Introduction This chapter introduces you to the basics of remote programming andis organized in two sections. The first section, "Talking to theInstrument," concentrates on initializing the bus, program syntax andthe elements of a syntax instruction. The second section, "ReceivingInforma...

Talking to the Instrument In general, computers acting as controllers communicate with theinstrument by sending and receiving messages over a remoteinterface, such as GPIB or RS-232-C. Instructions for programmingthe Agilent Technologies 1670G-series logic analyzer will normallyappear as ASCII chara...

Initialization To make sure the bus and all appropriate interfaces are in a known state,begin every program with an initialization statement. BASIC provides aCLEAR command that clears the interface buffer. If you are using GPIB,CLEAR will also reset the parser in the logic analyzer. The parser is th...

Instruction Syntax To program the logic analyzer remotely, you must have an understanding ofthe command format and structure. The IEEE 488.2 standard governs syntaxrules pertaining to how individual elements, such as headers, separators,parameters and terminators, may be grouped together to form com...

Device Address The location where the device address must be specified also depends on thehost language that you are using. In some languages, this could be specifiedoutside the output command. In BASIC, this is always specified after thekeyword OUTPUT. The examples in this manual use a generic addr...

When you look up a query in this programmer’s reference, you’ll find aparagraph labeled "Returned Format" under the one labeled "Query." Thesyntax definition by "Returned format" will always show the instructionheader in square brackets, like [:SYSTem:MENU], which means the t...

Header Types There are three types of headers: Simple Command, Compound Command,and Common Command. Simple Command Header Simple command headers contain a single keyword. START and STOP areexamples of simple command headers typically used in this logic analyzer.The syntax is: <function><ter...

Common Command Header Common command headers control IEEE 488.2 functions within the logicanalyzer, such as, clear status. The syntax is: *<command header><terminator> No white space or separator is allowed between the asterisk and thecommand header. *CLS is an example of a common comman...

Query Usage Logic analyzer instructions that are immediately followed by a question mark(?) are queries. After receiving a query, the logic analyzer parser places theresponse in the output buffer. The output message remains in the bufferuntil it is read or until another logic analyzer instruction is...

Program Header Options Program headers can be sent using any combination of uppercase orlowercase ASCII characters. Logic analyzer responses, however, are alwaysreturned in uppercase. Both program command and query headers may be sent in either long form(complete spelling), short form (abbreviated s...

Parameter Data Types There are three main types of data which are used in parameters. They arenumeric, string, and keyword. A fourth type, block data, is used only for a fewinstructions: the DATA and SETup instructions in the SYSTem subsystem(see chapter 11); the CATalog, UPLoad, and DOWNload instru...

Selecting Multiple Subsystems You can send multiple program commands and program queries for differentsubsystems on the same line by separating each command with a semicolon.The colon following the semicolon enables you to enter a new subsystem. <instruction header><data>;:<instructio...

Receiving Information from the Instrument After receiving a query (logic analyzer instruction followed by a questionmark), the logic analyzer interrogates the requested function and places theanswer in its output queue. The answer remains in the output queue until itis read, or, until another comman...

Response Header Options The format of the returned ASCII string depends on the current settings ofthe SYSTEM HEADER and LONGFORM commands. The general format is <instruction_header><space><data><terminator> The header identifies the data that follows (the parameters) and is c...

Response Data Formats Both numbers and strings are returned as a series of ASCII characters, asdescribed in the following sections. Keywords in the data are returned in thesame format as the header, as specified by the LONGform command. Likethe headers, the keywords will always be in uppercase. Exam...

String Variables Because there are so many ways to code numbers, the AgilentTechnologies 1670G-series logic analyzer handles almost all data as ASCIIstrings. Depending on your host language, you may be able to use othertypes when reading in responses. Sometimes it is helpful to use string variables ...

The output of the logic analyzer may be numeric or character data dependingon what is queried. Refer to the specific commands, in Parts 2 and 3 of thisguide, for the formats and types of data returned from queries. Example The following example shows logic analyzer data being returned to a stringvar...

This time the format of the number (such as, whether or not exponentialnotation is used) is dependent upon your host language. The output willresemble 1.E-5 in BASIC. Definite-Length Block Response Data Definite-length block response data, also referred to as block data, allows anytype of device-dep...

Multiple Queries You can send multiple queries to the logic analyzer within a single programmessage, but you must also read them back within a single program message.This can be accomplished by either reading them back into a string variableor into multiple numeric variables. Example You can read th...

Instrument Status Status registers track the current status of the logic analyzer. By checkingthe instrument status, you can find out whether an operation has beencompleted, whether the instrument is receiving triggers, and more.Chapter 6, "Status Reporting," explains how to check the status...

Interface Capabilities The interface capabilities of the Agilent 1670G-series logic analyzer, asdefined by IEEE 488.1 are SH1, AH1, T5, TE0, L3, LE0, SR1, RL1, PP0, DC1,DT1, C0, and E2. Command and Data Concepts GPIB has two modes of operation: command mode and data mode. The busis in command mode w...

If the controller addresses the instrument to talk, it will remain configured totalk until it receives: • an interface clear message (IFC) • another instrument’s talk address (OTA) • its own listen address (MLA) • a universal untalk (UNT) command If the controller addresses the instrument to listen,...

Bus Commands The following commands are IEEE 488.1 bus commands (ATN true). IEEE488.2 defines many of the actions which are taken when these commands arereceived by the logic analyzer. Device Clear The device clear (DCL) or selected device clear (SDC) commands clear theinput and output buffers, rese...

Interface Operation The Agilent 1670G-series logic analyzer can be programmed with a controllerover RS-232-C using either a minimum three-wire or extended hardwireinterface. The operation and exact connections for these interfaces aredescribed in more detail in the following sections. When you arepr...

Minimum Three-Wire Interface with Software Protocol With a three-wire interface, the software (as compared to interfacehardware) controls the data flow between the logic analyzer and thecontroller. The three-wire interface provides no hardware means to controldata flow between the controller and the...

Truncation Rule The truncation rule for the keywords used in headers and parameters is: If the long form has four or fewer characters, there is no change in the shortform. When the long form has more than four characters the short form isjust the first four characters, unless the fourth character is...

Infinity Representation The representation of infinity is 9.9E+37 for real numbers and 32767 forintegers. This is also the value returned when a measurement cannot bemade. Sequential and Overlapped Commands IEEE 488.2 makes the distinction between sequential and overlappedcommands. Sequential comman...
