  • Page 21: Common Commands

    The following commands are common to all SCPI instruments and declared mandatory by IEEE 488.2. In the table below, the TW Series will be defined as the “device” on the GPIB bus. These commands are further supported on the RS-232 command interface.
  • Page 22 *IDN? Identification Query. Returns the device identity as an ASCII string: <manufacturer>, <model>, <serial number>, <firmware level>. Example: Elgar, TW Series 5256, 1234, 1.0. *OPC Operation Complete Command. Causes the Operation Complete bit to be set in the Standard Events Status Register when all pending operations are complete.

  • Page 23: Appendix A Status Register Definitions

    *SRE command, and can be read with the *SRE? command. For example, if the SRE register is set to 0x10 (MAV), when the TW Series unit has a message available, the Status Byte register will contain 0x50 (RQS and MAV) and the SRQ line of the GPIB bus will be pulled low indicating a request for service.

  • 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 TW 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

    Operation Status and Questionable Status registers. A.4 ERROR / EVENT QUEUE The TW Series maintains an Error/Event Queue as defined by SCPI. The queue holds up to 10 errors and events. It is queried using the SYSTem:ERRor? command, which reads in a first in, first out manner. The read operation removes the entry from the queue.

  • Page 27: Appendix B Error Codes

    The following error codes are defined in the SCPI 1993.0 specification, and are supported by the TW 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: Device-Specific Error Codes

    SCPI Programming B.3 DEVICE–SPECIFIC ERROR CODES The TW power supply may experience various fault states during operation. The possible fault states can be generated by accidental overloading of the TW supply, or system failures within the TW. DSP Fault 0 DSP Initialization Error This error is reported when the DSP sub-processing system does not boot up.
  • Page 29 SCPI Programming PS A Fault 3 Phase 350 V DC Bus Overvolt Error This error is reported when a given Phase DC internal bus experiences a 350V threshold voltage condition. This error is a run-time recoverable error. From the front panel, press the ENTER key. Through SCPI, send the *RST command.
