Status Register Structure Overview

The structure of the register groups used in the Test Set is based upon

the status data structures outlined in the IEEE 488 and SCPI 1994.0

Standards. There are two types of status data structures used in the

Test Set: status registers and status queues. The general models,

components, and operation of each type of status data structure are

explained in the following sections.
