[:SOURce[n]][:CHANnel[m]]:FM:SBSCtrl:Level[l]?
[:SOURce[n]][:CHANnel[m]]:FM:SBSCtrl:LEVel[l]?<wsp>[MIN|MAX|DEF]
Queries the currently set excursion level of the SBS Control frequency modulation.
Optional
Returns the currently set excursion level as a percentage of its maximum value.

sour2:fm:sbsc:lev? +8.000E+01<END>
Agilent 81980A, 81940A, 81989A, 81949A compact tunable lasers.
[:SOURce[n]][:CHANnel[m]]:MODout
[:SOURce[n]][:CHANnel[m]]:MODout<wsp>FRQ|FRQRDY|0|1
Sets the modulation output mode of the BNC connector on the front panel of tunable laser
modules.
FRQ or 0: modulation signal is output all the time
FRQRDY or 1: modulation is combined with the laser-ready signal.
In this case, the output is kept low when no optical signal is output (for
example, while the laser is settling after a change of wavelength).
none
sour0:mod 0
All tunable laser sources with BNC ouput connector.
[:SOURce[n]][:CHANnel[m]]:MODout?
[:SOURce[n]][:CHANnel[m]]:MODout?
Queries the modulation output mode of the BNC connector on the front panel of tunable la-
ser modules.
none
0: modulation signal is output all the time
1: modulation is combined with the laser-ready signal.
In this case, the output is kept low when no optical signal is output (for example, while
the laser is settling after a change of wavelength).
→
sour0:mod? 0<END>
All tunable laser sources with BNC output connector.
MIN: returns the minimum programmable value (0%)
MAX: returns the maximum programmable value (100%)
DEF: returns the default preset (*RST) value.
