Parameter(s) Start:
The program data syntax for <Start> is defined
as a <numeric_value> element followed by an
optional <SUFFIX PROGRAM DATA> element.
The allowed <SUFFIX PROGRAM DATA>
element is HZ. The <Start> special forms
MINimum, MAXimum and DEFault are accepted
on input.
MINimum allows to set the instrument to the
smallest supported value.
MAXimum allows to set the instrument to the
greatest supported value.
DEFault allows the instrument to select a value
for the <Start> parameter.
The <Start> parameter corresponds to a valid
sweep start frequency value.
The SENSe[1..n]:FREQuency:STARt? MIN and
SENSe[1..n]:FREQuency:STARt? MAX queries
can be used to determine valid sweep start
frequency range.
