[:SOURce:]FREQuency/?<wsp><C>,<S>,<D>,/<P>
<REAL>THz
Sets or queries the wavelength setting of a tunable laser port. Value format is in Tera Hertz.
Example: FREQ
192.15;
sets Laser Port 1,1,1 to 192.15THz.
[:SOURce:]FREQuency:LIMit?<wsp><C>,<S>,<D>
<REAL>THz
Queries the frequency setting limits of a tunable laser port. Value format is in Tera Hertz.
Example:
FREQ:LIM?;
queries Laser Port 1,1,1. 2 value Response with min and maximum limit:
191.1020,196.1020;
[:SOURce:]OFFset/?<wsp><C>,<S>,<D>,/<P>
<REAL>GHz
Sets or queries the frequency offset setting of a tunable laser port. Value format is in Giga Hertz.
Example:
OFF 11.15;
sets Laser Port 1,1,1 offset to 11.15THz. Value can be positive or negative.
[:SOURce:]OFFset:LIMit?<wsp><C>,<S>,<D>
<REAL>GHz
Queries the offset setting limits of a tunable laser port. Value format is in Giga Hertz.
Example:
OFF:LIM?;
queries Laser Port 1,1,1 Response
12;
It is a single value since the offset is
symmetrical to 0.
[:SOURce:]POWer/?<wsp><C>,<S>,<D>,/<P>
<REAL>dBm
Sets or queries the optical output power
target
setting of a tunable laser port. Value format is in dBm.
Example:
POW 11.15;
sets Laser Port 1,1,1 power of 11.15dBm
[:SOURce:]ActualPOWer?<wsp><C>,<S>,<D>
<REAL>dBm
Queries the
current
optical output power reading of a tunable laser port. Value format is in dBm.
Example:
APOW?; 11.15;
queries the Laser Port 1,1,1 answer is 11.15dBm
[:SOURce:]DITher/?<wsp> <C>,<S>,<D>,/<P>
1,0,-1
Sets or queries the dither state of a laser port. If
the feature is not available, “-1” is returned for queries
or an error for set commands. Example:
DITH 1;
enables Laser Port 1,1,1 dither.
[:SOURce:]LIMit?<wsp><C>,<S>,<D>
<REAL>
Query maximum tuning Parameters of Laser in location C-S-D in csv format.
<Minimum Frequency>,<Maximum Frequency>,<Fine tuning Range>,<Minimum Power>,<Maximum
Power>
Example:
LIM?;
queries Laser Port 1,1,1
[:SOURce:]CONFiguration/?<wsp><C>,<S>,<D>,/<P>
<REAL>
Set or Query current configuration of Laser in location C-S-D in csv format:
<Frequency>,<Offset>,<Output Power>,<Output state>,<Busy state>,< Dither state>,
Busy state : <INT> “1”,”0”, Only for query, if set is used, this parameter is omitted
Dither state: <INT> “1”,”0”,”-1” If queried and “-1” is reported, laser does not support this feature. If set
and laser does not support the feature, the parameter setting
must be “-1”.
Example read
:
SOUR:CONF? 1,2,3;
returns
191.42,10.134,6.12,0,1,-1;
The laser is set to 191.42THz, 10.134GHz FTF, 6.12dBm, output on (1) , not busy tuning (0), dither not
supported(-1)
Example write
:
SOUR:CONF 1,1,1,193,1,7,1,-1;
will set the to 193THz, Fine tuning 1GHz,
7dBm output power, 1: laser on, 1: dither not supported.
Note: For SC Type lasers, Frequency and offset cannot be changed within a single command. Use 2
commands to set them separately.
[:SOURce:]BUSY? <wsp><C>,<S>,<D>
<INT>
Query if laser port is currently tuned “1” or settled “0”.
