9.8.2 General I/Q settings
Access:
► Select "SGMA-GUI > Instrument Name > I/Q Settings > General".
Comprises the settings for setting the state and the analog wideband I/Q input.
Mod State
Switches the I/Q modulation on and off.
Remote command:
[:SOURce]:IQ:STATe on page 270
I/Q Wideband
Setting mode for wideband modulation signals (higher I/Q modulation bandwidth).
The modulation frequency response of the R&S SGS in the useful bandwidth is
improved at the expense of poorer harmonic suppression. Improvement is achieved by
shifting the switching frequencies of the low pass filters in the output section.
