[:SOURce<hw>]:IQ:WBSTate <Wbstate>
This command selects optimized setting for wideband modulation signals (>5 MHz)
(State ON).
Parameters:
0|1|OFF|ON
OFF
<Wbstate>
*RST:
IQ:WBST ON
activates optimized setting for wideband signals.
Example:
[:SOURce<hw>]:BB:IQGain <Iqgain>
This command specifies the baseband gain for the internal baseband signal.
This command specifies the baseband gain for the internal or in case of two-path instru-
ments, external baseband signal.
Thus, the modulation of the I/Q modulator can be optimized for any measurement
requirement. The gain settings for an external analog wideband signal (Analog Wide-
band I/Q In) are performed with command :SOURce:IQ:GAIN
Parameters:
AUTO|DBM3|DB0|DB3|DB6
AUTO
Activates automatic setting. The modulation is automatically
optimized for the internally set baseband signal
DBM3
Activates -3 dB gain.
With this setting, signal distortions are minimized.
DB0
Activates 0 dB gain (standard settings).
DB3
Activates 3 dB gain.
DB6
Activates 6 dB gain.
With this setting, signal noise is minimized.
0.01 dB
AUTO
<Iqgain>
Increment:
*RST:
IQ:SOUR BAS
selects the internal baseband signal as the input signal of the I/Q
modulator.
BB:IQG DB6
sets gain 6dB (best for low noise).
