Figure 20: Complex modulated waveform tab
Only relevant parameters and edition fields are shown in the GUI at any time depending
on the selected generation mode (RF or I/Q) and modulation scheme.
Waveform Destination Section
Generate I/Q Data
If checked baseband (I/Q) signals will be generated.
I/Q Toggle buttons
I/Q selection toggle buttons for each channel will be shown when the
Generate I/Q Data checkbox is checked. In-Phase (I) and Quadrature (Q)
components can be independently assigned to each channel.
Apply Offset Freq.
This checkbox is only active for the I/Q Data Generation mode and it applies a
frequency shift to the signal according to the ‘Offset Freq.’ edition field.
Frequency shift, unlike carrier frequency, may be positive or negative.
Spectrum Reversed
This checkbox must be selected for generation of signals in the second
Nyquist band (FS/2 – FS). Its effect is the reversion of the fundamental signal
(in the 1st Nyquist Band) in the frequency domain. It also reverses the effect of
any correction so correction factors obtained for the second Nyquist band will
be applied appropriately.
