Page 67: Error Messages
Troubleshooting Error Messages Error Messages If an error condition occurs in the signal generator, it will always be reported to both the front panel display error queue and the SCPI (remote interface) error queue. These two queues are viewed and managed separately. The Front Panel Error Queue This queue is designed in a circular (rotating) fashion.
Page 68 Troubleshooting Error Messages -350,Queue overflow When the queue overflows, the least recent errors remain in the queue, and the most recent error is discarded. Reading an error from the head of the queue removes that error from the queue, and opens a position in the tail of the queue for a new error, if one is subsequently detected.
Page 69: Querying The Error Queue
Troubleshooting Querying the Error Queue Querying the Error Queue The queue query message is a request for the next entry from the instrument’s error queue. This queue contains an integer that can range from -32768 to 32767. Negative error numbers are reserved by the SCPI standard and are defined in this section.
