Note:
Internal regulation functions based on the LMX controller such as CSC mode are not
in effect in this mode of operation.
7.9.1.3
Amplitude Modulation Mode (AM)
In AM mode, the internal control waveform amplitude is modulated by the external input
signal. Signal input range is ±10Vpk and gain is 1.0 so max modulation depth is proportional
to the analog input signal amplitude.

7.9.1.4
Analog Addition Mode (ADD)
In ADD mode, the external input signal is summed with the internal waveform reference and
the sum of both signals is produced at the output of the LMX.
