and time for the internal real time clock as follows:
Opening the Date and Time Properties dialog box
1. Press the [SETUP] key.
2. Press the "Display" softkey.

5. If necessary, toggle the "Date and Time Format" between German (DE) and US.
After you have made a change and closed the dialog box, the new date and time is also adopted by the instrument.

4.7 Protecting Data Using the Secure User Mode

During normal operation, the R&S ESW uses a solid-state drive to store its operating system, instrument firmware, instrument self-alignment data, and any user data cre­ated during operation. If necessary, the solid-state drive can be removed from the R&S ESW and locked in a secure place to protect any classified data it may contain.
Redirecting storage to volatile memory
Alternatively, to avoid storing any sensitive data on the R&S ESW permanently, the secure user mode was introduced (option R&S ESW-K33). In secure user mode the instrument’s solid-state drive is write-protected so that no information can be written to memory permanently. Data that the R&S ESW normally stores on the solid-state drive is redirected to volatile memory instead, which remains available only until the instru­ment is switched off. This data includes:
Windows operating system files
Firmware shutdown files containing information on last instrument state
Self-alignment data
General instrument settings such as the IP address
Measurement settings
User data created during operation (see also Table 12-1)
Any data created by other applications installed on the R&S ESW, for example text editors (Notepad), the Clipboard, drawing tools, etc.
Users can access data that is stored in volatile memory just as in normal operation. However, when the instrument’s power is switched off, all data in this memory is cleared. Thus, in secure user mode, the instrument always starts in a defined, fixed state when switched on.
To store data such as measurement results permanently, it must be stored to an exter­nal storage device, such as a memory stick.
Limited storage space
The volatile memory used to store data in secure user mode is restricted to 256 MB. Thus, a "Memory full" error can occur although the hard disk indicates that storage space is still available.
40User Manual 1177.6298.02 ─ 08
Page 41
R&S®ESW
Preparing for Use
Protecting Data Using the Secure User Mode
Storing required data permanently
Any data that is to be available for subsequent sessions with the R&S ESW must be stored on the instrument permanently, before activating the secure user mode. This includes predefined instrument settings, transducer factors and self-alignment data.
Self-alignment data
Note that self-alignment data becomes invalid with time and due to temperature changes. Therefore, to achieve optimal accuracy, it may be preferable to perform a new self-alignment at the start of each new session on the R&S ESW.
Restricted operation
Since permanent storage is not possible, the following functions are not available in secure user mode:
Firmware update
Activating a new option key
Furthermore, since the "SecureUser" used in secure user mode does not have admin­istrator rights, administrative tasks such as LAN configuration and some general instrument settings are not available. Refer to the description of the basic instrument setup ([SETUP] menu) to find out which functions are affected.
Activating and deactivating secure user mode
Only a user with administrator rights can activate the secure user mode. Once activa­ted, a restart is required. The special user "SecureUser" is then logged on to the R&S ESW automatically using the automatic login function. While the secure user mode is active, a message is displayed in the status bar at the bottom of the screen.
Secure Passwords
By default, the initial password for both the administrator account ("Instrument") and the "SecureUser" account is "894129". When the secure user mode is activated the first time after installation, you are prompted to change the passwords for all user accounts to improve system security. Although it is possible to continue without chang­ing the passwords, it is strongly recommended that you do so.
You can change the password in Microsoft Windows for any user at any time via: "Start > Settings > Account > SignIn Options > Password > Change"
To deactivate the secure user mode, the "SecureUser" must log off and the "Instru­ment" user (administrator) must log on.
Switching users when using the automatic login function
In the "Start" menu, select the arrow next to the "Shut down" button and then "Log off". The "Login" dialog box is displayed, in which you can enter the different user account
name and password.

Preparing for Use
Protecting Data Using the Secure User Mode
The secure user mode setting and automatic login is automatically deactivated when the "Instrument" user logs on. The "SecureUser" is no longer available.
For administrators ("Instrument" user), the secure user mode setting is available in the general system configuration settings (see "SecureUser Mode" on page 340).
Remote control
Initially after installation of the R&S ESW-K33 option, secure user mode must be enabled manually once before remote control is possible.
(See SYSTem:SECurity[:STATe].)
This is necessary to prompt for a change of passwords.

