Standard Event Status Register
The Standard Event Status Register of the Tester is used to
determine the specific event that set bit 5 in the status byte
register as follows:
Figure 4-8 Standard Event Status Register
The Standard Event Status Register contains the following
information:
To query the Standard Event Status Register, send the
command
*ESR?
. The response is the decimal sum of the bits
which are set to
1
. For example, if the bit 7 and bit 3 are set to
1
,
the decimal sum of these 2 bits is 136 (128 plus 8) see
Figure 4-5 . So the decimal value 136 is returned.

Bit Description
0 If all pending operations is completed following execution of the
*OPC
command, this bit is set to
1
.
1 This bit is always set to
0
.
2 If a query error has occurred, this bit is set to
1
.
3 If a device dependent error has occurred, this bit is set to
1
. Device dependent errors have error numbers from
-399
to
-300
and
1
to
32767
.
4 If an execution error has occurred, this bit is set to
1
.
Execution errors have error numbers from
-299
to
-200
.
5 If a command error has occurred, this bit is set to
1
.
Command errors have error numbers from
-199
to
-100
.
6 This bit is always set to
0
.
7 If the instrument has been turned off and then on, this bit is set to
1
.
