See Chapter 3.4.2, "Means of manual interaction", on page 35 for basic information on manual operation of the instrument.
●
Remote control
Create programs to automatize repeating settings, tests and measurements. A
controller PC with remote access to the instrument runs the programs.
See Chapter 3.4.3, "Remote control", on page 44 for an overview of the interfaces
provided for remote control.
3.4.2 Means of manual interaction
To configure the R&S NGC100 manually, use the front panel controls, see Chapter 3.2.1, "Front panels", on page 26. The display shows the current settings, menus
and dialogs, when you perform your settings.
For manual interaction with the R&S NGC100, you have several methods that you can
use as an alternative to perform a task:
●

Understanding the display information
Depending on the instrument models, up to three channel display area are shown on
the screen layout. Each channel display area displays the voltage, current values and
the operating mode and functions of the output. For all models, the display shows a
device status bar at the top of the display and the supported channel display area at
the bottom. On the right-hand side of the screen layout, an interactive softkey menu set
the view of measuring mode and provides access to the selected measurement functions and settings.
The result fields display on the screen layout depend on the instrument models:
●
The statistic readings of minimum, maximum, mean and count values for voltage
and current are displayed simultaneously on R&S NGC101(-G) and R&S NGC102(G) models. For R&S NGC103(-G) model, the statistic function is available in the
background and is accessed via the [MEAS] > "STATS" softkeys.
●
For R&S NGC101(-G) model, the channel display area is divided into the section of
"Set" and "Meas" (sense) display channel area. Below the "Meas" display channel
area is the display of statistic readings of minimum, maximum, mean and count values for voltage and current.

Power derating
For more information on how to navigate menus, dialogs and data entry in the instrument, see Chapter 3.4.2.2, "Accessing the functionality", on page 42 and Chapter 3.4.2.3, "Entering data", on page 43.
To go into live-mode of the instrument, see "To go into live-mode" on page 42.
4.2 Power derating
The degrading graph labeled on the frontpanel of R&S NGC101(-G) and
R&S NGC102(-G) models show the derating curve of current quoted as a function of
voltage at maximum output power schematically. For R&S NGC103(-G), see Figure 4-2.
As specified, the R&S NGC100 provides high current and voltage ranges. For example, with R&S NGC103(-G), you can output up to 3 A and 32 V for each channel. However, if you set both parameters to maximum values, the resulting power would exceed
the maximum 33 W output power per channel of the R&S NGC100. Therefore, the
instrument automatically reduces the maximum current when the voltage increases
above 11 V (in this example), to keep within the 33 W maximum output power per
channel. This function protects the instrument from overload by decreasing the current
as the voltage increases.
The following output performance graph for R&S NGC103(-G) shows the combination
of the set voltage and current limit results.
Figure 4-2: Output performance graph
According to the basic electrical formula for power (P) = current (I) x voltage (V), the
following results for the maximum power per channel:
●
R&S NGC101(-G): 100 W per channel
●

mode", on page 186 and Chapter 13.2, "Parallel mode", on page 187.
4.3 Operation modes
The R&S NGC100 operates in two different modes, i.e. CV and CC. The instrument
switches automatically between CV and CC depending on the connected load.
CV mode
Figure 4-3 shows that if the instrument is in the range of voltage regulation, the output
voltage Vout remains constant while the current may increase to its maximum value Imax
when the connected load is increasing. In CV mode, the font text in the channel display
area changes to green.
See "Operating modes" on page 39.

The current Imax corresponds to the current setting adjustable in the instrument.
If Iout reaches Imax, the instrument switches to CC mode, i.e. the output current remains
constant and limited to Imax even if the load increases. Instead, the output voltage Vout
decreases below Vset. In a short circuit, the output voltage drops towards zero. In CC
mode, the font text in the channel display area changes to red.

Channel output
In general, operating in multi-quadrant mode requires a multi-quadrant power supply.
The R&S NGC100 is a one-quadrant power supply which is able to provide positive
voltage or positive current. By connecting the positive terminal of "Ch 1" output to negative terminal of "Ch 2" output as reference ground, you can generate a range between
-32 V and +32 V. This does not refer to a negative display on the screen, but rather to
a connection with an identical voltage range. However, a negative current (current sink)
is not possible.
See Figure 5-3 for a connection example for R&S NGC103(-G), the connection for
R&S NGC102(-G) is identical.

5.3 Electronic fuse
Fuse linking function is not available for R&S NGC101(-G) model.
To protect a connected, sensitive output in general, the R&S NGC100 power supply
includes an electronic fuse which can be switched on individually for each channel.
A fuse delay can be applied to each channel and individual electronic fuses can be logically linked to switch off the interlinked channels if a fuse triggers.
For more information, see Chapter 5.3.2, "Fuse delay, fuse linking", on page 58 for
fuse delay and fuse linking configuration.

5.3.2 Fuse delay, fuse linking
The fuse delay and fuse linking functions provide the flexibility to handle a fuse tripped
event when it occurs. When the current for a channel exceeds the value Imax and the
fuse tripped event triggered, the affected channels are turned off according to the settings configured in the fuse delay and fuse linking.
With fuse delay function, it allows you to ignore the current peaks set above the current
limit that occurs during the time set in the fuse delay. This prevents the fuse to be triggered in case of a capacitive load.
With fuse linking function, it allows you to logically interlink channels with their electronic fuses. If a fuse trips during operation, all channels interlinked with this channel
are turned off.

