Part 1 Part 1 consists of chapters 1 through 8 and contains general information about programming basics, HP-IB, RS-232-C, and LAN interface requirements, documentation conventions, status reporting, and error messages. If you are already familiar with IEEE 488.2 programming and HP-IB or RS-232-C, you may want to just scan these chapters. If you are new to programming logic analyzers you should read part 1. Chapter 1 is divided into two sections. The first section, "Talking to the Instrument,

Introduction This chapter introduces you to the basics of remote programming and is organized in two sections. The first section, "Talking to the Logic Analysis System," concentrates on initializing the bus, program syntax and the elements of instruction syntax. The second section, "Receiving Information from the Logic Analysis System," discusses how queries are sent and how to retrieve query results from the system. The programming instructions explained in this book conform to IEEE Std 488.2

Talking to the Logic Analysis System In general, computers acting as controllers communicate with the instrument by sending and receiving messages over a remote interface, such as HP-IB, RS-232-C, or Ethernet LAN. When programming the HP 16500C with the HP 16501A Expansion Frame connected, most of the remote operation of the expansion frame is transparent. The only time a programming command is affected by the presence of the expansion frame is when the number of slots is specified or returned

Introduction to Programming Talking to Individual System Modules Talking to Individual System Modules Talking to individual system modules within the HP 16500C Logic Analysis System is done by preceding the module commands with the SELECT command and the number of the slot in which the desired module is installed. The mainframe is selected in the same way as an installed module by using the SELECT 0 command. Example To select the module in slot 3 use the following: OUTPUT XXX;":SELECT 3" See Als

Introduction to Programming Initialization Example This BASIC statement would load the configuration file "DEFAULT " (if it exists) into the system. OUTPUT XXX;":MMEMORY:LOAD:CONFIG ’DEFAULT ’" Example This program demonstrates a simple HP BASIC command structure used to program the Logic Analysis System. 10 CLEAR XXX !Initialize instrument interface 20 OUTPUT XXX;":SYSTEM:HEADER ON" !Turn headers on 30 OUTPUT XXX;":SYSTEM:LONGFORM ON" !Turn long form on 40 DIM Card

Introduction to Programming Instruction Syntax Instruction Syntax To program the system remotely, you must have an understanding of the command format and structure. The IEEE 488.2 standard governs syntax rules pertaining to how individual elements, such as headers, separators, parameters and terminators, may be grouped together to form complete instructions. Syntax definitions are also given to show how query responses will be formatted. Figure 1-1 shows the three main syntactical parts of a
