Chapter 1 Getting Started Using This Chapter This chapter describes the Agilent E1300B/E1301B Mainframe, defines the instrument concept, and explains how plug-in modules are designated as instruments in the mainframe. This chapter also contains introductory programming examples showing how to read and set the mainframe’s clock and calendar. This chapter contains the following sections: • Mainframe Description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-1 • Instrument Definition .
GPIB Trig Out: Allows an instrument to output a negative-going pulse to indicate the occurrence of some event such as closing a channel on a Switchbox Instrument. The signal levels are standard TTL (0V to 5V). This pulse can be used to synchronize external equipment to the instrument (see Chapter 5 for examples). You direct the pulse from the appropriate instrument to the Trig Out port using the OUTP:STAT ON command.
1 Instrument Definition SCPI-compatible plug-in modules installed in the mainframe are treated as independent instruments each having a unique secondary GPIB address. As shown in Figure 1-3, each instrument is assigned a dedicated error queue, input and output buffers, status registers and, if applicable, dedicated mainframe memory space for readings or data.
Instrument Logical Addresses Instruments are identified by a logical address which directly relates to its GPIB secondary address. Instruments come from the factory with a preset logical address. You can change the factory setting during installation (see the "Agilent 75000 Series B Installation and Getting Started Guide" for instructions). A single-module instrument must have its logical address set to an integer multiple of 8 (0, 8, 16, 24, ... 240).
Example: Reading the Time This program reads and prints the time from the System Instrument’s internal clock. The computer used in the example is an Agilent Series 200/300 computer with Agilent BASIC as the program language. The computer interfaces to the mainframe using the General Purpose Interface Bus (GPIB). The GPIB interface select code is 7, the GPIB primary address is 09, and the GPIB secondary address is 00 (System Instrument). Resulting in a combined address of 70900.

Chapter 2 Using the Front Panel Using this Chapter This chapter shows you how to use the Agilent E1301B Mainframe’s front panel keyboard and display to operate instruments in the mainframe. It contains the following sections: • • • • • • Front Panel Features . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-1 Using Menus . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-2 Executing Commands . . . . . . . . . . . . . . . . . . . . . . . . . . . .
1 Using Menus You can access a System Instrument menu and a variety of other instrument menus (depending on installed instruments) from the front panel. These menus incorporate the most used functions but do not provide access to all of the instrument commands. If a particular function is not available from a menu, you can type the corresponding command string and execute it from the front panel. See “Executing Commands” later in this chapter for more information.
• Press Prev Menu to return to the previous menu within an instrument menu or escape from an input prompt. Press Select Instr to return to the Select an Instrument menu. Note that when you leave an instrument and return later, you return to the same menu location you were when you left. In addition, any other displayed information (instrument responses or commands being entered) will also be displayed when you return.
How to Reset the System GPIB Note: The RESET menu selection is equivalent to the DIAG:BOOT command which has the same effect as cycling power to the mainframe. Pressing Reset Instr from the System Instrument menu is equivalent to executing the *RST command which resets the System Instrument.
Using the Other Instrument Menus The instrument menus allow you to access the most-used instrument functions or to monitor an instrument (monitor mode) while it is being controlled from remote. We’ll use the Switchbox menu to show you how to use the instrument menus. Menus are available for many but not all instruments. See “Instrument Menus”, later in this chapter, for more information on a particular instrument’s menu.

How to Display Monitor Type, Description, or Reset Module How to Select Monitor Mode Using the Front Panel 2-7
Monitor Mode Monitor mode displays the status of an instrument while it is being controlled from remote. Monitor mode is useful for debugging programs. You can place an instrument in monitor mode using front panel menus, or by executing the DISP:MON:STAT ON command from the front panel or by remote. (Executing the remote DISP:MON:STAT ON command is the only way to assign the display/keyboard to an instrument from remote.
1 Executing Commands From the front panel, you can type and execute IEEE 488.2 Common Commands and SCPI Commands for the instrument presently selected by the Select an instrument menu. (However, you cannot execute a command when the display is requesting that you input information.) This is particularly useful for accessing functions not available in an instrument’s menu.
