Introd uction This chap ter intro duces you to the basi cs o f remote pr o gramming and is org anized in two secti on s . The firs t section , "Talk ing to th e Ins trument," concen trates on initiali zing the bu s, program syntax an d the eleme nts of a s yntax i nstructi on. The s econ d secti on, "Rece ivin g Informatio n from the[...]

Talki ng to the Instr umen t In g eneral, compu ters actin g as controll ers communicate wi th th e instru ment by sendi ng an d rece iving message s over a remote interface, such as G PIB or R S-232 - C. Instr uctio n s for prog ramming the Agilen t Te chnolog ies 1670G -series logi c anal yzer will n ormall y appear as ASC II character strin gs e[...]

Initialization To make sure the bus and all appropriate i nterfaces are in a k nown state, begin every program wit h an initial izatio n st atement . BASIC provi des a CLEAR com mand t hat clears t he interface buffer. If yo u are using G PIB, CLEAR will also reset the parser in the logic analyz er. The parser is the program res ident in the logi c[...]

Inst ruction Syntax To program the logic analyze r remotely, you must have an understanding of the command format and structure. The IEEE 488.2 standard governs syntax rules pertaining to how individual element s, such as he aders, separators, parameters and terminat ors, may be grouped toge ther to form complet e instructi ons. Syntax definitio ns[...]

Device A ddress The locati on whe re the devi ce address mus t be specifi ed als o depends o n th e host language that you are using. In some languages, this could be specified outside the output comm and. In BASIC, this is always specifie d after the keyword OUTPU T. The examples in t his manual use a generic address of XXX. When writi ng programs[...]

When yo u look up a que ry in this prog rammer’s reference, yo u’ll fi nd a paragraph labe led "Returne d F ormat" unde r the one labele d "Query. " The syntax definition by "Returne d format" will always show the inst ructio n header in square brack ets, like [:SYSTem:MENU ], which means the text betwe en t he bra[...]

Header Types There are three types of headers: Simple Command, Compo und Command, and Commo n Command. Simple Com m and H eade r Simple co mmand he aders contai n a single key word. START and STO P are example s of simple command headers typi cally used i n this logic analyzer. The syntax is : <function><terminator> When parame ters ( i[...]

Com mon C o mmand He ader Common comm and headers cont rol IEEE 488. 2 functio ns within t he logi c analyzer, such as , clear st atus. The syntax is: *<command header><terminator> No whi te space o r se parator is allo wed bet ween the as teri sk and the command header. *CLS is an e x ample of a common command header. Comb ined Com man[...]

Query Usage Logic anal yzer ins truct ions that are immediate ly fo llowed b y a quest ion mark (?) are queries . After receivi ng a query , the lo gic analyzer pars er place s the response in the output buffer. The output mess age remains in the buffer until it is read o r until ano the r logic anal yzer ins truct ion is i ssued. W hen read, the m[...]

Program Header Opt ions Program headers can b e s ent using any comb ination o f uppercas e or lowercase ASCII characters. Lo gic analyz er response s, however, are al ways returned in uppercase. Both pro gram co mmand and q uery headers m ay be sent in ei ther long form (compl ete spelling) , short for m (ab bre viated spelling) , or any combinati[...]

Parameter Data Types There are thre e mai n types o f data which are used in parameters . They are numeric, st ring, and keywo rd. A fourth ty pe, b lock data, is us ed o nly for a fe w instructi ons: the DATA and SE Tup instructio ns in the SYSTem s ubsystem (see chapter 11); the CATalog, UP Load, and DO WNload instruct ions in the MMEMory sub sy [...]

When a syntax definit ion specifies that a number is an integ er, t hat means that the number shoul d be whole. Any fractional part would be ignore d, truncating the numb er. Numeric paramete rs that accept fractio nal values are called real numb ers. All numbers are expect ed to be strings of ASCII characters. Thus, when sending the number 9, you [...]

Select ing Multip le Subsystems You can send multiple program commands and program queries for different subsys tem s on the same line by se parating each co mmand with a sem icol on. The colon foll owing the sem icolon e nabl es you t o enter a new sub system. <instruction header><data>;:<instruction header><data> <termi[...]

Rece i v ing Inform ation from the Instr ume nt After rece iving a query ( logic analyz er instruct ion fol lowe d by a q uestio n mark), the lo gic analyz er interro gate s the req uested functio n and pl aces the answer in it s output queue. The answer rem ains i n the out put que ue unt il it is read, or, until anot her co mmand is issued. When [...]

Response Header Options The format of t he returned ASCII string depends on the current sett ings of the SYSTEM H EADER and LON G F ORM commands. The general fo rmat is <instruction_header><space><data><terminator> The header ident ifie s the dat a that fo llows ( the paramet ers) and is co ntrolle d by is suing a :SYSTEM:HE[...]

Response Data F ormats Both numb ers and strings are returned as a s eries of ASCII charact ers, as describe d in the fo llowing sections . Keywo rds in the data are ret urned i n the same form at as the header, as specifie d by t he LON Gform co mmand. Li ke the headers , the k eywords wil l always be i n uppercase. Example The fo llowing are pos [...]

String Variables Because there are so many ways to code num bers, the Agilent Technologi es 1670G -series log ic analyzer handles almost all data as ASCII strings. Dependi ng o n your hos t language, you may be able to use othe r types whe n reading in re spons es. Someti mes it is he lpful to use string variab les in pl ace o f constant s to s end[...]

The output of the logic analyzer may be numeric or character data depending on what i s querie d. Refer t o the s pecific commands, i n Parts 2 and 3 of this guide, fo r the formats and ty pes of dat a returned fro m querie s. Example The fo llowing e xam ple shows logic analy zer data being re turned to a st ring variable with headers off: 10 O UT[...]

This time the format of the number (such as, whether or not e xpone ntial notati on is used) is dependent upon your host lang uage. The output will resemb le 1.E-5 in BASIC. Defin ite-Length Block Response Data Definit e-l ength b lock res ponse data, also refe rred to as block dat a, allows any type o f device-depende nt dat a to be transm it ted [...]

Multiple Queries You can send multiple queries to the logic analyzer within a single pro gram message, but y ou m ust also read t hem back within a singl e program m essag e. This can b e accomplishe d by either reading them back into a st ring variable or into mul tiple numeric variable s. Example You can read the result of the query :SYSTEM:HE AD[...]
