10.14.3 SOURce:BB subsystem general commands

The following section describes the commands for setting the frequency shift and the
phase offset for the signal at the "Baseband" block output.
[:SOURce]:BB:FOFFset
[:SOURce]:BB:POFFset
[:SOURce<hw>]:BB:PGAin
[:SOURce]:BB:INFO:PSEQuencer?
[:SOURce]:BB:FOFFset <Foffset>
Sets the frequency offset for the baseband signal. The offset affects the signal on the
baseband block output. It shifts the useful baseband signal in the center frequency.
Parameters:
<Foffset>
Example:
Manual operation:
[:SOURce]:BB:POFFset <Phoffset>
Sets the relative phase offset of the baseband signal.
The phase offset affects the signal of the "Baseband Block" output.
Parameters:
<Phoffset>
Example:
Manual operation:
[:SOURce<hw>]:BB:PGAin <PGain>
The command sets the relative path gain for the selected baseband signal compared
to the baseband signals of the other baseband sources (external baseband). The gain
affects the signal on the "baseband block" output.
Parameters:
<PGain>
[:SOURce]:BB:INFO:PSEQuencer?
Returns the baseband pulse sequencer information.
