Standard Event Register
The standard event register reports the following instrument events: power-on detection command syntax
error, command execution error, self-test or calibration error, query error or operation complete. All these
events or anyone of these events can be reported by the enable register to the bit5 (ESB, Event Summary
Bit) of the status byte register. To set the enable register mask, you need to use the *ESE command to write
a decimal value into the register. The definitions of the bits in the standard event register and the
corresponding decimal values of their binary weights are as shown in Table 1-5.
Note: An error status (bit2, 3, 4 or 5 in the standard event register) records one or more errors in the
power supply error queue and you can send the :SYSTem:ERRor? command to read the error queue.
Table 1-5 Definitions of the bits in the standard event register and the corresponding decimal values of their
binary weights
Bit Decimal Value Definition
0 OPC 1
Operation complete. All the previous commands
including the *OPC command are executed.
1 Not used 0 Always be 0.
2 QYE 4
Query error. The power supply tries to read the output
buffer but it is empty; or the system receives a new
command before the previous query command is read;
or both the input and output buffers are full.
3 DDE 8 Device error. Self-test or calibration error occurs.
4 EXE 16
Execution error (include trigger ignore, initialization
ignore, setting conflict, data overrange, data too long
and invalid parameter value).
5 CME 32 Command error. Command syntax error occurs.
6 Not used 0 Always be 0.
7 PON 128
Power-on inspection. Turn off the power supply after
the event register is read or cleared and then turn on
the power supply.
