Output Table
Output Table for the AOP:
Command, Aux Command Information, Parameter ID, and Parameter Value, are used to send commands to
the instrument, write new parameter values, read existing parameter values, or read data values. The
Command is a 16-bit value used for the command string as shown above in the command section.
The 16-bit Aux Command Information is used for specific information required for special commands. To
select which parameter is being read or written, set the predefined number into the Parameter ID. If the
value is being read, then the Parameter Value is ignored, or set to the required value if the value is being
written.
The following values: Reserved 1, Reserved 2, Reserved 3, Reserved 4, Reserved 5, Reserved 6, and
Reserved 7, are reserved to provide padding so the user selectable read only parameters are aligned
between the output and input tables. The other two values Parameter RD1 ID and Parameter RD2 ID are
user selectable parameter ID values which are used to read values from the instrument. These read values
can be anything from an instrument specific measurement such as Num Averages to a parameter value such
as Waversaver.
