Status Reporting

∙Bit 3 (Device-Specific Error) is an event bit which indicates an operation did not properly complete due to some condition of the Counter.

Errors -300 through -399 and all those with positive error numbers (+2000 through ...) are device-specific errors.

∙Bit 4 (Execution Error) is an event bit which indicates that a command could not be executed 1) because the parameter was out of range or inconsistent with the Counter ’s capabilities, or 2) because of some condition of the Counter.

Errors -200 through -299 are execution errors.

∙Bit 5 (Command Error) is an event bit which indicates one of the following has occurred: 1) an IEEE 488.2 syntax error, 2) a semantic error indicating an unrecognized command, or 3) a Group Execute Trigger was entered into the input buffer inside of a program message.

∙Bit 6 is not used.

∙Bit 7 (Power On) is an event bit which indicates that an off-to-on transition has occurred in the Counter ’s power supply.

Standard Event Status Enable Register

The Standard Event Status Enable Register selects which events in the Standard Event Status Register are reflected in the ESB summary bit (bit 5) of the Status Byte Register as shown in

Figure 3-8.

Use *ESE to write to this register and *ESE? to read this register.

Use *ESE 0 to clear the register. (Power-on also clears this register.)
