Appendix A: SCPI Command Reference Model 3390 Arbitrary Waveform Generator User’s Manual SCPI status model The SCPI status model shows the structure of the various registers used by the Model 3390 (Figure A-1). These registers record conditions of the instrument and allow you to monitor and manipulate events. The core of the model is the Status Byte Register.
Model 3390 Arbitrary Waveform Generator User’s Manual Appendix A: SCPI Command Reference Status register sets Condition register: Contains the current status of the hardware and firmware, is continuously updated, and is not latched or buffered. Condition registers are read-only. Event register: Latches transition events from the condition register. Event registers are cleared by reading, by query command, or with the *CLS command.
Appendix A: SCPI Command Reference Model 3390 Arbitrary Waveform Generator User’s Manual Questionable Data Register The Questionable Data Register reports information regarding possible instrument problems (Table A-4). The Questionable Data Register is enabled by using the STAT:QUES:ENAB command. Refer to Figure A-1 for condition register, event register, and enable register queries. Clear the Questionable Data event register by querying the register, or with a *CLS (clear status) command.

Appendix B: Error Messages Model 3390 Arbitrary Waveform Generator User’s Manual Introduction Error messages are issued when an incorrect command is sent to the Keithley Instruments Model 3390 Arbitrary Waveform Generator. Error messages are stored in an error queue and can be retrieved in the first-in-first-out (FIFO) order. If more than 20 errors exist, the last error stored in the queue (the most recent error) is replaced with -350, Queue Overflow.
Model 3390 Arbitrary Waveform Generator User’s Manual Appendix B: Error Messages Table B-1: Command errors Error code Description -148 Character data not allowed A discrete parameter was received when it was not expected. An invalid character string was received. A character string was received when it was not permitted for this command.
