Operation of the Standard Event Register
The standard event register is provided for eight
different kinds of event which can occur inside the
instrument. Bit 5 (ESB) of the status byte is set to 1
when any of the bits in this register becomes 1 (or
when the corresponding bit of the standard event
enable register becomes 1).
Example
1. A query error occurs.
2. Bit 2 (QYE) is set to 1.
3. Bit 5 (ESB) of the status byte is set to 1 if bit 2 of
the standard event enable register is 1.
It is also possible to check what type of event has
occurred inside the instrument by reading the contents
of the standard event register.
Reading from the Standard Event
Register
The contents of the standard event register can be
read by the *ESR command. After the register is read,
it is cleared.
Clearing the Standard Event Register
The standard event register is cleared in the following
three cases.
• When the contents of the standard event register
are read using the *ESR command.
• When a *CLS command is received.
• When the instrument is power cycled.