4. Set the desired mode and threshold settings.
Example:
The following shows an example of linear operating mode which proportionally controls
the voltage set at the front panel of the instrument. An external power supply unit is
used as the source. The connection is established via plug-in terminal block connector
which is connected with the external source. A voltage signal (U+/U-) is used in this
example. See Figure 3-7 and Table 5-4.
Select a voltage of 5 V at the external source. Set the voltage value for Ch 1 to 1 V. If
you activate the "Analog In" function for Ch 1, the voltage value for Ch 1 is set to 50 %
of the previously selected voltage value. In this example, it would correspond to
500 mV.
If you increase the voltage for the external source to a maximum of 10 V, the voltage
value for Ch 1 is set to 100 % of the previously selected voltage value. In this example,
it would correspond to 1 V. Accordingly, if the output voltage for Ch 1 is controlled by
means of a current signal. This procedure requires the current interface connectors (I+/
I-). If you increase the current value for the external source to 20 mA, the voltage value
for Ch 1 is set to 100 % of the previously selected voltage value. In this example, it
would correspond to 1 V.

The R&S NGC100 series allows you to generate freely programmable waveforms
which can be reproduced within the limits set by the instrument for voltage and current
of the respective channel. To configure a waveform, you can use the control panel or
an externally created waveform, see"Using R&S HMExplorer software to create arbitrary waveform" on page 85.
Each channel has its own arbitrary memory which means that when an arbitrary waveform is generated and that the arbitrary waveform of the respective channel is then
started. Depending on the instrument models, up to three arbitrary waveform can be
generated. If arbitrary waveform is disabled, the respective channel is also disabled.
Access:
1. Press [Adv] key.
2. Select "EASY ARB" to configure the EasyArb menu.
Alternatively, press the shortcut key [Arb] to access the EasyArb menu.

Using R&S HMExplorer software to create arbitrary waveform
Alternatively, you can also use HMExplorer software to create arbitrary waveform. The
software allows you to create each point of a waveform by use of the editor. You can
add or delete individual points by using the"+" or "-" function. With the function "INTERPOLATION", the defined arbitrary points can be output interpolated.
Figure 5-25: Arbitrary-editor example (excerpt) R&S HMExplorer software
Once all arbitrary points have been created, the created signal can be transferred to
the instrument via interface by using the menu item "TRANSFER". The menu "TRANSFER" opens and allows you to select the respective R&S NGC100 channel and the
repetitions. Additionally, you can also activate the output to issue the signal directly at
the output and to view it on an oscilloscope.

The standard file formats *.csv or .txt, which The R&S NGC100 saves the data in ,
allow you to use a spreadsheet application program for analysis and evaluation. A
spreadsheet program displays the data either as numerals and text, or in graphical
form.
Consideration on data content depending on the used application
During a measurement, gaps can occur due to high process load, measurement speed
or exceeding file size. It can also occur that a measured parameter was not displayed
caused by configuration or exceeded ranges. The gaps result in empty cells designated as "nan" (not a number).
Consider, that not all spreadsheet applications can evaluate "nan" as a 0, which leads
to erroneous results, shown in the example.
Figure 7-11: "nan"- with correct and erroneous empty cell evaluation
Therefore, the R&S NGC100 provides a correction function that fills empty cells wit 0.
Consider the capability of the application that you use, and set the function correction
correspondingly.

8.1.1 LAN interface
The R&S NGC100 is equipped with a network interface and can be connected to an
Ethernet LAN (local area network). If you have assigned the corresponding rights, you
can use this interface for remote control and data transfer from a controller PC. Make
sure that you have connected the controller PC in the same network.
To establish a network connection, connect a commercial RJ-45 cable to the LAN port
of the instrument and to a PC or network switch.
For more information on the connection, see Chapter 8.2.1, "LAN connection",
on page 124.
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), and a DHCP server is available, all address information
can be assigned automatically.
●
Otherwise, the address must be set manually. Automatic private IP addressing
(APIPA) is not supported.
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.
1. NOTICE! Risk of network failure. Before connecting the instrument to the network
or configuring the network, consult your network administrator. Connection errors
may 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.
2. Connect a LAN cable to the LAN port.
See also Chapter 8.2.1, "LAN connection", on page 124.
3. For manual configuration, select [Setup] > "Interface" > "Ethernet" > "PARAMETER" softkey items.

8.1.2 USB interface
You can use the USB B interface for remote control and data transfer from a controller
PC. Remote control over USB requires the VISA library.
Connect a double-shielded USB cable between the USB port and PC for a USB connection. The R&S NGC100 supports "USB TMC" and "USB VCP" connection.
For more information on connection, see Chapter 8.2.2, "USB connection",
on page 126.
Access:
► Select [Setup] > "Interface" to select the desire USB interface.
For details, see "USB VCP" on page 118 and "USB TMC" on page 118.
USB VCP
The following requirements for USB-VCP driver installation are necessary:
●
A PC with operating system Windows XP, VISTA, Windows 7, Windows 8 (32Bit or
64Bit), Windows 10 or Windows 11.
●
Administrator rights are necessary for the installation of the driver.
The USB virtual COM port (USB-VCP) is a software interface that allows the communication to the R&S NGC100 using any terminal program (e.g. HMExplorer) via SCPI
commands once the corresponding Windows drivers have been installed. The actual
USB-VCP driver and software HMExplorer can be downloaded for free from the product homepage (http://www.rohde-schwarz.com/product/ngc100).
If a connection between PC and the instrument has been established and no
R&S NGC100 USB-VCP driver is installed, the PC operating system displays a "Found
New Hardware" wizard. In this case, the R&S NGC100 USB-VCP driver must be installed.
The HMExplorer window application provides the R&S NGC100 a terminal function
and also the option to create screenshots and editor function to create the EasyArb
table.
For more information of the driver installation and HMExplorer window application, see
the installation guide of the driver file and the internal HMExplorer help.
USB TMC
The USB Test & Measurement class (USB-TMC) is a protocol that allows GPIB-like
communication via USB interfaces and is a separate instrument class of the USB spec-
User Manual 1179.1687.02 ─ 01

