This guide, combined with the
HP 16500/16501A Programmer’s
Guide, provides you with the information
needed to program the HP 16554A and
HP 16555A/D logic analyzer modules.
Each module has its own reference to
supplement the mainframe manual since
not all mainframes will be configured with
the same modules.
This manual is organized in three parts.
Part 1 consists of chapters 1 and 2 which
contain general information and
instructions to help you get started.
Chapter 1 also contains:
Mainframe system commands that are
•
frequently used with the logic analyzer
module
HP 16554A/HP 16555A/HP 16555D
•
logic analyzer command tree
Alphabetic command-to-subsystem
•
directory
Chapter 2 contains module-level
commands.
Part 2 consists of chapters 3 through 16
which contain the subsystem commands
for the logic analyzer and chapter 17
which contains information on the
SYSTem:DATA and SYSTem:SETup
commands for this module.

Selecting the Module
Selecting the Module
Before you can program the logic analyzer, you must first "select" it. This
directs your commands to the logic analyzer.
To select the module, use the system command :SELect followed by the
numeric reference for the slot location of the logic analyzer (1 through 10
refering to slots A through J respectively). For example, if the logic analyzer
is in slot E, then the command:
:SELect 5
would select this module. For more information on the select command,
refer to the HP 16500/16501A Programmer’s Guide. It is available through
your HP Sales Office.
Programming the Logic Analyzer
A typical logic analyzer program will do the following:
select the appropriate module
•
name a specified analyzer
•
specify the analyzer type
•
assign pods
•
assign labels
•
sets pod thresholds
•
specify a trigger condition
•
set up the display
•
specify acquisition type
•
start acquiring data
•

Programming the Logic Analyzer
The following example program sets up the logic analyzer to make a simple
timing analyzer measurement.
The three Xs (XXX) after the "OUTPUT" statements in the previous example
refer to the device address required for programming over either HP-IB or
RS-232-C. Refer to your controller manual and programming language
reference manual for information on initializing the interface.
Program Comments
Line 10 selects the logic analyzer in slot C.
Line 20 names machine (analyzer) 1 "TIMING".
Line 30 specifies machine 1 is a timing analyzer.
Line 40 assigns pods 1 and 2 to machine 1.
Line 50 sets up the Timing Format menu by assigning the label COUNT, and
assigning a polarity and channels to the label.
Line 60 selects the trigger pattern for the timing analyzer.
Line 70 sets the range to 100 ns (10 times s/div).
Line 80 changes the onscreen display to the Timing Waveforms menu.
Line 90 inserts the label "COUNT" in the Timing Waveform menu.
Line 100 specifies the Single run mode.
Line 110 starts data acquisition.
For more information on the specific logic analyzer commands, refer to
chapters 2 through 17.

Mainframe Commands
Mainframe Commands
These commands are part of the HP 16500/16501A mainframe system and
are mentioned here only for reference. For more information on these
commands, refer to the HP 16500/16501A Programmer’s Guide.
CARDcage? Query
The CARDcage query returns a string of integers which identifies the
modules that are installed in the mainframe. The returned string is in two
parts. The first five two-digit numbers identify the card type. The
identification number for the HP 16554A and HP 16555A/D logic analyzers is
34. A "−1" in the first part of the string indicates no card is installed in the
slot.
The five single-digit numbers in the second part of the string indicate which
card has the controlling software for the module; that is, where the master
card is located.
Example
12,11,−1,−1,34,2,2,0,0,5
A returned string of 12,11,-1,-1,34,2,2,0,0,5 means that an
oscilloscope time base card (ID number 11) is loaded in slot B and the
oscilloscope acquisition card (ID number 12) is loaded in slot A. The next
two slots (C and D) are empty (−1). Slot E contains a logic analyzer module
(ID number 34).
The next group of numbers (2,2,0,0,5) indicate that a two-card module is
installed in slots A and B with the master card in slot B. The "0" indicates an
empty slot, or the module software is not recognized or is not loaded. The
last digit (5) in this group indicates a one-card module is loaded in slot E.
Complete information for the CARDcage query is in the HP 16500/16501AProgrammer’s Guide.

