1 Introdu ct ion t o Pro gramming.
Introd uction This chap ter intro duces you to th e b asics o f remote programming and is org anized i n two secti ons. The firs t se ction, "Talk ing to th e Ins trument," con centrates on in itializi ng the bus, pr ogram syn tax and the eleme nts of a s yntax instuctio n.
Talki ng to the Instrume nt In general, comput ers acting as contro llers co mmunicate wi th the i nstrum ent by se nding and receivi ng message s over a re mote i nterface, such as GPIB or RS-232 C.
Initialization To make sure t he bus and all appropriat e interface s are in a k nown state, begin every program with an ini tializ ation st atement . BASIC provi des a CLEAR com mand that clears t he interface b uffer. If yo u are using G PIB, CLEAR will also reset the parser i n the logic anal yzer.
Instruct ion Syntax To program the logic analy zer remote ly, you must have an understanding o f the com mand format and st ructure. The IEE E 4 8 8.2 standard gove rns syntax rules pert aining t o how individual element s, such as he aders, separat ors, parameters and te rminators, may be gro uped toge ther t o form com plete instructi ons.
Device A d dr ess The locati on whe re the devi ce address must be specifi ed also de pends on t he host l anguage that yo u are using. In some language s, this could be speci fied outside the output command. In BASIC, this is always s pecifie d after the keyword OUTPUT.
When yo u look up a que ry in this programmer’ s reference , you’ ll find a paragraph labe led "Returne d Format " unde r the one lab ele d "Query.
Header T ypes There are thre e types of headers: Simple Co mmand, Compo und Command, and Commo n Command. Simple Comm and H eader Simple co mmand headers co ntain a si ngle key word. START and STO P are example s of simple co mmand headers typi cally used i n thi s lo gic analyz er.
Co mmo n Com man d H ead er Common command headers cont rol IEEE 4 88. 2 functio ns within t he logic analyzer, such as , clear st atus. The s yntax i s: *<command header><terminator> No whi te space o r separato r is allowed b etween t he asteri sk and the command heade r.
Query Usage Logic anal yzer ins tructions that are imme diately fo llowed b y a q uestion mark (?) are queries . After receiving a q uery, t he logic analyzer pars er places t he response in t he output b uffer. The out put message re mains in t he buffer until it is read or unt il anothe r logic anal yzer ins truct ion is i ssued.
Program Header Options Program headers can b e sent using any co mbinati on of uppercas e or lowercase ASCII characters. Logic anal yzer res ponses, ho wever, are al ways returned in uppercase.
Parameter Data Types There are thre e main ty pes o f data which are used in parame ters. They are numeric, st ring, and keywo rd. A fourt h type, b lock data, is us ed only fo r a fe w instructi ons:.
When a s yntax de finition specifi es that a number i s an integ er, that means that t he number should b e who le. Any fractional part would b e ignore d, truncating the numb er. Numeric param eters t hat accept fract ional value s are called real numb ers.
Select ing M ultip le Su bsystems You can send multiple program com mands and program queries for different subsys tem s o n the same line by se parating each command with a sem icolon. The colon foll owing the semicol on e nables y ou to enter a new subsyst em.
Rece i vi ng Inform ation fr om the Instrume nt After rece iving a query ( logic analyzer i nstructio n followe d by a q ues tion mark), the logic anal yzer int errogate s the req uested function and pl aces the answer in it s output queue. The ans wer remains i n the output queue unt il it is read, o r, unt il anot her command i s issued.
Response Header Options The format of the re turned ASCII string depends on t he current s ettings of the SYSTEM H EADER and LONGFO RM commands. The general fo rmat is <instruction_header><sp.
Response Data Formats Both numb ers and strings are returned as a series 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 LONGfo rm co mmand.
String Variables Because the re are so many ways to co de numbe rs, the 1 660-serie s lo gic analyzers handle almost all data as ASCII string s. Depending on y our host language, y ou m ay be ab le to use other t ypes when re ading in respo nses.
Example The fo llowing e xample s hows log ic analyzer data being re turned to a st ring variable with headers off: 10 OUT PU T XX X; ": SYST EM :H EA DE R OFF" 2 0 DI M Ra ng $[ 30 ] 30 O U.
This time the format o f the numb er (s uch as, whethe r or not exponential notati on i s used) is dependant upon your ho st languag e. In Basic, the output will look like: 1.
Multiple Queries You can send mult iple que ries to the logic anal yzer within a singl e program message, but y ou must also read t hem back wit hin a singl e program m essag e. This can be accomplishe d by ei ther reading them b ack into a string variable or into mul tiple nume ric variable s.
Instrument Stat us Status re gist ers track the current status of the l ogic analyz er. By checki ng the inst rument s tatus , yo u can find out whether an operatio n has bee n complet ed, whe ther the instrument is receivi ng trigge rs, and more . Chapter 6, "St atus Report ing," ex plains ho w to check the st atus of the instrument .
2 Programming Over GPIB.
Introd uction This secti on describ es the interface fu nctions and some gener al con cepts of th e GPIB. In gene ral, these fu nctio n s are defin ed by IEEE 488 .1 (GPIB bus s tandard). The y deal wi th gene ral b u s management issu es, as well as messag es which can be sent o ver th e bus as bu s commands.
Interface Capabilities The interface capabi lities of the 1 660- series lo gic analyzers, as defined b y IEEE 48 8.1 are SH1, AH1, T5 , TE0, L 3, LE0 , SR1, RL1 , PP 0, DC1, DT1 , C0, and E2. Com mand and Data Concept s The GPIB has two m odes of operat ion: command m ode and data mode .
If the co ntro ller addresse s the instrume nt t o talk, i t will re main configure d to talk unt il it receives: • an interface clear m essage (IF C) • another i nstrum ent’s talk addres s (O TA) • its own lis ten address (ML A) • a universal unt alk (UNT) command.
Example F or exam ple, if the ins trument addre ss is 4 and the int erface sele ct code i s 7, the inst ructi on will caus e an actio n in the i nstrument at device addre ss 704 .
Bus Commands The follo wing commands are IEEE 488.1 bus co mmands (A T N t rue). IEEE 488.2 de fines many of t he actions which are tak en when the se commands are received b y the l ogic analyz er.
3 Pro gramm ing Over R S-232C.
Introd uction This chap ter des cribes the interface fun ction s and some general con cepts of the RS-23 2C. The RS-23 2C inte rface on this ins trume nt i s Agilen t Te chnolog ies’ impleme ntation.
Interface Operation The 166 0-series lo gic analyzers can be prog rammed with a control ler over RS-232 C using either a minimum t hree-wire o r exte nded hardwire int erface. The operati on and e x act connect ions for these int erfaces are de scribed i n more det ail in the fo llowing secti ons.
Minimu m Three-Wire Interface with Software Protocol With a three-wire interface, the soft ware ( as compare d to int erface hardware) co ntro ls the dat a flow b etween t he logi c analyzer and the control ler. The t hree-wi re interface provides no hardware means t o cont rol data flow betwee n the cont roller and the log ic analyze r.
• Pin 7 SGND ( Signal G round) • Pin 2 TD (Transmi t Dat a from logic anal yzer) • Pin 3 RD (Re ceive Dat a int o log ic analyze r) The additio nal lines y ou use depe nds on yo ur cont roller’ s implementat ion of the exte nded hardwire int erface.
Cable Examples HP 900 0 Series 300 Figure 3-1 is an exampl e of how to conne ct t he 1660- series lo gic analyzer t o the H P 9862 8A Interface card of an H P 90 00 series 300 co ntro ller. F or mo re informati on o n cabling , refer to the reference m anual fo r your speci fic control ler.

