Standard Event Status Group
These registers are programmed by Common commands. The group consists of an Event and Enable
register.The Standard Event event register latches events relating to communication status. It is a
read-only register that is cleared when read. The Standard Event enable register functions similarly
to the enable registers of the Operation and Questionable status groups. Refer to Status Registers for
a description of each register. The following table describes the bit assignments.
Bit Bit Name Decimal

0 Operation

1 All commands before and including *OPC have been executed.
1 notused not used 0 is returned
2 Query Error 4 The instrument tried to read the outputbuffer but itwas empty, a new command line
was received beforea previous query has been read, or both input and output buf-
fers are full.
3 Device-Specific
Error
8 A device-specific error, including a selftesterror, calibration error or other device-
specific error occurred. Error Messages
4 Execution Error 16 An execution error occurred. Error Messages
5 Command 32 A command syntax error occurred. Error Messages
6 notused not used 0 is returned
7 Power On 128 Power has been cycled since the last time the event register was read or cleared.
Status Byte Register
This register summarizes the information from all other status groups as defined in the IEEE 488.2
Standard Digital Interface for Programmable Instrumentation. The following table describes the bit
assignments.

2 Error Queue 4 Oneor more errors in the Error Queue. UseSYSTem:ERRor? to read and delete
errors.
3 Questionable Status
Summary
8 One or more bits are set in the Questionable Data Register. Bits must beenabled, see
STATus:QUEStionable:ENABle.
4 Message
Available
16 Data is available in the instrument's outputbuffer.
5 Event Status
Summary
32 One or more bits are set in theStandard Event Register. Bits must be enabled, see
*ESE.
