 Coupling 

SCPI: 

FM:FILTer:HPASs 

 

<num> sets the AC bandwidth to 100 

 for any value   1 

and sets the AC bandwidth to 20 Hz for any value   1 

Analyzer: 

NONE

FM Coupling DC

This 

 (Option 002 only) lets you set the FM input to be

DC-coupled. Use DC coupling for modulation rates below 100 

In this mode, the phase-locked loop is de-activated. This means that
the synthesizer is operating as an open loop sweeper. The synthesizer
will not be phase locked, and therefore, be aware that the phase noise
and CW frequency accuracy specifications do not apply.

An asterisk next to the key label indicates that DC FM coupling is
selected. The factory preset default is AC coupling.

For synthesizers 

 Option 002, see FM On/Off DC.
