Bits B8 through B15 are not shown since they are not used.
Values
are:
1 = Enable Standard Event
0 = Disable (Mask) Standard Event
Events
are:
PON = Power On
URQ = User Request
CME = Command Error
EXE = Execution Error
DDE = Device-dependent Error
QYE = Query Error
OPC = Operation Complete
Example
*ESE 36
Sets the
CME
and
QYE
bits of the standard
event enable register, where:
CME (Bit B5) =
32
QYE (Bit B2) =
4
<NRf> = 3

*ESR? (event status register query)
This command reads the standard event status register and clears it.
Details
This command is used to acquire the value (in decimal) of the standard event status register (see the
following table). The binary equivalent of the returned decimal value determines which bits in the
register are set. This register is cleared on power-up or when
*CLS
is sent.
A set bit in this register indicates that a particular event has occurred. For example, for an acquired
decimal value of 48, the binary equivalent is 00110000. For this binary value, Bits B4 and B5 of the
standard event status register are set. These set bits indicate that a device-dependent error and
command error have occurred.
