I/Q control can be swapped in the lower section of the menu and the optimized settings
for wideband modulation signals can be activated.
The bottom section of the menu differs depending on the selected input signal ("Analog
Wideband I/Q Input" or "Internal Baseband").
The crest factor is input for the external signal.
5.6.2.1 General I/Q Mod Settings
IQ Source - I/Q Mod
Selects the input signal for the I/Q modulator.
"Analog Wide-
band I/Q In" Selects an external analog signal as the input signal. The signal must
be applied at the inputs I and Q.
"Internal Base-
band I/Q In" Selects the internal baseband signal as the input signal. This setting
requires the additional equipment options for generating the various
baseband signals.
Remote command:
[:SOURce<hw>]:IQ:SOURce

State - I/Q Mod
Activates/deactivates I/Q modulation.
If "Analog Wideband I/Q In" is selected, the I/Q modulator is also deactivated and acti-
vated.
If "Internal Baseband I/Q In" is selected, the I/Q modulator is always activated automat-
ically as soon as signal generation is activated in the "Baseband" block. It can, how-
ever, be deactivated later, e.g. if only the baseband signal which is output at the I/Q
outputs is relevant.
