INT|INT1|INT2|COHC|AEXT|EXT|DEXT|WVLL|BACK|0|1|2|3|5|6
Selects the type or source of the modulation of the laser output.
0, INT1, or INTernal:
1, COHCtrl, or INT2:
2, AEXTernal, or EXT:
3 or DEXTernal:
5 or WVLLocking:
6 or BACKplane:
Use [l] to set the modulation source of the upper or lower wavelength laser source of a dual-
wavelength laser source or a return loss module with an internal dual-wavelength laser
source. The default value of [l] is 1, the lower wavelength source. The upper wavelength
source is denoted by 2.
none
sour2:am:sour int
All laser sources, DFB sources, and tunable laser modules can use internal digital modula-
tion; as can return loss modules containing an internal source.
DFB source and tunable laser modules can use coherence control.
Other modulation modes are only available with tunable laser modules.
[:SOURce[n]][:CHANnel[m]]:AM:SOURce[l]?
[:SOURce[n]][:CHANnel[m]]:AM:SOURce[l]?
Returns the type or source of the modulation of the laser output.
none
Use [l] to query the modulation source of the upper or lower wavelength laser source of a
dual-wavelength laser source or a return loss module with an internal dual-wavelength laser
source. The default value of [l] is 1, the lower wavelength source. The upper wavelength
source is denoted by 2.
0: internal digital modulation
1: coherence control
2: external analog modulation
3: external digital modulation
5: wavelength locking
6: external digital modulation using Input Trigger Connector
