External Φ Modulation Source Coupling
:PM[1]|2:EXTernal[1]|2:COUPling AC|DC
:PM[1]|2:EXTernal[1]|2:COUPling?
This command sets the external coupling for the phase modulation source if
:PM[1]|2:SOURCe was selected external. The choices are AC or DC coupling. This
command does not change the currently active source, nor does it switch the current
modulation on or off. The modulating signal may be the sum of several signals, either
internal or external sources. If the coupling is set to DC, then both the AC and DC signal
components pass. AC coupling passes only AC signal components.