R&S®NGC100
Network operation and remote control
Remote control interfaces and protocols
ification. The USB-TMC protocol supports service queries, triggers, and other GPIBspecific instructions.
VISA drivers are installed and that it can be used directly in the corresponding environments. The driver is included in the NI-VISA package and can be downloaded at http://
www.ni.com/downloads/ni-drivers/.
A major benefit of the USB TMC class is that by sampling specific registers, the controlling software can determine if commands have been terminated and if they have
been processed correctly. With USB-VCP, communication with instrument requires
analysis and polling mechanisms within the controlling software which may significantly
strain the interface of the measurement instruments. The TMC status registers solve
this problem with the USB TMC in the same manner as in the case with the GPIB interface for the hardware via the corresponding control lines.
HMExplorer
The window application supports the communication via LAN and USB VCP only.
For more information of the VISA driver installation, see the installation guide of the
VISA driver file.
Once the driver is installed, the "USB Test and Measurement Device (IVI)" is displayed
in the "Device Manager" window, see Figure 8-4.

8.1.3 GPIB interface (IEC/IEEE bus interface)
The R&S NGCxxx-G models are equipped with an integrated GPIB interface at the
rear panel.
The GPIB interface sometimes called the General Purpose Interface Bus (GPIB), is a
general purpose digital interface system that can be used to transfer data between two
or more devices. Some of its key features are:
●
Up to 15 instruments can be connected
●
The total cable length is restricted to a maximum of 15 m; the cable length between
two instruments should not exceed 2m
●
A wired "OR" connection is used if several instruments are connected in parallel
GPIB instrument address
To operate the instrument via remote control, it must be addressed using the GPIB
address. Connect the IEC 625/IEEE 488 connector of the R&S NGC100 to the controller PC with a double-shielded GPIB bus interface cable.
For more information on the connection, see Chapter 8.2.3, "GPIB connection",
on page 126.

front panel devices via a WEB interface. The central tool for this type of configuration is
a browser.
LXI-compatible devices are divided into three classes, A, B and C, where the functionality of the classes is based on each other hierarchically:
Figure 8-6: LXI classes
●
Class C devices are characterized by a uniform LAN implementation including an
ICMP ping responder for diagnostic purposes. Devices can be configured with a
WEB browser.
A LAN Configuration Initialize (LCI) mechanism resets the LAN configuration. Class
C LXI devices are also intended to support automatic detection in a LAN via VXI-11
discovery protocol and programming using IVI drivers.
●
Class B adds the IEEE 1588 Precision Time Protocol (PTP) and peer-to-peer communication to base class C. With IEEE 1588, all devices within a network can automatically synchronize to the most accurate available clock, and then provide timestamps or synchronization signals for all devices with exceptional accuracy.
●
Class A devices also contain the eight-channel hardware trigger bus (LVDS interface) according to the LXI standard.
Class A and B devices can send and receive software triggers through LAN messages
and communicate with each other without using the controller.
The power supplies of the R&S NGC100 series meet the general requirements of the
LXI Class C and correspond to the version 1.5 (LXI Core 2016). Advanced features are
not supported.
A key component of an LXI certification is the IVI device driver (Interchangeable Virtual
Instrument). Here IVI.NET drivers are provided, which are based on the .NET framework 4 of Microsoft. LabView and LabWindows/CVI drivers built on LabWindows/CVI
2012 are also available. The latest copy of the IVI.NET driver is available for download
form the product homepage http://www.rohde-schwarz.com/product/ngc100.
In addition to the features described above, the device provides the following LXI-related functions:
●
Displays the current device settings
●
Remote control of the device within the WEB-Browser
The Ethernet interface has an integrated web server, you can access the instrument
with its corresponding IP address in the address line of the browser. See Figure 8-7.

8.1.5 SCPI
SCPI (Standard Commands for Programmable Instruments) commands - messages are used for remote control. Commands that are not taken from the SCPI standard follow the SCPI syntax rules. The instrument supports the SCPI version 1999. The SCPI
standard is based on standard IEEE 488.2 and aims at the standardization of devicespecific commands, error handling and the status registers. The tutorial "Automatic
Measurement Control" - A tutorial on SCPI and IEEE 488.2" from John M. Pieper (R&S
order number 0002.3536.00) offers detailed information on concepts and definitions of
SCPI.
The requirements that the SCPI standard places on command syntax, error handling
and configuration of the status registers are explained in detail in the following sections. For more information, see Chapter 9, "Remote control commands", on page 133
and Chapter A, "Additional basics on remote control", on page 188.
8.1.6 VISA
VISA is a standardized software interface library providing input and output functions to
communicate with instruments. The I/O channel (LAN or USB) is selected at initializa-

