<name> Name parameter — Select a parameter name from a listed group.
<name> = NEVer
:CALCulate:FORMat MXB
<NRf> Numeric representation format — A number that can be expressed
as an integer (e.g., 8) a real number (e.g., 23.6) or an exponent
(2.3E6).
:TRACe:POINts 20
<NDN> Non-decimal numeric — A non-decimal value that can be used to
program status enable registers. A unique header identifies the

ter is used, the instrument is programmed to the lowest allowable
value. When the MAXimum parameter is used, the instrument is
programmed to the largest allowable value.
