SCPI Condition Register
You can obtain the state of the power supply and read parameters from the operation register. The different states
of the power supply can be read from 7 condition registers. These registers are status byte register, standard event
register, quest condition register and operation status register. The status byte register stores the information of 3
other registers. The following table provides the details on each register’s meaning.
