Status Reporting
The 5071A status registers conform to the SCPI and IEEE 488.2 standards
applicable with an RS-232C serial data-communications port. RS-232C does not
support serial poll, parallel poll, or SRQ. Instead, IEEE SRQ and RQS signals
will always have the same state, and will be reflected in the state of the (low
TRUE) status output port (rear-panel Status Output BNC connector).
The conditions under which the rear-panel Status Output goes active can be
programmed with the commands available in the SCPI STATus subsystem.
These commands are used in conjunction with IEEE 488.2 Common commands.
Refer to the next section of this chapter for information about, and examples of,
programmed rear-panel Status Output states. The status registers of the 5071A
are defined in tables 5-3, 5-4, 5-5, and 5-6 as follows:
