1 Introdu ct ion to Pro gramming the A gilent Tech nologies 1670G-S eries Logic A nalyzer.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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:.
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.
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.
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.
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><s.
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.
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.
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.
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.
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.
Instrument Stat us Status re gist ers track the current st atus of t he l ogic analyz er. By checki ng the inst rument status , y ou can fi nd out whether an operat ion has b een complet ed, whether the inst rument is receiving t riggers, and more. Chapter 6, "St atus Report ing, " explains ho w to check t he status of the instrument .
2 Programming Over GPIB.
Introd uction This secti on d escrib es the GP I B interface functi ons and some gene ral con cepts of G PIB. In gene ral, thes e functio ns are defin ed by IEE E 488 .1 (GPI B bus s tand ard). The y d eal wi th gene ral b us manag ement issu es, as well as mes sages which can be sent over the bus as bus commands.
Interface Capabilit ies The interface capabi lities of the Agilent 167 0G-se ries logic analyze r, as defined by IEEE 488 .1 are SH1, AH1, T5, TE0, L3, LE0, SR1, RL1, PP0 , DC1, DT1, C0 , and E2. Com mand and Data Concepts GPIB has two mo des of o perat ion: com mand mod e and data m ode.
If the co ntro ller addresse s the ins trume nt to talk, i t wi ll remain co nfigured to talk until it receives: • an interface clear m essage (IF C) • another i nstrum ent’s talk addres s (OTA).
Example F or e xample, if the ins trume nt address i s 4 and t he interface sele ct code i s 7, the inst ructi on will caus e an actio n in the i nstrum ent at de vice addre ss 704.
Bus Commands The follo wing commands are IEEE 4 88.1 bus co mmands (A TN true). IEEE 488.2 de fines many of t he actions which are taken when the se co mmands are received b y t he logi c analyz er.
3 Pro gramm ing Over R S- 232-C.
Introd uction This chap ter des cribes the inte rface function s and some general con cepts of R S-232-C. The RS-232 -C interface on this instr umen t is Agilen t’s i mplemen tation of E IA R ecomme.
Interface Operation The Agilent 1 670G-seri es logi c analyzer can b e programme d wit h a contro ller over RS-2 32-C usi ng either a mini mum three- wire or ex tended hardwi re interface. The operatio n and exact connecti ons for these interfaces are describe d in more detai l in the foll owing sections.
Minimu m Three-Wire Interface with Software Protocol With a three-wire int erface, the software (as compare d to interface hardware) co ntro ls t he data flo w bet ween the l ogic analyz er and the control ler. The three-wi re interface provides no hardware means to control data flow betwee n the control ler and the lo gic analyze r.
• Pin 7 SG ND (Si gnal Ground) • Pin 2 TD ( Transmi t Dat a from logic anal yzer) • Pin 3 RD (Re ceive Data int o log ic analyze r) The additio nal lines y ou us e depends o n your cont rol ler’s i mplementat ion of the ex tended hardwire int erface.
Cable Examples HP 900 0 Series 300 Figure 3-1 is an exampl e of how to connect t he Agile nt 1 670G-se ries to the HP 98628A inte rface card of an HP 9000 series 300 controll er. F or more informati on o n cabling , refer to the refe rence m anual for yo ur specific control ler.

Figure 3-4 shows the schemat ic of a 9-pin female to 25-pin male cabl e. The followi ng cab les suppo rt t his config uratio n: • 2454 2G, DB-9( F) to DB-25 (M), 3 meter • 24542H , DB-9( F) to D B-2 5 ( M), 3 meter, shie lded • 4591 1- 6000 9, D B-9(F ) to D B-2 5(M) , 1 .
Interface Capabilit ies The baud rat e, stopbi ts, parity, pro tocol , and dat abits must be co nfigured exactl y the sam e for b oth the cont roller and the log ic analyze r to properly communicat e over t he RS-2 32-C bus.
The contro ller and the Agilent 1 670 G-serie s logic analyz er must be in th e same bit mode to properly communicate over the RS-232-C. This means that the control ler must have the capability to send and recei ve 8-b it data.
Lo ckout Com mand To lock out the front -panel cont rol s, use t he instrume nt co mmand LO CKout. When this functio n is on, all co ntrols (e xcept the power switch) are entirely locked out . Local cont rol can only be restored by sending the :LOCKout OFF command.

