The Enable Register acts like a gate for the Interrupt Operation Register . If the
Event Register is not enabled (i.e. gate is close), the interrupt signal will not be
sent to the Status Byte Register . If the Event Register is enabled, the interrupt
signal will be sent to bit 0 of the Status Byte Register . To check whether the
Enable Register is enabled, use the following SCPI command:
STAT:INT:ENAB?
If the return value is “
1
” (in binary is 01), it means that the information at bit 0 of
Event Register in Interrupt Operation Register will be sent to bit 0 of Status Byte
Register . If the return value is “
2
” (in binary is 10), it means that the information at
bit 0 of Event Register in Interrupt Operation Register will be sent to bit 0 of
Status Byte Register . To enable both bit 0 and bit 1 of Enable Register to send the
information in bit 0 and bit 1 of Event Register in Interrupt Operation Register ,
send the following SCPI command:
STAT:INT:ENAB 3
The user may send the SCPI command “
*STB?
” to query the status of the Status
Byte Register and observe bit 0 of the return value to check whether an interrupt
has occured provided that the user has previously select the trigger source and
enable the Enable Register of the Interrupt Operation Register .
The flowchart in Figure 3-6 shows an example of the interrupt function operation.