1 Key Descriptions This section explains the function of each of the front panel’s dedicated keys. If a key is not functional in a particular situation, pressing that key does nothing except to cause a beep. Users of the optional IBASIC interpreter should refer to their IBASIC manual set for additional editing functions. Menu Keys Selects the menu choice displayed directly above each key. Returns to the Select an instrument menu.
the cursor to the beginning of the line. Pressing CTRL followed by the left arrow key moves the cursor 4 character spaces to the left. Erases the character at the present cursor position (for user-entered data only). Erases the character to the left of the cursor (for user-entered data only). (Clear-to-end key.) Erases all characters from the present cursor position to the end of the input line (for user-entered data only).
1 In Case of Difficulty Problem: Problem Cause/Solution: Error -113 undefined header error occurs after entering data in response to a menu prompt. For some commands used by the menus, the data entered is appended to a command header. For example, if you enter "1" as the port number for a digital I/O module, the command used is DIG:HAND1:MODE NONE where HAND1 indicates the port number. If your entry was invalid or incorrect, error -113 occurs.

Chapter 3 Using the Display Terminal Interface Using this Chapter This chapter shows you how to use the Agilent E1300B and Agilent E1301B Mainframes’ Display Terminal Interface (terminal interface) to operate instruments in the mainframe. The terminal interface uses the built-in RS-232 and/or the optional Agilent E1324A Datacomm Module to provide all of the features of the Agilent E1301B’s front panel, plus comfortable keyboard position and full screen display.
1 Terminal Interface Features Figure 3-2 shows a typical terminal interface display with its function labels across the bottom of the screen. The first five function keys (f1 through f5) select instrument menu choices. Function keys f6 through f8 provide menu control and access to utility functions. The tutorials in this chapter show how to use most of the menu control and utility function keys.
1 Using Menus A System Instrument menu and a variety of other instrument menus (depending on installed instruments) are available from the terminal interface. These menus incorporate the most used functions but do not provide access to the complete functionality of an instrument. If a particular function is not available from a menu, you can type the corresponding Common Command or SCPI command string and execute it from the terminal interface.
If you make an incorrect entry in response to an input prompt, the bottom line of the Text Output Area will show an error message. When this happens, just select that menu choice again (f1 - f5 keys), re-type the correct information, and press Return. • Press PRV_MENU or ESC to return to the previous menu within an instrument menu or escape from an input prompt. Press SEL_INST to return to the Select an Instrument menu (see next item).
Using the System Instrument Menu The System Instrument menu allows you to: • • • • Set or read the system GPIB address Reset (reboot) the mainframe Display the logical addresses of installed instruments Display information about installed instruments How to Set or Read the System GPIB Address Enter new GPIB address, press Return (range= 1 through 30) SCPI command used: SYST:COMM:GPIB:ADDR < addr> Typical GPIB address SCPI command used: SYST:COMM:GPIB:ADDR? Using the Display Terminal Interface 3-5
How to Reset the System Press f1 to Reset Note: The RESET menu selection is equivalent to executing the DIAG:BOOT command which has the same effect as cycling the mainframe’s power. Pressing RST_INST from the System Instrument menu is the equivalent to sending the * RST command to the System Instrument.
How to Display Logical Addresses and Instrument Information Enter device’s logical address and press Return for individual instrument information, or just enter one space and Return, for information on all intruments. (In this case, 8 was entered) Logical address of selected device Instrument name GPIB secondary address Note: For a description of each field of the instrument information, see VXI:CONF:DLIS? in the SCPI Command Reference section.
Using the Other Instrument Menus The instrument menus allow you to access the most-used instrument functions or to monitor an instrument (monitor mode) while it is being controlled from remote. We’ll use the Switchbox menu to show you how to use the instrument menus. Menus are available for many but not all instruments. See “Instrument Menus”, later in this chapter, for more information on a particular instrument’s menu.
