Measurement Operations & Settings

 

 

 

 

 

command:

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

 

 

 

syntax:

[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:STOP?[<wsp>MINMAX]

 

description:

Returns the end point of the sweep.

 

parameters:

optional

MIN Returns the minimum start wavelength available.

 

 

 

This value is wavelength dependent.

 

 

 

MAX Returns the maximum start wavelength available.

 

 

 

This value is wavelength dependent.

 

response:

The wavelength at which the sweep ends as a float value in meters.

 

example:

wav:swe:stop? → +1.55000000E-006<END>

 

affects:

All tunable laser modules

 

 

 

 

 

 

 

 

 

command:

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

 

 

 

syntax:

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

 

 

STOP0STARt1PAUSe2CONTinue3

 

description:

Stops, starts, pauses or continues a wavelength sweep.

 

parameters:

0 or STOP:

Stop the sweep.

 

 

1 or STARt:

Start a sweep, run sweep.

 

 

2 or PAUSe:

Pause the sweep. (doesn’t apply for continuous sweep)

 

 

3 or CONTinue:

Continue a sweep. (doesn’t apply for continuous sweep)

 

N O T E

If you enable lambda logging (see

 

 

“[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:LLOGging” on page 140 ) and modulation

 

 

(see “[:SOURce[n]][:CHANnel[m]]:AM:STATe[l]” on page 117 ) simultaneously, a sweep can-

 

 

not be started.

 

 

N O T E

Generally, a continuous sweep can only be started if:

 

 

the trigger frequency, derived from the sweep speed and sweep step, is <= 40kHz

 

 

the number of triggers, calculated from the sweep span and sweep span, is <=100001

 

 

the start wavelength is less than the stop wavelength.

 

 

In addition, a continuous sweep with lambda logging requires:

 

 

the trigger output to be set to step finished

 

 

modulation set to coherence control or off.

 

response:

none

 

 

example:

wav:swe STOP

 

 

affects:

All tunable laser modules