tion time by means of a channel-specific resource string. For more information about
VISA, refer to its user documentation.
8.2 Setting up remote control connection
The resource string represents an addressing scheme that is used to establish a communication session with the instrument. The following sections show the resource
string format used when setting up a remote connection via the various interfaces:
The end character must be set to line feed (LF).
8.2.1 LAN connection
For remote control via a network, the PC and the instrument must be connected over
the LAN interfaces to a common network with TCP/IP network protocol. The instruments are connected with a commercial RJ45 cable (shielded or unshielded Twistedpair CAT 6+).
The TCP/IP network protocol and the associated network services are preconfigured
on the instrument. Software for instrument control and (for specified protocols only) the
VISA program library must be installed on the controller.
Identifying instruments in a network
If several instruments are connected to the network, each instrument has its own IP
address and associated resource string. The controller identifies these instruments by
the resource string.
See Chapter 8.1.1, "LAN interface", on page 114 for configuring the LAN parameters.
The VISA resource string is required to establish a communication session between
the controller and the instrument in a LAN. The resource string is a unique identifier,
composed of the specific IP address of the instrument and some network and VISAspecific keywords.
To set up the connection, the IP address of the instrument is required. It is part of the
resource string used by the program to identify and control the instrument. The
resource string has the form:
TCPIP::<host address>[::<LAN device name>][::INSTR]
= designates the network protocol
TCPIP
host address
= designates the IP address or hostname of the instrument
[::LAN device name] = defines the protocol and the instance number of a subinstrument
[::INSTR]
= indicates the instrument resource class (optional)
User Manual 1179.1687.02 ─ 01
124
R&S®NGC100
Network operation and remote control
Setting up remote control connection
The IP address (host address/computer name) is used by the programs to identify and
control the instrument. It is automatically assigned by the DHCP server the first time
that the device is registered on the network.
Example:
If the instrument has the IP address 192.1.2.3, the valid resource string is:
TCPIP::192.1.2.3::INST
See Figure 3-2.
VXI-11
TCPIP::<host address>[::inst0][::INSTR]
[::inst0] = LAN device name indicates that the VXI-11 protocol is used (optional)
[::inst0] selects the VXI-11 protocol by default and can be omitted.
Example:
TCPIP::192.1.2.3::INSTR
HISLIP
High-Speed LAN Instrument Protocol (HiSLIP) is a TCP/IP-based protocol for remote
instrument control of LAN-based test and measurement instruments. It was specified
by the IVI Foundation and is intended to replace the older VXI-11 protocol. To start
remote control session with HiSLIP, the valid resource string is:
TCPIP::192.1.2.3::HISLIP
Socket communication
TCPIP::<host address>::<port>::SOCKET
= designates the network protocol
TCPIP
host address = designates the IP address or hostname of the instrument
port
= determines the used port number
SOCKET
= indicates the raw network socket resource class
Socket communication requires the specification of the port (commonly referred to as
port number) and of "SOCKET" to complete the VISA resource string with the associated protocol used.
The default registered port for socket communication is port 5025. See also Figure 3-2.
Example:
TCPIP::192.1.2.3::5025::SOCKET

8.2.2 USB connection
See Chapter 8.1.2, "USB interface", on page 118 for configuring the USB parameters.
For remote control over the USB connection, the PC and the instrument must be connected over the USB B interface at the rear panel of the instrument. Depending on the
used USB port, the connection requires the VISA library or a USB VCP driver to be
installed.
On the controller, you need to install any application for instrument control, for example
the R&S HMExplorer, and if available, a VISA program library. VISA detects and configures the Rohde & Schwarz instrument automatically when the USB connection is
established. You do not have to enter an address string or install a separate driver.
The resource string represents an addressing scheme that is used to establish a communication session with the instrument. It is based on the instrument address and
some instrument- and vendor-specific information. The USB resource string syntax is
as follows:
●
USB TMC
USB::<vendor ID>::<product ID>::<serial number>[::INSTR]
USB
= denotes the used interface
<vendor ID>
= is the manufacturer ID
<product ID>
= is the product identification of the instrument
<serial number> = is the individual serial number on the rear of the instrument
[::INSTR]
= indicates the instrument resource class (optional)
Example:
USB0::0x0AAD::
0x0197::3657.0005<device_variant>-<device_serial_number>::
INSTR
●
USB VCP
ASRL<COM>::INSTR, where "COM" refers to the COM port number shown on the
controlling PC. (e.g. ASRL15::INSTR)
8.2.3 GPIB connection
The R&S NGCxxx-G models are equipped with a GPIB interface. The GPIB interface is
at the rear panel.
To control the instrument over the GPIB bus interface, the instrument and the controller
must be connected with a GPIB bus cable. A GPIB bus card, the card drivers and the
program libraries for the programming language used must be provided in the controller.
The controller addresses the instrument within the GPIB bus channel, providing
addresses from 0 to 30. The R&S NGC100 has the factory-set address of 20, which
you can adjust it according to your environment manually. An instrument preset does
not affect the GPIB address.