5.1.8 RF Inputs (50 Ω)

Instrument Tour
The Front Panel
The R&S ESW provides two RF inputs for connection of a device under test (DUT) to the R&S ESW. The DUT is connected to the RF Input via cable and an approriate con­nector (for example a male N connector).
The first RF Input supports a frequency range from 2 Hz to f range from 0 dB to 75 dB. The second RF Input supports a frequency range from 2 Hz
to 1 GHz and an attenuation range from 10 dB to 75 dB. Attenuation levels greater than 10 dB at RF Input 2 are only possible when the pulse limiter is not active (refer to the User Manual for more information).
Risk of instrument damage
Do not overload the RF input. For maximum allowed values, see the data sheet. For AC-coupling, a DC input voltage of 50 V must never be exceeded. For DC-cou-
pling, DC voltage must not be applied at the input. In both cases, noncompliance will destroy the input mixers.
When measuring unknown signals, do not use a 0 dB attenuation level. Otherwise, the input mixer may be damaged or destroyed.
When measuring unknown signals on the second RF input, turn on the pulse limiter feature. Otherwise, the input mixer may be damaged or destroyed in case of high power signals.

5.1.9 Trigger Input and Output

and an attenuation
max
The female BNC connector labeled "Trigger Input" allows you to receive an external trigger signal.
The female BNC connector labeled "Trigger Input / Output" allows you to receive an external trigger signal or send a trigger signal to another device.
When you are using the connector as a trigger input, you can apply voltages in the range from 0.5 V to 3.5 V (the default value is 1.4 V). The typical input impedance is 10 kΩ.
When you are using the connector as a trigger output, the TTL compatible signal is transmitted (0 V / 5 V).
Note that you can find another connector for trigger input and output on the rear panel.
For more information about controlling and configuring trigger input and output, refer to the User Manual.

5.1.10 Navigation Control

Navigation control consists of a rotary knob and cursor keys. These keys allow you to navigate within the display or within dialog boxes.

R&S®ESW
Instrument Tour
The Front Panel
In addition to the rotary knob and the cursor keys, the navigation control also provides undo / redo functionality.
Rotary knob
The rotary knob allows you to do several things:
It increases or decreases any kind of numeric value. In most cases, the rotary knob changes numeric values with a fixed step size. Turning it to the right corresponds to an increase, turning it to the left to a decrease of a numeric value.
It works like a cursor key in dialog boxes or lists (for example dropdown menus). In that case you can navigate to one of the items with the rotary knob. If the dialog box covers more than one screen page, it also scrolls through the dialog box. Turning it to the right corresponds to a downward movement. Moving it to the left to an upward movement.
It moves around markers and other graphical elements on the screen. In most cases, the step size is fix.
Pressing the rotary knob has the same effect as pressing the [ENTER] key as it confirms an entry or selection.
Cursor keys
The cursor keys allow you to do several things:
The up and down keys increase or decrease any kind of numeric value if an input field is active. The cursor keys change numeric values with a fixed step size.
The cursor keys navigate through dialog boxes or lists (for example dropdown menus).
The left and right keys move the cursor in an input field in the corresponding direc­tion.
The up and down keys move markers around. The step size is fix.
The cursor keys allow you to navigate to a cell in a table.
The cursor keys move a scroll bar (vertical or horizontal) in dialog boxes that have one.
Undo and redo functionality
Reverts the software to an older state by erasing the last change you have applied. The undo function is useful, for example, if you are performing a measurement with
several markers and a limit line and accidentally select a different measurement. In this case, a lot of settings would be lost. However, if you press [UNDO] immediately afterwards, the previous status is retrieved.
Reverses an undo action or repeats the most recently performed action.

