The Standard Event Register

The Standard Event register reports the following types of instrument events: power-on detected, command syntax errors, command execution errors, self- test or calibration errors, query errors, or when an *OPC command is executed. Any or all of these conditions can be reported in the standard event summary bit (ESB, bit 5) of Status Byte register through the enable register. To set the enable register mask, you write a decimal value to the register using the *ESE (Event Status Enable) command.

An error condition (Standard Event register bit 2, 3, 4, or 5) will always record one or more errors in the power supply’s error queue. Read the error queue using the SYST:ERR? command.

Table 4-4. Bit Definitions – Standard Event Register

	Bit		Decimal	Definition
			Value
0		OPC	1	Operation Complete. All commands prior to and
				including an *OPC command have been executed.
1		Not Used	0	Always set to 0.
2		QYE		Query Error. The power supply tried to read the output
			4	buffer but it was empty. Or, new command line was
				received before a previous query had been read. Or, both
				the input and output buffers are full.
3		DDE	8	Device Error. A self-test or calibration error occurred
				(see error numbers 601 through 750 in chapter 5).
4		EXE	16	Execution Error. An execution error occurred (see error
				numbers -211 through -224 in chapter 5).
5		CME	32	Command Error. A command syntax error occurred (see
				error numbers -101 through -178 in chapter 5).
6		Not Used	0	Always set to 0.
7		PON	128	Power On. Power has been turned off and on since the
				last time the event register was read or cleared.
