Operators Manual 

6-52 

Check the Calibrator Status 

The controller has access to six status registers for the 5730A Calibrator, which indicate 
the Calibrator conditions in the as shown in Figure 6-1. Each register bit is explained 
under separate headings for each register. Table 6-9 lists each register and its remote 
commands. 

In addition to the status registers, the Service Request control line, SRQ (available only 
when an IEEE-488 controller is used) and a 16-element buffer called the Fault Queue 
provide status information.
