Monitoring the Instrument
Standard Event Status register
The Standard Event Status Register monitors the following instrument status events:
• OPC - Operation Complete
• RQC - Request Control
• QYE - Query Error
• DDE - Device Dependent Error
• EXE - Execution Error
• CME - Command Error
• URQ - User Request
• PON - Power On
When one of these events occur, the event sets the corresponding bit in the register.
If the bits are enabled in the Standard Event Status Enable Register, the bits set in
this register generate a summary bit to set bit 5 (ESB) in the Status Byte Register.
