vector modulations are used, such as BPSK, QPSK and QAM. For a digital sign al, it has
no concept of vect or. IQ modulation vectorially bridges digital signal and analog sign al.

As shown in the following figure, two signals, I and Q, are multiplied by Sin and Co s
respectively and then add the two together. The output is IQ modulated signal.

Chapter 5 IQ Modulation Output RIGOL

To Select IQ Modulation

Press Mod  Type  IQ to enable IQ modulation function.
 When Mod is enabled, Sweep or Burst will be disabled automatically (if

enabled currently).

 After IQ is enabled, the instrument will generate IQ modulated waveform with

the currently specified carrier and modulating waveform.

To Select Carrier Waveform Shape

The carrier wavefo rm shape f or IQ modulation could only be Sine waveform. To select
Sine waveform, press the front panel key Sine.

To Select Modulating Waveform Source

Press Mod  Source to select “Int” or “Ext” modulating waveform source.

1. Internal Source

After the “internal” source is selected, the generator outputs IQ modulation
waveform according to the current con figuration (Pattern, Rate, and IQ_Map).

As shown in the f ollowing figure, “Rate” is the trans mission rate of the code, “Pat”
is the currently selected code pattern, and “IQ Ma p” is the method used to convert
a digital signal into an analog signal. The generator operates using the code
pattern in “Pat” and the specified method in “IQ Map” to acq u ir e t wo modulating
signals, I and Q.
