Introduction For controlling the Agilent 81133A/81134A remotely, the instrument provides three different interfaces: • GPIB Using the GPIB connector, the instrument can be controlled from a PC or a UNIX Workstation. • LAN Using the LAN connector, the instrument can be connected to a local area network and can be programmed from a PC. • USB USB is the replacement for GPIB when used on the bench. The language is the same as with GPIB.
Introduction 10 Agilent 81133A/81134A Pulse Generator Programming Guide, March 2007
Connecting to the Pulse/Pattern Generator for Remote Programming The following sections show how to establish the connection between your control PC and the instrument through the available remote interfaces. Connecting to the Instrument via GPIB You can use GPIB connections only for controlling the instrument by means of SCPI commands. To connect to the instrument via GPIB you have to: • Use GPIB cables to connect the instrument to the test environment. • Specify the instrument’s GPIB address.
Connecting to the Pulse/Pattern Generator for Remote Programming Connecting to the Instrument via GPIB Example for Connecting via GPIB The following code example shows how to use the VISA library to connect to the instrument via GPIB. This example queries a GPIB device for an identification string and prints the results. Implementation #include #include
Connecting to the Instrument via LAN Connecting to the Pulse/Pattern Generator for Remote Programming Connecting to the Instrument via LAN For connecting over the LAN, you would do have the following: • Connect the instrument to the LAN physically. • Configure the Agilent IO Libraries on the remote machine. • On the user interface, either specify the LAN address or—if a DHCP server is available—enable the DHCP. The DHCP will automatically set up the LAN connection.
Connecting to the Pulse/Pattern Generator for Remote Programming Connecting to the Instrument via LAN 3 Run IO Config. The IO Config utility (iocfg32.exe) can be found at (default location): C:\Program Files\Agilent\IO Libraries Suite\bin Note that you can also open the IO Config from the Agilent IO Libraries Control icon in the task bar. 4 Edit “inst0” to “lan0”. Select “TCPIP Lan”, then click Edit. This will bring up the list of TCPIP devices already configured.
Connecting to the Instrument via USB Connecting to the Pulse/Pattern Generator for Remote Programming viClose (defaultRM); } Connecting to the Instrument via USB NOTE The control PC must have USB capability for USB connections (Windows NT is not supported). For connecting over the USB, please refer to the Help delivered with the USB driver.

Parameter Numeric *RST value – Specified limits 0 … 32767 :STATus:QUEStionable:MONotony:NTRansition Syntax Form Description NOTE :STAT:QUES:MON:NTR[?] Set & Query Sets or queries the negative- transition register in the QUEStionable:MONotony status group.
SYSTem Commands SCPI Commands Reference NOTE The Agilent 81133A/81134A Pulse Generator does not use the transition registers of the QUEStionable:MONotony status group, therefore, this command is redundant.
SCPI Commands Reference SYSTem Commands Command Parameter Description :HADDRess String Set/read host LAN address for the instrument. This setting is important for FTP transfer :NAME alphanumeric Sets the LAN name for the instrument :DHCP 1|0|ON|OFF Enables/disables DHCP configuration Numeric Sets/reads GPIB bus No.
SYSTem Commands SCPI Commands Reference :SYSTem:ERRor? Syntax Form Description :SYST:ERR? Query This command is used to read the Agilent 81133A/81134A Pulse Generator error queue. The Agilent 81133A/81134A Pulse Generator error queue can store up to 32 error codes on a firstin- first- out basis. When you read the error queue, the error number and associated message are put into the instrument’s output buffer. If the error queue is empty, the value 0 is returned, meaning No Error.
SCPI Commands Reference SYSTem Commands :SYSTem:SET Syntax :SYST:SET[?] Form Set & Query Description In query form, the command reads a block of data containing the instrument’s complete setup. The setup information includes all parameter and mode settings, but does not include the contents of the instrument setting memories, the status group registers or the :DISPlay[:WINDow][:STATe]. The data is in a binary format, not ASCII, and cannot be edited.

TRIGger Commands SCPI Commands Reference :TRIGger:SOURce Syntax Form Description :TRIG:SOUR[?] Set & Query This command is used to switch the timebase mode between Internal (IMMediate) and External (EXTernal). With :TRIGger:SOURce IMMediate (internal timebase) the frequency (or period) is controlled with the [:SOURce]:FREQuency (or [:SOURce][:PULSe]:PERiod) command.
SCPI Commands Reference TRIGger Commands – EDIRect Allows you to vary the frequency of the external clock signal in the range of one octave. Range switching occurs at the following frequency values: • 1680 MHz • 840 MHz • 420 MHz • 210 MHz • 105 MHz • 51.5 MHz • 25.75 MHz These values are based on 1680 MHz, subject to the frequency divider. *RST value Example IMMediate Select the external timebase mode.
TRIGger Commands SCPI Commands Reference :TRIGger:TERM:STATE[?] Syntax Form Description :TRIG:TERM:STATE[?] Set & Query Defines whether the external clock input connector (Clock In) is AC or DC terminated. Parameter ON|OFF where ON = DC and OFF = AC terminated. *RST value OFF Example Set the coupling of the external clock input connector to DC.

Troubleshooting This chapter provides basic troubleshooting tips that you can use if the instrument is not performing as expected. Error Generated The instrument generates error messages as follows: -221:Settings conflict:String describing the error The string describing the error could be one of the following: • "divider of channel [1|2] leads to a frequency below minimum frequency" This occurs if the frequency below one of the channels is set below the minimum (15 MHz).
Troubleshooting • "delay of channel [1|2] below minimum" May happen: – If the frequency is decreased and the channel is in phase mode, or – if the square mode is switched from square to another mode, or – if clock mode is switched from internal/external direct to a none direct mode.
Troubleshooting – If the trigger amplitude is increased, or – if the offset is decreased. • "low level of channel [1|2] is below minimum" May happen: – If the channel amplitude is increased, or – if the offset is decreased. • "high level of trigger exceeds maximum" May happen: – If the trigger amplitude is increased, or – if the offset is increased. • "high level of channel [1|2] exceeds maximum" May happen: – If the channel amplitude is increased, or – if the offset is increased.
