Output one of user-defined waveforms stored in the internal or in a USB
memory
To output a user-defined waveform, you must first save the file in the internal or
USB memory. You can save up to four user-defined waveforms in the internal
waveform memory. Waveform data in the Edit Memory can also be output, but the
contents of Edit Memory is deleted when the instrument power is turned off.
NOTE. When the arbitrary/function generator outputs an Arb waveform, the
peak-to-peak voltage of the measurement result is the same as the setup value if the
waveform data is normalized.

Amplitude Modulation. Amplitude modulation is a modulation technique in which
the amplitude of the carrier frequency is modified by the amplitude of the modulating waveform (internal or external modulation source).
The modulation depth is expressed as a percentage and represents the extent of the
amplitude variation.
Frequency Modulation. Frequency modulation is a modulation technique in which
the carrier frequency is modified by the amplitude of the modulating waveform.
The carrier frequency must always be greater than or equal to the deviation. Also
the sum of the carrier frequency and deviation must be less than or equal to the
maximum frequency for the selected waveform.
AFG3000 Series Arbitrary/Function Generators Reference Manual 2-7
Reference
Phase Modulation. Phase modulation is similar to FM (Frequency modulation), but
in PM, the phase of the carrier waveform is varied by the amplitude of the modulating waveform.
Frequency Shift Keying. Frequency shift keying modulation is a modulation technique that shifts the output signal frequency between two frequencies: the carrier
frequency and the FSK Hop frequency.
Pulse Width Modulation. Pulse width modulation is a modulation technique in
which the width of a pulse waveform is varied by the voltage of the modulating
waveform.

Triggered Burst Mode. When a trigger event occurs in the burst mode, the waveform is output for the number of cycles specified by the Burst Parameter Menu.
Once the triggered burst mode is selected, the arbitrary/function generator will wait
for a trigger event to occur.
A specified number (burst count) of waveform cycles are output when the instrument receives a trigger input from the internal trigger source, an external trigger
source, a remote command, or the Manual Trigger button.
Gated Burst Mode. In the gated burst mode, the output is enabled or disabled based
on the internal gate signal, an external signal applied to the front panel Trigger
Input connector, or a remote command. While the gate signal is true or the front
panel Manual Trigger button is depressed, the instrument outputs a continuous
waveform.
When the trigger source is set to Internal, the trigger interval can be set. The setting range of trigger interval is 1 ms to 500 s. The default is 1 ms.
When the trigger source is set to External, you can select Positive or Negative as
the trigger slope. The instrument will trigger on the rising edge (Positive) or falling
edge (Negative) of the signal applied to the front-panel Trigger Input connector.

Number of Points. This bezel menu sets the number of points of the waveform to be
created or the length of Edit Memory. The point can be set to a value in the following range:
Waveform Length: 2 to 131,072
If a waveform is already written to Edit Memory and Number of Points is set to a
value smaller than the number of points in that waveform, then the data for the
points starting at that value plus one will be lost. For example, if Number of Points
is set to 500 in the state where a waveform with 1000 points has been written to
Edit Memory, the waveform data for points 1 to 500 will remain without change
but the data from point 501 will be lost.
If a waveform is already written to Edit Memory and Number of Points is set to a
value greater than the number of points in that waveform, then the data for the
points starting at that value plus one to the point identified by the Number of
Points will be set to the zero level. For example, if Number of Points is set to 1500
in the state where a waveform with 1000 points has been written to Edit Memory,
the waveform data for points 1 to 1000 will remain without change and the data
from point 1001 to point 1500 will be set to zero level. See Figure 2-3 for an example using the Number of Points parameter.

Syntax and Commands
Command and Query
Structure
Commands consist of set commands and query commands (usually simply called
commands and queries). Commands change instrument settings or perform a
specific action. Queries cause the instrument to return data and information about
its status.
Most commands have both a set form and a query form. The query form of the
command is the same as the set form except that it ends with a question mark.
For example, the set command DISPlay:CONTrast has a query form
DISPlay:CONTrast?. Not all commands have both a set and a query form; some
commands are set only and some are query only.
A few commands do both a set and query action. For example, the *CAL? command
runs a self-calibration program on the instrument, then returns the result of the calibration.
A command message is a command or query name, followed by any information
the instrument needs to execute the command or query. Command messages
consist of five element types.
Table 3-2 lists and describes the five different element types.
Table 3-2: Command message elements
Symbol Meaning
<Header> The basic command name. If the header ends with a question mark, the
command is a query. The header may begin with a colon (:) character; if
the command is concatenated with other commands the beginning colon
is required. The beginning colon can never be used with command headers beginning with a star (*).
<Mnemonic> A header subfunction. Some command headers have only one mne-
monic. If a command header has multiple mnemonics, they are always
separated from each other by a colon (:) character.
<Argument> A quantity, quality, restriction, or limit associated with the header. Not all
commands have an argument, while other commands have multiple arguments. Arguments are separated from the header by a <Space>. Arguments are separated from each other by a <Comma>.
<Comma> A single comma between arguments of multiple-argument commands. It
may optionally have white space characters before and after the comma.
<Space> A white space character between command header and argument. It may
optionally consist of multiple white space characters.

