The Standard Operation Register
The Standard Operation register group is used to report when the
instrument is scanning. Any or all of these conditions can be reported to
the Standard Operation summary bit through the enable register. To set
the enable register mask, you must write a decimal value to the register
using the STATus:OPER:ENABle command.
