ESG Family Signal Generators
Introduction
If an error condition occurs in the signal generator, it is reported to both the front panel
display error queue and the SCPI (remote interface) error queue. These two queues are
viewed and managed separately.
NOTE When there is an unviewed message in the front panel error queue, the ERR
annunciator appears on the signal generator’s display.