Figure 3-1: Command message elements
Commands. Commands cause the instrument to perform a specific function or
change one of its settings. Commands have the structure:
[:]<Header>[<Space><Argument>[<Comma><Argument>]...]
A command header is made up of one or more mnemonics arranged in a hierarchical or tree structure. The first mnemonic is the base or root of the tree and each
subsequent mnemonic is a level or branch of the previous one. Commands at a
higher level in the tree may affect those at a lower level. The leading colon (:)
always returns you to the base of the command tree.
Queries. Queries cause the arbitrary/function generator to return information about
its status or settings. Queries have the structure:
[:]<Header>?
[:]<Header>?[<Space><Argument>[<Comma><Argument>]...]
You can specify a query command at any level within the command tree unless
otherwise noted. These branch queries return information about all the mnemonics
below the specified branch or level.
Query Responses. When a query is sent to the arbitrary/function generator, only
the values are returned. When the returned value is a mnemonic, it is noted in
abbreviated format, as shown in Table 3-3.

Syntax and Commands
Command Entry
SCPI Commands and
Queries
Follow these general rules when entering commands:
Enter commands in upper or lower case.
You can precede any command with white space characters. White space char-
acters include any combination of the ASCII control characters 00 through 09
and 0B through 20 hexadecimal (0 through 9 and 11 through 32 decimal).
The instrument ignores commands that consists of just a combination of white
space characters and line feeds.
The arbitrary/function generator uses a command language based on the SCPI standard. The SCPI (Standard Commands for Programmable Instruments) standard
was created by a consortium to provide guidelines for remote programming of
instruments. These guidelines provide a consistent programming environment for
instrument control and data transfer. This environment uses defined programming
messages, instrument responses and data formats that operate across all SCPI
instruments, regardless of manufacturer.
The SCPI language is based on a hierarchical or tree structure that represents a
subsystem (see Figure 3-2). The top level of the tree is the root node; it is followed
by one or more lower-level nodes.
TRIGger
Root nodes
SEQuence
SLOPe SOURce TIMer
Lower-level nodes
Figure 3-2: Example of SCPI subsystem hierarchy tree
You can create commands and queries from these subsystem hierarchy trees.
Commands specify actions for the instrument to perform. Queries return measurement data and information about parameter settings.
3-4 AFG3000 Series Arbitrary/Function Generators Reference Manual
Syntax and Commands
Creating Commands
Parameter Types
SCPI commands are created by stringing together the nodes of a subsystem hierarchy and separating each node by a colon.
In Figure 3-2, TRIGger is the root node and SEQuence, SLOPe, SOURce, and TIMer
are lower level nodes. To create an SCPI command, start with the root node
TRIGger and move down the tree structure adding nodes until you reach the end of
a branch. Most commands and some queries have parameters; you must include a
value for these parameters. The command descriptions, which begin on page 3-15,
list the valid values for all parameters.
For example, TRIGger:SEQuence:SOURce EXTernal is a valid SCPI command
created from the hierarchy tree in Figure 3-2.
Parameters are indicated by angle brackets, such as <file_name>. There are several
different types of parameters, as listed in Table 3-4. The parameter type is listed
after the parameter. Some parameter types are defined specifically for the arbi-
trary/function generator command set and some are defined by SCPI.

Special Characters
Abbreviating Commands,
Queries, and Parameters
The Line Feed (LF) character or the New Line (NL) character (ASCII 10), and all
characters in the range of ASCII 127-255 are defined as special characters. These
characters are used in arbitrary block arguments only; using these characters in
other parts of any command yields unpredictable results.
You can abbreviate most SCPI commands, queries, and parameters to an accepted
short form. This manual shows these commands as a combination of upper and
lower case letters. The upper case letters indicate the accepted short form of a
command, as shown in Figure 3-3. The accepted short form and the long form are
equivalent and request the same action of the instrument.

suffix is used.

Syntax and Commands
Chaining Commands and
Queries
You can chain several commands or queries together into a single message. To
create a chained message, first create a command or query, then add a semicolon
(;), and finally add more commands or queries and semicolons until you are done.
If the command following a semicolon is a root node, precede it with a colon (:).
Figure 3-4 illustrates a chained message consisting of several commands and
queries. The chained message should end in a command or query, not a semicolon.
Responses to any queries in your message are separated by semicolons.
:SOUR:FREQ:FIX 100;:OUTP:STAT ON;:SOUR:VOLT:AMPL?;:TRIG:SEQ:TIM?
First command Second command First quer y Second query
The response from this chained message might be: 1.000E0;1.000E-3
Response from first query
Response from second query
Figure 3-4: Example of chaining commands and queries
If a command or query has the same root and lower-level nodes as the previous
command or query, you can omit these nodes. In Figure 3-5, the second command
has the same root node (SEQuence) as the first command, so these nodes can be
omitted.

If the decimal numeric argument refers to voltage, frequency, impedance, or time,
you can express it using SI units instead of using the scaled explicit point input
value format <NR3>. (SI units are units that conform to the System International
d’Unites standard.) For example, you can use the input format 200 mV or 1.0 MHz
instead of 200.0E–3 or 1.0E+6, respectively, to specify voltage or frequency.
