I/Q Modulation
I/Q modulation can improve the spectrum utilization. In IQ modulation, two
orthogonal carrier signals (with the same frequency and 90° phase difference,
generally expressed with Sin and Cos) are modulated with the I (In-Phase
component) and Q (Quadrature Phase component) signals respectively and then
they are transmitted together. This function is only available for DSG3065B-IQ and
DSG3136B-IQ. This function only supports the frequency band below 6.5 GHz.
To Enable I/Q Modulation
Press I/Q → Switch to select "On" or "Off".
⚫ On: enable the I/Q modulation function. The backlight of I/Q lights on, and the
I/Q label is displayed in the function status area in the user interface.
⚫ Off: disable the I/Q modulation function and this is the default state.
NOTE: When a sweep type is selected, if the step sweep time is smaller than 50 ms
and I/Q modulation is turned on, "You can turn on the IQ Mode when sweep time is
greater than 50ms" will be displayed in the user interface.
To Select the Modulation Source
Press I/Q → Source to select "Int" or "Ext" modulation source.
1. Internal Source
When "Int" is selected, the built-in baseband generator (wavetable) provides the
modulating signal. At this point, if the baseband output switch is turned on, the
RF signal generator will output the I (In-Phase) components and Q (Quadrature
Phase) components of the I/Q modulation baseband signal from the [I OUT]
and [Q OUT] connectors (as shown in the figures below) on the rear panel.
2. External Source
When "Ext" is selected, the RF signal generator receives the in-phase baseband
signal and quadrature phase modulating signal of the I/Q modulation input from
the [I IN] and [Q IN] connectors (as shown in the figures below) on the rear
panel.