Network operation and remote control
Starting and stopping remote control
See Remote control via SCPI for additional information on the characteristics, control
commands and messages of the GPIB interface.
See Chapter 8.1.3, "GPIB interface (IEC/IEEE bus interface)", on page 120 for configuring the GPIB parameters.
To set up the connection, the GPIB address of the instrument is required. It is part of
the resource string used by the program to identify and control the instrument over the
GPIB interface. The resource string has the form:
GPIB<controller_card>::<GPIB_address>::INSTR
You can distinguish between the different GPIB controller cards with "GPIB0", "GPIB1",
"GPIB2" and etc.
If the VISA implementation supports the GPIB interface, you can optionally define the
VISA Instrument Control Resource (INSTR). It is used to define the basic operations
and attributes for a device, such as reading, writing, or triggering.
Example:
GPIB::28
28 is the selected GPIB bus channel.
To change the GPIB address, see Chapter 8.1.3, "GPIB interface (IEC/IEEE bus interface)", on page 120.
8.3 Starting and stopping remote control
When you switch on the instrument, it is always in manual operation state ("local"
state). You can operate it using the controls on the front panel. To switch to remote
control operation, proceed as follows.
Starting a remote control session
To start remote control:
1. Send a command from the controller.
2. VXI-11 protocol (LAN or USB interface): Use &GTR interface message.
The instrument switches to remote control and executes the command.
On the screen, a status symbol indicates that remote control is active. The display
remains on and you can still operate it manually using the front panel controls.
Returning to manual operation
The instrument switches back to manual operation when the remote connection is
closed. But you can return to manual operation manually or via remote control also.

To return to manual control:
1. Select
"UNLOCK" softkey.
2. VXI-11 protocol (LAN or USB interface): Use &GTL interface message.
The instrument switches to manual control.
8.4 Status reporting system
The status reporting system stores all information on the current operating state of the
instrument and errors which have occurred. This information is stored in the status registers and in the error queue. You can query both via RS-232, USB, GPIB or LAN interface (STATus... commands).
8.4.1 Structure of a SCPI status register
Each standard SCPI register consists of 2 or 3 parts (Event, Condition and Enable register). Each part has a width of 16 bits and has different functions. The individual bits
are independent of each other, i.e. each hardware status is assigned a bit number
which is valid for all 2 or 3 parts. Bit 15 (the most significant bit) is set to zero for all
parts. Thus the controller can process contents of the register parts as positive integers.
STATus:QUEStionable:INSTrument:ISUMmary1 exists as often as device channels are available (e.g. R&S NGC103 = 3 channels = 3 status register). Accordingly,
the description text of the channel information changes in Figure 8-8 (e.g. instrument 1
= channel 1, instrument 2 = channel 2 etc.).
Depending on the value of the read register, you can draw conclusions on the current
status of the device. For example, when the unit operates in constant voltage, the
result of the returned ISUM register is a decimal "2" which corresponds the binary
value of "0000000000000010".

Figure 8-8: Structure of the STATus:QUEStionable register
Any part of a status register system can be read by query commands. A decimal value
is returned and represents the bit pattern of the requested register. Each SCPI register
is 16 bits wide and has various functions. The individual bits are independent, i.e. each
hardware status is assigned to a bit number.
Bits 9 to 12 are still "free" resp. unused (always return a "0"). Certain areas of the registers are not used. The SCPI standard defines only the "basic functions". Some devices offer an advanced functionality.
Description of the status register parts
The SCPI standard provides two different status registers:
CONDition
●
The CONDition register queries the actual state of the instrument. If you want to
query the constant voltage or current mode, you have to use the CONDition register.
The CONDition register delivers a "1" (first bit set) in constant current mode (CC) and
a "2" (second bit set) in constant voltage mode (CV).
If the correct channel is selected and the red LED of the channel button lights up (CC
mode), the query of the CONDition register must deliver a "1".

Example:
STAT:QUES:ISUM1:COND?
EVENt
●
The EVENt status register is set (1) until it is queried. After reading (query), the
EVENt status register is set to zero.
The description of registers is only used for general explanation. Due to the complexity,
we recommend the general accessible SCPI standard document for more detailed
information.

8.4.2 Contents of the status registers
8.4.2.1
Event status register (ESR) and event status enable register (ESE)
The ESR is defined in IEEE 488.2. It can be compared with the EVENt part of a SCPI
register. The event status register can be read out using the command *ESR?. The
ESE corresponds to the ENABle part of a SCPI register. If a bit is set in the ESE and
the associated bit in the ESR changes from 0 to 1, the ESB bit in the STB is set. The
ESE register can be set using the command *ESE and read using the command
*ESE?.

Application of the status reporting system
The purpose of the status reporting system is to monitor the status of one or several
instruments in a test system. In particular, it monitors continuous measurements to
detect errors in the signal. The controller must receive and evaluate the information of
all devices.
The following standard methods are used:
●
Query of a specific register by commands
●
Query of the error queue
These methods are described in the following sections.
Query of an instrument status
Each part of any status register can be read using queries.
There are two types of commands:
●
The common commands *ESR?, *IDN?, *STB? query the higher-level registers.
●
The commands of the STATus system query the SCPI registers
(STATus:QUEStionable)

R&S®NGC100
Network operation and remote control
Status reporting system
The returned value is always a decimal number that represents the bit pattern of the
queried register. This number is evaluated by the controller program.
Decimal representation of a bit pattern (binary weights)
The STB and ESR registers contain 8 bits, the status registers 16 bits. The contents of
a status register are specified and transferred as a single decimal number. To make
this possible, each bit is assigned a weighted value. The decimal number is calculated
as the sum of the weighted values of all bits in the register that are set to 1.
Figure 8-10: Decimal representation of a bit pattern
8.4.3 Error queue
Each error state in the instrument leads to an entry in the error queue. The entries of
the error queue are detailed plain text error messages. You can look them up in the
error log or via remote control using SYSTem:ERRor[:NEXT]?. Each call of
SYSTem:ERRor[:NEXT]? provides one entry from the error queue. If no error messages are stored, the instrument responds with 0, "No error".
For further description of the error queue and the device error codes, please refer to
Chapter 9.1, "Common setting commands", on page 133.

