5 GPIB Reference Introduction This chapter provides the information needed to control the 4339B through the GPIB interface in the GPIB Remote mode. GPIB Command Reference Status Reporting Trigger System Data Transfer Format GPIB Commands The 4339B's GPIB commands are compatible with the Standard Commands for Programmable Instruments (ACPI ). SCPI is the instrument command language for controlling instruments that go beyond IEEE 488.
PAGE 150
GPIB Commands 4339B Colon (:) When a colon is placed between two command mnemonics, the colon moves the current path down one level on the command tree. When the colon is the rst character of a command, it speci es the following command mnemonic is a root-level command. Semicolon (;) A semicolon separates two commands in the same message without changing the current path. Figure 5-1 shows examples of how to use the colon and semicolon to navigate e ciently through the command tree.
PAGE 151
4339B GPIB Commands Case Letter cases (upper and lower) are ignored. Program Message Terminator Program message must be ended with one of the three program message terminators, , <^END>, or <^END>. <^END> means that End Of Identify (EOI) is asserted on the GPIB interface at the same time the preceding data byte is sent. For example, the HP BASIC OUTPUT statement is automatically sent after the last data byte.
PAGE 152
GPIB Commands 4339B The subsystem commands use extended numeric parameters. Extended numeric parameters accept all numeric parameter values and other special values, for instance, MAXimum, MINimum or UP, DOWN. The special values available are described in the command's reference description. Query response of is always a numeric value in (integer) or ( oating point) format.
PAGE 153
4339B GPIB Commands Query and Response Message Syntax All subsystem commands can be queried except for the commands described as \no query" in the command reference. To send a query message, add a question mark, ? after the last command mnemonic. :AVER:COUN? A response message may contain both commas and semicolons as separators. When a single query command returns multiple values, a comma is used to separate each data item.
PAGE 154
Command Reference 4339B Command Reference Notations In this chapter, each subsystem is documented using the tabular format instead of the command tree as follows. The following conventions and de nitions are used to describe GPIB operation.

Lower nodes in the hierarchy are indented one position to the right.
PAGE 155
4339B ABORt Command ABORt Command :ABORt Resets the trigger system and places all trigger sequences in Idle state. Any actions related to the trigger system that are in progress, such as acquiring a measurement, are aborted immediately. The execution of an :ABORt command will set any pending operation ag to FALSE, for example ags that were set by the initiation of the trigger system. Refer to \Trigger System". Unlike *RST, :ABORt does not alter the settings programmed by other commands.

4339B Trigger System Trigger System This section provides information about the trigger system of the 4339B. SCPI de nes a common trigger model for several types of instruments. The trigger system allows you to have speci c control of your measurements. Information on the trigger system requires more technical expertise than most other topics covered in this chapter. But you can avoid having to learn the information in this section by using the :INITiate commands to make your measurements.
PAGE 194
Trigger System 4339B Idle State The trigger system remains in the idle state until it is initiated by :INITiate[:IMMediate] or :INITiate:CONTinuous ON commands. Once one of these conditions is satis ed, the trigger system exits downward to the initiate state. Note that *RST sets INITiate:CONTinuous OFF. Initiate State If the trigger system is on a downward path, it travels directly through the initiate state without restrictions.

4339B High Capacitance DUT Measurement High Capacitance DUT Measurement When the 4339B measures a DUT that has high capacitance, AC noise creates major instability factors in the measurement because capacitance is sensitive to AC noise. If you want to measure the resistance of a high-capacitance DUT maintaining more than 10 % of S/N (Signal/Noise) ratio, the maximum capacitance of the DUT's for each measurement range are listed in Table 7-1.

B Handler Interface Installation This appendix provides the electrical characteristics of the handler interface signals, and how to set up the handler interface board. Electrical Characteristics Output Signals Each DC output is isolated using open collector output opto-isolators. The output voltage of each line is enabled by putting pull-up resistors on the main board, and by connecting the pull-up resistors to an externally applied DC voltage.

4339B Input Signals The DC isolated input signals are connected to the cathodes of the LEDs in the opto-isolators. The anodes of the LED's are powered by an external voltage source (EXT DCV2). The OFF state voltage (high level) of the DC isolated input signals depends on the pull-up voltage powered by an external; voltage source (EXT DCV2). (The input current is restricted by using a switch on the main board.) The electrical characteristics of the input signals are listed in Table B-2.
