  • Page 20: 3.6 Common Commands

    The following commands are common to all SCPI instruments and declared mandatory by IEEE 488.2. In the following table, the AFV-P Series will be defined as the “device” on the GPIB bus. These commands are further supported on the RS-232 command interface.

  • Page 21: Section 4 Rs-232 Interface

    SECTION 4 RS-232 INTERFACE This section describes how to connect the AFV-P for remote programming with a controller using the RS232 interface. The RS-232 interface provides a simpler 3-wire serial interface (compared to the GPIB parallel interface), while fully supporting the SCPI commands presented in Section 3.

  • Page 23: Appendix A: Status Register Definitions

    GPIB serial poll. Either operation clears the contents of the Status Byte. The *CLS command clears the Status Byte. The AFV-P Series unit can be configured to request service from the GPIB controller by setting the appropriate bits in the Service Request Enable register. The SRE register has the same bit pattern as the Status Byte.

  • Page 24: Standard Event Status Register

    Status Enable register is set. Use the *ESE to set bits, and the *ESE? to read this register. To configure the AFV-P Series to generate SRQ's based on the ESR, both the Standard Event Status Enable register and the Service Request Enable registers must be programmed.

  • Page 25: Operation Status/ Questionable Status Registers

    AFV-P Series Status Register Definitions Operation Complete Set whenever the last command is completed and the CW is ready to accept another command, or when query results are available. Query Error Set when a query is made for which no response is available.

  • Page 27: Appendix Berror Codes

    The following error codes are defined in the SCPI 1993.0 specification, and are supported by the AFV-P Series. Error codes are in the range of [-32768, 32767]. SCPI reserves the negative error codes and 0, while error codes greater than 0 are device-specific errors.
  • Page 28 Error Codes AFV-P Series -200, Execution error An error/event number in the range [-299, -200] indicates that an error has been detected by the instrument’s execution control block. The occurrence of any error in this class shall cause the execution error bit (bit 4) in the event status register to be set.

  • Page 29: Appendix C: Sample Programs

    The following examples will illustrate how to perform certain functions on the AFV-P using SCPI via the GPIB interface or the RS-232 channel. NOTE: See the AFV-P Series Operation Manual for examples of how to use Slave commands. Source AC from power up...
