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
was outside the legal range for the analyzer, or
inconsistent with the operation of the analyzer.
• the analyzer could not execute a valid command due
to some analyzer condition.
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
that the analyzer received a message that did not
follow the syntax defined by the 488.2 standard.
• A semantic error occurred. For example, the
analyzer received an incorrectly spelled command.
Another example would be that the analyzer
received an optional 488.2 command that it does not
implement.
User Request
(bit 6) is not implemented. For keypress related functions, see
“Device Status Register Set” on page 5-15
.
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?
reads the value of the standard event status
register.
*ESE <num>
sets bits in the standard event status enable
register. The current setting of the standard
event statue enable register is stored in
non-volatile memory. If
*PSC
has been set, it
will be saved at power on.
*ESE?
reads the current state of the standard event
status enable register.