Interface Capabilities The baud rat e, stopbi ts, parity, pro tocol , and databits must be co nfigured exactl y the sam e for b oth the control ler and the log ic analyze r to pro perly communicat e o ver the RS-2 32C bus.
The contro ller and the 1660 -series logic analyze r must b e in the same bit mode t o pro perly com municate over t he RS-2 3 2 C. This me ans that t he control ler m ust have t he capability to send and recei ve 8 bit data.
Lo ckout Com mand To lock out the front -panel cont rols, us e the SYSTem command LO CKout. When t his functio n is on, all contro ls (e xcept t he power s witch) are ent irely locked out. L ocal control can only be re stored b y sending the :LO CKout O FF command.

4 Pro gramm ing an d Docu mentation Co nven tions.
Introd uction This chap ter covers the programmin g conven tion s u sed i n programmin g th e instr ument, as well as the docu mentation con ventions used in th is man ual. Th is chap ter also con tains a d etailed descri ptio n of the comm and tree and command tree traver sal.
Truncation Rule The truncatio n rule for the key words used i n headers and parame ters is: • If the lo ngfo rm has four o r fewer characte rs, there is no change in th e shortfo rm. Whe n the l ongform has m ore than fo ur characters t he shortfo rm is jus t the fi rst four charact ers, unles s the fo urth character i s a vowel.
Infinity Representation The represent atio n of infini ty is 9.9 E+37 fo r real numb ers and 32767 for integers . This is also the value returned when a measurement cannot b e made. Sequ ential and Over lapp ed Comman ds IEEE 48 8.2 m akes the distinct ion be tween seq uential and overlapped commands.
Not ation Conventions an d Definition s The follo wing convent ions are us ed in this manual when des cribing programming rules and ex ample. < > Angular b racket s enclos e words o r characters t hat are used to sym bolize a program co de parameter or a bus command ::= "is define d as.
Comm and Types As shown in chapt er 1, "H eader Types, " there are three t ypes of headers. Each header has a correspondi ng co mmand type. This secti on shows how they rel ate to the com mand t ree. System Com man ds The syst em commands reside at the to p level o f the com mand t ree.
The follo wing exam ples are writ ten using HP BASIC 6 .2 on a HP 900 0 Series 200/30 0 Cont roller. The quote d string i s place d on the bus, fo llowed b y a carriage ret urn and li nefeed (CRL F ). The three X s (XXX) shown in t his manual after an ENTER or O UTPUT st atement represents the device address required by your cont rol ler.

Section Header Descr iption The sectio n header uses b ytes 1 thro ugh 16 (this manual begins co unting at 1; the re is no b yte 0 ). T he 16 byt es of t he secti on header are as follows: Byte Position 1 10 byt es - Sect ion name ("DATA space space s pace space space space" in ASCII for t he DATA instruct i on).
The next 40 byt es are for Analyzer 1 D ata Inform ation. Byte Position 21 1 byte - Machine data mode, o ne of the followi ng decimal val ues: − 1 = off 0 = st ate data wi thout t ags 1 = st ate dat.
Byte Position 26 1 byte - Master chi p for this analyzer. This decimal value returns which chip’s t ime tag data is val id in a non- transitional m ode; for example, s t ate with ti me tags.