4 Pro gramm ing an d Docu mentation Co nven tion s.
Introd uction This chap ter covers the programmin g conven tions used in programmin g the in strumen t, as well as the documentati on con ventions used in th is manual . Th is chap ter also contains a d etail ed descri ptio n of the comm and tree and command tree traversal.
Truncation Rule The truncation rule for the keywords used in headers and parameters is: If the lo ng form has four or fewer characters, there is no change in the short form. When the long form has more than four characters the short form is just t he first fo ur charact ers, unless the fourt h charact er is a vo wel.
Infinity Representation The represent atio n of infini ty is 9 .9E+37 fo r real numb ers and 32 767 fo r integers . This is also the value returned when a measurement cannot be made. Sequ ential and Over lapp ed Comman ds IEEE 48 8.2 m akes the dist inction betwee n seq uential and ove rlapped commands.
Not ation Convent ions an d Def inition s The follo wing convent ions are us ed in this manual when des cribing programming rules and exampl e. < > Angular b racket s enclos e words o r characte rs that are used to symbo li ze a program code parameter or a bus command ::= "is define d as.
Comm and Types As shown in chapter 1, in the topic, "Header Types," there are three types of headers. Each header has a corresponding command type . This section shows ho w the y relate to the com mand tree. System Com m ands The s ystem commands resi de at the top le vel of the com mand t ree.
The follo wing exam ples are writ te n using HP BASIC 6.2. The q uot ed string is placed on t he b us, fol lowe d by a carri age re turn and linefe ed ( CRLF) . The three Xs (XXX) s hown in thi s manual after an EN TER or O UTP UT stat ement represents the device address required by yo ur control ler.

27 DATA and SETup Com mands.
Introduction The DATA and SETup commands are S Y STem comm ands that send and re ceive block d ata between the Ag ilent 1670G-s eries l ogic anal yzer and a controll er. Use the DATA instr uctio n to transfer acqu ired ti m ing a nd state data, and the S ETup instru ction to tr a nsfe r instru ment configurati on data.
Data Fo rmat To understand the format of the data within the block data, keep these important things in mind. • Data is sent to the controll er in b inary form. • Each byt e, as describ ed in this chapter, co ntains 8 b i ts. • The first bit of each b yte is t he MSB (mo st sig nificant bit).
SYSTem:DA TA Command :S YS Te m:DA TA <bl oc k data > The SYSTem:DA TA command t ransmits the acq uisition m emory dat a from the control ler to the Agil ent 1670G-s eries lo gic analyz er. The blo ck data co nsists of a vari abl e number of byt es containing information captured b y the acq uisition chips .
<block data> <block length specifier><section>... <block length specifier #8<length> <length> the to tal length o f all sect i ons in b yte format (must be re presente.
Section Header Descr iption The sectio n header uses byte s 1 through 16 (this manual beg ins counting at 1; there is no byte 0). The 16 byt es of t he secti on header are as fo llows: Byte Position 1 10 b ytes - Section name ( " DAT A sp ac e sp ac e sp ac e sp ac e sp ac e sp ac e " in A SCII for the DA TA inst ruction) .
The values store d in the preamb le re present the capt ured data currently stored in this struct ure and not the current analyzer configurat ion. For example , the mo de of t he data ( bytes 33 and 1 0 3) may be STATE with tagging, while the current s etup o f the analyzer is TIMING.
Byte Position 41 4 bytes - Master chip for this analy z er 45 4 bytes - Maxim um hardware memo ry de pth available fo r this anal y zer 49 4 bytes - Unused 53 8 by tes - Sam ple period in picoseco nds.
Byte Position 173 88 b ytes - Numb er of valid rows of data (starting at b y te 5 91) for each pod. Bytes 1 73 through 2 28 are unused. Byte Position Bytes 229 through 23 2 - contain the number of valid rows o f data for pod 8. Bytes 233 through 236 - contain the number of valid ro ws of data for pod 7.
Acquisition Data Descrip t ion The acquisi t ion dat a sectio n consist s of a variable numb er of b ytes de pending on the acquisit ion mode and the tag se tting.
The clock pods contain data mapped according to the clock desig nator and the board (se e below) . U nused clock lines should be ignored. po d8 -- 5 po d4 -- 1 Cl oc k Pod 1 < XXXX MLKJ > Where x = not used. Byte Position 591 1 byte - Not use d (MSB of clock pod 2).
