    HP 1650B/51B. For example, HP 9000 Series 200/300 BASIC uses the OUTPUT statement for sending commands and queries to the HP 1650B/51B. After a query is sent, the response is usually read in using the ENTER statement. All progr amming examples in this manual are presented in BASIC.

  • Page 19: Device Address

    Output Command The output command is entirely dependant on the language you choose to use. Throughout this manual HP 9000 Series 200/300 BASIC 4.0 is used in the programmin g examples. People using another language will need to CLEAR in order to convert the examples. The instructions for the HP 1650B/51B are always shown between the double-quotes.

    BASIC provides a CLEAR command which clears the interface buffer. If you’re using HP-IB, CLEAR will also reset the HP 1650B/XB’s parser. The parser is the program which reads in the instructions which you send it.

    String Variables Since there are so many ways to code numbers, the HP 1650B/XB handles almost all data as ASCII strings. Depending on your host language, you may be able to use other types when reading in responses. Sometimes it is helpful to use string variables in place of constants to send instructions to the HP 1650B/51B.

    Addressing By using the front-panel I/O and SELECT keys, the HP-IB interface can be placed in either talk only mode (Printer connected to HP-IB) or addressed talk/listen mode (Controller connected to HP-IB) (see “I/O Port Configuration” in chapter 5 of the HPl65OBIHP 1651B Front-Panel Reference manual).

    DEVICE ADDRESS = (Interface Select Code) X 100 + (Instrument Address) For example, if the instrument address for the HP 1650B/51B is 4 and the interface select code is 7, when the program message is passed, the routine performs its function on the instrument at device address 704.

  • Page 56: Subsystems

    Command Set The command set for the HP 1650B/51B logic analyzer is divided into 17 separate groups: common commands, system commands and 15 sets of Organization subsystem commands. Each of the 17 groups of commands is described in the following chapters. Each of the chapters contain a brief description of the subsystem, a set of syntax diagrams for those commands, and finally, the commands for that subsystem in alphabetical order.

    Examples and appendices were written on an HP 9000 Series 200/300 controller using the HP BASIC 4.0 language. The programs always assume a generic address for the HP 1650B/51B of XXX. In the following examples, special attention should be paid to the ways in which the command and/or query can be sent.

  • Page 59: Common Commands

    Common commands can be received and processed by the HP 1650B/51B whether they are sent over the bus by themselves or as part of a multiple-command string. If an instrument subsystem has been selected and a common command is received by the instrument, the instrument will remain in the selected subsystem.
