[:SOURce[n]][:CHANnel[m]]:AM:STATe[l]

[:SOURce[n]][:CHANnel[m]]:AM:STATe[l]<wsp> OFFON01

Enables and disables amplitude modulation of the laser output.

A boolean value: OFF or 0: amplitude modulation disabled (default) ON or 1: amplitude modulation enabled.

Use [l] to enable/disable amplitude modulation for the upper or lower wavelength laser source of a dual-wavelength laser source or a return loss module with an internal dual-wave- length laser source. The default value of [l] is 1, the lower wavelength source. The upper wavelength source is denoted by 2.

When the internal modulation is selected, the Modulation Output on the front panel outputs a version of the modulating signal that has the same frequency and phase as the modulating signal, but has a fixed, TTL-level amplitude. You can use this to synchronize your external measuring equipment to your instrument.

To allow for your possible synchronization requirements, there are two ways in which the signal can be output. Either the signal is combined with the laser-ready signal, so that the output is kept low when there is no optical signal being output (for example, while the laser is settling after a change of wavelength). Or the modulation signal is output all the time. This is set by the :SOURCE:MODOUT command (see “[:SOURce[n]][:CHANnel[m]]:MODout” on page 121).

When you enable lambda logging, see

“[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:LLOGging” on page 140, and modulation simultaneously, a sweep cannot be started, see “[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:[STATe]” on page 145.
