Signal Generation – The SOURce Subsystem

command:

[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:DWELl

 

syntax:

[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:DWELl<wsp>

 

<value>MINMAXDEF[NSUSMSS]

description:

Sets the dwell time. Can only be used when sweep is stepped.

N O T E

Cannot be set while a sweep is running.

parameters:

The dwell time as a float value.

 

If you specify no units in your command, seconds are used as the default.

 

Also allowed are: MIN: minimum programmable value

 

MAX: maximum programmable value

 

DEF: This is not the preset (*RST) default value but is half the sum of, the

 

minimum programmable value and the maximum programmable value

response:

none

example:

wav:swe:dwel 500ms

affects:

All tunable laser modules

 

 

 

 

command:

[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:DWELl?

 

syntax:

[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:DWELl?[<wsp>MINMAXDEF]

description:

Returns the dwell time. Can only be used when sweep is stepped.

parameters:

none

 

Also allowed are: MIN: minimum programmable value

 

MAX: maximum programmable value

 

DEF: This is not the preset (*RST) default value but is half the sum of, the

 

minimum programmable value and the maximum programmable value

response:

The dwell time in seconds.

example:

wav:swe:dwel? → +5.00000000E-001<END>

affects:

All tunable laser modules

affects:

[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:EXPectedtriggers?

[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:EXPectedtriggers?

Returns the number of triggers. A tunable laser wavelength sweep causes a number of trig- gers, this number is required to configure a triggering data acquisition function on a power meter. The number returned by this function can be used to configure a Power Meter for co- ordinated measurements with a tunable laser source (see command “:SENSe[n][:CHANnel[m]]:FUNCtion:PARameter:LOGGing” on page 94).

none

the number of expected triggers as an unsigne integer value.

sour0:wav:swe:exp? → 12001

All tunable laser modules except Agilent 81649A and Agilent 81689A/B
