Standard Event Status Register
The standard event status register records the following events that might occur on your instrument:
power-on inspection, command syntax error, command execution error, self-test/calibration error, query
error, or operation completed. All these events or any one of the events can be reported to Bit 5 (ESB, Event
Summary Bit) of status byte register via the enable register. To set the enable register mask, you need to
use the
*ESE command to write a decimal value into the register. The definitions for the bits in the standard
event status register and the decimal value that corresponds to the binary-weighted value are shown in
Table 1-2.

Name
Description
0 1 OPC (Operation complete)
The operation has been completed. All pending
operations were completed following the execution
of the *OPC command.
1 Not used Not used This bit is always set to 0.
2
4
QYE (Query error)
A query error has occurred.
3 8 DDE (Device error)
A device error (error caused by self-test or
calibration) has occurred.
4 16 EXE (Execution error)
An execution error (trigger ignored, initialization
ignored, setting conflict, data over-the-
limit, data
length too long, or invalid parameter value) has
occurred.
5 32 CME (Command error)
A command error (command syntax error) has
occurred.
6 Not used Not used This bit is always set to 0.
7 128 PON (Power on)
Power-on test. After the bit has been read from the
last event of the register or has been cleared, turn
off the instrument and then turn it on again.
Status Byte Register
The status byte register reports the status information about other status registers; queries the report of Bit
4 (MAV, Message Available) data to be queried in the output buffer. The summary bit in the status byte
register will not be latched. Clearing the event register will clear the corresponding summary bits of the
status byte register. Read all the information in the output cache (including any pending queries), and will
clear Bit 4 (MAV, Message Available). The definitions for the bits in the status byte register and the decimal
value that corresponds to the binary-weighted value are shown in Table 1-3.