How to Open/Close Channels Switchbox instrument at logical address 32 (secondary address = 04) SCPI command used: OPEN < channel_list> Enter Channel List and press Return (e.g., 102 for channel 2 on card # 1) SCPI command used: CLOSE < channel_list> How to Scan Channels Press f2 to advance to the next channel in the Scan List (i.e. to trigger the instrument.) Enter Channel List and press Return (e.g.

How to Select Monitor Mode Enter Card Number or type AUTO and press Return SCPI commands used: DISP:MON:CARD < card_number> DISP:MON:STAT ON Monitor Mode Monitor mode displays the status of an instrument while it is being controlled from remote. Monitor mode is useful for debugging programs. You can place an instrument in monitor mode using terminal interface menus, or by executing the DISP:MON:STAT ON command from the terminal interface.
Note Enabling monitor mode slows instrument operations. If the timing or speed of instrument operations is critical (such as making multimeter readings at a precise time interval), you should not use monitor mode. Table 3-1 shows the status annunciators that may appear in the bottom line of the screen in monitor mode. Some instruments also have device-specific annunciators (see the plug-in module manual for more information). Table 3-1.
1 Executing Commands From the terminal interface, you can type and execute IEEE 488.2 Common Commands and SCPI Commands for the instrument presently selected by the Select an instrument menu. (However, you cannot execute a command when the screen is requesting that you input information.) This is particularly useful for accessing functions not available in an instrument’s menu.
1 General Key Descriptions This section explains the function of each of the terminal interface’s menu, menu control, and editing keys. If a key is not functional in a particular situation, pressing that key does nothing except to cause a beep. Menu and Menu Control Keys f1 UTILS through f5 SEL_INST PRV_MENU Label menu choices for corresponding function keys. Returns to the Select an instrument menu. Returns to the previous menu level within an instrument menu or escapes from an input prompt.
Erases the character to the left of the cursor (for user-entered data only). (Clear-to-end key.) Erases all characters from the present cursor position to the end of the input line (for user-entered data only). Selects the upper-case alphabetic characters or the character shown on the top half of a key. Sets all alphabetic keys to uppercase (capitals); does not affect the other keys. To return to lowercase, press Caps Lock again.
1 Using Supported Terminals The Supported Terminals The Display Terminal Interface supports several popular terminal brands and models. This chapter will show you how to access all of the terminal interface functions described previously using your supported terminal. The following list names the supported terminals and shows where to go for more information. If your terminal isn’t named in this list, see “Using Other Terminals” in the next section. • • • • HP 700/92 . . . . . . . . . . . . . . . . . . .
Using the HP 700/22 VT100® Key Map Selecting VT100® Mode The HP 700/22 terminal emulates the DEC® VT100® or VT220® terminals. Some functions of the Display Terminal Interface have been mapped into keys with other labels. A keyboard map is provided for each of the emulation models. Use these keyboard maps to help locate the terminal interface functions. The symbols shown in the upper left corner of key each are now mapped with the function labeled in the center of each key.
VT220® Key Map Note The function keys that are normally labeled f6 through f14 are now labeled: Because the HP 700/22 keyboard has nine function keys in the center of the keyboard, f4 is mapped twice The symbols shown in the upper left corner of key each are now mapped with the function labeled in the center of each key.
Using the WYSE WY-30 With the WYSE WY-30 terminal, some functions of the Display Terminal Interface have been assigned to keys with other labels. Use this keyboard map to help locate these functions. The symbols shown in the upper left corner of key each are now mapped with the function labeled in the center of each key. Where two function key labels are shown, the one following the "/" character is accessed by pressing and holding the CTRL key while pressing the desired function key (e.g.
What “Not Supported” Means Strictly speaking, a terminal is not supported if it has not been rigorously tested with the Display Terminal Interface. There are several HP terminals which may be compatible with the terminal interface. Terminals such as the DEC® VT100® , DEC® VT220® , and WYSE ® WY-50, or emulations of these may also work properly with the terminal interface. If you have one of these terminals, try it. Here is a list of terminals you should try.