When you activate an application, a new measurement channel is created which deter­mines the measurement settings for that application. The same application can be acti­vated with different measurement settings by creating several channels for the same application. Whenever you switch channels, the corresponding measurement settings are restored. Each channel is displayed in a separate tab on the screen.
An additional tab ("MultiView") provides an overview of all currently active channels at once.
Only one measurement can be performed at any time, namely the one in the currently active channel. However, in order to perform the configured measurements consecu­tively, a Sequencer function is provided.

Measurement results can be evaluated in many different ways, for example graphically, as summary tables, statistical evaluations etc. Each type of evaluation is displayed in a separate window in the channel tab. Up to 16 individual windows can be displayed per channel (i.e. per tab). To arrange the diagrams and tables on the screen, the Rohde & Schwarz SmartGrid function helps you find the target position simply and quickly.
Principally, the layout of the windows on the screen is based on an underlying grid, the SmartGrid. However, the SmartGrid is dynamic and flexible, allowing for many different layout possibilities. The SmartGrid functionality provides the following basic features:
Windows can be arranged in columns or in rows, or in a combination of both.
Windows can be arranged in up to four rows and four columns.
Windows are moved simply by dragging them to a new position on the screen, pos­sibly changing the layout of the other windows, as well.
All evaluation methods available for the currently selected measurement are dis­played as icons in the evaluation bar. If the evaluation bar contains more icons than can be displayed at once on the screen, it can be scrolled vertically. The same evaluation method can be displayed in multiple windows simultaneously.
New windows are added by dragging an evaluation icon from the evaluation bar to the screen. The position of each new window depends on where you drop the eval­uation icon in relation to the existing windows.
All display configuration actions are only possible in SmartGrid mode. When Smart­Grid mode is activated, the evaluation bar replaces the current softkey menu dis­play. When the SmartGrid mode is deactivated again, the previous softkey menu display is restored.

Operating the Instrument
Displaying Results
SmartGrid display
During any positioning action, the underlying SmartGrid is displayed. Different colors and frames indicate the possible new positions. The position in the SmartGrid where you drop the window determines its position on the screen.
Figure 6-1: Moving a window in SmartGrid mode
The brown area indicates the possible "drop area" for the window, i.e. the area in which the window can be placed. A blue area indicates the (approximate) layout of the win­dow as it would be if the icon were dropped at the current position. The frames indicate the possible destinations of the new window with respect to the existing windows: above/below, right/left or replacement (as illustrated in Figure 6-2). If an existing win­dow would be replaced, the drop area is highlighted in a darker color shade.
Positioning the window
The screen can be divided into up to four rows. Each row can be split into up to four columns, where each row can have a different number of columns. However, rows always span the entire width of the screen and may not be interrupted by a column. A single row is available as the drop area for the window in the SmartGrid. The row can be split into columns, or a new row can be inserted above or below the existing row (if the maximum of 4 has not yet been reached).

Applications
R&S MultiView

8 Applications

The R&S ESW provides several applications for different analysis tasks (for example the Receiver application or the I/Q Analyzer). When you activate an application, the R&S ESW creates a new measurement channel which in turn determines the mea­surement settings for that application. You can use the same application with different measurement settings by creating several channels for the same application. Each channel is represented by a separate tab on the screen.
Note that the number of channels may be limited by the available memory of the R&S ESW.
Switching between applications
When you enter another application for the first time, a set of selected parameters is passed on from the current application to the other one, for example the measurement frequency or the attenuation. Thus, you can switch between applications quickly and easily.
You can also define a fix set of parameters that are synchronized between applica­tions. For more information see Chapter 13.7, "Synchronizing Measurement Channel
Configuration", on page 347.

Performing continuous measurements
When you measure continuously, the measurement is repeated until you deliberately stop it.
The duration of each individual measurement cycle (for example a single bargraph measurement) depends on the measurement time you have set for the measurement in question. After each measurement cycle, the data of the previous cycle is overwrit­ten and replaced by the new data. Exception: When you are using a max or min hold function, the application keeps the highest or lowest values and replaces old data only if the current data contains a new maximum or minimum.
The R&S ESW allows you to select the measurement mode for the bargraph and the scan separately. When you select a continuous bargraph measurement, IF analysis (including the spectrogram) is also performed continuously. When you select a continu­ous scan, the scan spectrogram is also updated continuously. Running a continuous final measurement is not possible.
To start a continuous scan, press either the [RUN CONT] key on the front panel or the "Continuous Scan" softkey in the "Sweep" menu.
To start a continuous bargraph measurement, press the "Continuous Bargraph" soft­key in the "Sweep" menu.

