Sets the frequency of the amplitude modulation of the laser output.

The frequency as a float value in Hz.

Also allowed are: MIN: minimum programmable value MAX: maximum programmable value

DEF: This is not the preset (*RST) default value but is half the sum of, the minimum programmable value and the maximum programmable value

The default units are HZ, although KHZ, MHZ, GHZ, and THZ can also be specified.

The resolution of the frequency is always 1 Hz.

Use [l] to set the modulation frequency 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.
