Status Reporting System
Operating Manual 1145.1084.12 – 30 606
detailed plain text error messages that can be looked up in the Error Log or queried via remote control
using SYSTem:ERRor[:NEXT]? or SYSTem:ERRor:ALL?. Each call of SYSTem:ERRor[:NEXT]?
provides one entry from the error queue. If no error messages are stored there any more, the instrument
responds with 0, "No error".
The error queue should be queried after every SRQ in the controller program as the entries describe the
cause of an error more precisely than the status registers. Especially in the test phase of a controller
program the error queue should be queried regularly since faulty commands from the controller to the
instrument are recorded there as well.
