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

for output impedance, the value is rounded to 

If the

instrument setting can only assume integer values, it automatically
rounds the value to an integer. For example, sending 

 10.123

is the same as sending 

 10.

Extended Numeric Parameters. Most measurement related
subsystems use extended numeric parameters to specify physical
quantities. 

parameters accept all numeric

parameter values and other special values as well. All extended
numeric parameters accept 

 and 

 as values. Other

special values, such as UP and DOWN may be available as documented

in the instrument’s command dictionary. Note that 

 and

 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 

 subsystem commands.
