Pre pari ng For Use This chap ter g ives you in str uctio ns for p rep arin g th e l ogic analy sis s yste m for u se. Powe r Re qu irem ents The lo gic an alys is system main frame requires a p ower so urce of ei ther 115 Vac or 23 0 Vac, –22 % to +10 %, sing le phase, 48 to 66 Hz, 475 W maximum power.
2 Check the sup plied ac cessori es. Accessori es supplied with the log ic analysis syst em are liste d in "Access orie s" in chapter 1. 3 Inspe ct th e product for physica l damage. Check the lo gic analysis sys tem and t he suppl ied acce ssories for o bvious physi cal o r mechanical defe cts.
To set the line voltage When shipped from HP, the line voltag e selector is set and an appropri ate fuse is installed for operating the instrument in the country of destinat ion. To operat e t he instrument from a power so urce o ther than t he o ne set, perfo rm the fo llo wing steps .
To degauss the display • If the mainfra me has be en subjec te d to strong magn etic field s, the C RT might beco me magn etized an d displa y data might bec ome distorted . To corre ct this cond itio n, deg auss the CRT with a c onven tion al, exter nal -telev ision -typ e deg aussin g co il.
To in stall m odules The following steps give general instruct ions for installing modules into the mainframe or the expansio n frame of the system. CA UT ION El ectrosta tic discharge can damage electroni c components . Use grounded wris tstra ps and mats when perf ormi ng any s ervice to modul es.
To in stall the HP 16500L interface mod ule The HP 16500L interface module is required to connect t he HP 16501A Expansio n Frame to the H P 1650 0B m ainframe. WA RNI NG Haz ardous voltages exi st on the power supply , the CRT, and the C RT driver board of the HP 16500 B mainframe.
5 Slide the inter fa ce mod ule into the main frame thro ug h the slo t i n the rear pan el. 6 Install the scr ews co nnectin g the i n terface mo dule to the mai nframe .
To connect the HP 16501A Expansion Frame The HP 1 6 501A Expansio n Frame includes an interface cabl e and re qui res an H P 16500 L interface module to connect to the H P 16500B mainframe. To install the expans ion frame, you need to install the inte rface module into the mainframe, then connect the cable from the module to the expansio n frame.

Testi ng Perfor mance To ensure the logic analys is sy stem is o perating correctly, you can perform software tests (s elf-tests ) on the sy stem. Dire ction s for pe rformin g th e s oftware te sts are give n i n this chap ter.
To per f or m t he powe r - up tes ts The logic analysis syste m automat ically performs power- up tests when you apply power to the instrument . T he revision number of the boot ROM shows in t he upper-right corner of the screen during thes e power-up tests.
To p erform the self-tests The s elf-tests ver ify th e cor rect oper ation of th e lo gic an alys is sy stem. Sel f-tests can be pe rformed all at once or one at a time. While testin g the p erfor mance of the logi c anal ysis sys tem, ru n the self-tes ts all at once.
5 Install a formatted d i sk that is not write protected i nto the flexib le d isk dr ive. Conn ect an RS- 232C loopb ack conne ctor onto the RS- 232C port. 6 Select All System Tests . You can run all tests at one time b y running All System Tests. To s e e more detail s about each test, yo u can run each test individually.

Bloc k-Le v e l Theory The b lock-le vel th eor y is d ivid ed into two parts : theory for th e l ogic analy s is s yste m and theory for the micr oproces sor bo ard.
System Ov erview Theory HP 165 00B The HP 16500B is the mainframe for the Logi c Analysis Syst em. Micro processor B o ard The micropro cesso r b oard contains all the interface circuit ry for managing data flow betwee n the mainframe components and the opt ional boards .
HP 165 01A The HP 16501A is the e x pansion frame for the Logi c Analysis System. The expansion fram e component s i nclude t he fo llowing: • Expansio n Interface Bo a rd • Interface Cab le • Mother Bo a rd • Power Supply To connect the expansion frame to the mainframe, you must install an HP 1 6 500L inte rface module into the mainframe.
The Microproces sor Board The M i cropr oces so r Board The ory of Op erat io n The Mi crop roce ssor Bo ard 8– 6.
Micro processor B o ard T heo ry The microprocesso r board cont ains the system memo ry, all of the interfaces for the mainframe peri pherals, the int ermodule b us moni tor, and t he o pti on bo ard module i nterface .
HIL Interface The Hewlett -Packard Human Interface Link ( HP-HIL ) is the interface b etwe en t he microproce ssor and t he H P 16500B front panel. In t he write mode , the int erface cont roll er serializ es the 8-bit data and t ransmits the data to t he devices on the link.
The P owe r-Up Routine When powe r is appli ed to the HP 1 6500 B Logic Analy sis Syste m main frame, a se ries of tasks called the power-u p routi ne is per formed to initial ize and to verify operatio n of th e mainfr a me. T he mai nframe mon itor rep orts th e p rogr ess an d status of th e power-up ro utin e.
Power-Up S elf-Tests All of the power-up self tests are performe d to verify the operati on of the H P 16500B mainframe. If any o f the se lf-t ests fail , then t he po wer-up ro uti ne is halted and t he F ATAL ERRORS EN CO UNTERED , BOO T HALTED m essag e appears .
Initi alizi ng and Cali bratin g Mo dules The install ed mo dules are i niti alized and stored cal ibratio n fact ors are uplo aded fro m eithe r the disk drive or module NV-RAM into sys tem RAM. The configurat ion menu of the module using the calibrat ion facto rs will show if the calibrati on factors have bee n successfully l o aded.
The S ystem Configuration M enu When t he po wer-up routi ne is com plet e and t he HP 165 00B is operat ional, t he Sy stem Configurati on menu is displayed. The names of the installe d modules appear in fields on the left si de o f the displ ay. The fiel ds co rrespo nd to t he sl ot int o whi ch the mo dule i s install ed.
Self-Te sts De scri ption The s elf-tests iden tify th e cor rect oper ation of th e major sub-s yste ms in th e HP 16500B Logic An alys is System mainframe.
RAM T est The RAM T est perform s an abbreviat ed read/writ e test at various memory locatio ns. The t est returns a pass o r fail mess age. F or RAM Test failures, first you can suspect a faulty SIMM module, then you can suspect a faulty microproce ssor board.
Correlator T est The correlat or t est verifies that the int ermo dule b us tim e co rrelat or o n t he mi croprocesso r board i s funct ioning pro perly. If t he co rrelat or is funct io ning, then inte rmodul e measurement s can be t i me-correlat ed to withi n 2 ns.
RAM T est This test checks t he mainframe RAM on the microprocessor board. The t est performs a non-dest ructive patt ern wri te/read at eve ry locati on. The ini tial RAM co ntents are res tor ed after the test. For RAM Test failures, first y o u can suspect a faulty SIMM module, then you can suspect a fault y mi cropro cesso r board.
Poss ible pro blems causing a fail ed message in e ithe r the flex ible disk drive or hard disk drive include the fol lowi ng: • A damaged o r dis connect ed di sk drive cab le. • Wrong disk formatt ing or no disk formatt ing. • The disk write- protect tab set to the write -prot ect position.
