Syntax and Commands
Syntax and Commands This section provides the following information: Command Syntax defines the command syntax and processing conventions. Command Groups describes command groups which lists the commands by function. Command Descriptions describes the notation of each of the commands in alphabetical order. Command Syntax You can control the operations and functions of the arbitrary/function generator through the GPIB interface using commands and queries.
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.
Syntax and Commands Figure 3-1 shows the five command message elements. Comma Header MMEMory:STATe:LOCK 1, ON Arguments Mnemonics Space 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: [:][[]...] A command header is made up of one or more mnemonics arranged in a hierarchical or tree structure.
Syntax and Commands Command Entry 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 characters 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.
Syntax and Commands Creating Commands 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.
Syntax and Commands Special Characters 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. Abbreviating Commands, Queries, and Parameters You can abbreviate most SCPI commands, queries, and parameters to an accepted short form.
Syntax and Commands Chaining Commands and Queries You can chain several commands or queries together into a single message.

Status and Events
Status and Events This section provides details about the status information and events the arbitrary/function generator reports. Status Reporting Structure The arbitrary/function generator status reporting functions conform to IEEE-488.2 and SCPI standards. Use the status reporting function to check for instrument errors and to identify the types of events that have occurred on the instrument. Figure 4-1 shows an outline of the instrument error and event reporting function.

Status and Events Standard/Event Status Block This block is used to report power on/off, command error, and command execution status. The block has two registers: the Standard Event Status Register (SESR) and the Event Status Enable Register (ESER). Refer to the Standard/Event Status Block shown at the bottom of Figure 4-1. Standard Event Status Register. The SESR is an eight-bit status register. When an error or other type of event occurs on the instrument, the corresponding bit is set.
Status and Events Registers The registers in the event reporting system fall into two functional groups: The Status Registers contain information about the status of the instrument. Enable Registers determine whether selected types of events are reported to the Status Registers and the Event Queue.
Status and Events Status Byte Register (SBR). The SBR is made up of 8 bits. Bits 4, 5 and 6 are defined in accordance with IEEE Std 488.2-1992 (see Figure 4-2). These bits are used to monitor the output queue, SESR, and service requests, respectively. 6 RQS 5 4 3 2 1 OSB 6 ESB MAV QSB EQS — MSS 7 0 — Figure 4-2: The Status Byte Register (SBR) Table 4-1: SBR bit functions Bit Function 7 (MSB) OSB Operation Status Bit. Indicates that an operation event has occurred. 6 RQS Request Service.
Status and Events Standard Event Status Register (SESR). The SESR records eight types of events that can occur within the instrument as shown in Figure 4-3. 7 6 5 4 3 2 1 0 PON URQ CME ME EXE DDE QYE RQC O PC Figure 4-3: The Standard Event Status Register (SESR) Table 4-2: SESR bit functions Bit Function 7 (MSB) PON Power On. Indicates that the power to the instrument is on. 6 URQ User Request. Indicates that an application event has occurred.
Status and Events Operation Event Register (OEVR). This register has the same content as the Operation Condition Register. Operation Condition Register (OCR). The Operation Condition Register is made up of six bits, which note the occurrence of three different types of events as shown in Figure 4-4.
Status and Events Questionable Event Register (QEVR). This register has the same content as the Questionable Condition Register. Questionable Condition Register (QCR). The Questionable Condition Register is made up of sixteen bits which not the occurrence of only one type of event. 15 14 13 12 11 10 9 8 7 6 5 4 FREQ 3 2 1 0 Figure 4-5: Questionable Condition Register (QCR) Table 4-4: QCR bit functions Enable Registers Bit Function 15 to 6 ––––– Not used 5 FREQ Frequency.
Status and Events Use the *ESC command to set the bits in the ESER. Use the *ESR? query to read the contents of the ESER. Figure 4-6 shows the ESER functions. 7 6 5 4 3 2 1 0 PON URQ CME ME EXE DDE QYE RQC O PC Figure 4-6: Event Status Enable Register (ESER) Service Request Enable Register (SRER). The SRER consists of bits defined exactly the same as bits 0 through 7 in the SBR. You can use this register to define which events will generate service requests. The SRER bit 6 cannot be set.
Status and Events Questionable Enable Register (QENR). The QENR consists of bits defined exactly the same as bits 0 through 15 in the QEVR register (see Figure 4-9). You can use this register to control whether the QSB in the SBR is set when an event occurs and the corresponding QEVR bit is set. Use the STATus:QUEStionable:ENABle command to set the bits in the OENR. Use the STATus:QUEStionable:ENABle? query to read the contents of the OENR.
Status and Events Messages and Codes Error and event codes with negative values are SCPI standard codes. Error and event codes with positive values are unique to the AFG3000 Series Arbitrary/Function Generators. Table 4-5 lists event code definitions. When an error occurs, you can find its error class by checking for the code range in Table 4-6 through Table 4-14. Events in these tables are organized by event class.