Mainframe Commands
MENU Command/query
The MENU command selects a new displayed menu. The first parameter (X)
specifies the desired module. The optional, second parameter specifies the
desired menu in the module. The second parameter defaults to 0 if it is not
specified. The query returns the currently selected and displayed menu.
For the HP 16554A/HP 16555A/HP 16555D Logic Analyzers:
X,0 — State/Timing
•
Configuration
X,1 — Format 1
•
X,2 — Format 2
•
X,3 — Trigger 1
•
X,4 — Trigger 2
•
X,5 — Waveform 1
•
X,6 — Waveform 2
•
X,7 — Listing 1
•
If a machine is turned off, its menus are not available. The Mixed Display is
available only when one or both analyzers are state analyzers.
SELect Command/query
The SELect command selects which module or intermodule will have parser
control. SELect 0 selects the intermodule, SELect 1 through 5 selects
modules A through E respectively. Values −1 and −2 select software options
1 and 2. The SELect query returns the currently selected module.
STARt Command
The STARt command starts the specified module. If the specified module is
configured for intermodule (group run), STARt will start all modules
configured as part of the intermodule run.

Mainframe Commands
STOP Command
The STOP command stops the specified module. If the specified module is
configured as part of an intermodule run, STOP will stop all associated
modules.
STARt and STOP are overlapped commands. Overlapped commands allow
execution of subsequent commands while the logic analyzer operations
initiated by the overlapped command are still in progress. For more
information, see *OPC and *WAI commands in Chapter 5 of the
HP 16500/16501AProgrammer’s Guide.
RMODe Command/query
The RMODe command specifies the run mode (single or repetitive) for a
module. If the selected module is configured for intermodule, the
intermodule run mode will be set by this command. The RMODe query
returns the current setting.
SYSTem:ERRor? Query
The SYSTem:ERRor query returns the oldest error in the error queue. In
order to return all the errors in the error queue, a simple FOR/NEXT loop can
be written to query the queue until all errors are returned. Once all errors
are returned, the query will return zeros.
SYSTem:PRINt Command/query
The SYSTem:PRINt command initiates a print of the screen or listing buffer
over the current printer communication interface. The SYSTem:PRINt query
sends the screen or listing buffer data over the current controller
communication interface.
MMEMory Subsystem
The MMEMory Subsystem provides access to both internal disc drives for
loading and storing configurations.
INTermodule Subsystem
The INTermodule Subsystem commands are used to specify intermodule
arming between multiple modules.

Command Set Organization
Command Set Organization
The command set for the HP 16554A/HP 16555A/HP 16555D is divided into
module-level commands and subsystem commands. Module-level commands
are listed in Chapter 2, "Module Level Commands" and each of the subsystem
commands are covered in their individual chapters starting with Chapter 3,
"MACHine Subsystem."
Each of these chapters contains a description of the subsystem, syntax
diagrams, and the commands in alphabetical order. The commands are
shown in long form and short form using upper and lowercase letters. For
example, LABel indicates that the long form of the command is LABEL and
the short form is LAB. Each of the commands contain a description of the
command and its arguments, the command syntax, and a programming
example.
Figure 1-1 on the following page shows the command tree for the
HP 16554A/HP 16555A/HP 16555D logic analyzer module. The (x) following
the SELect command at the top of the tree represents the slot number where
the logic analyzer module is installed. The number may range from 1 through
10, representing slots A through J, respectively.
Each module reports its status to the Module Event Status Register
(MESR<N>), which in turn reports to the Combined Event Status Register
(CESR) in the HP 16500/16501A mainframe (see HP 16500/16501AProgrammer’s Guide chapter 6). The Module Event Status Register is
enabled by the Module Event Status Enable Register (MESE<N>).
The MESE<N> and MESR<N> instructions are not used in conjunction with
the SELect command, so they are not listed in the HP 16554A/HP 16555A/
HP 16555D’s command tree.
The following descriptions of the MESE<N> and MESR<N> instructions
provide the module specific information needed to enable and interpret the
contents of the registers.
