Status Reporting

Accessing the Standard Event Status Register Group’s

Registers

The following sections show the syntax and give programming

examples (using the IBASIC programming language) for the Common

Commands used to access the Standard Event Status Register Group’s

registers.

3 8 Device

Dependent

Error

1 = A Test Set dependent error has occurred. This

means that some Test Set operation did not execute

properly due to some internal condition, such as

overrange. This bit indicates that the error was not

a command, query, or execution error.

2 4 Query Error 1 = An error has occurred while trying to read the

Test Set’s Output Queue. The following events

cause a query error:

• An attempt is being made to read data from the

Output Queue when no data is present or

pending.

• Data in the Output Queue has been lost. An

example of this would be Output Queue

overflow.

12Request

Control

1 = The Test Set is requesting permission to become

the Active Controller on the HP-IB bus.

01Operation

Complete

1 = The Test Set has completed all selected pending

operations and is ready to accept new commands.

This bit is only generated in response to the *OPC

IEEE 488.2 Common Command.
