SCPI Status Register
The status registers are used to record and determine the status of
the function generator.
The function generator has a number of register groups:
Questionable Status Registers
Standard Event Status Registers
Status Byte Register
As well as the output and error queues.
Each register group is divided into three types of registers: condition
registers, event registers and enable registers.
Register types
Condition
Register The condition registers indicate the state of the
function generator in real time. The condition
registers are not triggered. I.e., the bits in the
condition register change in real time with the
instrument status. Reading a condition register
will not clear it. The condition registers cannot be
cleared or set.
Event Register The Event Registers indicate if an event has been
triggered in the condition registers. The event
registers are latched and will remain set unless the
*CLS command is used. Reading an event register
will not clear it.
Enable Register The Enable register determines which status
event(s) are enabled. Any status events that are not
enabled are ignored. Enabled events are used to
summarize the status of that register group.
