Source Specific 
Command 
Description
Sets or queries the modulation source as internal 
or external. Internal is the default modulation 
source. 
Note
If an external modulation source is selected, 
modulation depth is limited to ± 5V from the MOD 
INPUT terminal on the rear panel. For example, if 
modulation depth is set to 100%, then the 
maximum amplitude is +5V, and the minimum 
amplitude is -5V.