Note: Pressing the [RUN CONT] key again interrupts the scan (see Chapter 9.3.3.2,
"Interrupting a Scan", on page 115) and does not stop it.
Continuous measurements are the default measurement mode. Remote command:
Selection: INITiate<n>:CONTinuous on page 441 Initialization: INITiate<mt>[:IMMediate] on page 442
Performing single measurements
When you run a single measurement, the measurement is performed once and then stopped. The duration of the measurement depends on the measurement time.
Note that a single measurement does not necessarily consist of a single measurement. A single measurement can consist of several measurements, whose number you can define with the Scan Count. In that case, the measurement stops when all measure­ments defined by the scan count or bargraph count are done.
The R&S ESW allows you to select the measurement mode for the bargraph and the scan separately. When you select a single bargraph measurement, IF analysis also stops when the bargraph measurement stops. Note, however, that the time defined for a single bargraph measurement can result in more than one update of the IF analysis trace (including the IF spectrogram). When you select a single scan, the spectrogram update also stops when the scan stops, but it can consist of several new lines in the spectrogram, depending on the configuration.
To start a single scan, press either the [RUN SINGLE] key on the front panel or the "Single Scan" softkey in the "Sweep" menu.
To start a single bargraph measurement, press the "Single Bargraph" softkey in the "Sweep" menu.
Note: Pressing the [RUN SINGLE] key again interrupts the scan (see Chapter 9.3.3.2,
"Interrupting a Scan", on page 115) and does not stop it.
Note on performing continuous sequenced measurements: When you are using the sequencer, you can select the measurement mode for each
measurement channel that is part of the sequence. Thus, the "Single Scan" and "Single Bargraph" softkeys only control the measurement
mode for the currently selected measurement channel (for a channel defined sequence). In addition, the [RUN SINGLE] key in that case controls the sequencer, not a particular channel.
Remote command: Selection: INITiate<n>:CONTinuous on page 441 Single scan or bargraph: INITiate<mt>[:IMMediate] on page 442 Single final measurement: INITiate<mt>:FMEasurement on page 442 Single test sequence: INITiate<mt>:EMITest on page 442
Performing sequenced measurements
When you run a sequenced measurement, you can combine measurements of several applications into a sequence of measurements. This sequence of measurements is either performed once (single sequence), indefinitely (continuous sequence) or a mix­ture of both (channel defined sequence).

For more information regarding the general functionality of the sequencer, see Chap-
ter 8.4, "Running a Sequence of Measurements", on page 90.
In the receiver application, you can select whether to:
Run a bargraph measurement each time the receiver application has its turn.
Run a scan each time the receiver application has its turn.
Skip measurements in the receiver application.
When you include the bargraph measurement in the sequence, IF analysis (including the spectrogram) is also done. When you include the scan in the sequence, spectro­gram data is also collected (and a peak search and a final measurement are performed when you have defined a test sequence that covers these measurements).
Note the following effects of performing a scan in a sequence of measurements.
Stopping a scan or final measurement aborts that measurement and resumes the measurement sequence in the next channel.
Interrupting a scan is not possible.
Interactive final measurements are not available.
Tip: Performing a continuous sequence with a single (bargraph or scan) measurement resets max hold values every time the sequencer starts a measurement in that receiver channel. To keep max hold values, use continuous measurements in the channel.
To select the measurement to include in a sequence, select [SWEEP] > "Sequencer" until the required measurement is highlighted blue.
If you want to include a bargraph measurement and a scan in the sequence of mea­surements, you have to use two measurement channels.
Remote command: See Chapter 15.5.2, "Measurement Sequences", on page 443.

