Status and Event
*CLS Clear Status Command
Sets bits of the 'Standard Event Status Register' and of the 'Status Byte Register' to zero.
Sending *CLS as a single command or as the first command of a string also clears the
contents of the Output Queue.
*ESE Standard Event Status Enable Command
*ESE, followed by a decimal value, sets the bits of the 'Standard Event Status Enable
Register.' This enables the assigned bits of the 'Standard Event Status Register,' see
Page 6-15.
*ESE? Standard Event Status Enable Query
This query asks the instrument for the contents of the 'Standard Event Status Enable
Register.' The response is a decimal value.
Example: 255 = all bits are set to 1: all events of the 'Standard Event Status
Register' are enabled.
*ESR? Standard Event Status Register Query
Asks for the contents of the 'Standard Event Status Register.' The response is a decimal
value. This query also clears the register contents.
*SRE Service Request Enable Command
*SRE, followed by a decimal value, sets the bits to 1 of the 'Service Request Enable
Register', except bit 6. For more detail on the assigned bits of the 'Status Byte Register,'
see Page 6-15.
*SRE? Service Request Enable Query
Asks for the contents of the 'Service Request Enable Register.' The response is a decimal
value.
*STB? Read Status Byte Query
Asks for the contents of the 'Status Byte Register.' The response is a decimal value.
Sending this query using IEEE-488 Interface causes the 54200 to set bit 4 (MAV) of the
Status Byte Register. The output is 16 dec if no further bits are set.
