3 Features and Functions
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:
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:
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.
