Programming the Status Register System
The Standard Event Status Group is used to determine the specific event that set bit 5 in
the Status Byte Register. The Standard Event Status Group consists of the Standard
Event Status Register (an event register) and the Standard Event Status Enable Register.
The Standard Event Status Register contains the following bits:
Figure 1-21.
Bit Description
0 A 1 in this bit position indicates that all pending signal generator operations were
completed following execution of the *OPC command.
1 This bit is always set to 0. (The signal generator does not request control.)
2 A 1 in this bit position indicates that a query error has occurred. Query errors have SCPI
error numbers from
−499 to −400.
3 A 1 in this bit position indicates that a device dependent error has occurred. Device
dependent errors have SCPI error numbers from
−399 to −300 and 1 to 32767.
4 A 1 in this bit position indicates that an execution error has occurred. Execution errors
have SCPI error numbers from
−299 to −200.
5 A 1 in this bit position indicates that a command error has occurred. Command errors
have SCPI error numbers from
−199 to −100.
6 A 1 in this bit position indicates that the
Local key has been pressed. This is true even if
the signal generator is in local lockout mode.
7 A 1 in this bit position indicates that the signal generator has been turned off and then
on.