If you now see the “Select an instrument” menu labels: Go to the beginning of this chapter and try the menus. or Turn the mainframe off and then on again. Using a Terminal Without Menus You can still control instruments installed in your mainframe without using the terminal interface menus. In this case you will send Common Commands and SCPI commands to your instruments by typing them on your terminal keyboard, or through a computer interface.
To get a list of the logical addresses used in your mainframe, send the SCPI command VXI:CONF:DLAD? to the System Instrument. Then to determine what instrument is at each logical address, send the command VXI:CONF:DLIS? n for each logical address in the list (where n is a logical address). Returning to the “Select an Instrument” Prompt To return to the “Select an instrument” prompt, press and hold the CTRL key then press D.
1 In Case of Difficulty Problem: Problem Cause/Solution: Error -113 undefined header error occurs after entering data in response to a menu prompt. For some commands used by the menus, the data entered is appended to a command header. For example, if you enter "1" as the port number for a digital I/O module, the command used is DIG:HAND1:MODE NONE where HAND1 indicates the port number. If your entry was invalid or incorrect, error -113 occurs.

Chapter 4 Using the Mainframe Using this Chapter This chapter shows how to use the mainframe’s Pacer function, how to change the primary GPIB address, and how to synchronize internal and external instruments using the mainframe’s Event In and Trigger Out ports. This chapter also discusses how mainframe memory is used by installed instruments. Where possible, examples show only the command string sent to the instrument (no information about a computer language or interface is shown).
• SOUR:PULS:COUN sets the number of Pacer cycles. Specify from 1 to 8388607 cycles or specify INF for a continuous output. • SOUR:PULS:PER sets the period of each Pacer cycle. You can specify periods from 500ns to 8.3 seconds. • TRIG:SOUR sets the trigger source. The Pacer signal is output whenever the trigger event occurs (specified by the TRIG:SOUR command) and the INIT:IMM command has been executed.
Figure 4-2. Pacer Trigger States 1 Changing the Primary GPIB Address You can set the mainframe’s primary GPIB address to any integer value between 0 and 30. The address is set to 9 at the factory. (See Chapter 2 for instructions on setting/reading the GPIB address from the front panel.) The following command sets the mainframe’s primary GPIB address to 12.
Example: Synchronizing an Internal Instrument to an External Instrument This example uses the mainframe’s Trig Out and Event In ports to synchronize an external multimeter to a multiplexer installed in the mainframe. Connections are shown in Figure 4-3. The multimeter’s Voltmeter Complete port outputs a pulse whenever the multimeter has finished a reading. The multimeter’s External Trigger port allows the multimeter to be triggered by a negative going TTL pulse.
multimeter to an internal multiplexer. Connections are shown in Figure 4-4. This method synchronizes the computer to the instruments and relies on the computer to enter each reading and advance to the next channel in the scan list. The sequence of operation is: 1. INIT (line 50) closes channel number 100. 2. The channel closure causes a pulse on Trig Out which triggers the multimeter to take a reading. 3. When the reading is complete it is sent to the computer (lines 60 to 80). 4.
Figure 4-4. Synchronizing Internal/External Instruments and Computer 1 Mainframe Data Memory When power is applied or the system rebooted (DIAG:BOOT command), mainframe memory is automatically configured to provide a predefined amount of memory for any installed instruments that require memory space. For example, each multimeter instrument within the mainframe is allocated enough memory to store 100 readings. Mainframe memory is also automatically re-allocated upon demand while programming.
Example: Storing and Retrieving Data From Mainframe Memory. This example shows how to use mainframe memory to store 15 readings made using an Agilent E1326A Multimeter. After the readings are stored, they are retrieved by the computer and displayed.
address. You will then know the starting address , and (from the …NRAM:CRE < size> command) the length of the NRAM segment. Example: Allocating an NRAM segment and locating it. This example shows how to allocate a small 128 byte NRAM segment. In addition, it shows how to determine the starting address of that segment.
