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
Value
Definition
0 Operation
Complete
1 All commands before and including *OPC have been executed.
1 not used not used 0 is returned
2 Query Error 4 The instrument tried to read the output buffer but itwas empty, a new command line
was received before a 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 selftest error, 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 not used 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.
Bit Bit Name Decimal

0 not used not used 0 is returned
1 not used not used 0 is returned
2 Error Queue 4 One or more errors in the Error Queue. Use SYSTem:ERRor? to read and delete
errors.
3 Questionable Status
Summary
8 One or more bits are set in the Questionable Data Register. Bits must be enabled, see
STATus:QUEStionable:ENABle.
4 Message
Available
16 Data is available in the instrument's output buffer.
5 Event Status
Summary
32 One or more bits are setin the Standard Event Register. Bits must be enabled, see
*ESE.
