Chapter 3 Programming Your Counter for Remote Operation
Status Reporting
Errors -400 through -499 are query errors.
• 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
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.)