9.2 Bargraph Configuration

Access: [MEAS CONFIG] > "Bargraph Config"
Alternatively, you can access the dialog box by clicking on the bargraph once.
The bargraph result display is designed for measurements on a single frequency. It is a basic result display that shows the signal level at a particular frequency numerically and graphically as a bargraph. The length of the bar depends on the signal level at the current receiver frequency. If necessary, you can control the way the signal is evalu­ated by selecting different detectors.

Measurements and Result Displays
Bargraph Configuration
1 = detectors 3 = measured levels (numerically) 4 = measured levels (graphically)
The results in the bargraph are shown as soon as you enter the receiver application (for the frequency that is currently selected) and are updated continuously. The unit of the displayed power level is variable and depends on the unit you have set (by default, it is dBµV).
The bargraph range is always 100 dB, the minimum and maximum levels that are dis­played are automatically adjusted, depending on the measurement configuration. When auto ranging has been turned off, the range depends on settings like the attenu­ation or gain. When auto ranging has been turned on, the range is adjusted to the sig­nal level.
The R&S ESW supports the simultaneous use of up to four different detectors in the bargraph result display. If you select an additional detector, the R&S ESW adds the corresponding number of bargraphs to the result display. This way to display the signal levels provides an easy way to compare the signal level with different weighting fac­tors.
Meaning of small vertical lines in the bargraph
Depending on the configuration, the following small vertical lines can appear in the bar­graph.
A small vertical line with the same color as the bargraph shows the highest value that has been measured on the currently selected frequency.
A small red vertical line with an "SQ" label shows the squelch level that you have defined for audio output over headphones.
Max hold bargraph
The max hold bargraph information, when it has been turned on, shows the highest signal level that has been measured since the measurement has begun. The max hold value remains effective, even if you change any receiver settings (for example the fre­quency or the attenuation) and is only reset when you deliberately do so. One max hold value is displayed for each of the active detectors.
When you turn on the max hold information, the diagram information is expanded by the peak level that has been measured since the max hold has been last reset (as a numerical value and including the frequency that value has been measured on). If a new peak level has been detected, the max hold values are updated accordingly.
The live results and the highest signal level for a particular frequency are still shown in the bargraph diagram as usual.

Bargraph configuration
When you are performing a scan that is not based on a scan table, the R&S ESW applies the bargraph settings (detector, measurement time etc.) to the scan.
The remote commands required to configure the bargraph are described in Chap-
ter 15.5.4, "Bargraph Configuration", on page 450.

Couple to Scan Trace
Couples or decouples the bargraph detector and scan detectors. Turning on the feature has the following effects.
Turns on a scan detector for every active bargraph. If you add a new bargraph detector, the corresponding scan trace is automatically turned on.
Matches the scan trace number to the number of the bargraph.
If you couple bargraph and scan trace, the R&S ESW replaces the detectors of all other active scan traces with the new detector type.

DISPlay:BARGraph:TCOupling[:STATe] on page 451
Bargraph Max Hold
Turns the display of the highest level that has been measured on any frequency since the last "Max Hold Reset" on and off, regardless of the receiver settings.
When you turn on the max hold information, the R&S ESW shows the highest level that has been measured for each active bargraph (detector), including the frequency where it was measured.
Note: The little vertical line displayed in the bargraph does not represent the max hold value. Instead it shows the highest level that has been measured for the current receiver frequency.
You can reset the max hold bargraph with the "Reset Max Hold" button. After you have reset the max hold bargraph, it starts collecting maximum values again.
More information
Remote command: Bargraph state: DISPlay:BARGraph:PHOLd[:STATe] on page 451 Bargraph reset: DISPlay:BARGraph:PHOLd:RESet on page 451
Measurement Time
Defines the measurement time used to analyze the signal. You can define a different measurement time for the bargraph, each scan range
defined in the scan table and the final measurement. If you perform a scan that is not based on a scan table (Current parameters), the measurement time for the scan is the same as for the bargraph.
In addition, you can define a separate measurement time for fixed frequency scans. Tip: Make sure to select a measurement time that is appropriate for the analyzed sig-
nal and that allows the various filters and detectors in the signal path to settle.