Using :DOWNload and :UPload? to Access Data Caution Data Formats for :DOWNload The command DIAG:DOWNload < address> ,< data_block> is used to store data into the NRAM segment. The command DIAG:UPLoad? < address> ,< byte_count> is used to retrieve data from the NRAM segment. The address parameter in …DOWNload and …UPLoad? can specify any address within the capability of the System Instrument’s control processor.
Example: Storing and Retrieving data using DOWNload and UPLoad.
Chapter 5 Downloading Device Drivers About this Chapter This chapter describes the procedure for using downloadable device drivers with the Agilent E1405 Command Module. This functionality was added so that SCPI capability for new register based devices could be added to the Command Module without having to update an internal set of ROMs. This chapter contains the following sections: • • • • • • • • • • About this Chapter. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
GPIB bus GPIB bus GPIB bus GPIB Figure 5-1.
1 Memory Configuration Before attempting to download any device drivers you should understand how memory is affected when you specify a size for one or more types of RAM. There are three types of RAM that you can allocate in the mainframe: • RAM disk (RDISK) • Non-volatile RAM (NRAM) • Driver RAM (DRAM) Figure 5-2 shows the positioning of these areas in memory. User Non-volatile RAM and RAM Disk both occupy higher memory addresses than the Driver RAM.
1 Download Program Configuration If you will not be using the default configurations for downloading, you will need to edit the configuration file to match your system configuration. If the default values shown below are correct for your setup, you can proceed to the appropriate downloading instructions. The configuration defaults for MS-DOS systems are: • • • • • • • • Download program searches for drivers in current directory. Execution Log is OFF (log to screen only).
specify a file name here, the driver downloader will log to the screen and to the specified file. DRIVER FILE = specifies the driver file or files to download. The default is to download all device driver files found in the directory specified by DIRECTORY = . If the driver downloader finds one line in this format, it will assume that you are specifying entries and will only download the listed entries. This configuration item can have multiple lines.
1 Downloading Drivers in MS-DOS Systems The device driver download program VXIDLD.EXE provided on the disk with the driver files for use with an RS-232 interface must be run from MS-DOS. It will set up the the required device driver memory and any other memory partitions defined in the configuration file, reboot the system, and download the device driver.
1 Downloading Drivers in GPIB Systems with IBASIC NOTE The device driver download program AUTOST provided on the disk with the driver files for use with GPIB must be run from IBASIC (Instrument Basic). It will set up the the required device driver memory and any other memory partitions defined in the configuration file, reboot the system, and download the device driver. This program will issue a warning and abort if any errors are encountered.
1 Downloading Drivers in GPIB Systems with BASIC The device driver download program VXIDLD_GET provided on the disk with the driver files for use with GPIB must be run from an BASIC other than IBASIC. It will set up the the required device driver memory and any other memory partitions defined in the configuration file, reboot the system, and download the device driver.
1 Downloading Multiple Drivers The driver downloader software automatically checks for the existence of other drivers when it is run. If there are device drivers present, it will abort the process and inform you that you must first clear the other device drivers out of the mainframe and then download all of the required drivers at once.
1 Manually Downloading a Driverdown manual Preparing Memory for Manual Downloading Download programs are supplied for use with the system setups described earlier in this chapter. If you have a system setup that does not allow the use of one of the supplied download programs (for instance, if you are using a Macintosh® computer), you will need to manually download the driver. The details of this process will be different for different system setups, but the basic procedures are outlined below.
Manually Downloading Over GPIB Manually downloading a driver over GPIB is fairly straightforward. This discussion assumes that the downloadable device driver has been supplied by Agilent. Drivers supplied by Agilent are formatted so that you just need to transfer the driver to command module memory. You must also have the driver on media that is accessible to the host computer that will be controlling the download.
If you are going to use any other setting, you must set up the appropriate settings in the System Instrument using the following commands COMM:SER[n]:REC:BAUD < rate> COMM:SER[n]:REC:SBITS < bits> DIAG:COMM STOR NOTE Pacing the Data sets BAUD rate sets number of stop bits saves settings so they will be kept through a reboot.
handshake mode is enabled, the System Instrument will not transmit characters when either the CTS (Clear to Send) or the DSR (Data Set Ready) lines are not asserted. This acts to pace the System Instrument output. NOTE The E1405 Command Module RS-232 interface is implemented as a DTE (Data Terminating Equipment). Since most computer RS-232 interfaces are also implemented as DTEs, a cable that does line swapping (null modem cable) is usually used to connect the computer to the instrument.
