Page 3 This guide, combined with the HP 16500/16501A Programmer’s Guide, provides you with the information WLISt Subsystem needed to program the HP 16554A and HP 16555A/D logic analyzer modules. Each module has its own reference to SFORmat Subsystem supplement the mainframe manual since not all mainframes will be configured with the same modules.
Page 4 Part 3, chapter 18, contains program examples of actual tasks that show you how to get started in programming the HP 16554A and HP 16555A/D logic analyzers. These examples are written in HP BASIC 6.2; however, the program concepts can be used in any other popular programming language.

Page 76: Sformat Subsystem Sformat
SFORmat Subsystem SFORmat SFORmat Selector :MACHine{1|2}:SFORmat The SFORmat (State Format) selector is used as a part of a compound header to access the settings in the State Format menu. It always follows the MACHine selector because it selects a branch directly below the MACHine level in the command tree.

Page 79: Master
SFORmat Subsystem MASTer MASTer Command :MACHine{1|2}:SFORmat:MASTer <clock_id>, <clock_spec> The MASTer clock command allows you to specify a master clock for a given machine. The master clock is used in all clocking modes (Master, Slave, and Demultiplexed). Each command deals with only one clock (J,K,L,M); therefore, a complete clock specification requires four commands, one for each clock.
Page 80: Mode
The MODE command places an HP 16555 state analyzer in either 100 MHz (normal) or 110 MHz (fast) mode. The HP 16554A has only one state analysis mode, 70 MHz. In 110-MHz mode, the h and j resource terms are not available.

Page 85: Slave
SFORmat Subsystem SLAVe SLAVe Command :MACHine{1|2}:SFORmat:SLAVe <clock_id>, <clock_spec> The SLAVe clock command allows you to specify a slave clock for a given machine. The slave clock is only used in the Slave and Demultiplexed clocking modes. Each command deals with only one clock (J,K,L,M); therefore, a complete clock specification requires four commands, one for each clock.
Page 86: Sopqual
SFORmat Subsystem SOPQual SOPQual Command :MACHine{1|2}:SFORmat:SOPQual <clock_pair_id>, <qual_operation> The SOPQual (slave operation qualifier) command allows you to specify either the AND or the OR operation between slave clock qualifier pair 1/2, or between slave clock qualifier pair 3/4. For example you can specify a slave clock operation qualifier 1 AND 2.
Page 87: Squal
SFORmat Subsystem SQUal SQUal Command :MACHine{1|2}:SFORmat:SQUal <qual_num>,<clock_id>,<qual_level> The SQUal (slave qualifier) command allows you to specify the level qualifier for the slave clock. <qual_num> {1|2|3|4} <clock_id> {J|K|L|M} <qual_level> {OFF|LOW|HIGH} Example OUTPUT XXX;":MACHINE2:SFORMAT:SQUAL 1,J,LOW" Query :MACHine{1|2}:SFORmat:SQUal?<qual_num> The SQUal query returns the qualifier specified for the slave clock.

Page 90 Introduction The STRigger subsystem contains the commands available for the State Trigger menu in the HP 16554A/HP 16555A/HP 16555D logic analyzer modules. The State Trigger subsystem will also accept the STRace selector as used in previous HP 16500-Series logic analyzer modules to eliminate the need to rewrite programs containing STRace as the selector keyword.

STRigger (STRace) Subsystem STRigger (STRace) STRigger (STRace) Selector :MACHine{1|2}:STRigger The STRigger (STRace) (State Trigger) selector is used as a part of a compound header to access the settings found in the State Trace menu. It always follows the MACHine selector because it selects a branch directly below the MACHine level in the command tree.
Page 97: Branch
STRigger (STRace) Subsystem BRANch BRANch Command :MACHine{1|2}:STRigger:BRANch<N> <branch_qualifier>,<to_level_number> The BRANch command defines the branch qualifier for a given sequence level.

OUTPUT XXX;":MACHINE1:STRIGGER:BRANCH1 ’((A OR B) AND (F OR G))’, 2" Terms A through E, RANGE 1, and TIMER 1 must be grouped together and terms F through J, RANGE 2, and TIMER 2 must be grouped together.
Page 100: Find
STRigger (STRace) Subsystem FIND FIND Command :MACHine{1|2}:STRigger:FIND<N> <proceed_qualifier>,<occurrence> The FIND command defines the proceed qualifier for a given sequence level. The qualifier tells the state analyzer when to proceed to the next sequence level. When this proceed qualifier is matched the specified number of times, the sequencer will proceed to the next sequence level.
Page 101: Mlength
Valid memory depths range from 4096 states (or samples) through the maximum system memory depth minus 8192 states (HP 16554A or HP 16555A) or minus 16384 states (HP 16555D). Memory depth is affected by acquisition mode. If the <memory_length> value sent with the command is not a legal value, the closest legal setting will be used.
Page 102: Range
STRigger (STRace) Subsystem RANGe RANGe Command :MACHine{1|2}:STRigger:RANGe<N> <label_name>, <start_pattern>,<stop_pattern> The RANGe command allows you to specify a range recognizer term for the specified machine. Since a range can only be defined across one label and since a label must contain 32 or fewer bits, the value of the start pattern or stop pattern will be between (2 )−1 and 0.

Page 104: Store
STRigger (STRace) Subsystem STORe STORe Command :MACHine{1|2}:STRigger:STORe<N> <store_qualifier> The STORe command defines the store qualifier for a given sequence level. Any data matching the STORe qualifier will be stored in memory as part of the current trace data. The qualifier may be a single term or a complex expression.
Page 105: Tag
STRigger (STRace) Subsystem Command :MACHine{1|2}:STRigger:TAG {OFF|TIME| state_tag_qualifier < >} The TAG command selects the type of count tagging (state or time) to be performed during data acquisition.

Page 110: Tposition
STRigger (STRace) Subsystem TPOSition TPOSition Command :MACHine{1|2}:STRigger:TPOSition {STARt|CENTer|END| POSTstore,<poststore >} The TPOSition (trigger position) command allows you to set the trigger at the start, center, end or at any position in the trace (poststore). Poststore is defined as 0 to 100 percent with a poststore of 100 percent being the same as start position and a poststore of 0 percent being the same as an end trace.
