Setting any bit of the Standard Event Status Enable Register to 1
enables access to the corresponding bit of the Standard Event Status
Register.
Standard Event Status Register (SESR) and Standard Event Status
Enable Register (SESER)
Device-Specific Event Status Registers (ESR0 and ESR1)
This instrument provides two event status registers for controlling
events.
Each event register is an 8-bit register.
When any bit in one of these event status registers enabled by its
corresponding event status enable register is set to 1, the following
happens:
For Event Status Register 0, bit 0 (ESB0) of the Status Byte Register
is set to 1.
For Event Status Register 1, bit 1 (ESB1) of the Status Byte Register
is set to 1.
Event Status Registers 0 and 1 are cleared in the following situations:
When a
*CLS command is executed
When an Event Status Register query
(
:ESR0? or :ESR1?) is executed
When the instrument is powered on
