Status Reporting
Status reporting is used to monitor the power meter to determine when
events have occurred. Status reporting is accomplished by configuring and
reading status registers. The power meter has the following main
registers:
• Status Register
• Standard Event Register
• Operation Status Register
• Questionable Status Register
• Device Status Register
There are a number of other registers “behind” these. These are described
later.
The Status and Standard Event registers are read using the IEEE-488.2
common commands. These are the most commonly used registers and are
described in detail in this section.
The Operation and Questionable Status registers are read using the SCPI
STATus command subsystem.