Transmitting Using a CAT Command On HP-UX systems you can use the cat command to transfer the device driver. The appropriate device file must exist. All shell commands are assumed to be executed from either the /bin/sh or /bin/ksh shell. 1. Start a process that opens the device file to be used. This process should keep the device file open long enough for the transfer to begin. This step is done so that the following command to set the device file configurations will remain in effect for the transfer.

Chapter 6 Controlling Instruments Using GPIB About this Chapter This chapter shows how to control instruments in the mainframe from an external computer using IEEE 488.2 Common Commands and the GPIB interface. This includes how to monitor instrument status, interrupt the computer, and synchronize one or more instruments to an external computer. Command references for the supported IEEE 488.2 Common Commands and IEEE 488.2 GPIB Messages are located near the end of this chapter.
2 Status System Structure The instrument status structure monitors important events for an instrument such as when an error occurs or when a reading is available.
The Status Byte Register As shown in Figure 4-1, the Status Byte register is the highest-level register in the status structure. This register contains bits which summarize information from the other status groups. NOTE The bits in the other status group registers must be specifically enabled to be reported in the Status Byte register. Refer to "Unmasking Standard Event Status Bits" (later in this chapter) for more information.
Table 4-1 shows each of the Status Byte register bits and describes the event that will set each bit. Table 4-1. Status Byte Register Reading the Status Byte Register Bit Number Decimal Weight 0 1 Instrument Specific (not used by most instruments) 1 2 Instrument Specific (not used by most instruments) 2 4 Instrument Specific (not used by most instruments) 3 8 Questionable Data Status Group Summary Bit.
The following program reads the system instrument’s Status Byte register using the GPIB Serial Poll command. 10 P= SPOLL(70900) 20 PRINT P 30 END Service Request Enable Register Read Status Byte Register using Serial Poll, place weighted sum in P Print weighted sum The Service Request Enable register is used to "unmask" bits in the Status Byte register. When an unmasked Status Byte register bit is set to ’1’, a service request is sent to the computer over GPIB.
Standard Event Status Register NOTE The Standard Event Status Register in the Standard Event status group monitors the instrument status events shown in Table 4-2. When one of these events occurs, it sets a corresponding bit in the Standard Event Status Register. The Standard Event Status Register bits are not reported in the Status Byte Register unless unmasked by the Standard Event Status Enable Register. Refer to the section "Unmasking Standard Event Status Bits" for more information. Table 4-2.
unmasked, an GPIB service request (SRQ) will be generated. ("Interrupting the External Computer", later in this chapter contains an example program which demonstrates this sequence). Note that the Standard Event Status Register bits that are not unmasked still respond to their corresponding conditions. They do not, however, set bit 5 in the Status Byte Register.
Table 4-3.
Bits in the Operation Status Group Event register which are set can be determined with the command: STATus:OPERation:EVENt? This command returns the decimal weighted sum of the set bit(s).
SUB Intr_resp B= SPOLL(70900) OUTPUT 70900; "STAT:OPER:EVEN?" ENTER 70900; E OUTPUT 70900; "DIAG:INTR:RESP?" ENTER 70900; R . . . SUBEND 1 Clearing Status The *CLS command clears all status registers (Standard Event Status Register, Standard Operation Status Event Register, Questionable Data Status Event Register) and the error queue for an instrument. This clears the corresponding summary bits (bits 3, 5, & 7) and the instrument-specific bits (bits 0, 1, & 2) in the Status Byte Register.
Example: Interrupting when an Error Occurs This program shows how to interrupt an external computer whenever an error occurs for the instrument being programmed which, in this example, is a multimeter at secondary address 03.
