Operation and Questionable Status Registers
The operation and questionable status registers are registers that
monitor the overall instrument condition. They are accessed with the
STATus:OPERation and STATus:QUEStionable commands in the
STATus command subsystem. See the figure on page 353.
Operation Status Register
The operation status register monitors the current instrument
measurement state. It checks to see if the instrument is calibrating,
sweeping, or waiting for a trigger. For more information see the *OPC?
command located in the IEEE Common Commands section.
