Standard Event Status Register

Programming the Status Register System

Status Groups

Table 4-4	Standard Event Status Register Bits

Bit	Description

0	Operation Complete. A 1 in this bit position indicates that all pending signal generator operations were completed
	following execution of the *OPC command.

1	Request Control. This bit is always set to 0. (The signal generator does not request control.)

2	Query Error. A 1 in this bit position indicates that a query error has occurred. Query errors have instrument error
	numbers from −499 to −400.

3	Device Dependent Error. A 1 in this bit position indicates that a device dependent error has occurred. Device
	dependent errors have instrument error numbers from −399 to −300 and 1 to 32767.

4	Execution Error. A 1 in this bit position indicates that an execution error has occurred. Execution errors have
	instrument error numbers from −299 to −200.

5	Command Error. A 1 in this bit position indicates that a command error has occurred. Command errors have
	instrument error numbers from −199 to −100.

6	User Request Key (Local). A 1 in this bit position indicates that the Local key has been pressed. This is true even if
	the signal generator is in local lockout mode.

7	Power On. A 1 in this bit position indicates that the signal generator has been turned off and then on.

	Query:	*ESR?
	Response:	The decimal sum of the bits set to 1
	Example:	The decimal value 136 is returned. The decimal sum = 128 (bit 7) + 8 (bit 3).

Standard Event Status Enable Register

The Standard Event Status Enable Register lets you choose which bits in the Standard Event Status Register set the summary bit (bit 5 of the Status Byte Register) to 1.

*ESE <data>	<data> is the sum of the decimal values of the bits you want to enable.
Example:	To enable bit 7 and bit 6 so that whenever either of those bits are set to 1, the Standard Event
	Status summary bit of the Status Byte Register is set to 1. Send the command *ESE 192 (128 +
	64).
Query:	*ESE?
Response:	Decimal value of the sum of the bits previously enabled with the *ESE <data> command.
