Optimizing I/Q modulation performance

With its default settings, the I/Q Modulator provides vector modulated signal that is
optimized for time sensitive measurements and lower noise.

Adjusting the settings helps to improve signal quality in the following cases:

●

To optimize the intermodulation characteristics of the signal

●

To optimize the signal-to-noise ratio (SNR) of the signal

●

To improve the flatness of the RF signal

In the following examples, we assume that:

●

The R&S

SMM100A generates a baseband signal

●

A spectrum analyzer is connected to the R&S

SMM100A, the analyzed is config-

ured, and measures the required signal characteristics.

To improve signal flatness

For a given baseband signal and RF frequency, perform the following:

1. In the block diagram, select "I/Q Mod > I/Q Settings > I/Q Modulator > On".

The I/Q modulator is enabled. Modulated is the internal baseband signal.
This mode generates flat signal but requires longer settling time and leads to signal
interruption.

2. Select "Optimization Mode > High Quality"

Note:

Do not use the mode "I/Q Modulator > Optimization Mode > High Quality" in combi-
nation with the modes "RF Level > Setting Characteristics > Uninterrupted/Strictly
Monotone".
The high quality I/Q optimization leads to RF signal interruption. The requirements
of the RF level modes "Uninterrupted" and "Strictly Monotone" can not be fulfilled.

3. On a connected signal analyzer, monitor the signal characteristics.

To optimize the intermodulation characteristics of signal

For a given baseband signal and RF frequency, perform the following iterative steps:

1. In the block diagram, select "I/Q Mod > I/Q Settings > I/Q Modulator > On".

The I/Q modulator is enabled. Modulated is the internal baseband signal.

2. If activated, disable the "I/Q Wideband > Off".

3. Select "Baseband Gain = - 2 dB".

4. On a connected signal analyzer, monitor the signal distortion characteristics.