Configuration commands
Each channel of the power supply is considered as separate "instrument", which is
required by the SCPI standard. Therefore, the SCPI commands use the INSTRument
node to select a channel.
You can only address the number of channels a device is equipped with, e.g. two channels for the R&S NGC102(-G) and three channels for the R&S NGC103(-G).
Example: Selecting a channel
You can select a channel either with an OUTput parameter, or just by the channel
number. This example lists all ways how you can select and query a selected channel.

How to clean the product is described in "Cleaning the product" on page 12.
Do not use any liquids for cleaning. Cleaning agents, solvents, acids and bases can
damage the front panel labeling, plastic parts and display.
12.2 Changing fuses
If the product does not start, it is possible that a blown fuse is the cause. The fuse is
located in the socket of the power supply.
For details on changing fuses, see "Replacing the power fuse" on page 23.
12.3 Internal battery replacement
An internal CR2032 coin cell battery powers the real-time clock circuit which provides
continuous time stamp for the instrument. If the battery fails, the system clock and time
stamp for the logging function are not available but other instrument functions are not
affected.
Under normal usage at room temperature, the battery is expected to last up to 10
years. However, the battery life expectancy is reduced if the device is stored at temperature above 40°C for an extended period of time.
If the instrument cannot retain the date and time settings after turning off the AC input,
the battery is discharged.

Applications
Series mode
13 Applications
To increase output voltage and currents, it is possible to operate the channels in series
or parallel mode. In general, the output voltages of R&S NGC100 to be combined are
independent.
For safety information, see Chapter 3.1.6, "Connecting to power", on page 22.
13.1 Series mode
This type of interconnection adds the individual output voltages. The same current
flows through all outputs. The current limits for the outputs wired in series should be
set to the identical value. If one of the outputs exceeded the current limit, the total voltage will naturally collapse. See Chapter 4.3, "Operation modes", on page 52.
It is advisable to set the voltages of all connected channels voltages to a similar value
to distribute the loads evenly (not absolutely necessary). When all three channels are
connected in a series mode and if a (low resistance) load is connected; there is a
chance of damaging a channel when that channel is switched off. This is due to the
protection diode working as a bypass to connect the other channel in a series mode.
Once the protection diode is shorted, the channel will be defective.
Therefore, it is necessary to always have all channels or no channel at all switched on.
If the instrument switches to constant current (CC) mode during a series connection,
the voltage display becomes inaccurate.

186
R&S®NGC100
Applications
Parallel mode
13.2 Parallel mode
If it is necessary to increase the total current, the power supply outputs must be wired
in parallel. The maximum total current is the sum of the individual currents of all sources connected in parallel. The output voltages for the individual outputs should be set
to the same voltage value as precisely as possible. For slight voltage differences, it is
common in this operating mode to first charge a voltage output up to the current limit;
the other voltage output provides the remaining current. See "Principles of operation in
parallel mode" on page 187.
For power supplies that are connected in parallel, it is possible that compensating currents flow within the power supplies. The use of power supplies by other manufacturers, which are potentially not overload proof, can cause destruction of these units as
currents may be distributed unevenly.
Figure 13-2: Example of parallel connection
Principles of operation in parallel mode
Generally, a higher current is first supplied from the channel with the higher output voltage. Once this channel reaches its power limit, the remaining current is made available
by the channel that is connected in parallel. In this scenario, it is unpredictable which
channel supplies the higher current because it is also possible for channels with identical voltage values to display a low voltage difference.
By increasing the voltage slightly, the load distribution can be manipulated. If the voltage for a channel is to be increased by 50 mV, for instance (by a set of identical
cables), the current will initially be provided by this channel.
If you wish to distribute the load to multiple channels, it is recommended to set the current limit of the channel that is to supply the main current to a fraction of the current.
This approach handles the semiconductor with care and improves the heat dissipation,
as the power loss is distributed more evenly.

