Page 97 Chapter 4 Features and Functions Digital I/O Operation • Remote Interface Operation: Set the flow control parameters using the following SCPI commands. These examples assume a digital I/O module is installed in slot 4. ! Set the flow control mode to SOURce:DIGital:MODE 4,1 Mode 1.
Page 98 Chapter 4 Features and Functions Digital I/O Operation About Flow Control Modes (Handshake) Five flow control modes are available for Digital I/O operations. Some modes use one or more of the three flow control lines: I/O Direction, PFLG, and PCTL. Select the flow control you need for your digital input/ output applications.
Page 99 Chapter 4 Features and Functions Digital I/O Operation Static Mode #1 Static Mode #1 is the default mode. In this mode, data is transferred statically, there is no read or write strobe pulses or handshaking. The I/O Direction line is active and indicates direction of transfer. This is shown in the following timing diagrams.
Page 100 Chapter 4 Features and Functions Digital I/O Operation Read or Write and Strobe Mode #3 In this mode, the I/O direction line is still used to indicate direction of transfer (input or output) but the PCTL (Peripheral control) line is used to strobe the data.
Page 101 Chapter 4 Features and Functions Digital I/O Operation Read and Write Strobe Mode #4 Read and Write Strobe Mode #4 uses the I/O direction line as a Strobe pulse to indicate writing operations. The PCTL line is used to indicate Read operations.
Page 102 Chapter 4 Features and Functions Digital I/O Operation Full Handshake Mode #5 Handshake Mode #5 provides a complete two wire handshake with a data direction line. During write operations, the PCTL line indicates that output data is valid; during read operations, it indicates that the digital I/O module (i.e.

Page 147: State Storage Commands
Chapter 5 Remote Interface Reference State Storage Commands State Storage Commands The 3499A/B/C provides the capability to store setups, and then recall them to put the instrument back into a known configuration. The operation of state storage is dependent upon the instrument’s firmware revision.
Page 148: Status System Commands
Status System Commands This section describes the structure of the SCPI status system for the Agilent 3499A/B/C and describes the commands used to work with the status system. The status system records various conditions, events, and states of the instrument in three register groups. The three groups are shown below.
Page 149 Chapter 5 Remote Interface Reference Status System Commands Each register group has one or more low-level registers. These low-level registers are called condition, event, or enable registers and control the action of specific bits in the registers. You read or write to the registers using binary-weighted decimal numbers.
Page 150 Chapter 5 Remote Interface Reference Status System Commands The Operation Status Register The 3499A/B/C uses only three of the bits in this 16-bit register. Bit 0 indicates the instrument is waiting in the trigger layer (the next trigger event will advance the scan list). Bit 1 indicates the instrument is waiting in the arm layer (the next trigger event will move the instrument to the trigger layer).
Page 151 Chapter 5 Remote Interface Reference Status System Commands The Standard Event Register The Standard Event Register reports instrument events, errors, and the *OPC command. The Standard Event Register reports through the ESB bit (bit 5) in the Status Byte Register. *ESR? This query returns a decimal weighted value of the event register.
Page 152 Chapter 5 Remote Interface Reference Status System Commands The Status Byte Register The Status Byte Register reports conditions from the other register groups. Data in the 3499A/B/C output buffer is reported on the MAV bit (bit 4). If an event is cleared in one of the other registers, it is also cleared in the Status Byte register.
Page 153: System Information Commands
Chapter 5 Remote Interface Reference System Information Commands System Information Commands These commands are used to obtain system-level information. *IDN? This IEEE488.2 Common Command queries the instrument for the identification string. The returned string will contain the manufacturer identification, the model number, the serial number, and the firmware revision.

Page 156: System-Level Control Commands
Chapter 5 Remote Interface Reference System-Level Control Commands System-Level Control Commands These commands allow you to synchronize the instrument to the bus controller, reset the instrument, and control the display. *OPC *OPC? This command and query are used to synchronize the instrument with the bus controller.
Page 157 Chapter 5 Remote Interface Reference System-Level Control Commands *TST? This query begins a self-test and returns a code to indicate the test status. One of the following codes can be returned: Returned Meaning Value all tests have passed. ROM test failed. GPIB test failed.
Page 158 Chapter 5 Remote Interface Reference System-Level Control Commands DIAGnostic :DISPlay[:INFOrmation] <message> :DISPlay:STATe <0|1|OFF|ON> :DISPlay:STATe? These commands control the front-panel display. The DIAGnostic:DISPlay:INFOrmation command is used to write messages to the display. The message parameter is a string that can contain up to 13 characters. You can enter the string in lower case characters, but the display only shows upper case characters.
Page 159 Chapter 5 Remote Interface Reference System-Level Control Commands DIAGnostic :MONitor <slot>|<channel>|<port>|-1 :MONitor? The DIAGnostic:MONitor command enables the monitor mode for a plug-in module, channel, or port on the specified module. Send the -1 value to disable the monitor mode. Only one slot, one channel, or one port can be monitored each time.
Page 160: Rs-232 Commands
Chapter 5 Remote Interface Reference RS-232 Commands RS-232 Commands These commands only apply to operations with the RS-232 interface. SYSTem :LOCal :REMote :RWLock The SYSTem:LOCal command sets the local mode for RS-232 operation. All keys on the front-panel are fully functional in this mode. The SYSTem:REMote command sets the instrument to the remote mode for RS-232 operation.
Page 161: About The Scpi Language
Chapter 5 Remote Interface Reference About the SCPI Language About the SCPI Language Common Commands The IEEE 488.2 standard defines the common commands that perform functions such as reset, self-test, status byte query, and so on. Common commands are four or five characters in length, always begin with an asterisk (*), and may include one or more parameters.
Page 162 Chapter 5 Remote Interface Reference About the SCPI Language 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.
Page 163 Chapter 5 Remote Interface Reference About the SCPI Language Parameters These are parameter types used with the SCPI language: Parameter Type Description Numeric Accepts all commonly used decimal representations of number including optional signs, decimal points, and scientific notation. 123, 123E2, -123, -1.23E2, .123, 1.23E-2, 1.23000E-01.

Page 272: Protection Networks
Chapter 7 Plug-in Modules Protection Networks Protection Networks This information applies specifically to the N2267A (page 206) and 44471A (page 236) multiplexer modules. These multiplexers have provisions built in to allow you to add custom protection networks. This information is general and may be used to help you design other relay protection circuits.
Page 273 Chapter 7 Plug-in Modules Protection Networks In designing RC protection networks, the protection resistor, R , is selected as a compromise between two values. The minimum value of R is determined by the maximum acceptable relay contact current (Io). The maximum allowable relay current (Io) is 2 amps ac rms or 2 amps dc.
Page 274 Chapter 7 Plug-in Modules Protection Networks For example, we will determine the typical values for an RC protection network where the load is a small ac motor running on the 120 V ac line (170 V peak). This motor draws a maximum of 2 amps. Using Equation 1 we can find the minimum value for R = V/Io = 170/2 = 85 Ω...
