Product-Specific Commands—Description
:SENSe[1..n][:WAVelength]:STARt
Description This command sets instrument sweep stop
wavelength.
At *RST, this value is set to 1525.0 nm.
Syntax :SENSe[1..n][:WAVelength]:STARt<wsp><Start[<
wsp>M]>|MAXimum|MINimum|DEFault
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 M. 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 wavelength value.
The SENSe[1..n][:WAVelength]:STARt? MIN and
SENSe[1..n][:WAVelength]:STARt? MAX queries
can be used to determine valid sweep start
wavelength range.
