9. Status Reporting
9.1 Introduction
This chapter covers the status data structure of Chroma 63800 series electronic load as
shown in Figure 9-1 (on the next page). The standard registers, such as the Event Status
register group, the Output Queue, the Status Byte and Service Request Enable registers
perform standard GPIB functions and are defined in IEEE-488.2 Standard Digital Interface for
Programmable Instrumentation. Other status register groups implement the specific status
reporting requirements for the electronic load.
9.2 Register Information in Common
 Condition register
The condition register represents the present status of electronic load signals. Reading the
condition register does not change the state of its bits. Only changes in electronic load
conditions affect the contents of this register.
 Enable register
The Enable register can be programmed to enable which bit in the corresponding Event
register is logically ORed into the Channel Summary bit.
