Using Status Registers
The Analyzer's Status Register Sets
Execution Error
(bit 4) is set to 1 when the command parser detects an execution
error. Execution errors occur when the following conditions
occur:
• a <PROGRAM DATA> element received in a command
• the analyzer could not execute a valid command due
Command Error
(bit 5) is set to 1 when the command parser detects a command
error. The following events cause a command error:
• An IEEE 488.2 syntax error occurred. This means
• A semantic error occurred. For example, the
User Request
(bit 6) is not implemented. For keypress related functions, see
"Device Status Register Set" on page
Power On
(bit 7) is set to 1 when you turn on the analyzer.
The commands used to read and write the Standard Event
Status registers are listed below:
*ESR?
*ESE <num>
*ESE?

follow the syntax defined by the 488.2 standard.
analyzer received an incorrectly spelled command.
Another example would be that the analyzer
received an optional 488.2 command that it does not
implement.
