[:SOURce[n]][:CHANnel[m]]:AM[:INTernal]:FREQuency[l]<wsp><frequency>
[THZ|GHZ|MHZ|KHZ|HZ]
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 la-
ser source. The default value of [l] is 1, the lower wavelength source. The upper wave-
length source is denoted by 2.

[:SOURce[n]][:CHANnel[m]]:AM[:INTernal]:FREQuency[l]?
[:SOURce[n]][:CHANnel[m]]:AM[:INTernal]:FREQuency[l]? [MIN|DEF|MAX]
Returns the frequency of the amplitude modulation as a float value in Hertz.
MIN: minimum modulation frequency
MAX: maximum modulation frequency
DEF: This is not the preset (*RST) default value but is half the sum of, the minimum modu-
lation frequency and the maximum modulation frequency
Use [l] to query 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-wave-
length laser source. The default value of [l] is 1, the lower wavelength source. The upper
wavelength source is denoted by 2.
