T200S Specific Commands
[SOURce]:WAVelength:SWEep:STARt
Description
This command sets the start wavelength of a swept signal.
At *RST, this value will be set to MINimum.
Syntax [:SOURce]:WAVelength:SWEep:STARt<wsp><start>[<unit>]|
MAXimum|MINimum|DEFault
Parameter(s)
³
start :
Value corresponding to the start wavelength in meter (if no
unit is specified).
To known the valid wavelength range, use the query
[SOURce]:WAVelength:SWEep:STARt?
on page 123 (MIN and
MAX parameters).
³
unit
:
Unit of the start wavelength: M preceded by a possible
multiplier. Possible multipliers are listed in Unit Multipliers on
page 52.
³
MAXimum
Sets the start wavelength to the maximum possible value.
³
MINimum
Sets the start wavelength to the minimum possible value.
³
DEFault
Sets the start wavelength to the default value.
To known the default wavelength, use the query
[SOURce]:WAVelength:SWEep:STARt? on page 123 (DEF
parameter).
Example(s)
SOUR:WAV:SWE:STAR 1435 NM
SOUR:WAV:SWE:STAR? returns 1.435000E-006
