33 Status Reporting
(Standard) Event Status Register (ESR)
The (Standard) Event Status Register (ESR) monitors the following oscilloscope
status events:
• PON - Power On
• URQ - User Request
• CME - Command Error
• EXE - Execution Error
• DDE - Device Dependent Error
• QYE - Query Error
•RQC - Request Control
• OPC - Operation Complete
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.
You can read the contents of the Standard Event Status Register and clear the
register by sending the *ESR? query. The value returned is the total bit weights of
all of the bits that are set at the present time.
Example The following example uses the *ESR query to read the contents of the Standard
Event Status Register.
myScope.WriteString "*ESR?"
varQueryResult = myScope.ReadNumber
MsgBox "Standard Event Status Register: 0x" + Hex(varQueryResult)
If bit 4 (weight = 16) and bit 5 (weight = 32) are set, the program prints the sum of
the two weights.
