INTernal
Explanation
EXTernal: select "Ext" modulation source. At this point, the RF signal generator
receives the In-Phase baseband signal and Quadrature Phase modulating signal
of IQ modulation inputted from the [I IN] and [Q IN] connectors at the rear
panel. When external baseband signal is inputted and the baseband output
switch is turned on, the RF signal generator can output the I (In-Phase) and Q
(Quadrature Phase) components of the IQ modulation baseband signal
generated by the built-in baseband generator (wavetable) respectively from the
[I OUT] and [Q OUT] connectors at the rear panel.
INTernal: select "Int" modulation source. At this point, the built-in baseband
generator (wavetable) of the instrument provides the modulating signal. If the
IQ modulation switch is already turned on, the baseband output switch will be
turned on automatically. The RF signal generator can output the In-Phase and
Quadrature Phase components of the IQ modulation baseband signal
respectively from the [I OUT] and [Q OUT] connectors at the rear panel.
Return Format
The query returns the type of IQ modulation source. For example, INT.
Example
:IQ:MOD INT
:IQ:MOD?
