Part 1 1 Introduction to Programming 2 Module Level Commands General Information

Introduction This chapter introduces you to the basic command structure used toprogram the logic analyzer. Also included is an example program thatsets up the timing analyzer for a basic timing measurement.Additional program examples are in chapter 18. 1–2

Selecting the Module Before you can program the logic analyzer, you must first "select" it. Thisdirects your commands to the logic analyzer. To select the module, use the system command :SELect followed by thenumeric reference for the slot location of the logic analyzer (1 through 10refering...

Mainframe Commands These commands are part of the HP 16500/16501A mainframe system andare mentioned here only for reference. For more information on thesecommands, refer to the HP 16500/16501A Programmer’s Guide . CARDcage? Query The CARDcage query returns a string of integers which identifies themo...

MENU Command/query The MENU command selects a new displayed menu. The first parameter (X)specifies the desired module. The optional, second parameter specifies thedesired menu in the module. The second parameter defaults to 0 if it is notspecified. The query returns the currently selected and displa...

STOP Command The STOP command stops the specified module. If the specified module isconfigured as part of an intermodule run, STOP will stop all associatedmodules. STARt and STOP are overlapped commands. Overlapped commands allowexecution of subsequent commands while the logic analyzer operationsini...

Command Set Organization The command set for the HP 16554A/HP 16555A/HP 16555D is divided intomodule-level commands and subsystem commands. Module-level commandsare listed in Chapter 2, "Module Level Commands" and each of the subsystemcommands are covered in their individual chapters startin...

Introduction The DATA and SETup commands are SYSTem commands that allowyou to send and receive block data between the HP 16554A,HP 16555A, or HP 16555D and a controller. Use the DATA instructionto transfer acquired timing and state data, and the SETup instructionto transfer instrument configuration ...

Data Format To understand the format of the data within the block data, there are fourimportant things to keep in mind. • Data is sent to the controller in binary form. • Each byte, as described in this chapter, contains 8 bits. • The first bit of each byte is the MSB (most significant bit). • Byte ...

<block data> <block length specifier><section>... <block length specifier #8<length> <length> the total length of all sections in byte format (must be represented with 8digits) <section> <section header><section data> <section header> 16 bytes...

Section Header Description Because block data may contain multiple sections, this description numbersbytes beginning at the section header. The initial 10 bytes of the block lengthspecifier and any other sections are not included in the numbering. The section header uses bytes 1 through 16 (this man...

Data Preamble Description The UNPacked block data is organized as 574 bytes of preamble information,followed by a variable number of bytes of data. The preamble givesinformation for each analyzer describing the amount and type of datacaptured, where the trace point occurred in the data, which pods a...

Byte Position 37 4 bytes - List of pods in this analyzer, where a binary 1 indicates that thecorresponding pod is assigned to this analyzer bit 31 bit 30 bit 29 bit 28 bit 27 bit 26 bit 25 bit 24 unused unused unused unused unused unused unused unused bit 23 bit 22 bit 21 bit 20 bit 19 bit 18 bit 17...

Acquisition Data Description The acquisition data section consists of a variable number of bytes dependingon the number of cards in the configuration, the acquisition mode, and thestate tag setting. The data is grouped in rows of bytes with one sample fromeach pod in a single row. The width of the r...

Example A three-card configuration with 516096 valid rows First data byte = byte 591 Last data byte = 14,451,278 [591 + (28 × 516096) - 1] Time Tag Data Description If tags are enabled for one or both analyzers, the tag data follows theacquisition data. The first byte of the tag data is determined a...

The examples are written in HP BASIC6.0. • Making a timing analyzer measurement • Making a state analyzer measurement • Making a state compare analyzer measurement • Transferring logic analyz...

Making a Timing Analyzer Measurement This program sets up the logic analyzer to make a simple timing analyzermeasurement. This example can be used with E2422-60004 Logic AnalyzerTraining board to acquire and display the output of the ripple counter. It canalso be modified to make any timing analyzer...

Making a State Analyzer Measurement This state analyzer program selects the HP 16554A/HP 16555A/HP 16555Dmodule, displays the configuration menu, defines a state machine, displaysthe state trigger menu, sets a state trigger for multilevel triggering. Thisprogram then starts a single acquisition meas...

Making a State Compare Analyzer Measurement This program example acquires a state listing, copies the listing to thecompare listing, acquires another state listing, and compares both listings tofind differences. This program is written so that you can run it with the HP E2433-60004 LogicAnalyzer Tra...

Transferring the Logic Analyzer Configuration This program uses the SYSTem:SETup query to transfer the configuration of the logic analyzer to your controller. This program also uses the SYSTem:SETup command to transfer a logic analyzer configuration from the controller back to the logic analyzer. Th...

Checking for Measurement Completion This program can be appended to or inserted into another program when youneed to know when a measurement is complete. If it is at the end of aprogram it will tell you when measurement is complete. If you insert it into aprogram, it will halt the program until the ...
