rounds the parameter. For example, if an instrument has a programmable output impedance of 50 or 75 ohms, you specified

76.1for output impedance, the value is rounded to 75. If the

instrument setting can only assume integer values, it automatically rounds the value to an integer. For example, sending *ESE 10.123 is the same as sending *ESE 10.

Extended Numeric Parameters. Most measurement related subsystems use extended numeric parameters to specify physical quantities. Extended numeric parameters accept all numeric parameter values and other special values as well. All extended numeric parameters accept MAXimum and MINimum as values. Other special values, such as UP and DOWN may be available as documented in the instrument’s command dictionary. Note that MINimum and MAXimum can be used to set or query values. The query forms

are useful for determining the range of values allowed for a given parameter.

In some instruments, extended numeric parameters accept engineering unit suffixes as part of the parameter value. Refer to the command summary to see if this capability exists.

Note that extended numeric parameters are not used for common commands or STATUS subsystem commands.
