Enable Registers.
The enable registers determine whether certain events are reported to the Status
Byte Register and SRQ. This oscilloscope has the following enable registers.
z Event Status Enable Register (ESER)
z OPERation Enable Register
z QUEStionable Enable Register
z Service Request Enable Register (SRER)
When one of the bits of the enable registers is high and the corresponding bit in
the status register is high, the enable registers will perform a logical OR function,
the output that controls the set bit of the Status Byte Register is high.
Various commands set the bits in the enable registers. The following sections
describe the enable registers and the commands that set them.
Event Status Enable Register (ESER): The ESER controls which types of events
are summarized by the Event Status Bit (ESB) in the SBR. The bits of the ESER
correspond to the bits of the SESR.
Use the *ESE command to set the bits in ESER. Use the *ESE? command to read
it.
OPERation Enable Register: Even though the OPERation Enable Register is
present in this digital storage oscilloscope, the OPERation registers do not report
any conditions.
QUEStionable Enable Register: The QUEStionable Enable Register controls which
types of events are summarized by the QUES status bit in the SBR.
Service Request Enable Register (SRER): The SRER controls which bits in the
SBR generate a service request.
Use the *SRE command to set the SRER. Use the *SRE? command to read it.
