internal digital modulation
coherence control
external analog modulation
external digital modulation
wavelength locking
external digital modulation using Input Trigger Connector
NOTE 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.
response: none
example: sour2:am:sour int
affects: 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.
command:
[:SOURce[n]][:CHANnel[m]]:AM:SOURce[l]?
syntax: [:SOURce[n]][:CHANnel[m]]:AM:SOURce[l]?
description: Returns the type or source of the modulation of the laser output.
parameters: none
NOTE 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.