1 Synchronizing an External Computer and Instruments The *OPC? and *OPC commands (operation complete commands) allow you to maintain synchronization between an external computer and an instrument. The *OPC? query places an ASCII character 1 into the instrument’s output queue when all pending instrument operations are finished. By requiring the computer to read this response before continuing program execution, you can ensure synchronization between one or more instruments and an external computer.
Example: Synchronizing an External Computer and Two Instruments using the * OPC command. This example uses the *OPC command and serial poll to synchronize an external computer and two instruments (DAC at secondary address 09; Scanning Voltmeter at secondary address 03). The advantage to using this method over *OPC? query method is that the computer can do other operations while it is waiting for the instrument(s) to complete operations.

Chapter 7 System Instrument Command Reference About This Chapter This chapter describes the Standard Commands for Programmable Instruments (SCPI) command set and the IEEE 488.2 Common Commands for the System Instrument. The System Instrument is part of the Agilent E1300/E1301 Mainframe’s internal control processor and is therefore always present in a Mainframe. This chapter contains the following sections: • • • • • Command Types. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Command Separator A colon (:) always separates one command from the next lower level command as shown below: ROUTe:SCAN:MODE? Colons separate the root command from the second level command (ROUTe:SCAN) and the second level from the third level (SCAN:MODE?). Abbreviated Commands The command syntax shows most commands as a mixture of upper and lower case letters. The upper case letters indicate the abbreviated spelling for the command. For shorter program lines, send the abbreviated form.
(e.g., 123, 123E2, -123, -1.23E2, .123, 1.23E-2, 1.23000E- 01). Special cases include MIN, MAX, and INFinity. The Comments section within the Command Reference will state whether a numeric parameter can also be specified in hex, octal, and/or binary. # H7B, # Q173, # B1111011 • Boolean parameters represent a single binary condition that is either true or false (e.g., ON, OFF, 1, 0). Any non-zero value is considered true. Discreet parameters select from a finite number of values.
ABORt 1 SCPI Command Reference This section describes the SCPI commands for the System Instrument. Commands are listed alphabetically by subsystem and also within each subsystem. A command guide is printed in the top margin of each page. The guide indicates the first command listed on that page. ABORt The ABORT subsystem is a part of the System Instrument’s trigger system. ABORT resets the trigger system from its Wait For Trigger state to its Idle state and aborts any pacer pulse train in progress.
DIAGnostic DIAGnostic Subsystem Syntax The DIAGnostic subsystem allows control over the System Instrument’s internal processor system (:BOOT, and :INTerrupt), the allocation and contents of User RAM, and, disc volume RAM (:NRAM, and :RDISk), and allocation of the built-in serial interface (:COMM:SER:OWNer).

This method of identifying registers follows the VXIbus standard format.
1 Common Command Reference This section describes the IEEE-488.2 Common Commands that can be used to program instruments in the mainframe. Commands are listed by command groups in the summary table below, and alphabetically in the rest of this section. Examples are shown when the command has parameters or returns a response; otherwise the command string is as shown in the headings in this section. For additional information on any Common Commands, refer to the IEEE Standard 488.
* CLS * DMC < name_string> , < command_block> Clear Status Command. The *CLS command clears all status registers (Standard Event Status Register, Standard Operation Event Status Register, Questionable Data Event Register) and the error queue for an instrument. This clears the corresponding summary bits (bits 3, 5, & 7) and the instrument-specific bits (bits 0, 1, & 2) in the Status Byte Register.
* ESE? Example * ESR? Example Standard Event Status Enable Query. Returns the weighted sum of all enabled (unmasked) bits in the Standard Event Status Register. 10 OUTPUT 70900;"* ESE?" 20 ENTER 70900;A 30 PRINT A 40 END Standard Event Status Register Query. Returns the weighted sum of all set bits in the Standard Event Status Register. After reading the register, *ESR? clears the register.
* IDN? Identity. Returns the device identity. The response consists of the following four fields (fields are separated by commas): • • • • Manufacturer Model Number Serial Number (returns 0 if not available) Firmware Revision (returns 0 if not available) The *IDN? command returns the following command string for the E1301B: AGILENT,E1301B,0,A,07.00 This command will return the following string for the E1300B: AGILENT,E1300B,0,A,07.
