*CLS
Description:
Erases all the Event registers, all Condition registers, the Error Queue and the
Status Byte Register.
**********************************************
*ESE <numeric_value>
Description:
Sets the Standard Event Enable Register.
This command is sent with the decimal equivalent of the binary value that
determines the desired state (0 or 1) of the bits in the register.
This register is used as a mask fort the Standard Event Status Register. When a
standard event is masked (disables), the occurrence of that event will not set the
Event Summary Bit (ESB) in the Status Byte Register. Conversely, when a standard
event is unmasked (enabled), the occurrence of that event will set the ESB bit.
A cleared bit (bit set to 0) in the enable register will prevent (mask) the ESB bit in the
Status Byte Register from setting when the standard event occurs. A set bit (bit set
to 1) in the enable register will allow (enable) the ESB bit to set when the
corresponding standard event occurs.
Refer to Figure 4-3.
Parameter:
<numeric_value>
= 0
Clear register.
= 1
Set OPC (B0) of enable register
= 4
Set QYE (B2) of enable register
= 8
Set DDE (B3) of enable register
= 16
Set EXE (B4) of enable register
= 32
Set CME (B5) of enable register
The sum of the decimal weights of the bits that you wish to be set is the value that is
sent with the *ESE command. For example, to set the CME and QYE bits of the
Standard Event Enable Register, send the following command:
*ESE 36