Annex
A Additional basics on remote control
A.1 Messages and SCPI command structure
A.1.1 Messages
Instrument messages are employed in the same way for all interfaces, if not indicated
otherwise in the description.
●
Structure and syntax of the instrument messages: Chapter A.1.2, "SCPI command
structure", on page 189
●
Detailed description of all messages: Chapter 9, "Remote control commands",
on page 133
There are different types of instrument messages:
●
Commands
●
Instrument responses
Commands
Commands (program messages) are messages which the controller sends to the
instrument. They operate the instrument functions and request information. The commands are subdivided according to two criteria:
Effects on the instrument:
●
Setting commands cause instrument settings such as a reset of the instrument or
setting the output voltage.
●
Queries return data for remote control, e.g. for identification of the instrument or
polling a parameter value. Queries are formed by appending a question mark to
the command header.
Applied standards:
●
The function and syntax of the common commands are precisely defined in standard IEEE 488.2. If implemented, they are used identically on all instruments. They
refer to functions such as management of the standardized status registers, reset
and self-test.
●
Instrument control commands refer to functions depending on the features of the
instrument such as voltage settings. Many of these commands have also been
standardized by the SCPI committee. These commands are marked as "SCPI
compliant" in the command reference chapters. Commands without this SCPI label
User Manual 1179.1687.02 ─ 01
188
R&S®NGC100
Additional basics on remote control
Messages and SCPI command structure
are device-specific, however, their syntax follows SCPI rules as permitted by the
standard.
Instrument responses
Instrument responses (response messages and service requests) are messages which
the instrument sends to the controller after a query. They can contain measurement
results, instrument settings and information on the instrument status.
GPIB Interface Messages
Interface messages are transmitted to the instrument on the data lines with the attention line (ATN) being active (LOW). They are used for communication between the controller and the instrument and can only be sent by a PC which has the function of a
GPIB bus controller. GPIB interface messages can be further subdivided into:
●
Universal commands act on all instruments connected to the GPIB bus without
previous addressing; universal commands are encoded in the range 0x10 through
0x1F. They affect all instruments connected to the bus and do not require addressing.
●
Addressed commands only act on instruments previously addressed as listeners;
addressed commands are encoded in the range 0x00 through 0x0F. They only
affect instruments addressed as listeners.
A.1.2 SCPI command structure
SCPI commands consist of a so-called header and, usually, one or more parameters.
The header and the parameters are separated by a whitespace. The headers can consist of several mnemonics (keywords). Queries are formed by appending a question
mark directly to the header. The commands can be either device-specific or deviceindependent (common commands). Common and device-specific commands differ in
their syntax.
Syntax for common commands
Common (= device-independent) commands consist of a header preceded by an asterisk (*) and possibly one or more parameters.
Table A-1: Examples of common commands
Command
Command name
Description
*RST
Reset
Resets the instrument.
*ESE
Event Status Enable
Sets the bits of the event status
enable registers.
*ESR?
Event Status Query
Queries the content of the event
status register.
*IDN?
Identification Query
Queries the instrument identification string.

Additional basics on remote control
Messages and SCPI command structure
Syntax for device-specific commands
For demonstration purposes only, assume the existence of the following commands for
this section:
●
MEASure:CURRent[:DC]?
●
MEASure:VOLTage[:DC]?
●
FUSE[:STATe] {0 | 1}
●
FUSE[:STATe]?
Long and short form
The mnemonics feature a long form and a short form. The short form is marked by
uppercase letters, the long form corresponds to the complete word. You can enter
either the short form or the long form; other abbreviations are not permitted.
Example:
MEASure:CURRent? is equivalent to MEAS:CURR?.
Case-insensitivity
Uppercase and lowercase 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 selected by a suffix added to the command.
Numeric suffixes are indicated by angular brackets (<1...4>, <n>, <i>). They are
replaced by a value without brackets in the command.
SCPI prescribes that suffix counting starts with 1. Suffix 1 is the default state and used
when no suffix is specified.
Example:
Definition: CHANnel<n>:LIMit<n>:SOURCE?
Command: CHAN:LIM2:SOUR?
This command queries the 2nd limit in channel 1.
Optional mnemonics
Some command systems permit inserting or omitting certain mnemonics in the header.
These mnemonics are marked by square brackets. The instrument must recognize the
long command to comply with the SCPI standard. Some commands are shortened by
these optional mnemonics.
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.

Additional basics on remote control
Messages and SCPI command structure
Example:
CHANnel<n>[:ACQuistion]:MODE?
CHAN:ACQ:MODE? is equivalent to CHAN:MODE?.
Note that an optional mnemonic with a numeric suffix automatically selects 1 if you
omit the optional part of the command, e.g.:
Definition: CHANnel<n>:MEASurement:FUNCtions? [<n>]
Command: CHAN:MEAS:FUNC? queries the list of all function names in channel 1.
To query a single function, e.g. at index 3 in channel 2, include the optional CHANnel
suffix and the index of the function.
Command: CHAN2:MEAS:FUNC? 3
FUSE[:STATe] { ON }
FUSE:STAT ON is equivalent to FUSE ON.
A.1.3 SCPI parameters
Many commands are supplemented by a parameter or a list of parameters. The
parameters must be separated from the header by a whitespace (ASCII code 0 to 9, 11
to 32 decimal, e.g. blank). If several parameters are specified in a command, they are
separated by a comma ",".
Allowed parameters are:
●
Numeric values
●
Special numeric values
●
Boolean parameters
●
Text
●
Character strings
●
Block data
The required parameters and the allowed value range are specified in the command
description.
Numeric values
You can enter numeric values either with sign, decimal point or exponentially ("E" or
"e"). The mantissa range is up to 255 characters, the value range of the exponent is
-32000 to 32000. Values exceeding the resolution of the instrument are rounded up or
down.
Example:
VOLT 10V = VOLT 10
VOLT 100mV = VOLT 0.1
VOLT 500mV is equivalent to VOLT 500e-3.

Messages and SCPI command structure
Special numeric values
The text listed below are interpreted as special numeric values. In the case of a query,
the numeric value is provided.
●
MIN/MAX
●
MINimum and MAXimum denote the minimum and maximum value
Example:
VOLT:PROT? MAX
Returns the maximum numeric value.
Boolean parameters
Boolean parameters represent two states:
●
On (logically true), is represented by "On" or the numeric value "1"
●
Off (logically false), is represented by "Off" or the numeric value "0"
The instrument returns the numerical value when queried.
Example:
OUTP:STAT ON
OUTP:STAT? -> 1
Text
Text parameters observe the syntactic rules for key words, 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.
Example:
ARBitrary:TRIGgered:MODE
ARBitrary:TRIGgered:MODE SING
ARBitrary:TRIGgered:MODE? -> "SINGle"
Character strings
Strings must always be entered in quotation marks (' or ").
Example:
SYSTem:COMMunicate:SOCKet:IPADdress "192.168.1.128"
SYSTem:COMMunicate:SOCKet:IPADdress '192.168.1.128'
Block data
Block data is a transmission format which is suitable for the transmission of large
amounts of data. A command using a block data parameter has the following structure:

R&S®NGC100
Additional basics on remote control
Messages and SCPI command structure
Example:
HEADer:HEADer #45168xxxxxxxx
ASCII character # introduces the data block. The next number indicates how many of
the following digits describe the length of the data block. In the example, the four following digits indicate the length to be 5168 bytes. The data bytes follow. During the
transmission of these data bytes all end or other control signs are ignored until all
bytes are transmitted.
#0 specifies a data block of indefinite length. The use of the indefinite format requires a
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.
A.1.4 Overview of syntax elements
The following tables provide an overview of the syntax elements and special characters.
Table A-2: Syntax elements
:
A colon separates the mnemonics of a command.
;
The semicolon separates two commands within a program message. It does not alter the path.
,
A comma separates several parameters of a command.
?
A question mark forms a query.
*
An asterisk marks a common command.
"
Quotation marks introduce a string and terminate it.
A whitespace (ASCII-Code 0 to 9, 11 to 32 decimal, e.g. blank) separates the header from the
parameters.

Mnemonics in square brackets are optional and can be inserted into the header or be omitted.
Example:
FUSE[:STATe] { ON }
●
●
FUSE:STAT ON is equivalent to FUSE ON
{}
Parameters in curly brackets are optional and can be inserted once or several times, or be omitted.
Example:
VOLTage[:LEVel][:IMMediate][:AMPLitude] {<voltage> | MIN | MAX | UP |
●
DOWN }
The following are valid commands:
VOLT MAX
–
VOLT MIN
–
VOLT 10
–
A.1.5 Responses to queries
A query is defined for each setting command unless otherwise specified. The query is
set by the question mark at the end of the header. According to SCPI, the responses to
some query commands are subject to stricter rules than in defined standard IEEE
488.2.
●
The requested parameter is transmitted without a header.
ARBitrary:TRIGgered:MODE? -> "SINGle"
●
Maximum values, minimum values and all other quantities that are requested via a
special text parameter are returned as numeric values.
VOLT:PROT? MAX -> 32.500
●
Boolean values are returned as 0 (for Off) and 1 (for On).
OUTPut:STATe? -> 1
A.2 Command sequence and synchronization
A sequential command finishes the execution before the next command is starting. To
make sure that commands are actually carried out in a certain order, each command
must be sent in a separate command line.
As a general rule, send commands and queries in different program messages.

Command sequence and synchronization
A.2.1 Preventing overlapping execution
To prevent an overlapping execution of commands the commands *OPC, *OPC? or
*WAI can be used. All three commands cause a certain action only to be carried out
after the hardware has been set. The controller can be forced to wait for the corresponding action.
The R&S NGC100 series does not support parallel processing of remote commands. If
OPC? returns a "1", the device is able to process new commands.

*OPC?
Stops command processing until
1 is returned. It occurs after the
Operation Complete bit has been
set in the ESR. This bit indicates
that the previous setting has been
completed.
Sending *OPC? directly after the
command whose processing
should be terminated before other
commands can be executed.
*WAI
Stops further command processing until all commands have been
executed before *WAI.
Sending *WAI directly after the
command whose processing
should be terminated before other
commands are executed
Setting bit 0 in the ESE
Setting bit 5 in the SRE
Waiting for service request
(SRQ)
Command synchronization using *WAI or *OPC? is a good choice if the overlapped
command takes only little time to process. The two synchronization commands simply
block overlapped execution of the command. Append the synchronization command to
the overlapping command, for example:
SINGle; *OPC?
For time consuming overlapped commands, you can allow the controller or the instrument to do other useful work while waiting for command execution. Use one of the following methods:
*OPC with a service request
1. Set the OPC mask bit (bit no. 0) in the ESE: *ESE 1
2. Set bit no. 5 in the SRE: *SRE 32 to enable ESB service request.
3. Send the overlapped command with *OPC .
4. Wait for a service request.
The service request indicates that the overlapped command has finished.
*OPC? with a service request
1. Set bit no. 4 in the SRE: *SRE 16 to enable MAV service request.

R&S®NGC100
Additional basics on remote control
Command sequence and synchronization
2. Send the overlapped command with *OPC?.
3. Wait for a service request.
The service request indicates that the overlapped command has finished.
Event status register (ESE)
1. Set the OPC mask bit (bit no. 0) in the ESE: *ESE 1
2. Send the overlapped command without *OPC, *OPC? or *WAI.
3. Poll the operation complete state periodically (with a timer) using the sequence:
*OPC; *ESR?
A return value (LSB) of 1 indicates that the overlapped command has finished.
*OPC? with a short timeout
1. Send the overlapped command without *OPC, *OPC? or *WAI.
2. Poll the operation complete state periodically (by means of a timer) using the
sequence: (short timeout); *OPC?.
3. A return value (LSB) of 1 indicates that the overlapped command has finished. In
case of a timeout, the operation is ongoing.
4. Reset timeout to former value
5. Clear the error queue with SYStem:ERRor? to remove the "-410, Query interrupted" entries.
A.2.2 Using several threads in the controller application
Provided the programming environment of the controller application supports threads,
you can use separate threads for the application GUI and for controlling the instrument
using SCPI commands. A thread waiting for an *OPC? response does not block the
GUI or the communication with other instruments.