The System Instrument no longer implements the *LRN? command. Attempting to have the System Instrument execute this command will generate an error -113 “Undefined header”. NOTE * OPC Operation Complete. Causes an instrument to set bit 0 (Operation Complete Message) in the Standard Event Status Register when all pending operations have been completed.
* RCL < state number> Recall stored state. Recalls a stored state from memory and configures the instrument to that state. States are stored using the *SAV command. Example * RMC < name_string> OUTPUT 70900;"* RCL 4" Recalls instrument state number 4 Remove Individual Macro Command. Purges an individual macro identified by the name_string parameter.
* SRE? Example Status Register Enable Query. Returns the weighted sum of all enabled (unmasked) events (those enabled to assert SRQ) in the Status Byte Register. 10 OUTPUT 70900;"* SRE?" 20 ENTER 70900;A 30 PRINT A 40 END * STB? Comments Example Sends Status Register Enable query Places response in variable Prints response Status Byte Register Query. Returns the weighted sum of all set bits in the Status Byte Register.
1 GPIB Message Reference Go To Local (GTL) Comments Examples This section describes IEEE-488.1 defined messages and their affect on instruments installed in the mainframe. The examples shown are specifically for HP 9000 Series 200/300 computers using BASIC language. Any IEEE-488 controller can send these messages; however, the syntax may be different from that shown here. Places an instrument in local state.
Device Clear (DCL) or Selected Device Clear (SDC) DCL clears all instruments in the mainframe. SDC clears a specific instrument. The purpose of DCL or SDC is to prepare one or more instruments to receive and execute commands (usually *RST). DCL or SDC do the following to each instrument: • Clear the input buffer and output queue. • Reset the command parser. • Disable any operation that would prevent *RST from being executed. • Disable the Operation Complete and Operation Complete Query modes.
Remote Sets the GPIB remote enable line (REN) true which places an instrument in the remote state. Comments • The REMOTE 709ss (ss = secondary address) command places the instrument in the remote state. The REMOTE 7 command, does not, by itself, place the instrument in the remote state. After sending the REMOTE 7 command, the instrument will only go into the remote state when it receives its listen address. • In most cases, you will only need the REMOTE command after using the LOCAL command.

1 Start-up Error Messages Start-up errors are most often generated just after the mainframe is powered-up or re-booted (DIAG:BOOT command). If you have an Agilent E1301B, or an Agilent E1300B with a terminal connected to the Display Terminal Interface (built-in RS-232 only), you can read these errors on the front panel or terminal. If you have an Agilent E1300B and no terminal, then you must access this error information by sending the VXI:CONF:DLIS? command over GPIB.

1 Configuring a Terminal for the Mainframe Starting with Default Mainframe Settings We’ll first set the terminal’s serial communication parameters to match the mainframe’s default settings. If the mainframe is new and its factory default values are still set, the terminal will be ready to use. If the settings have been changed and you don’t know what they are (Agilent E1300 with no front panel), you will restore them to their default values.
Trying it Turn on the mainframe while watching the terminal’s display. After the mainframe finishes its self-test, the terminal should display "Select an instrument". If not, the mainframe’s communication parameters are not set to the default values. Go back to “Restoring the Default Configuration”. 1 Configuring the Mainframe with Menus After you have your terminal communicating with your mainframe at the default settings you may want to change to settings which are better for your installation.
How to Use the Serial Interface Menus Press READ to find out the current setting Press SET to change the current setting Each SET Menu will have two or more choices Enter Card Number press Return (0 for built-in, 1-7 for a plug-in) Read the BAUD rate Enter Card Number press Return (0 for built-in, 1-7 for a plug-in) The setting is now in volatile RAM storeage. See the “How to Store Interface Settings” Menu Chart for non-volatile storage which maintains settings through power cycles.
How to Store the Serial Interface Configuration Enter Card Number press Return. Card Number 0 for built-in stores settings into non_volatile RAM.
